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.

2014-04-17ARM: tegra: pack pinmux data tables tighterStephen Warren
Use smaller fields in the Tegra pinmux structures in order to pack the data tables into a smaller space. This saves around 1-3KB for the SPL and around 3-8KB for the main build of U-Boot, depending on the board, which SoC it uses, and how many pinmux table entries there are. In order to pack PMUX_FUNC_* into a smaller space, don't hard-code the values of PMUX_FUNC_RSVD* to values which require 16 bits to store them, but instead let their values be assigned automatically, so they end up fitting into 8 bits.

2014-04-17ARM: tegra: pinctrl: remove duplicationStephen Warren
Much of arch/arm/cpu/tegra*-common/pinmux.c is identical. Remove the duplication by creating pinmux-common.c for all the identical code. This leaves: * arch/arm/include/asm/arch-tegra*/pinmux.h defining only the names of the various pins/pin groups, drive groups, and mux functions. * arch/arm/cpu/tegra*-common/pinmux.c containing only the lookup table stating which pin groups support which mux functions. The code in pinmux-common.c is semantically identical to that in the various original pinmux.c, but had some consistency and cleanup fixes applied during migration. I removed the definition of struct pmux_tri_ctlr, since this is different between SoCs (especially Tegra20 vs all others), and it's much simpler to deal with this via the new REG/MUX_REG/... defines. spl.c, warmboot.c, and warmboot_avp.c needed updates due to this, since they previously hijacked this struct to encode the location of some non-pinmux registers. Now, that code simply calculates these register addresses directly using simple and obvious math. I like this method better irrespective of the pinmux code cleanup anyway.

2014-04-17ARM: tegra: use apb_misc.h in more placesStephen Warren
Tegra's "APB misc" register region contains various miscellaneous registers and the Tegra pinmux registers. Some code that touches the misc registers currently uses struct pmux_tri_ctlr, which is intended to be a definition of pinmux registers, rather than struct apb_misc_pp_ctrl, which is intended to be a definition of the miscellaneous registers. Convert all such code to use struct apb_misc_pp_ctrl, since struct pmux_tri_ctlr goes away in the next patch. This requires adding a missing field definition to struct apb_misc_pp_ctrl, and moving the header into a more common location.
