[PATCH/RFC] ARM: shmobile: rcar-gen2: Correct arch timer frequency on R-Car V2H

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

 



According to the datasheet, the frequency of the ARM architecture timer
on R-Car V2H depends on the frequency of the ZS clock, just like on
R-Car E2.

Against renesas-devel-20160613-v4.7-rc3 with "ARM: shmobile: rcar-gen2:
Obtain extal frequency from DT" applied.

Untested due to lack of hardware.
