* | mx25: Fix decode_pllBenoît Thébaudeau2012-10-15-3/+6
| | | | | | | | | | | | | | | | The MFN bit-field of the PLL registers represents a signed value. See the reference manual. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>
* | mx5/6 clocks: Fix SDHC clocksBenoît Thébaudeau2012-10-15-1/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i.MX5 eSDHC clocks were considered as coming from the IPG clock although they have dedicated clock paths. Also, on i.MX5/6, each SDHC instance has a dedicated clock, so gd->sdhc_clk must be set accordingly. This is good for the case only a single SDHC instance is used (initialization made with fsl_esdhc_mmc_init()). A future patch will fix the multi-instance use case (initialization made directly with fsl_esdhc_initialize()).

* | mx51: Fix I2C clock ID checkBenoît Thébaudeau2012-10-15-1/+5
| | | | | | | | | | | | | | There are only 2 I²C instances on i.MX51, but 3 on i.MX53. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>
* | mx5 clocks: Fix MXC_FEC_CLKBenoît Thébaudeau2012-10-15-3/+2
| | | | | | | | | | | | | | | | | | The FEC clock does not come from PLL1, but from the IPG clock. The previous code was even inconsistent with itself, returning the IPG clock as expected for imx_get_fecclk(), but the PLL1 clock for mxc_get_clock(MXC_FEC_CLK).

* | mx5 clocks: Simplify imx_get_cspiclk()Benoît Thébaudeau2012-10-15-20/+3
| | | | | | | | | | | | | | | | | | The code handling the dividers was duplicated for each possible input clock, and this function can benefit from the newly introduced get_standard_pll_sel_clk() function instead of duplicating this mux handling code.

* | mx5 clocks: Fix get_uart_clk()Benoît Thébaudeau2012-10-15-12/+24
| | | | | | | | | | | | | | | | | | | | | | | | This function returned 66500000 instead of the correct lp_apm clock frequency if the CCM.CSCMR1.uart_clk_sel mux is set to 3. This patch fixes this issue by introducing the get_standard_pll_sel_clk() function that will be used by future patches to handle identical muxes used by many other clocks.

* | mx5 clocks: Fix get_ipg_per_clk()Benoît Thébaudeau2012-10-15-3/+7
| | | | | | | | | | | | | | | | | | | | | | This fixes the "IPG PERCLK" frequency printed by the clocks command. The issue was that get_ipg_per_clk() used periph_clk instead of lp_apm in the case CCM.CBCMR.perclk_lp_apm_sel is set. It also fixes I²C support.

* | mx5 clocks: Fix get_periph_clk()Benoît Thébaudeau2012-10-15-20/+22
| | | | | | | | | | | | | | | | | | | | 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.

* | mx5 clocks: Fix get_lp_apm()Benoît Thébaudeau2012-10-15-1/+38
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* | mx51: Fix USB PHY clocksBenoît Thébaudeau2012-10-15-9/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | mx5: Fix clock gate valuesBenoît Thébaudeau2012-10-15-12/+18
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".

| | | | | | | | | | | | | | | | | | | | | | 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.

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>
