Limited information is available online however the panel timing values (below) have been obtained from the vendor BSP. The panel appears to integrate a NV3052C LCD driver (or clone). Available devices address it in SPI/RGB mode, with the timing signals generated from the device SoC (in testing hardware an Allwinner H700) and passed through. Add a panel definition and display mode to the existing NV3502C driver. It was assumed during bringup that the initialisation sequence was the same as the existing Fascontek FS035VG158 panel, proved working during experimentation. However subsequent dumping of the init sequence with a logic analyser confirms one small change to VCOM_ADJ3 from 0x4a to 0x44, therefore a separate set of registers is also added.
