[PATCH v3 0/3] pmdomain: rockchip: fix the probe error and deferral paths

[Arun Iyengar via B4 Relay <devnull+aiyengar1990.gmail.com@kernel.org>]

Fixes for a Rockchip power domain controller probe that fails or defers,
for example on a domain clock that is not available yet. They apply on
top of 1/2 of Yao Zi's series [1], which has to go in first; patch 2
replaces 2/2 of [1]. On the pmdomain next branch, 1/2 of [1] conflicts
with "cycle an optional power-domain reset on power-on" in one line.

Tested with v1 on an Orange Pi 5 (RK3588S), v7.3 based kernel, with a
test device tree that makes the PD_FEC clock appear late: no freed
domain left on gpd_list, no -517 errors, and the controller binds later
with all 26 domains. The v2/v3 changes are build-tested only.

Developed with Claude (Anthropic), which wrote the code and the commit
messages. I reviewed every change.

Changes in v3:
- Split 2/2 into the fix (2/3: deferral, pm_qos error code, callers'
  messages) and a clean-up of the other messages without Fixes tags
  (3/3) (Yao Zi)
- Shorter commit messages and comments (Heiko Stuebner)
- No code change from v2 apart from the comments in 1/3
- Link to v2: https://patch.msgid.link/20261112-pmdomain-rockchip-v2-0-5cd942a23df7@gmail.com

Changes in v2:
- Dropped "pmdomain: rockchip: put only the clocks that were got on
  error" for 1/2 of [1], which fixes the same bug
- 2/2: drop the callers' messages and use dev_err_probe() where the
  errors happen (Sebastian Reichel)
- 2/2: a pm_qos syscon error keeps its own code
- Link to v1: https://patch.msgid.link/20261110-pmdomain-rockchip-v1-0-6b9fa6ebaa86@gmail.com
