From: Thierry Reding <treding@xxxxxxxxxx>
pll_a_out0 and the I2S clocks are already configured to default to rates
corresponding to a 44.1 kHz sampling rate, but the pll_a configuration
was set to a default that is not listed in the frequency table, which
caused the PLL code to compute an invalid configuration. As a result of
this invalid configuration, Jetson TK1 fails to resume from suspend.
This used to get papered over because the ASoC driver would force audio
clocks to a 44.1 kHz configuration on boot. However, that's not really
necessary and was hence removed in commit ff5d18cb04f4 ("ASoC: tegra:
Enable audio mclk during tegra_asoc_utils_init()").
Fix the initial rate for pll_a so that it matches the 44.1 kHz entry in
the pll_a frequency table.
Fixes: ff5d18cb04f4 ("ASoC: tegra: Enable audio mclk during tegra_asoc_utils_init()")

Mike, Stephen,
this fixes a regression in v5.7, so it'd be great if you could queue it
up in your fixes branch.
Thanks,
Thierry
