Remove legacy binding egalax-ts.txt file. And add compatible string eeti,egalax_ts and wakeup-gpios to eeti,exc3000.yaml. "eeti,egalax_ts" is general compatible string, which is not preferred. But it is compatible with old devices (older than 10 years) and existing driver in drivers/input/touchscreen/egalax_ts.c. Allow address 0x4 for eeti,egalax_ts. Don't require touchscreen-size-x(y) for eeti,egalax_ts. Keep the same restriction for existing compatible string. Fix below DTB_CHECKS warnings: arch/arm/boot/dts/nxp/imx/imx6dl-gw52xx.dtb: /soc/bus@2100000/i2c@21a8000/egalax_ts@4: failed to match any schema with compatible: ['eeti,egalax_ts'] Signed-off-by: Frank Li <Frank.Li@nxp.com> Reviewed-by: Rob Herring (Arm) <robh@kernel.org> Link: https://lore.kernel.org/r/20250904171543.517650-1-Frank.Li@nxp.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
