The reason for this series is to remove support for platform data in the ads7846 touchscreen driver, as pdm360ng is the last user of legacy platform data in the kernel for this driver.
This series converts the ADS7845 touchscreen on the PDM360NG board to use Device Tree bindings instead of legacy platform data callbacks: - Move GPIO controller capabilities into mpc5121.dtsi so all MPC5121 boards inherit proper controller definitions, and remove redundant local declarations from ac14xx.dts - Update pdm360ng.dts to use "ti,ads7845" with pendown-gpio and interrupt-parent referencing gpio_pic - Add "ifm,pdm360ng" to mpc512x_generic.c and delete obsolete pdm360ng.c. This change has been discussed in '24i but I just got around to implementing this: https://lore.kernel.org/r/[email protected]/ Note that this should compile but I have not tried this on real hardware.
