Hello, this is another try to convince the relevant people that devm_clk_get_enabled() is a nice idea. Compared to v7 (back in May 2021) this series is rebased to v5.17-rc8 and converts quite some drivers that open code devm_clk_get_enabled() up to now (patches #3 - #11). A concern about devm_clk_get_enabled() in v7 was that it helps people to be lazy and I agree that in some situations when devm_clk_get_enabled() is used it would be more efficient and sensible to care to only enable the clk when really needed. On the other hand, the function is right for some users, e.g. the watchdog drivers. For the others it's not so simple to judge. Given that there are a lot of drivers that are lazy even if doing so is some effort (i.e. calling clk_prepare_enable() and devm_add_action()) convinces me, that introducing the function family is sensible. (And if you want to work on these drivers, grepping for devm_clk_get_enabled gives you a few candidates once the series is in :-) Otherwise looking at the diffstat of this series: 48 files changed, 257 insertions(+), 851 deletions(-) is quite convincing. Just the first two patches (which introduce the new functions) account for 2 files changed, 169 insertions(+), 17 deletions(-) . A rough third of the added lines is documentation. The rest is driver updates which then has: 46 files changed, 88 insertions(+), 834 deletions(-) which makes a really nice cleanup. The series is build-tested on arm64, m68k, powerpc, riscv, s390, sparc64 and x86_64 using an allmodconfig.
