Subject: [PATCH 1/2] clk: tegra30: Add hda clock default rates to clock driver
Date:   Fri, 25 Dec 2020 01:20:25 +0000

Current implementation defaults the hda clocks to clk_m.
This causes hda to run too slow to operate correctly.
Fix this by defaulting to pll_p and setting the frequency to the correct rate.

This matches upstream t124 and downstream t30.
