Subject: [PATCH V3 00/20] OPP: Add new configuration interface: dev_pm_opp_set_config()
Hello,
We have too many configuration specific APIs currently, six of them already,
like dev_pm_opp_set_regulators(). This makes it complex/messy for both the OPP
core and its users to manage. There is also code redundancy in these APIs, in
the way they add/manage the OPP table specific stuff.
This patch series is an attempt to simplify these interfaces by adding a new
interface, dev_pm_opp_set_config(), which is now used by all the existing ones.
This series also migrates few users to the new API, where multiple
configurations were required and rest are updated for API interface changes.
This is pushed here:
git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git opp/linux-next
This was earlier tested by various folks, I have tested it again on hikey board,
it will get further tested on linux-next in the coming days. Build test is
already done by Linaro's bot for enough platform though.
The entire patchset shall get merged via the OPP tree in 5.20-rc1, please do not
merge individual patches.
V2->V3:
- Merged two patchsets:
[PATCH V2 00/30] OPP: Add new configuration interface: dev_pm_opp_set_config()
[PATCH V2 0/5] OPP: Replace custom set_opp() with config_regulators()
- The existing APIs aren't removed anymore, but are made to use the new core API
to set various configurations (Greg KH).
- clk-names and regulator-names are NULL terminated arrays now (Greg KH).
- New interface added: dev_pm_opp_set_config_regulators().
V1->V2:
- dev_pm_opp_set_config() doesn't return the OPP table anymore, but a token
allocated with xa_alloc(). The same needs to be passed to clear-config API.
- Updated all users according to that as well.
- The clk_names interface is updated to allow multiple clocks.
- Converted few // comments to /* */.
- Added tags by few people.
- Dropped the last patch to rearrange stuff, not required anymore.
Thanks.
