On this board, clocks, power-domains, and resets must be accessed only through SCMI firmware. The series is a bit special, in that most patches are not meant to be applied upstream yet: 1. The first patch, targeting the GPIO tree, restores the abily to use the R-Car GPIO driver on a system that does not have pin control support yet (pin control is not yet supported by SCMI on Ironhide), 2. The second patch, targeting a shared DT bindings branch, adds GPIO clock definitions, 3. The third patch, targeting renesas-devel, adds GPIO device nodes to the R-Car X5H .dtsi file, 4. The remaining patches are marked RFC or DNI; the latter depend on code or DTS that is not yet upstream. More detail can be found in the individual patches. This has been tested on Ironhide using GP05_15..GP05_20 (exposed on the PWM connector), with and without SCMI. Thanks for your comments!
