to look at the new patch set (#3).
Change subject: mb/google/kukui: Fix LCD sequence T3 fail issue ......................................................................
mb/google/kukui: Fix LCD sequence T3 fail issue
The T3 that PPVARN_LCD low to LCM_RST_1V8 high is 0.1269ms and it does not meet the LCD specification that the T3 must be larger than 5ms. Because there is a delay between PPVARN_LCD_EN and PPVARN_LCD. An extra 9ms delay should be added on LCM_RST_1V8 in order to meet the specification "ProductSpec_NV105WUM-A51_ V4.3_P2(TLCM).pdf".
BUG=b:172201138 BRANCH=kukui TEST=The LCD sequence T3 is larger than 5ms when power on.
