2014-05-25sunxi: add sun7i clocks and timer support.Ian Campbell
This patch adds the basic clocks and timer support for the Allwinner A20 (sun7i) processor. This code will not been compiled until the build is hooked up in a later patch. It has been split out to keep the patches manageable. Some of the code here is common to multiple sunxi subarchtectures, hence files are named sun4i which is the earliest similar variant.

2014-05-23ARM: omap: merge GPMC initialization code for all platformpekon gupta
GPMC controller on TI's OMAP SoC is general purpose controller to interface with different types of external devices like; - parallel NOR flash - parallel NAND flash - OneNand flash - SDR RAM - Ethernet Devices like LAN9220 Though GPMC configurations may be different for each platform depending on clock-frequency and external device interfacing with controller. But initialization sequence remains common across all platfoms. Thus this patch merges gpmc_init() scattered in different arch-xx/mem.c files into single omap-common/mem-common.c However, actual platforms specific register config values are still sourced from corresponding platform specific headers like; AM33xx: arch/arm/include/asm/arch-am33xx/mem.h OMAP3: arch/arm/include/asm/arch-omap3/mem.h OMAP4: arch/arm/include/asm/arch-omap4/mem.h OMAP4: arch/arm/include/asm/arch-omap5/mem.h Also, CONFIG_xx passed by board-profile decide config for which set of macros need to be used for initialization CONFIG_NAND: initialize GPMC for NAND device CONFIG_NOR: initialize GPMC for NOR device CONFIG_ONENAND: initialize GPMC for ONENAND device Signed-off-by: Pekon Gupta <pekon@ti.com> [trini: define GPMC_SIZE_256M for omap3] Signed-off-by: Tom Rini <trini@ti.com>

2014-05-13ARM: tegra: use a CPU freq that all SKUs can supportStephen Warren
U-Boot on Tegra30 currently selects a main CPU frequency that cannot be supported at all on some SKUs, and needs higher VDD_CPU/VDD_CORE values on some others. This can result in unreliable operation of the main CPUs. Resolve this by switching to a CPU frequency that can be supported by any SKU. According to the following link, the maximum supported CPU frequency of the slowest Tegra30 SKU is 600MHz: repo http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=summary branch l4t/l4t-r16-r2 path arch/arm/mach-tegra/tegra3_dvfs.c table cpu_dvfs_table[] According to that same table, the minimum VDD_CPU required to operate at that frequency across all SKUs is 1.007V. Given the adjustment resolution of the TPS65911 PMIC that's used on all Tegra30-based boards we support, we'll end up using 1.0125V instead. At that VDD_CPU, tegra3_get_core_floor_mv() in that same file dictates that VDD_CORE must be at least 1.2V on all SKUs. According to tegra_core_speedo_mv() (in tegra3_speedo.c in the same source tree), that voltage is safe for all SKUs. An alternative would be to port much of the code from tegra3_dvfs.c and tegra3_speedo.c in the kernel tree mentioned above. That's more work than I want to take on right now. While all the currently supported boards use the same regulator chip for VDD_CPU, different types of regulators are used for VDD_CORE. Hence, we add some small conditional code to select how VDD_CORE is programmed. If this becomes more complex in the future as new boards are added, or we end up adding code to detect the SoC SKU and dynamically determine the allowed frequency and required voltages, we should probably make this a runtime call into a function provided by the board file and/or relevant PMIC driver.

2014-05-13S5P: Exynos: Add GPIO pin numbering and rename definitionsAkshay Saraswat
This patch includes following changes : * Adds gpio pin numbering support for EXYNOS SOCs. To have consistent 0..n-1 GPIO numbering the banks are divided into different parts where ever they have holes in them. * Rename GPIO definitions from GPIO_... to S5P_GPIO_... These changes were done to enable cmd_gpio for EXYNOS and cmd_gpio has GPIO_INPUT same as s5p_gpio driver and hence getting a error during compilation. * Adds support for name to gpio conversion in s5p_gpio to enable gpio command EXYNOS SoCs. Function has been added to asm/gpio.h to decode the input gpio name to gpio number.
