NT35596 provides several system interfaces like MIPI/SPI/I2C. Microtech MTF050FHDI-03 is 1080x1920, 4-lane MIPI DSI LCD panel which has inbuilt NT35596 IC chip. NT35596 support several regulators on the chip, among those only 4 regulators like VCI, VDDI/DVDD, AVDD, AVEE are used during power-on sequence. Out of four regulators MTF050FHDI-03 panel do support 3-regulator based power-on sequence, so this patch documented these 3 needful regulators and rest can be add while supporting new panels on the similar chip IC.
