ASoC: Intel: sst: Fix the return value of 'sst_send_byte_stream_mrfld()'

2018-04-12T10:31:08Z

[ Upstream commit eaadb1caa966a91128297b754e90b7c92b350a00 ] In some error handling paths, an error code is assiegned to 'ret'. However, the function always return 0. Fix it and return the error code if such an error paths is taken.

ASoC: Intel: cht_bsw_rt5645: Analog Mic support

2018-04-12T10:31:05Z

[ Upstream commit b70b309950418437bbd2a30afd169c4f09dee3e5 ] Various Cherry Trail boards with a rt5645 codec have an analog mic connected to IN2P + IN2N. The mic on this boards also needs micbias to be enabled, on some boards micbias1 is used and on others micbias2, so we enable both. This commit adds a new "Int Analog Mic" DAPM widget for this, so that we do not end up enabling micbias on boards with a digital mic which uses the already present "Int Mic" widget. Some existing UCM files already refer to "Int Mic" for their "Internal Analog Microphones" SectionDevice, but these don't work anyways since they enable the RECMIX BST1 Switch instead of the BST2 switch.

ASoC: Intel: Skylake: Disable clock gating during firmware and library download

2018-04-12T10:31:05Z

[ Upstream commit d5cc0a1fcbb5ddbef9fdd4c4a978da3254ddbf37 ] During firmware and library download, sometimes it is observed that firmware and library download is timed-out resulting into probe failure. This patch disables dynamic clock gating while firmware and library download.

ALSA: pcm: Use dma_bytes as size parameter in dma_mmap_coherent()

2018-04-08T12:27:33Z

commit 9066ae7ff5d89c0b5daa271e2d573540097a94fa upstream. When trying to use the driver (e.g. aplay *.wav), the 4MiB DMA buffer will get mmapp'ed in 16KiB chunks. But this fails with the 2nd 16KiB area, as the page offset is outside of the VMA range (size), which is currently used as size parameter in snd_pcm_lib_default_mmap(). By using the DMA buffer size (dma_bytes) instead, the complete DMA buffer can be mmapp'ed and the issue is fixed. This issue was detected on an ARM platform (TI AM57xx) using the RME HDSP MADI PCIe soundcard.

ALSA: hda/realtek - Always immediately update mute LED with pin VREF

2018-03-28T16:22:54Z

commit e40bdb03d3cd7da66bd0bc1e40cbcfb49351265c upstream. Some HP laptops have a mute mute LED controlled by a pin VREF. The Realtek codec driver updates the VREF via vmaster hook by calling snd_hda_set_pin_ctl_cache(). This works fine as long as the driver is running in a normal mode. However, when the VREF change happens during the codec being in runtime PM suspend, the regmap access will skip and postpone the actual register change. This ends up with the unchanged LED status until the next runtime PM resume even if you change the Master mute switch. (Interestingly, the machine keeps the LED status even after the codec goes into D3 -- but it's another story.) For improving this usability, let the driver temporarily powering up / down only during the pin VREF change. This can be achieved easily by wrapping the call with snd_hda_power_up_pm() / *_down_pm().

ALSA: hda - Force polling mode on CFL for fixing codec communication

2018-03-28T16:22:53Z

commit a8d7bde23e7130686b76624b099f3e22dd38aef7 upstream. We've observed too long probe time with Coffee Lake (CFL) machines, and the likely cause is some communication problem between the HD-audio controller and the codec chips. While the controller expects an IRQ wakeup for each codec response, it seems sometimes missing, and it takes one second for the controller driver to time out and read the response in the polling mode. Although we aren't sure about the real culprit yet, in this patch, we put a workaround by forcing the polling mode as default for CFL machines; the polling mode itself isn't too heavy, and much better than other workarounds initially suggested (e.g. disabling power-save), at least.
