[PATCH 1/2] ASoC: arizona: Set compressed IRQ to a wake source

[Charles Keepax]

The current code is not setting the compressed IRQ as a wake
source.  Normally this doesn't cause any issues as the CODEC
IRQ is set as a wake source by the jack detection code and the
CODEC only produces a single IRQ line. However if the system
is not using jack detection the compressed audio IRQ should
still function as a wake source, as such directly set the
compressed audio IRQ as a wake source.

[PATCH 2/2] ASoC: wm_adsp: Simplify handling of alg offset and length

[Charles Keepax]

The current code that reads the algorithm list from the DSP is
somewhat unclear, it converts directly from bytes to registers using
a hard coded divide by 2. Most offsets are usually handled in DSP
words within the driver and there is a function specifically for
converting from words to register addresses. So update the handling
to use these. This also removes the assumption that the registers
are 16-bit word addressed, which will no longer be true on some of
our newer parts.

Applied "ASoC: arizona: Set compressed IRQ to a wake source" to the asoc tree

[Mark Brown]

The patch

   ASoC: arizona: Set compressed IRQ to a wake source

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.

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
