[PATCH v1 1/2] ASoC: tegra: Restore AC97 support
The device-tree of AC97 codecs need to be parsed differently from I2S codecs, plus codec device may need to be created. This was missed by the patch that unified machine drivers into a single driver, fix it. It should restore audio on Toradex Colibri board.

The default card name for Trimslice device should be "tegra-trimslice". It got lost by accident during unification of machine sound drivers, fix it.

Thanks!
[1/2] ASoC: tegra: Restore AC97 support commit: de8fc2b0a3f9930f3cbe801d40758bb1d80b0ad8 [2/2] ASoC: tegra: Set default card name for Trimslice commit: 824edd866a13db7dbb0d8e26d2142f10271b6460
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
