2012-09-14ARM: tegra: remove board (but not DT) support for TrimSliceStephen Warren
TrimSlice can be booted using device tree with equal functionality as when booted using a board file. Remove the board file since it's no longer needed. One special-case is still left in board-dt-tegra20.c, since the Tegra PCIe driver doesn't support device tree yet. This logic is now enabled by CONFIG_TEGRA_PCI rather than via CONFIG_MACH_TRIMSLICE. The extra cases where it's enabled (.configs which did not enable TrimSlice support) shouldn't impact much since the amount of code is tiny. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-09-14ARM: move all dtb targets out of Makefile.bootRob Herring
In preparation to support multi-platform kernels, move all the dtb targets out of the mach Makefile.boot and into the arch/arm/boot/dts/Makefile which is closer to the sources. DTBs are only built when CONFIG_OF is enabled and now use top level CONFIG_ARCH_xxx instead of chip or board specific config options.

2012-09-14ARM: make mach/gpio.h headers optionalRob Herring
Most platforms don't need mach/gpio.h and it prevents multi-platform kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX or have lots of implicit includes pulled in by mach/gpio.h. at91 and omap have gpio clean-up pending and can drop CONFIG_NEED_MACH_GPIO_H once that is in.

It has also learned to work as USB2 and USB3 phys so we can use it on USB3 controllers. Together with those two changes to nop xceiv, we're adding basic PHY support to dwc3 driver, this is to allow platforms which actually have a SW-controllable PHY talk to them through dwc3 driver. We're adding a new phy driver for the OMAP architecture. This driver is for the PHY found in OMAP4 SoCs, and a new phy driver for the marvell architecture. An extra phy driver - for Tegra SoCs - is now moving from arch/arm/mach-tegra* to drivers/usb/phy. Also here, there's the creation of <linux/usb/phy.h> which should be used from now on for PHY drivers, even those which don't support OTG.
2012-09-11ARM: tegra: cpu-tegra: explicitly manage re-parentingStephen Warren
When changing a PLL's rate, it must have no active children. The CPU clock cannot be stopped, and CPU clock's divider is not used. The old clock driver used to handle this by internally reparenting the CPU clock onto a different PLL when changing the CPU clock rate. However, the new common-clock based clock driver does not do this, and probably cannot do this due to the locking issues it would cause. To solve this, have the Tegra cpufreq driver explicitly perform the reparenting operations itself. This is probably reasonable anyway, since such reparenting is somewhat a matter of policy (e.g. which alternate clock source to use, whether to leave the CPU clock a child of the alternate clock source if it's running at the desired rate), and hence is something more appropriate for the cpufreq driver than the core clock driver anyway.

2012-09-06ARM: tegra: Port tegra to generic clock frameworkPrashant Gaikwad
This patch converts tegra clock code to generic clock framework in following way: - Implement clk_ops as required by generic clk framework. (tegraXX_clocks.c) - Use platform specific struct clk_tegra in clk_ops implementation instead of struct clk. - Initialize all clock data statically. (tegraXX_clocks_data.c) Legacy framework did not have recalc_rate and is_enabled functions. Implemented these functions. Removed init function. It's functionality is splitted into recalc_rate and is_enabled. Static initialization is used since slab is not up in .init_early and clock is needed to be initialized before clockevent/clocksource initialization. Macros redefined for clk_tegra. Also, single struct clk_tegra is used for all type of clocks (PLL, peripheral etc.). This is to move quickly to generic common clock framework so that other dependent features will not be blocked (such as DT binding). Enabling COMMON_CLOCK config moved to ARCH_TEGRA since it is enabled for both Tegra20 and Tegra30.

2012-09-06ARM: tegra: fix U16 divider range checkStephen Warren
A U16 divider can divide a clock by 1..64K. However, the range-check in clk_div16_get_divider() limited the range to 1..256. Fix this. NVIDIA's downstream kernels already have the fixed range-check. In practice this is a problem on Whistler's I2C bus, which uses a bus clock rate of 100KHz (rather than the more common 400KHz on Tegra boards), which requires a HW module clock of 8*100KHz. The parent clock is 216MHz, leading to a desired divider of 270. Prior to conversion to the common clock framework, this range error was somehow ignored/irrelevant and caused no problems. However, the common clock framework evidently has more rigorous error-checking, so this failure causes the I2C bus to fail to operate correctly. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-09-06ARM: tegra: turn on UART A clock at bootStephen Warren
Some boards use UART D for the main serial console, and some use UART A. UART D's clock is listed in board-dt-tegra20.c's clock table, whereas UART A's clock is not. This causes the clock code to think UART A's clock is unsed. The common clock framework turns off unused clocks at boot time. This makes the kernel appear to hang. Add UART A's clock into the clock table to prevent this. Eventually, this requirement should be handled by the UART driver, and/or properties in a board-specific device tree file.

Rob Herring explains: The PCI i/o reserved area has a dummy physical address of 0 and needs to be skipped by ioremap searches. So we don't set VM_ARM_STATIC_MAPPING to prevent matches by ioremap. The vm_struct settings don't really matter when we do the real mapping of the i/o space.

2012-08-09ARM: tegra: more regulator fixes for HarmonyStephen Warren
Commit 3d55c29 "ARM: tegra: harmony: add regulator supply name and its input supply" was supposed to fix all the problems with regulators on Harmony. However, it appears that I only tested it when booting using board files, not when booting using device tree. This change fixes two problems with regulators when booting using device tree: 1) That patch only created the vdd_sys regulator when booting using a board file. Since this is the root of the whole regulator tree, this caused no regulators to successfully initialize when booting using device tree. The registration of vdd_sys is moved to fix this. 2) When booting use DT, the regulator core sets has_full_constraints, which in turn causes the core to turn off any regulators not marked as always on. Some of the affected regulators are required for basic system operation. To solve this, add always on constraints to all relevant regulators. This doesn't affect booting using a board file since nothing sets has_full_constraints in that case. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Pull PWM subsystem from Thierry Reding: "The new PWM subsystem aims at collecting all implementations of the legacy PWM API and to eventually replace it completely. The subsystem has been in development for over half a year now and many drivers have already been converted. It has been in linux-next for a couple of weeks and there have been no major issues so I think it is ready for inclusion in your tree." Arnd Bergmann <arnd@arndb.de>: "Very much Ack on the new subsystem. It uses the interface declarations as the previously separate pwm drivers, so nothing changes for now in the drivers using it, although it enables us to change those more easily in the future if we want to. This work is also one of the missing pieces that are required to eventually build ARM kernels for multiple platforms, which is currently prohibited (amongs other things) by the fact that you cannot have more than one driver exporting the pwm functions."

2012-07-24ARM: tegra: harmony: add regulator supply name and its input supplyLaxman Dewangan
Name the regulator as per board schematics and adds its supply name info in regulator data. Add the always on fixed regulator to refer the battery supply. Use this fixed regulator for input supply of some of PMIC regulator This patch was originally part of a 2-patch series. Patch 2 got applied to the regulator tree as 7c7fac3 "regulator: tps6586x: add support for input supply" without this patch. This broke regulator support on Harmony.
