Merge tag 'asoc-v5.1' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v5.1
Lots and lots of new drivers so far, a highlight being the MediaTek
BTCVSD which is a driver for a Bluetooth radio chip - the first such
driver we've had upstream. Hopefully we will soon also see a baseband
with an upstream driver!
- Support for only powering up channels that are actively being used.
- Quite a few improvements to simplify the generic card drivers,
especially the merge of the SCU cards into the main generic drivers.
- Lots of fixes for probing on Intel systems, trying to rationalize
things to look more standard from a framework point of view.
- New drivers for Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341,
Google ChromeOS embedded controllers, Ingenic JZ4725B, MediaTek
BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328, Spreadtrum
DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM formatters.
