Hello, This series adds two IRQ muxes for the Realtek RTD1295 SoC. Based on the reset controller series. There being no public source code for RTD1295, the implementation is based on register offsets seen in the DT, split up into two separate nodes. A workaround for hanging timer initialization was taken from QNAP's rtk119x GPL code dump and is not yet fully understood; that code also contains a quirk for i2c3 in the iso mux that is not yet verified to be needed on RTD1295, for lack of i2c driver, assuming a linear intr_status/intr_en mapping for now. My convention here is to use a compatible string for the model that I've tested (RTD1295) but a file name of rtd119x to indicate its RTD1195 heritage. More experimental patches at: https://github.com/afaerber/linux/commits/rtd1295-next Have a lot of fun!
