Hi All,
I have come up with two solutions for fixing this issue.
Please suggest which solution, I should submit.
First solution allows to build the driver for m68k architecture,
whereas the second solution skips it.
Solution 1: Add static inline functions in clk-provider.h

Solution 2: Add dependency to COMMON_CLK
--------------------------------------
config REGULATOR_RAA215300
tristate "Renesas RAA215300 driver"
select REGMAP_I2C
+ depends on COMMON_CLK
depends on I2C
help
Support for the Renesas RAA215300 PMIC.
Cheers,
Biju
