Merge series "ASoC: SOF: Intel: DMI L1 power optimization for HDaudio platforms" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: This patchset provides an optimization that result in significant power savings on Intel HDAudio platforms using SOF (Sound Open Firmware). We previously prevented the Intel DSP from enabling the DMI_L1 capability to work-around issues with pause on capture streams. It turns out that this also prevented the platform from entering high C states in full-duplex usages such as videoconferencing - a rather basic use case since the start of the pandemic. The support for pause_push/release was already a bit controversial for Intel platforms, in theory platforms should only enable PAUSE if they can resume on the same sample, which is not the case on any Intel platform. With this patchset, when the user enables DMI L1 via a kernel parameter, the PAUSE support is disabled for capture streams. A kernel parameter is far from ideal but it's a placeholder until we have an API to negotiate capabilities between applications and driver, and it's far less confusing than a Kconfig option. Changes since v1: Removal of SPIB support since it may conflict with Takashi's memalloc changes. These SPIB changes will be provided after rebase. Addition of one cleanup for cppcheck warning Move all changes to intel/ directory, no changes in shared code Flipped the logic: the selection of DMI L1 disables PAUSE Pierre-Louis Bossart (4): ASoC: SOF: Intel: Kconfig: clarify DMI L1 option description ASoC: SOF: Intel: hda-stream: remove always true condition ASoC: SOF: Intel: simplify logic for DMI_L1 handling ASoC: SOF: Intel: make DMI L1 selection more robust sound/soc/sof/intel/Kconfig | 10 ---------- sound/soc/sof/intel/hda-pcm.c | 16 ++++++++++++++-- sound/soc/sof/intel/hda-stream.c | 11 +++++------ 3 files changed, 19 insertions(+), 18 deletions(-) -- 2.25.1

Exposing the DMI L1 configuration as a kernel Kconfig option was in hindsight a really bad idea. It led to several errors reported by distributions which selected it by mistake. The Kconfig is now replaced with a kernel parameter. Since DMI L1 entry is incompatible with pause on a capture stream, the latter is disabled when the kernel parameter is set. Experimental results show an increased residency in higher C states and a significant decrease of system power consumption for "work from home" usages such as VoIP calls. Signed-off-by:

When I booted up on a board that had a slightly different codec stuffed on it, I got this message at bootup: rt5682 9-001a: Device with ID register 6749 is not rt5682 That's normal/expected, but what wasn't normal was the splat that I got after: WARNING: CPU: 7 PID: 176 at drivers/regulator/core.c:2151 _regulator_put+0x150/0x158 pc : _regulator_put+0x150/0x158 ...

If the machine driver doesn't call snd_soc_dai_set_sysclk() the SCLK is assumed to be sample_rate * sample_bits * 2 (that is, the rate necessary for a standard I2S frame). But 24-bit samples can be sent in either a 24-bit slot or a 32-bit slot. If the PLL is configured for a 24-bit slot, but a 32-bit slot is used, cs42l42 will be overclocked. Ultimately it is the machine driver's responsibilty to call snd_soc_dai_set_sysclk() if SLK will be different from the standard I2S rate. However, it is convenient to assume 32-bit slots to allow this common case without needing special machine driver support. The machine driver then only has to set SCLK if the slots are 24-bit, but if it fails to do this cs42l42 won't be overclocked. Signed-off-by:

I2S always has two LRCLK phases and both CH1 and CH2 of the RX must be enabled (corresponding to the low and high phases of LRCLK.) The selection of the valid data channels is done by setting the DAC CHA_SEL and CHB_SEL. CHA_SEL is always the first (left) channel, CHB_SEL depends on the number of active channels. Previously for mono ASP CH2 was not enabled, the result was playing mono data would not produce any audio output. Signed-off-by:

The lowest valid SCLK corresponds to 44.1 kHz at 16-bit. Sample rates less than this would produce SCLK below the minimum when using a normal I2S frame. A constraint must be applied to prevent this. The constraint is not applied if the machine driver sets SCLK, to allow setups where the host generates additional bits per LRCLK phase to increase the SCLK frequency. In these cases the machine driver would always have to inform this driver of the actual SCLK, and it must select a legal SCLK. Signed-off-by:

An I2S frame starts on the falling edge of LRCLK so ASP_STP must be 0. At the same time, move other format settings in the same register from cs42l42_pll_config() to cs42l42_set_dai_fmt() where you'd expect to find them, and merge into a single write. Signed-off-by:

Both SCLK and PLL clocks must be running to drive the glitch-free mux behind MCLK_SRC_SEL and complete the switchover. This patch moves the writing of MCLK_SRC_SEL to when the PLL is started and stopped, so that it only transitions while the PLL is running. The unconditional write MCLK_SRC_SEL=0 in cs42l42_mute_stream() is safe because if the PLL is not running MCLK_SRC_SEL is already 0. Signed-off-by:
