This patchset fixes u-boot hang on i.MXRT1050 while setting lcdif in mxsfb
driver. There are 2 gates to be enabled to initialize mxsfb so let's
introduce the missing gate as a clock and rename "per" clock to "pix" clock
since in the other .dts files using *-lcdif "pix" is used.
This patchset add also "disp_axi" clock enabling in mxsfb that should make
able to every i.MX SoC with lcdif using DT. I didn't test it other than
i.MXRT1050 since I don't have the boards. If someone can test it it would
be great. Note that i.MX23/28 should fail using DT instead because they
don't specify any clock-names in their dts.
I've forgotten to specify that this patchset depends on this patchset:
