I pointed out last time to other schemas and after changes you should
notice that it is the same as other bindings. Or almost the same. See:
samsung,s6e88a0-ams452ef01
samsung,s6e88a0-ams427ap24
samsung,s6e8aa5x01-ams561ra01

so should be added there - to the last one - instead of having one more
file. On mentioned schematics I did not see the panel, thus the pin
supply does not need to be named VDDI, just because output of the PMIC
is called like that.

Best regards,
Krzysztof
