[alsa-devel] [PATCH 0/8] ASoC: Intel: Skylake: Add Broxton DSP support
Broxton DSP is similar to Skylake with similar DSP capabilities but differs in a few subtle ways. It doesn't have Code Loader DMA and use HDA DMA. The DSP power up/down routines are also bit different in the two platforms. Also the FW needs to be downloaded only once and not on every power sequence as it is cached by DSP in protected memory region.
All these changes for new DSP ops are abstracted in a new BXTN-dsp ops file.
This patch series starts with moving code around to prepare for new code and also fix whitespace issue in existing code. Since we have different loader ops we move Skylake ones to newly defined ops. Then we add device IDs and lastly the broxton ops.

The patch
ASoC: Intel: Skylake: Move Skylake dsp ops & loader ops
has been applied to the asoc tree at
git://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

From: Jeeja KP jeeja.kp@intel.com Date: Fri, 11 Mar 2016 10:12:53 +0530 Subject: [PATCH] ASoC: Intel: Skylake: Move Skylake dsp ops & loader ops
The code loading for Skylake and other platforms is different, so add a dsp_ops and a loader_ops which can be defined for each platform.
Move the dsp init, cleanup and loader ops (alloc and free dma) to these ops

Broxton DSP is mostly similar to Skylake one but with subtle differences like no Code Load DMA and uses HDA DMA for code loading, DSP D0 and D3 sequences are different.
These changes are comprehended by adding different DSP power up and down handlers, and new loader ops and also adding prepare and trigger which HDA DSP DMA requires

The patch
ASoC: Intel: Bxtn: Add Broxton DSP support
has been applied to the asoc tree at
git://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

From: Jeeja KP jeeja.kp@intel.com Date: Fri, 11 Mar 2016 10:12:56 +0530 Subject: [PATCH] ASoC: Intel: Bxtn: Add Broxton DSP support
Broxton DSP is mostly similar to Skylake one but with subtle differences like no Code Load DMA and uses HDA DMA for code loading, DSP D0 and D3 sequences are different.
These changes are comprehended by adding different DSP power up and down handlers, and new loader ops and also adding prepare and trigger which HDA DSP DMA requires
