Commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared
and enabled clocks") provides a new helper function for prepared and
enabled clocks when a driver keeps a clock prepared (or enabled) during
the whole lifetime of the driver. So where drivers get clocks and enable
them immediately, it can be combined into a single function
devm_clk_get_*(). Moreover, the unprepare and disable function
has been registered to devm_clk_state, and before devm_clk_state is
released, the clocks will be unprepareed and disable, so it is unnecessary
to unprepare and disable clock explicitly when remove drivers or in the
error handling path.
Change log:
v2:
- Modify the format of the reference commit, use "since" instead of
"after".
- Drop the helper functions mtk_nfc_enable_clk() and
mtk_nfc_disable_clk(), because both of them now have a single user.
- Add a new patch, replace devm_clk_get_optional() +
clk_prepare_enable() with devm_clk_get_optional_enabled().
