Hi, chained to this message is a driver for CH7033 along with device tree binding docs. I'm hoping that it could perhaps make it into 5.7. Please take a look. The only change compared to the previous submission [1] is the fix in the DT bindings example discovered by the validation tool. [1] https://lore.kernel.org/lkml/20200307190800.142658-1-lkundrak@xxxxx/ Tested to work well on MMP3-based Dell Wyse 3020. There's no datasheet or programming manual available.
