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

2018-05-23T01:36:26Z

[ 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

2018-05-23T01:36:26Z

[ 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: Fix PM and non-atomic crash in bytcr drivers

2017-05-17T19:08:24Z

[ Upstream commit 6e4cac23c5a648d50b107d1b53e9c4e1120c7943 ] The FE setups of Intel SST bytcr_rt5640 and bytcr_rt5651 drivers carry the ignore_suspend flag, and this prevents the suspend/resume working properly while the stream is running, since SST core code has the check of the running streams and returns -EBUSY. Drop these superfluous flags for fixing the behavior. Also, the bytcr_rt5640 driver lacks of nonatomic flag in some FE definitions, which leads to the kernel Oops at suspend/resume like: BUG: scheduling while atomic: systemd-sleep/3144/0x00000003 Call Trace: dump_stack+0x5c/0x7a __schedule_bug+0x55/0x70 __schedule+0x63c/0x8c0 schedule+0x3d/0x90 schedule_timeout+0x16b/0x320 ? del_timer_sync+0x50/0x50 ? sst_wait_timeout+0xa9/0x170 [snd_intel_sst_core] ? sst_wait_timeout+0xa9/0x170 [snd_intel_sst_core] ? remove_wait_queue+0x60/0x60 ? sst_prepare_and_post_msg+0x275/0x960 [snd_intel_sst_core] ? sst_pause_stream+0x9b/0x110 [snd_intel_sst_core] .... This patch addresses these appropriately, too. Signed-off-by: Takashi Iwai Acked-by: Vinod Koul Signed-off-by: Mark Brown Cc: # v4.1+ Signed-off-by: Sasha Levin

ASoC: Intel: Get correct usage_count value to load firmware

2015-08-17T03:52:17Z

commit 412efa73dcd3bd03c1838c91e094533a95529039 upstream. The usage_count variable was read before it was set to the correct value, due to which the firmware load was failing. Because of this IPC messages sent to the firmware were timing out causing a delay of about 1 second while playing audio from the internal speakers. With this patch the usage_count is read after the function call pm_runtime_get_sync which will increment the usage_count variable and the firmware load is successful and all the IPC messages are processed correctly.
