2015-02-21Merge tag 'clk-for-linus-3.20' of ↵Linus Torvalds
git://git.linaro.org/people/mike.turquette/linux Pull clock framework updates from Mike Turquette: "The clock framework changes contain the usual driver additions, enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based devices. Additionally the framework core underwent a bit of surgery with two major changes: - The boundary between the clock core and clock providers (e.g clock drivers) is now more well defined with dedicated provider helper functions. struct clk no longer maps 1:1 with the hardware clock but is a true per-user cookie which helps us tracker users of hardware clocks and debug bad behavior. - The addition of rate constraints for clocks. Rate ranges are now supported which are analogous to the voltage ranges in the regulator framework. Unfortunately these changes to the core created some breakeage. We think we fixed it all up but for this reason there are lots of last minute commits trying to undo the damage" * tag 'clk-for-linus-3.20' of git://git.linaro.org/people/mike.turquette/linux: (113 commits) clk: Only recalculate the rate if needed Revert "clk: mxs: Fix invalid 32-bit access to frac registers" clk: qoriq: Add support for the platform PLL powerpc/corenet: Enable CLK_QORIQ clk: Replace explicit clk assignment with __clk_hw_set_clk clk: Add __clk_hw_set_clk helper function clk: Don't dereference parent clock if is NULL MIPS: Alchemy: Remove bogus args from alchemy_clk_fgcs_detr clkdev: Always allocate a struct clk and call __clk_get() w/ CCF clk: shmobile: div6: Avoid division by zero in .round_rate() clk: mxs: Fix invalid 32-bit access to frac registers clk: omap: compile legacy omap3 clocks conditionally clkdev: Export clk_register_clkdev clk: Add rate constraints to clocks clk: remove clk-private.h pci: xgene: do not use clk-private.h arm: omap2+ remove dead clock code clk: Make clk API return per-user struct clk instances clk: tegra: Define PLLD_DSI and remove dsia(b)_mux clk: tegra: Add support for the Tegra132 CAR IP block ...
2015-01-30ARM: OMAP3: use clock data from TI clock driver for legacy bootTero Kristo
As the clock data is now available for the legacy boot also from the clock driver, use this rather than the data under the mach folder. This allows us to get rid of the old clock data completely.

2015-01-26ARM: OMAP2+: Add dm816x hwmod supportTony Lindgren
Add minimal hwmod support that works at least on dm8168. This is based on the code in the earlier TI CDP tree, and an earlier patch by Aida Mynzhasova <aida.mynzhasova@skitlab.ru>. I've set up things to work pretty much the same way as for am33xx. We are basically using cm33xx.c with a different set of clocks and clockdomains. This code is based on the TI81XX-LINUX-PSP-04.04.00.02 patches published at: http://downloads.ti.com/dsps/dsps_public_sw/psp/LinuxPSP/TI81XX_04_04/04_04_00_02/index_FDS.html Cc: Aida Mynzhasova <aida.mynzhasova@skitlab.ru> Cc: Brian Hutchinson <b.hutchman@gmail.com> Acked-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2015-01-26ARM: OMAP2+: Add clock domain support for dm816xAida Mynzhasova
This patch adds required definitions and structures for clockdomain initialization, so omap3xxx_clockdomains_init() was substituted by new ti81xx_clockdomains_init() while early initialization of TI81XX platform. Note that we now need to have 81xx in a separate CONFIG_SOC_TI81XX block instead inside the ifdef block for omap3 to avoid make randconfig build errors. This code is based on the TI81XX-LINUX-PSP-04.04.00.02 patches published at: http://downloads.ti.com/dsps/dsps_public_sw/psp/LinuxPSP/TI81XX_04_04/04_04_00_02/index_FDS.html Cc: Brian Hutchinson <b.hutchman@gmail.com> Cc: Paul Walmsley <paul@pwsan.com> Signed-off-by: Aida Mynzhasova <aida.mynzhasova@skitlab.ru> [tony@atomide.com: updated to apply, renamed to clockdomains81xx.c, fixed to use am33xx_clkdm_operations, various fixes suggested by Paul Walmsley] Reviewed-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2015-01-14ARM: OMAP2+: Fix ti81xx class typeTony Lindgren
Otherwise it will return true for cpu_is_omap34xx() which we don't want for the clocks and hwmod. It's closer to am33xx for the clocks and hwmod than to the omap34xx. We also want to be able to detect 814x and 816x separately as at least the clocks are different with 814x using a apll and 816x using a fapll for the source clocks. Note that we can also remove omap3xxx_clk_init() call as it's wrong and ti81xx are booting in device tree only mode.

2014-10-15Merge tag 'clk-for-linus-3.18' of ↵Linus Torvalds
git://git.linaro.org/people/mike.turquette/linux Pull clock tree updates from Mike Turquette: "The clk tree changes for 3.18 are dominated by clock drivers. Mostly fixes and enhancements to existing drivers as well as new drivers. This tag contains a bit more arch code than I usually take due to some OMAP2+ changes. Additionally it contains the restart notifier handlers which are merged as a dependency into several trees. The PXA changes are the only messy part. Due to having a stable tree I had to revert one patch and follow up with one more fix near the tip of this tag. Some dead code is introduced but it will soon become live code after 3.18-rc1 is released as the rest of the PXA family is converted over to the common clock framework. Another trend in this tag is that multiple vendors have started to push the complexity of changing their CPU frequency into the clock driver, whereas this used to be done in CPUfreq drivers. Changes to the clk core include a generic gpio-clock type and a clk_set_phase() function added to the top-level clk.h api. Due to some confusion on the fbdev mailing list the kernel boot parameters documentation was updated to further explain the clk_ignore_unused parameter, which is often required by users of the simplefb driver. Finally some fixes to the locking around the clock debugfs stuff was done to prevent deadlocks when interacting with other subsystems." * tag 'clk-for-linus-3.18' of git://git.linaro.org/people/mike.turquette/linux: (99 commits) clk: pxa clocks build system fix Revert "arm: pxa: Transition pxa27x to clk framework" clk: samsung: register restart handlers for s3c2412 and s3c2443 clk: rockchip: add restart handler clk: rockchip: rk3288: i2s_frac adds flag to set parent's rate doc/kernel-parameters.txt: clarify clk_ignore_unused arm: pxa: Transition pxa27x to clk framework dts: add devicetree bindings for pxa27x clocks clk: add pxa27x clock drivers arm: pxa: add clock pll selection bits clk: dts: document pxa clock binding clk: add pxa clocks infrastructure clk: gpio-gate: Ensure gpiod_ APIs are prototyped clk: ti: dra7-atl-clock: Mark the device as pm_runtime_irq_safe clk: ti: LLVMLinux: Move __init outside of type definition clk: ti: consider the fact that of_clk_get() might return an error clk: ti: dra7-atl-clock: fix a memory leak clk: ti: change clock init to use generic of_clk_init clk: hix5hd2: add I2C clocks clk: hix5hd2: add watchdog0 clocks ...
2014-09-29clk: ti: change clock init to use generic of_clk_initTero Kristo
Previously, the TI clock driver initialized all the clocks hierarchically under each separate clock provider node. Now, each clock that requires IO access will instead check their parent node to find out which IO range to use. This patch allows the TI clock driver to use a few new features provided by the generic of_clk_init, and also allows registration of clock nodes outside the clock hierarchy (for example, any external clocks.)

In order to handle errata I688, a page of sram was reserved by doing a static iotable map. Now that we use gen_pool to manage sram, we can completely remove all of these static mappings and use gen_pool_alloc() to get the one page of sram space needed to implement errata I688. omap_bus_sync will be NOP until SRAM initialization happens.

2014-08-08Merge tag 'dt-for-3.17' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device-tree changes from Olof Johansson: "Unlike the board branch, this keeps having large sets of changes for every release, but that's quite expected and is so far working well. Most of this is plumbing for various device bindings and new platforms, but there's also a bit of cleanup and code removal for things that are moved from platform code to DT contents (some OMAP clock code in particular). There's also a pinctrl driver for tegra here (appropriately acked), that's introduced this way to make it more bisectable. I'm happy to say that there were no conflicts at all with this branch this release, which means that changes are flowing through our tree as expected instead of merged through driver maintainers (or at least not done with conflicts). There are several new boards added, and a couple of SoCs. In no particular order: - Rockchip RK3288 SoC support, including DTS for a dev board that they have seeded with some community developers. - Better support for Hardkernel Exynos4-based ODROID boards. - CCF conversions (and dtsi contents) for several Renesas platforms. - Gumstix Pepper (TI AM335x) board support - TI eval board support for AM437x - Allwinner A23 SoC, very similar to existing ones which mostly has resulted in DT changes for support. Also includes support for an Ippo tablet with the chipset. - Allwinner A31 Hummingbird board support, not to be confused with the SolidRun i.MX-based Hummingboard. - Tegra30 Apalis board support" * tag 'dt-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (334 commits) ARM: dts: Enable USB host0 (EHCI) on rk3288-evb ARM: dts: add rk3288 ehci usb devices ARM: dts: Turn on USB host vbus on rk3288-evb ARM: tegra: apalis t30: fix device tree compatible node ARM: tegra: paz00: Fix some indentation inconsistencies ARM: zynq: DT: Clarify Xilinx Zynq platform ARM: dts: rockchip: add watchdog node ARM: dts: rockchip: remove pinctrl setting from radxarock uart2 ARM: dts: Add missing pinctrl for uart0/1 for exynos3250 ARM: dts: Remove duplicate 'interrput-parent' property for exynos3250 ARM: dts: Add TMU dt node to monitor the temperature for exynos3250 ARM: dts: Specify MAX77686 pmic interrupt for exynos5250-smdk5250 ARM: dts: cypress,cyapa trackpad is exynos5250-Snow only ARM: dts: max77686 is exynos5250-snow only ARM: zynq: DT: Remove DMA from board DTs ARM: zynq: DT: Add CAN node ARM: EXYNOS: Add exynos5260 PMU compatible string to DT match table ARM: dts: Add PMU DT node for exynos5260 SoC ARM: EXYNOS: Add support for Exynos5410 PMU ARM: dts: Add PMU to exynos5410 ...

Pull ARM updates from Russell King: - Major clean-up of the L2 cache support code. The existing mess was becoming rather unmaintainable through all the additions that others have done over time. This turns it into a much nicer structure, and implements a few performance improvements as well. - Clean up some of the CP15 control register tweaks for alignment support, moving some code and data into alignment.c - DMA properties for ARM, from Santosh and reviewed by DT people. This adds DT properties to specify bus translations we can't discover automatically, and to indicate whether devices are coherent. - Hibernation support for ARM - Make ftrace work with read-only text in modules - add suspend support for PJ4B CPUs - rework interrupt masking for undefined instruction handling, which allows us to enable interrupts earlier in the handling of these exceptions. - support for big endian page tables - fix stacktrace support to exclude stacktrace functions from the trace, and add save_stack_trace_regs() implementation so that kprobes can record stack traces. - Add support for the Cortex-A17 CPU. - Remove last vestiges of ARM710 support. - Removal of ARM "meminfo" structure, finally converting us solely to memblock to handle the early memory initialisation. * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (142 commits) ARM: ensure C page table setup code follows assembly code (part II) ARM: ensure C page table setup code follows assembly code ARM: consolidate last remaining open-coded alignment trap enable ARM: remove global cr_no_alignment ARM: remove CPU_CP15 conditional from alignment.c ARM: remove unused adjust_cr() function ARM: move "noalign" command line option to alignment.c ARM: provide common method to clear bits in CPU control register ARM: 8025/1: Get rid of meminfo ARM: 8060/1: mm: allow sub-architectures to override PCI I/O memory type ARM: 8066/1: correction for ARM patch 8031/2 ARM: 8049/1: ftrace/add save_stack_trace_regs() implementation ARM: 8065/1: remove last use of CONFIG_CPU_ARM710 ARM: 8062/1: Modify ldrt fixup handler to re-execute the userspace instruction ARM: 8047/1: rwsem: use asm-generic rwsem implementation ARM: l2c: trial at enabling some Cortex-A9 optimisations ARM: l2c: add warnings for stuff modifying aux_ctrl register values ARM: l2c: print a warning with L2C-310 caches if the cache size is modified ARM: l2c: remove old .set_debug method ARM: l2c: kill L2X0_AUX_CTRL_MASK before anyone else makes use of this ...

Besides that, there are a few things to point out: - Lots of platform conversion on OMAP2+, with removal of old board files for various platforms. - Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well - Some updates to pinctrl and other subsystems.

2013-10-22ARM: OMAP2+: add missing lateinit hook for calling pm late initNishanth Menon
AM335x, AM43xx, OMAP5 and DRA7 have missing late init hook. Introduce SoC specific hook with a call to OMAP2+ generic lateinit hook. This allows the generic late initializations such as cpufreq hooks to be active. Based on out-of-tree patches that need to be introduced in mainline, this introduction allows us to provide the foundation for further SoC specific features as they are developed.

As part of the transition to DT, no board files will be used for OMAP5. The hwmod data is gradually being transitioned away from arch/arm/mach-omap2: IRQ, DMA, and memory map data has been moved to DT. Hopefully the dev_attr and clock role data will be the next step.

Minimal early init - PRCM initialization not yet taken care. Control module is similar (base address, feature register etc.) as that of AM335x, while PRCM base address is different. Instead of adding a new header file for AM43x, PRCM base address is added in AM335x header file as it is similar to it to a large extent.
