* MX35: Add soc_boot_mode and soc_boot_device to MX35Stefano Babic2012-10-26-0/+69

* mx5: lowlevel_init.S: Fix PLL settings for mx53Fabio Estevam2012-10-17-0/+4
| | | | | | | | | | | | | | | | | | Currently PLL2 is not explicitely configured for mx53 and it runs at 333MHz. Since PLL2 is the parent clock for DDR2, IPU, VPU, we should set it at 400MHz instead. Without doing so, it is not possible to use a 2.6.35 FSL kernel and display HDMI at 1080p because the IPU clock cannot reach the requested frequency. Set PLL2 to 400MHz, so that 1080p can be played and the DDR2 can run at its maximum frequency. Also, setup the other PLL's as done in FSL U-boot and re-arrange the code a little bit to allow easier comparison with the original clock setup from FSL U-boot.

* mx6qsabreauto: Pass the board revision to the kernelFabio Estevam2012-10-16-0/+6
| | | | | | | | | | | The kernel from Freescale expects that the bootloader passes the board revision. Read the board revision and pass it via get_board_rev(). Without passing the board revision the kernel does not operate properly as the initialization of peripherals are different in revA versus revB boards.

* mx35: Fix eSDHC clocksBenoît Thébaudeau2012-10-16-1/+3
| | | | | | | | | | | | | | Each eSDHC instance has a dedicated clock. gd->sdhc_clk must also 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()).

* mx31: Fix PDR0_CSI_PODFBenoît Thébaudeau2012-10-15-2/+4
| | | | | | | | | | The CSI PODF bit-field used by the previous code for the i.MX31 CCM PDR0 register is actually composed of two bit-fields: one pre-divider and one post-divider.

* mx25 clocks: Fix MXC_FEC_CLKBenoît Thébaudeau2012-10-15-1/+1
| | | | | | | | | | mxc_get_clock(MXC_FEC_CLK) should return the IPG clock, not the AHB clock. Also, imx_get_fecclk() was correct but reimplemented the calculation of the IPG clock, so remove the duplicated code.

* mx5/6 clocks: Fix SDHC clocksBenoît Thébaudeau2012-10-15-0/+4
| | | | | | | | | | | | | | | | 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()).

* mx5 clocks: Fix get_lp_apm()Benoît Thébaudeau2012-10-15-0/+15
| | | | | | | | | | | | 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.

* mx5 clocks: Add and use CCSR definitionsBenoît Thébaudeau2012-10-15-0/+23

* mx51: Fix USB PHY clocksBenoît Thébaudeau2012-10-15-1/+2
| | | | | | | | | | | | | | | 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 Thébaudeau2012-10-15-0/+3
| | | | | | | | | 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.

| | | | | | | | | | | Common practice on Tegra 2 boards is to use the pllp_out4 FO to generate the ULPI reference clock.

* Tegra20: Move some include files to arch-tegra for sharing with Tegra30Tom Warren2012-10-15-410/+530
| | | | | | | | | | | 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.

* tegra20: add USB ULPI init codeLucas Stach2012-10-15-5/+24
| | | | | | | | | | | | | This adds the required code to set up a ULPI USB port. It is mostly a port of the Linux ULPI setup code with some tweaks added for more correctness, discovered along the way of debugging this. To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT have to be set in the board configuration file.

| | | | | | | | | | | | | | Kill off ehci-core.h It was used to specify some static controller data. To support more than one controller being active at any time we have to carry the controller data ourselfes. Change the ehci interface accordingly. NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed to do the same thing as other platforms. But the change for now is at least compile clean.
