2013-02-05ARM: mxs: use apbx bus clock to drive the timers on timrotv2Torben Hohn
timer resolution of ~32us is pretty low. v2 has 32bits resolution, so we have quite some headroom, and can use the 24MHz clock. v1 has only 16bits, so we only increase v2. So we just exchange the timrot clock in imx28. On imx23 we have timrotv1 and everything stays the same.

2012-12-24ARM: delete struct sys_timerStephen Warren
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-10-30ARM: mx28: Skip OCOTP FEC MAC setup if in DTMarek Vasut
Currently, the kernel unconditionally adds "local-mac-address" and "mac-address" properties under both FEC ethernet DT nodes in case the update_fec_mac_prop() function is called. These properties are loaded with MAC address compiled from vendors OUI and a per-device NIC saved in OCOTP storage. Some more advanced bootloaders do augment the DT passed to the kernel by these properties already. In such case, it is wrong for kernel to override these values. Adjust the FEC MAC address loading so that in case the DT properties are already present in the DT passed from the bootloader, skip the loading from OCOTP altogether. If the DT properties are not present, load them from OCOTP. Note that the later case will lead to zeroed out MAC address if OCOTP is not programmed. This will lead to FEC not working at all.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM soc multiplatform enablement from Olof Johansson: "This is a pretty significant branch. It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while.

2012-09-03gpio/mxs: adopt irq_domain support for mxs gpio driverShawn Guo
Remove irq_domain_add_legacy call from mach-mxs.c and have the gpio driver adopt irqdomain support, so that we can have the mapping between gpio and irq number available without using virtual_irq_start and MXS_GPIO_IRQ_START.

2012-08-28ARM: mxs: Update DENX M28 machine and dts fileMarek Vasut
Update the mach-mxs machine by removing the enet_clkout(). The new revision of the board doesn't need that. Also, update the DTS file with all the new drivers pulled in the mainline recently, that is, SPI, LRADC, USB.

With all the board files removed, there is no user for those platform device code. Remove them. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

With all board files removed, those core functions used for non-DT boot only can be removed now. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

Since DT kernel provides the equivalent support with those board files, we can remove them now. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Cc: Lothar Waßmann <LW@KARO-electronics.de> Cc: Marek Vasut <marex@denx.de> Cc: Lauri Hintsala <lauri.hintsala@bluegiga.com>
2012-08-17ARM: mxs: use auxdata to pass flexcan_switch function hookShawn Guo
There are some efforts going on to have flexcan_switch function implemented in flexcan driver, so that this platform function hook can be saved for device tree boot. But due to the mx28evk board design oddness that two flexcan transceivers share one switch gpio, we have to come up a separate and generic gpio-switch driver to handle all these gpio switch use cases. Before that happens, we choose to use auxdata to pass flexcan_switch function hook, so that the DT conversion is not blocked there. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2012-08-17ARM: mxs: tx28: reset fec phy for device tree bootShawn Guo
For non-DT boot, function tx28_add_fec0 configures all ENET0 pins into gpio mode for resetting fec phy, and then reconfigures those pins into ENET function after that. For DT boot, all the pin configuration is done by pinctrl subsystem. Ideally, when gpio_request gets called, GPIO subsystem should call pinctrl to configure pins into gpio mode automatically, and have pins freed up from pinctrl subsystem when gpio_free is called. But right now, this cooperation between gpio and pinctrl hasn't been available. As the result, we have to explicitly call pinctrl_get_select and pinctrl_put for device tree boot.

2012-08-17ARM: mach-mxs: Remove board entries in dt_board_compatFabio Estevam
There is no need for adding board related entries into dt_board_compat. Leave only the SoC entry. This way we do not need to patch a C file when adding dt support for a new board. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

Pull arm-soc device tree description updates from Arnd Bergmann: "This branch contains two kinds of updates: Some platforms in the process of getting converted to device tree based booting, and the platform specific patches necessary for that are included here. Other platforms are already converted, so we just need to update the actual device tree source files and the binding documents to add support for new board and new drivers. In the future we will probably separate those into two branches, and in the long run, the plan is to move the device tree source files out of the kernel repository, but that has to wait until we have completed a much larger portion of the binding documents." Fix up trivial conflicts in arch/arm/mach-imx/clk-imx6q.c due to newly added clkdev registers next to a few removed unnecessary ones. * tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (119 commits) ARM: LPC32xx: Add PWM to base dts file ARM: EXYNOS: mark the DMA channel binding for SPI as preliminary ARM: dts: Add nodes for spi controllers for SAMSUNG EXYNOS5 platforms ARM: EXYNOS: Enable platform support for SPI controllers for EXYNOS5 ARM: EXYNOS: Add spi clock support for EXYNOS5 ARM: dts: Add nodes for spi controllers for SAMSUNG EXYNOS4 platforms ARM: EXYNOS: Enable platform support for SPI controllers for EXYNOX4 ARM: EXYNOS: Fix the incorrect hierarchy of spi controller bus clock ARM: ux500: Remove PMU platform registration when booting with DT ARM: ux500: Remove temporary snowball_of_platform_devs enablement structure ARM: ux500: Ensure vendor specific properties have the vendor's identifier pinctrl: pinctrl-nomadik: Append sleepmode property with vendor specific prefixes ARM: ux500: Move rtc-pl031 registration to Device Tree when enabled ARM: ux500: Enable the AB8500 RTC for all DT:ed DB8500 based devices ARM: ux500: Correctly reference IRQs supplied by the AB8500 from Device Tree ARM: ux500: Apply ab8500-debug node do the db8500 DT structure ARM: ux500: Add a ab8500-usb Device Tree node for db8500 based devices ARM: ux500: Add db8500 Device Tree node for misc/ab8500-pwm ARM: ux500: Add db8500 Device Tree node for ab8500-sysctrl ARM: ux500: Enable LED heartbeat functionality on Snowbal via DT ...
