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.
