Subject: [PATCH AUTOSEL 4.19 121/167] clk: tegra210: Fix default rates for HDA clocks
Date: Tue,  3 Sep 2019 12:24:33 -0400
Message-ID: <20190903162519.7136-121-sashal@kernel.org> (raw)
In-Reply-To: <20190903162519.7136-1-sashal@kernel.org>

From: Jon Hunter <jonathanh@nvidia.com>

[ Upstream commit 9caec6620f25b6d15646bbdb93062c872ba3b56f ]

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.
