Subject: [PATCH] ASoC: tegra: Allow 24bit and 32bit samples
Git-commit: f3ee99087c8ca0ecfdd549ef5a94f557c42d5428
Patch-mainline: v5.5-rc1
References: jsc#SLE-16518
The tegra3 audio can support 24 and 32 bit sample sizes so add the
option to the tegra30_i2s_hw_params to configure the S24_LE or S32_LE
formats when requested.
