X-Git-Tag: baikal/mips/sdk6.1~7028^2
X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=d2c025f22e2aff7b2189812209482406d36c65cd;p=kernel.git

mips: lantiq: add support for clk_get_parent()

Provide a simple implementation of clk_get_parent() in the
lantiq subarch so that callers of it will build without errors.

Fixes this build error:
ERROR: modpost: "clk_get_parent" [drivers/iio/adc/ingenic-adc.ko] undefined!

Fixes: 0d7c54bcdab4 ("MIPS: Lantiq: Add initial support for Lantiq SoCs")
