AXS15231B display panel (QSPI interface). Combined display+touch controller chip - see
|
|
axs,axs15231b-touch for the touch side, which sits on a separate I2C bus and is modeled as an
|
|
independent devicetree node.

|
description: Optional Tearing-Effect GPIO pin. When set, draw_bitmap waits (best-effort, up

|
to 20ms) for a V-blank pulse on this pin before starting each transfer, to reduce visible

tearing. Omit to skip TE sync entirely.

Custom vendor bring-up sequence, flattened into bytes as a run of

[cmd, data-length, delay-ms, data-length bytes of data...] entries. Omit to use the
|
|
AXS15231B component's own built-in default sequence.

description: >
|
|
Whether this panel needs full-frame-only draws (DISPLAY_CAPABILITY_REQUIRES_FULL_FRAME) -
|
|
a sub-region draw_bitmap() call desyncs this chip's row auto-increment counter, since its
|
|
QSPI command set has no row-address command.
|
|
It's not certain that this is required for all driver implementations, so it's a config option for now.
