Subject: [PATCH v6 0/6] clk: Add functions to get optional clocks
Date: Fri, 16 Nov 2018 14:59:31 +0000 [thread overview]
Message-ID: <20181116145937.27660-1-phil.edworthy@renesas.com> (raw)
Quite a few drivers get an optional clock, e.g. a bus clock required to
access peripheral's registers that is always enabled on some devices. This
series adds of_clk_get_by_name_optional(), clk_get_optional() and
devm_clk_get_optional() functions for this purpose.
The functions behave the same as of_clk_get_by_name(), clk_get() and
devm_clk_get() except that they will return NULL instead of -ENOENT. This
allows for simpler error handling in the callers.
*Note*
This changes the return values for of_clk_get_by_name() in some cases, see
[PATCH 1/6] clk: Add of_clk_get_by_name_optional() function.
v6:
- Rework the __of_clk_get_by_name() logic so as to avoid duplicate tests.
- Add doxygen style comment for devm_clk_get_optional() args
- Add clk_get_optional() to archs that don't use the commom clk framework.
