This patchset add support for LCDIF on i.MXRT1050 evk. This requires
PLL5 to be setup, mxsfb needs to use display_timing to retrieve if Lcd
has inverted PIXCLOCK from dts.
With this patchset applied we temporary loose DCache support until it will
get implemented, since a function in mxsfb.c is needed for setting cache
behaviour. Anyway this way Lcd will show the console same way as serial
does.
Also I've moved private sunxi_ctfb_mode_to_display_timing() to videomodes
since I need it for mxfsb.c too, then having a unified function to convert
from ctfb_mode to display_timing.
Changes:
V1->V2:
* moved hard-coded LCDIF's parent clock from clk-imxrt1050.c to imxrt1050-evk.dts
* reworded some commit log
V2->V3:
* added comment to describe what is a ctfb in videomodes
