[PATCH 02/37] ARM: dts: r8a7743: Add audio clocks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Biju Das <biju.das@xxxxxxxxxxxxxx>

Describe the external audio clocks required by the sound driver.
Boards that provide audio clocks need to override the clock frequencies.
