Subject: [PATCH v2 0/4] drm/panel: Add Novatek NT35596 panel

This is v2 series for Novatek NT35596 panel driver. here is previous
series set[2]

Since there is no proper programming guide for NT35596 IC, the driver 
init sequence is referenced from [1] but analyzed based on datasheet.

NT35596 support several regulators on the chip, among those ony 4
regulators like VCI, VDDI/DVDD, AVDD, AVEE are used during power-on
sequence. Right now driver added code for 3-regulator based power-on
sequence since MTF050FHDI-03 panel support. This power-on sequence may
be moved to panel_desc in future, if there is any new panel would come
up with other type of sequence.

Changes for v2:
- control enable/disable calls using enable, prepare flags
- comment on delays
- move 120ms delay on power-on since it is part of power-on sequence
- fix driver name as novatek-nt35596

Any inputs?
