[PATCH] RFC: ARM: dts: Proposed Goramo MultiLink device tree

2021-07-28 Thread Linus Walleij
This is an example of how I think the Goramo MultiLink device can be supported in the device tree. It requires writing a new 74hc4094 GPIO driver and moving a bunch of the boardfile code into the HSS driver as it is anyways the only user of this facility. If there are other boards supporting HSS t
