This initial submission enables only what mainline supports today. Display (DE/TCON/DSI), PWM backlight, audio codec, camera (CSI/VIN) and LRADC keys are deliberately left out, as those blocks are not supported in mainline yet. They will be sent separately. Patches 1 and 2 overlap with Andre's series https://lore.kernel.org/linux-sunxi/20260914210115.28151-1-andre.przywara@arm.com/T/#ma8a2554315eccbccdb15ee7ac212a4d0afb45a5c They are included for compatibility and differ only in the full company name in the description. Touchscreen operation requires firmware extraction from the Android firmware kernel module; the file will be added to a public repository later. The values below were obtained experimentally via evtest: touchscreen-size-x = <1786>; touchscreen-size-y = <1128>; With the values below the touchscreen and display coordinates match: touchscreen-inverted-y; touchscreen-swapped-x-y; U-Boot support requires an LPDDR3 driver for the A523, which will be sent a bit later. A ready-to-use image with working display, audio and touchscreen can be found on the Manjaro forum. Patches will be added as other contributors add their parts. Based on 7.3-rc3.
