[PATCH v2 0/2] ASoC: tegra: Add Tegra238 sound card support

[Sheetal .]

From: sheetal <sheetal@nvidia.com>

Add Tegra238 sound card support in the Tegra audio graph card driver,
as Tegra238 requires different PLLA and PLLA_OUT0 clock rates compared
to other Tegra platforms.

Changes in v2:
- Drop SPDX-FileCopyrightText year update from patch 2/2

[PATCH v2 1/2] ASoC: dt-bindings: tegra: Add compatible for Tegra238 sound card

[Sheetal .]

From: Sheetal <sheetal@nvidia.com>

Tegra238 requires different PLLA and PLLA_OUT0 clock rates compared to
other Tegra platforms. Add Tegra238 compatible string to the APE
tegra-audio-graph-card bindings.

[PATCH v2 2/2] ASoC: tegra: Add support for Tegra238 soundcard

[Sheetal .]

From: Sheetal <sheetal@nvidia.com>

Tegra238 platforms use different clock rates for plla and
plla_out0 clocks. Add Tegra238 support in the Tegra
sound card driver to apply specific clock configurations.

[2/2] ASoC: tegra: Add support for Tegra238 soundcard
      commit: 1bc17c67194716f53037685b7059a22cc1a911b2

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
