[PATCH v2 11/14] drm/i915: move rawclk init to intel_cdclk_init()

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

 



The rawclk initialization is a bit out of place in
intel_device_info_runtime_init(). Move it to intel_cdclk_init(), with a
bit of refactoring on intel_read_rawclk().
