Subject: [PATCH v8 0/3] Add of_regulator_get_optional() and Fix MTK Power Domain Driver
Hi folks,
This series is split off from my "DT hardware prober" series [1].
Changes since v7:
- Added stub versions for of_regulator_get_optional() for !CONFIG_OF
and !CONFIG_REGULATOR
- Added new patches for devres version and converting MTK pmdomain
driver
At ELCE, Sebastian told me about his recent work on adding regulator
supply support to the Rockchip power domain driver [2], how the MediaTek
driver has been using the existing devm_regulator_get() API and
reassigning different device nodes to the device doing the lookup, and
how the new of_regulator_get_optional() is the proper fit for this.
Patch 1 adds a new of_regulator_get_optional() function to look up
regulator supplies using device tree nodes.
Patch 2 adds a devres version of the aforementioned function at
Sebastian's request for the two power domain drivers.
Patch 3 converts the MediaTek power domain driver to use function.
Each of the latter two patches depend on the previous one at build time.
Mark, would it be possible for you to put the two regulator patches
on an immutable branch / tag? Otherwise we could have Ulf ack the
pmdomain patch and merge it through your tree. Sebastian was fine
with converting the rockchip pmdomain some time later.
Thanks
ChenYu

Chen-Yu Tsai (3):
regulator: Add of_regulator_get_optional() for pure DT regulator
lookup
regulator: Add devres version of of_regulator_get_optional()
pmdomain: mediatek: Use OF-specific regulator API to get power domain
supply
