Subject: [PATCH V2 00/30] 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 single
interface, dev_pm_opp_set_config(), which replaces all the existing ones. This
series also migrates the users to the new API.
The first two patches help get the API in place, followed by patches to migrate
the end users. Once all the users are migrated, the last few patches remove the
now unused interfaces.
This is pushed here:
git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git opp/linux-next
This is already tested by various folks now.
The entire patchset shall get merged via the OPP tree in 5.20-rc1, please do not
merge individual patches.
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.
