| |
Currently the default clock rates for the HDA and HDA2CODEC_2X clocks are both 19.2MHz. However, the default rates for these clocks should actually be 51MHz and 48MHz, respectively. The current clock settings results in a distorted output during audio playback. Correct the default clock rates for these clocks by specifying them in the clock init table for Tegra210.
Cc: stable@vger.kernel.org Signed-off-by: Jon Hunter <jonathanh@nvidia.com> Acked-by: Thierry Reding <treding@nvidia.com> --- Changes since V1: - Updated the changelog and cc'ed stable.
Please note that I have not added a fixes tag because this has always been broken for Tegra210.
