This way, U-Boot can operate the i.MX8M power domains without depending on anything else. This is losely based on Linux GPCv2 driver. The GPU, VPU, MIPI power domains are not supported to save space, since they are not useful in the bootloader. The only domains kept are ones for HSIO, PCIe, USB.

2022-02-15power: zynqmp: Add power domain driver for ZynqMPMichal Simek
Driver should be enabled by CONFIG_POWER_DOMAIN=y and CONFIG_ZYNQMP_POWER_DOMAIN=y. Power domain driver doesn't have own DT node but it uses zynqmp firmware DT node that's why there is a need to bind driver when firmware node is found. Driver itself is simple. It is sending pmufw config object overlay for enabling access to device which is done in ...domain_request(). In ...domain_on() capabilities are passed and node is requested. This should be bare minimum of required to get power domain driver working.

Add support command for debugging K3 power domains. This is useful with the HSM rearch setup, where power domains are directly controlled by SPL instead of going through the TI SCI layer. The debugging support is only available in the u-boot codebase though, so the raw register access power domain layer must be enabled on u-boot side for this to work. By default, u-boot side uses the TI SCI layer, and R5 SPL only uses the direct access methods.
