i2c: Make remove callback return void

2022-08-16T10:46:26+00:00

The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

drm/i2c/sil164: Drop no-op remove function

2022-08-16T10:33:39+00:00

A remove callback that just returns 0 is equivalent to no callback at all as can be seen in i2c_device_remove(). So simplify accordingly. Signed-off-by: Uwe Kleine-König Signed-off-by: Wolfram Sang

Pull sound updates from Takashi Iwai: "As the diffstat shows, we've had lots of developments in a wide range at this time; the majority of changes are about ASoC, including subsystem-wide cleanups, continued SOF / Intel updates and a bunch of new drivers (as usual), while there have been some significant (but almost invisible) improvements in ALSA core side, too. Below are some highlights: Core: - Faster lookups of control elements with Xarray; normal user won't notice, but on the devices with tons of control elements, it can be visibly faster - Support for input validation for controls; this will harden for badly written drivers in general with a slight overhead - Deferred async signal handling for working around the potential deadlocks - Cleanup / refactoring raw MIDI locking code ASoC: - Restructing of the set_fmt() callbacks for making things clearer in situations like CODEC to CODEC links - Clean up and modernizing the DAI naming scheme setups - Merge of more of the Intel AVS driver stack, including some board integrations - New version 4 mechanism for communication with SOF DSPs - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms - Improvements for CODEC to CODEC support in the generic cards - Support for AMD Jadeite and various machines, AMD RPL, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780 HD- and USB-audio: - Continued improvement for CS35L41 (sub)codec support - More quirks for various devices (HP, Lenovo, Dell, Clevo)" * tag 'sound-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (778 commits) ALSA: hda/realtek: Add quirk for HP Spectre x360 15-eb0xxx ALSA: line6: Replace sprintf() with sysfs_emit() ALSA: hda: Replace sprintf() with sysfs_emit() ALSA: pcm: Replace sprintf() with sysfs_emit() ALSA: core: Replace scnprintf() with sysfs_emit() ALSA: control-led: Replace sprintf() with sysfs_emit() ALSA: aoa: Replace sprintf() with sysfs_emit() ALSA: ac97: Replace sprintf() with sysfs_emit() ALSA: hda/realtek: Add quirk for Clevo NV45PZ ALSA: hda/realtek: Add quirk for Lenovo Yoga9 14IAP7 ALSA: control: Use deferred fasync helper ALSA: pcm: Use deferred fasync helper ALSA: timer: Use deferred fasync helper ALSA: core: Add async signal helpers ASoC: q6asm: use kcalloc() instead of kzalloc() ACPI: scan: Add CLSA0101 Laptop Support ALSA: hda: cs35l41: Support CLSA0101 ALSA: hda: cs35l41: Use the CS35L41 HDA internal define ASoC: dt-bindings: use spi-peripheral-props.yaml ASoC: codecs: va-macro: use fsgen as clock ...

drm: Remove linux/i2c.h from drm_crtc.h

2022-07-05T18:15:23+00:00

drm_crtc.h has no need for linux/i2c.h, so don't include it. Avoids useless rebuilds of the entire universe when touching linux/i2c.h. Quite a few placs do currently depend on linux/i2c.h without actually including it directly. All of those need to be fixed up. v2: imx and mcde need linux/io.h for readl()/etc. Acked-by: Sam Ravnborg Acked-by: Jani Nikula Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20220630195114.17407-5-ville.syrjala@linux.intel.com

ASoC: hdmi-codec: Update to modern DAI terminology

2022-06-13T13:56:07+00:00

As part of retiring the old defines used to specify DAI formats update the hdmi_codec driver to use the modern names, including the variables in the struct hdmi_codec_daifmt exported to the DRM drivers. In updating this I did note that the only use of this information in DRM drivers is to reject clock provider settings, thinking about what this hardware is doing I rather suspect that there might not be any hardware out there which needs the configuration so it may be worth considering just having hdmi-codec support only clock consumer.

ASoC: hdmi-codec: merge .digital_mute() into .mute_stream()

2020-07-16T22:06:06+00:00

snd_soc_dai_digital_mute() is internally using both mute_stream() (1) or digital_mute() (2), but the difference between these 2 are only handling direction. We can merge digital_mute() into mute_stream int snd_soc_dai_digital_mute(xxx, int direction) { ... else if (dai->driver->ops->mute_stream) (1) return dai->driver->ops->mute_stream(xxx, direction); else if (direction == SNDRV_PCM_STREAM_PLAYBACK && dai->driver->ops->digital_mute) (2) return dai->driver->ops->digital_mute(xxx); ... } For hdmi-codec, we need to update struct hdmi_codec_ops, and all its users in the same time.

drm: bridge: Pass drm_display_info to drm_bridge_funcs .mode_valid()

2020-06-23T17:53:27+00:00

When validating a mode, bridges may need to do so in the context of a display, as specified by drm_display_info. An example is the meson dw-hdmi bridge that needs to consider the YUV 4:2:0 output format to perform clock calculations. Bridges that need the display info currently retrieve it from the drm_connector created by the bridge. This gets in the way of moving connector creation out of bridge drivers. To make this possible, pass the drm_display_info to drm_bridge_funcs .mode_valid(). Changes to the bridge drivers have been performed with the following coccinelle semantic patch and have been compile-tested. @ rule1 @ identifier funcs; identifier fn; @@ struct drm_bridge_funcs funcs = { ..., .mode_valid = fn }; @ depends on rule1 @ identifier rule1.fn; identifier bridge; identifier mode; @@ enum drm_mode_status fn( struct drm_bridge *bridge, + const struct drm_display_info *info, const struct drm_display_mode *mode ) { ... } Signed-off-by: Laurent Pinchart Reviewed-by: Neil Armstrong Reviewed-by: Boris Brezillon Reviewed-by: Guido Günther # for the nwl-dsi part: Signed-off-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20200526011505.31884-11-laurent.pinchart+renesas@ideasonboard.com
