2012-10-15mx5 clocks: Fix get_periph_clk()Benoît Thébaudeau
In the case periph_clk comes from periph_apm_clk, the latter is selected by the CCM.CBCMR.periph_apm_sel mux, which can source the lp_apm clock from its input ♯2. get_periph_clk() returned 0 instead of the lp_apm clock frequency in this case.

2012-10-15mx5 clocks: Fix get_lp_apm()Benoît Thébaudeau
If CCM.CCSR.lp_apm is set, the lp_apm clock is not necessarily 32768 Hz x 1024. In that case: - on i.MX51, this clock comes from the output of the FPM, - on i.MX53, this clock comes from the output of PLL4. This patch fixes the code accordingly.

2012-10-15mx5 clocks: Add and use CCSR definitionsBenoît Thébaudeau
This fixes config_pll_clk(), which used 0x20 instead of 0x200 for PLL4_CLOCK. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>
2012-10-15mx51: Fix USB PHY clocksBenoît Thébaudeau
The i.MX51 has a single USB PHY clock, while the i.MX53 has two. These 3 clocks have different clock gate control bit-fields. The existing code was correct only for i.MX53, so this patch fixes the i.MX51 use case.

2012-10-15mx5: Fix clock gate valuesBenoît Thébaudeau
The clock gate values are 2-bit bit-fields. Hence, setting or clearing only one of these bits like what was done is wrong and can lead to unpredictable behavior depending on the original value of these bit-fields.

2012-10-15mx5 clocks: CleanupBenoît Thébaudeau
Clean up the i.MX5 clock driver: - Use readl() and writel() instead of their __raw_ counterparts. - Use the clr/setbits_le32() family of macros rather than expanding code. - Use accessor macros for bit-fields instead of _MASK and _OFFSET.

2012-10-15tegra20: rework UART GPIO handlingLucas Stach
Rename board provided gpio_config_uart() to gpio_early_init_uart() as it does the same thing as the equally called function provided by the uart-switch code. This allows to simply call this function in early board init whether or not we are building with CONFIG_UART_SWITCH defined. Also provide a weak symbol for this function, to avoid the need to provide this function for boards that don't need any fixup. This patch supersedes the earlier posted "tegra: convert gpio_config_uart to weak symbol".

2012-10-15Tegra20: Move some include files to arch-tegra for sharing with Tegra30Tom Warren
The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

2012-10-15Tegra20: Move some code files to common directories for upcoming Tegra30 ↵Tom Warren
patches. Move files that are going to be common between T20 and T30 into 'tegra-common' subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs and modified for that SoC. The 'common' files should need only minor changes. Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a follow-on patch. Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean. Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-10-15tegra20: add USB ULPI init codeLucas Stach

2012-10-08arm: armv7: omap3: Fix restore sequence in lowlevel_initAlbert ARIBAUD
