This adds a new mode WM8904_CLK_AUTO which automatically enables the FLL if a frequency different than the MCLK is set. These additions make the codec work with the simple-card driver in general and especially in systems where the MCLK doesn't match the required clock.

On KBL platform, the microphone is attached to external codec(rt5514) instead of PCH. However, TDM slot between PCH and codec is 16 bits only. In order to avoid setting wrong format, we should add a constraint to force to use 16 bits format forever.

Due to limitations of the clocking configuration, we have no way of scheduling our hibernation before the bdw dsp hibernates. This causes issues when the system suspends with an open stream. We need userspace to toggle the kcontrol before we are suspended so that any writes on suspend are not lost and we don't corrupt the regmap.

The irq is disabled at suspend to avoid running the threaded irq handler after the codec has been powered off. At resume, codec irq is re-enabled and the interrupt status register is checked to see if headphone has been pluggnd/unplugged while the device is suspended. There is still a chance that the headphone gets enabled or disabled after the codec is suspended. disable_irq syncs the threaded irq handler, but soc-jack's threaded irq handler schedules a delayed work to poll gpios (for debounce). This is still OK. The codec won't be powered back on again because all audio paths have been suspended, and there are no force enabled supply widgets (MICBIAS1 is disabled). The gpio status read after codec power off could be wrong, so the gpio values are checked again after resume.

MCLK1 gets disabled at suspend and re-enabled at resume. Before MCLK1 is re-enabled, if the DSP is already on (either the DSP was left on during suspend, or the DSP is turned on early at resume), i2c register read returns garbage and corrupts the regmap cache. This patch stops the DSP before suspend and restarts it after resume with a dalay to ensure MCLK is on while loading firmware.

The codec dies when RT5677_PWR_ANLG2(MX-64h) is set to 0xACE1 while it's streaming audio over SPI. The DSP firmware turns on PLL2 (MX-64 bit 8) when SPI streaming starts. However regmap does not believe that register can change by itself. When BST1 (bit 15) is turned on with regmap_update_bits(), it doesn't read the register first before write, so PLL2 power bit is cleared by accident. Marking MX-64h as volatile in regmap solved the issue.

Before a hotword is detected, GPIO1 pin is configured as IRQ output so that jack detect works. When a hotword is detected, the DSP firmware configures the GPIO1 pin as GPIO1 and drives a 1. rt5677_irq() is called after a rising edge on the GPIO1 pin, due to either jack detect event or hotword event, or both. All possible events are checked and handled in rt5677_irq() where GPIO1 pin is configured back to IRQ output if a hotword is detected.

The firmware rt5677_elf_vad is an ELF binary obtained from request_firmware(). Sections of the ELF are loaded to the DSP via SPI. A model (e.g. en_us.mmap) can optionally be loaded to the DSP at RT5677_MODEL_ADDR to overwrite the baked-in model in rt5677_elf_vad. Then we switch to DSP mode, load firmware, and let DSP run. When a hotword is detected, an interrupt is fired and rt5677_irq() is called. When 'DSP VAD Switch' is turned off, the codec is set back to normal mode. The kcontrol 'DSP VAD Switch' is automatically enabled/disabled when the hotwording PCM stream is opened/closed.

soc-core has some API which is used from topology, but it is doing topology specific operation at soc-core. soc-core should care about core things, and topology should care about topology things, otherwise, it is very confusable. For example topology type is not related to soc-core, it is topology side issue. This patch removes meaningless check from soc-core. This patch keeps extra initialization/destruction at snd_soc_add_dai_link() / snd_soc_remove_dai_link() which were for topology. From this patch, non-topology card can use it.

If we focus to soc_bind_dai_link() at snd_soc_instantiate_card(), we will notice very complex operation. static int snd_soc_instantiate_card(...) { ... /* * (1) Bind dai_link via card pre-linked dai_link * * Bind dai_link via card pre-linked. * 1 dai_link will be 1 rtd, and connected to card. * for_each_card_prelinks() is for card pre-linked dai_link. * * Image * * card * - rtd(A) * - rtd(A) */ for_each_card_prelinks(card, i, dai_link) { ret = soc_bind_dai_link(card, dai_link); ... } ... /* * (2) Connect card pre-linked dai_link to card list * * Connect all card pre-linked dai_link to *card list*. * Here, (A) means from card pre-linked. * * Image * * card card list * - rtd(A) - dai_link(A) * - rtd(A) - dai_link(A) * - ... - ... */ for_each_card_prelinks(card, i, dai_link) { ret = snd_soc_add_dai_link(card, dai_link); ... } ... /* * (3) Probe binded component * * Each rtd has many components. * Here probes each rtd connected components. * rtd(A) in Image is the probe target. * * During this component probe, topology may add new dai_link to * *card list* by using snd_soc_add_dai_link() which is * used at (2). * Here, (B) means from topology * * Image * * card card list * - rtd(A) - dai_link(A) * - rtd(A) - dai_link(A) * - ... - ... * - dai_link(B) * - dai_link(B) */ ret = soc_probe_link_components(card); ... /* * (4) Bind dai_link again * * Bind dai_link again for topology. * Note, (1) used for_each_card_prelinks(), * here is using for_each_card_links() * * This means from card list. * As Image indicating, it has dai_link(A) (from card pre-link) * and dai_link(B) (from topology). * main target here is dai_link(B). * soc_bind_dai_link() ignores already used * dai_link (= dai_link(A)) * * Image * * card card list * - rtd(A) - dai_link(A) * - rtd(A) - dai_link(A) * - ... - ... * - rtd(B) - dai_link(B) * - rtd(B) - dai_link(B) */ for_each_card_links(card, dai_link) { ret = soc_bind_dai_link(card, dai_link); ... } ... } As you see above, it is doing very complex method. The problem is binding dai_link via "card pre-linked" (= (1)) and "topology added dai_link" (= (3)) are separated. The code can be simple if we can bind dai_link when dai_link is connected to *card list*. This patch do it.

soc_is_dai_link_bound() check will be called both *before* soc_bind_dai_link() (A), and *under* soc_bind_dai_link() (B). These are very verbose code. Let's remove one of them. * static int soc_bind_dai_link(...) { ... (B) if (soc_is_dai_link_bound(...)) { ... return 0; } ... } static int snd_soc_instantiate_card(...) { ... for_each_card_links(...) { (A) if (soc_is_dai_link_bound(...)) continue; * ret = soc_bind_dai_link(...); if (ret) goto probe_end; } ... } Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Reviewed-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Reviewed-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com> Link: https://lore.kernel.org/r/87a79a3jns.wl-kuninori.morimoto.gx@renesas.comSigned-off-by: Mark Brown <broonie@kernel.org>
