The patch

   ASoC: rsnd: add RSND_GEN3 for R-Car Gen3

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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.

Subject: [PATCH] ASoC: rsnd: add RSND_GEN3 for R-Car Gen3

rsnd driver is supporting Gen3. The difference between Gen1 and Gen2
were very big, but, between Gen2 and Gen3 are not so much.
Thus, it is assuming Gen2 and Gen3 have compatible, therefore,
there is no RSND_GEN3 and rsnd_is_gen3() macro.
But in the future, it will need Gen2 and Gen3 different operation,
and for Gen4.
This patch adds missing RSND_GEN3 and rsnd_is_gen3() macro.
