[PATCH v3 1/9] [media] s5p-jpeg: Document sclk-jpeg clock for Exynos3250 SoC

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

 




From: Jacek Anaszewski <j.anaszewski@xxxxxxxxxxx>

JPEG IP on Exynos3250 SoC requires enabling two clock gates
for its operation. This patch documents this requirement.
