Name: vc4-kms-dsi-huadi-480x480
Info: Huadi HD40007C30-V5 two-lane DSI panel on Raspberry Pi 5, using
the externally powered Adafruit 30-pin DSI adapter Rev B.
Requires vc4-kms-v3d. Connect to CAM/DISP1 by default.
Touch defaults to I2C polling with APX803 power-on reset; no extra
GPIO wiring is required. Optional TP_INT wiring enables interrupts.
For host-controlled reset, wire both TP_RESET and TP_INT and set
touch_reset and touch_interrupt. Reset uses open-drain operation.
Load: dtoverlay=vc4-kms-dsi-huadi-480x480,<param>=<val>
Params: dsi0 Use CAM/DISP0 instead
notouch Disable the touch controller
touch_reset Optional touch reset GPIO (unset by default)
touch_interrupt Optional touch interrupt GPIO (unset by default)
touch_inverted_x Invert the touch X axis
touch_inverted_y Invert the touch Y axis
touch_swapped_xy Swap the touch X and Y axes
