[PATCH v2] drivers: clk: make gpio-gated clock support optional

[PATCH v2] drivers: clk: make gpio-gated clock support optional

[Enrico Weigelt, metux IT consult]

The gpio-gate-clock / gpio-mux-clock driver isn't used much,
just by a few ARM SoCs, so there's no need to always include
it unconditionally.

Thus make it optional, but keep it enabled by default.

changes v2: fixed meanwhile removed '---help---'

[PATCH] (v2) drivers: clk: make gpio-gated clock support optional

[Enrico Weigelt, metux IT consult]

The gpio-gate-clock / gpio-mux-clock driver isn't used much,
just by a few ARM SoCs, so there's no need to always include
it unconditionally.

Thus make it optional, but keep it enabled by default.

fixes v2: added missing dependency on gpiolib

Maybe 'default GPIOLIB'?

Does lowercase work here?

thanks, fixed it in v3.


BTW: just accidentially posted an outdated and broken version again
(some submit helper script was running wild :() - please ignore that.
the valid one is v3 from yesterday. sorry for the noise.
