Merge series "MFD/extcon/ASoC: Rework arizona codec jack-detect support" from Hans de Goede <hdegoede@redhat.com>: Hi All, Here is v4 of my series to rework the arizona codec jack-detect support to use the snd_soc_jack helpers instead of direct extcon reporting. As discussed before here is a resend rebased on 5.12-rc2, making sure that all patches this depends on are in place. Lee, can you pick-up patches 1-6 through the MFD tree and then send a pull-req to Mark so that Mark can merge the Asoc parts throught the ASoC tree ? Patches 2-6 touch drivers/extcon, these all have an Ack from Chanwoo Choi for merging these through the MFD tree. Here is some more generic info on this series from the previous cover-letter: This is done by reworking the extcon driver into an arizona-jackdet library and then modifying the codec drivers to use that directly, replacing the old separate extcon child-devices and extcon-driver. This brings the arizona-codec jack-detect handling inline with how all other ASoC codec driver do this. This was developed and tested on a Lenovo Yoga Tablet 1051L with a WM5102 codec. This was also tested by Charles Keepax, one of the Cirrus Codec folks. Regards, Hans Hans de Goede (13): mfd: arizona: Drop arizona-extcon cells extcon: arizona: Fix some issues when HPDET IRQ fires after the jack has been unplugged extcon: arizona: Fix various races on driver unbind extcon: arizona: Fix flags parameter to the gpiod_get("wlf,micd-pol") call extcon: arizona: Always use pm_runtime_get_sync() when we need the device to be awake ASoC/extcon: arizona: Move arizona jack code to sound/soc/codecs/arizona-jack.c ASoC: arizona-jack: Move jack-detect variables to struct arizona_priv ASoC: arizona-jack: Use arizona->dev for runtime-pm ASoC: arizona-jack: convert into a helper library for codec drivers ASoC: arizona-jack: Use snd_soc_jack to report jack events ASoC: arizona-jack: Cleanup logging ASoC: arizona: Make the wm5102, wm5110, wm8997 and wm8998 drivers use the new jack library ASoC: Intel: bytcr_wm5102: Add jack detect support MAINTAINERS | 3 +- drivers/extcon/Kconfig | 8 - drivers/extcon/Makefile | 1 - drivers/mfd/arizona-core.c | 20 - sound/soc/codecs/Makefile | 2 +- .../soc/codecs/arizona-jack.c | 577 +++++++----------- sound/soc/codecs/arizona.h | 44 ++ sound/soc/codecs/wm5102.c | 12 +- sound/soc/codecs/wm5110.c | 12 +- sound/soc/codecs/wm8997.c | 14 +- sound/soc/codecs/wm8998.c | 9 + sound/soc/intel/boards/bytcr_wm5102.c | 28 +- 12 files changed, 325 insertions(+), 405 deletions(-) rename drivers/extcon/extcon-arizona.c => sound/soc/codecs/arizona-jack.c (76%) -- 2.30.1 -

Use the snd_soc_jack code to report jack events, instead of using extcon for reporting the cable-type + an input_dev for reporting the button presses. The snd_soc_jack code will report the cable-type through both input_dev events and through ALSA controls and the button-presses through input_dev events. Note that this means that when the codec drivers are moved over to use the new arizona-jack.c library code instead of having a separate MFD extcon cell with the extcon-arizona.c driver, we will no longer report extcon events to userspace for cable-type changes. This should not be a problem since "standard" Linux distro userspace does not (and has never) used the extcon class interface for this. Android does have support for the extcon class interface, but that was introduced in the same release as support for input_dev cable-type events, so this should not be a problem for Android either. Note this also reduces ARIZONA_MAX_MICD_RANGE from 8 to 6, this is ok to do since this info is always provided through pdata (or defaults) and cannot be overridden from devicetree. All in-kernel users of the pdata (and the fallback defaults) define 6 or less buttons/ranges. Reviewed-by:

Convert the arizona extcon driver into a helper library for direct use from the arizona codec-drivers, rather then being bound to a separate MFD cell. Note the probe (and remove) sequence is split into 2 parts: 1. The arizona_jack_codec_dev_probe() function inits a bunch of jack-detect specific variables in struct arizona_priv and tries to get a number of resources where getting them may fail with -EPROBE_DEFER. 2. Then once the machine driver has create a snd_sock_jack through snd_soc_card_jack_new() it calls snd_soc_component_set_jack() on the codec component, which will call the new arizona_jack_set_jack(), which sets up jack-detection and requests the IRQs. This split is necessary, because the IRQ handlers need access to the arizona->dapm pointer and the snd_sock_jack which are not available when the codec-driver's probe function runs. Note this requires that machine-drivers for codecs which are converted to use the new helper functions from arizona-jack.c are modified to create a snd_soc_jack through snd_soc_card_jack_new() and register this jack with the codec through snd_soc_component_set_jack().

Drivers for MFD child-devices such as the arizona codec drivers and the arizona-extcon driver can choose to either make runtime_pm_get/_put calls on their own child-device, which will then be propagated to their parent; or they can make them directly on their MFD parent-device. The arizona-extcon code was using runtime_pm_get/_put calls on its own child-device where as the codec drivers are using runtime_pm_get/_put calls on their parent. The arizona-extcon MFD cell/child-device has been removed and this commit is part of refactoring the arizona-extcon code into a library to be used directly from the codec drivers. Specifically this commit moves the code over to make runtime_pm_get/_put calls on the parent device (on arizona->dev) bringing the code inline with how the codec drivers do this. Note this also removes the pm_runtime_enable/_disable calls as pm_runtime support has already been enabled on the parent-device by the arizona MFD driver. This is part of a patch series converting the arizona extcon driver into a helper library for letting the arizona codec-drivers directly report jack state through the standard sound/soc/soc-jack.c functions.

Controller needs to ensure display power is enabled only for HDA controller reset. Drop the display power-up/down calls from D0i3 entry/exit paths. This was previously not possible as codec drivers could not resume the links, and instead controller kept the reference to display power. The state of display power had be maintained in the D0i3 entry/exit code. With commit 87fc20e4 ("ASoC: SOF: Intel: hda: use hdac_ext fine-grained link management"), this is no longer needed and the code can be cleaned up. Signed-off-by:

Merge series "Fix reset controls and RPM of NVIDIA Tegra ASoC drivers" from Dmitry Osipenko <digetx@gmail.com>: Hi, This series adds missing hardware reset controls to I2S and AC97 drivers, corrects runtime PM usage and drivers probe/remove order. Currently drivers happen to work properly because reset is implicitly deasserted by tegra-clk driver, but clk driver shouldn't touch the resets and we need to fix it because this breaks other Tegra drivers. Previously we fixed the resets of the AHUB and HDMI codec drivers, but turned out that we missed the I2C and AC97 drivers. Thanks to Paul Fertser for testing the pending clk patches and finding that audio got broken on Tegra20 AC100 netbook because of the missing I2S reset. Changelog: v5: - After taking another look at the drivers I noticed couple more things that could be improved. These new patches correct runtime PM and probe/remove order of the drivers: ASoC: tegra20: spdif: Correct driver removal order ASoC: tegra20: spdif: Remove handing of disabled runtime PM ASoC: tegra20: i2s: Add system level suspend-resume callbacks ASoC: tegra20: i2s: Correct driver removal order ASoC: tegra20: i2s: Use devm_clk_get() ASoC: tegra20: i2s: Remove handing of disabled runtime PM ASoC: tegra30: i2s: Correct driver removal order ASoC: tegra30: i2s: Use devm_clk_get() ASoC: tegra30: i2s: Remove handing of disabled runtime PM ASoC: tegra30: ahub: Reset global variable ASoC: tegra30: ahub: Correct suspend-resume callbacks ASoC: tegra30: ahub: Remove handing of disabled runtime PM v4: - Added missing prototype for reset_control_bulk_put(). v3: - Fixed reset stubs for !CONFIG_RESET_CONTROLLER. v2: - After some more testing I found that I2S control logic doesn't require I2S clock to be enabled for resetting. Hence it's fine to have I2S to be reset by parent AHUB driver, so I dropped "tegra30: i2s: Add reset control" patch. - While I was double-checking resets on Tegra30, I found that that Tegra30 I2S driver has a broken runtime PM which doesn't restore hardware state on resume and it's lost after AHUB RPM-resume. Thus, added this new patch "tegra30: i2s: Restore hardware state on runtime PM resume". - Added new patches which switch AHUB driver to use reset-bulk API. I took the RFC patch from Philipp Zabel, fixed it and added devm_reset_control_bulk_optional_get_exclusive_released() that will be useful for further Tegra GPU patches. This is a minor improvement which makes code cleaner.
