Ye Li fcd5fac9eb MLK-20781-3 mx7ulp: clock: adjust LCDIF pixclock algorithm
Since LCDIF does not have a dedicated PLL as its source, we have to
find a best frequency closed to the target frequency. The previous
method is finding a closed clock with actual frequency higher than target.
But this causes problem to DSI PHY clock which uses target frequency to
calculate its clock parameters.  When the actaul pixclock is higher,
it may violates the requirement between DSI PHY clock and LCDIF pixclock clock.
clk_byte_freq >= dpi_pclk_freq * DPI_pixel_size / ( 8 * (cfg_num_lanes + 1))

So we'd better selecting a LCDIF clock not exceed the target frequency.

Haibo Chen 1c30a73542 MLK-17586-3 i.MX7ULP: change USDHC clock rate
Change USDHC0 and USDHC1 per clock source from APLL_PFD1,
and set the APll_PFD1 clock rate to 352.8MHz.

Also gate off APll_PFD1/2/3 before boot OS, otherwise set
the clock rate of APll_PFD1/2/3 during OS boot up will triger
some warning message.

Ye Li a590c74185 MLK-17292 mx7ulp: Set A7 core frequency to 500Mhz for B0 chip
The normal target frequency for ULP A7 core is 500Mhz, but now ROM
set the core frequency to 413Mhz. So change it to 500Mhz in u-boot.

Ye Li da29f331ed MLK-14689 mx7ulp: Workaround APLL PFD2 to 345.6Mhz
The GPU uses APLL PFD2 as its clock parent (483.84Mhz) with divider set to 1.
This frequecy is out of ULP A0 spec. The MAX rate for GPU is 350Mhz.
So we simply configure the APLL PFD2 to 345.6Mhz (FRAC=28) to workaround the problem.
The correct fix should let GPU handle the clock rate in kernel.

Ye Li 60d57156df MLK-13929-5 mx7ulp: Update clock and SoC functions for video
Add the clocks functions for enabling LCDIF and DSI clocks.
Also add the arch_preboot_os to disable the video before enter into
the kernel.

Tom Rini 20b9f2eaf5 arm: imx: Rework i.MX specific commands to be excluded from SPL
The "clocks" and "bootaux" commands are only usable in full U-Boot, not
SPL, so do not link them inside of SPL.  Rework a little of the bootaux
related code to make use of __weak and declare parts of it static as
it's local to the file.

Stefano Babic 552a848e4f imx: reorganize IMX code as other SOCs
Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/<SOC>.

This change is also coherent with the structure in kernel.
