Subject: [PATCHv4 0/6] Add initial genpd support for omap PRM driver

Hi all,

Here's v4 set of patches to add genpd support to the PRM (Power and Reset
Module) driver.

Initially we just add one hardware accelerator power domain for sgx,
and one interconnect instance for l4_abe. The rest of the SoC specific
domain data is probably best added one SoC at a time based on generated
data.

Regards,

Tony

Changes since v3:
- Drop the unnecessary __maybe_unused as that's no longer needed

Changes since v2:

- Update binding to clarify a single power domain provider

- Unwrap generic domain configrations for __maybe_unused

Changes since v1:

- Dropped clocks from the binding and prm driver as there's no need
  for them as pointed out by Tero

- Add checking for domain transition bit in pwrstst register as
  pointed out by Tero

- Add omap_prm_domain_show_state() for CONFIG_DEBUG
