2022-10-27media: i2c: imx290: Fix max gain valueLaurent Pinchart1-1/+14
The gain is expressed in multiple of 0.3dB, as a value between 0.0dB and 72.0dB. Gains between 0.0dB and 30.0dB (included) apply analog gain only, higher gains from 30.3dB to 72dB apply additional digital gain. The maximum gain value is erroneously set to 72. Increase it to 100 to cover the whole analog gain range. Support for digital gain can be added separately if needed. The IMX327 and IMX462 are largely compatible with the IMX290, but have an analog gain range of 0.0dB to 29.4dB and 42dB of digital gain. When support for those sensors gets added to the driver, the gain control should be adjusted accordingly.

2022-10-27media: i2c: imx290: Simplify error handling when writing registersLaurent Pinchart1-54/+32
Error handling for register writes requires checking the error status of every single write. This makes the code complex, or incorrect when the checks are omitted. Simplify this by passing a pointer to an error code to the imx290_write_reg() function, which allows writing multiple registers in a row and only checking for errors at the end. While at it, rename imx290_write_reg() to imx290_write() as there's nothing else than registers to write, and rename imx290_read_reg() accordingly.

When moving the input selection to adv748x_reset() it was missed that during probe the device is reset _before_ the initialization and parsing of DT by the AFE subdevice.

2022-08-16i2c: Make remove callback return voidUwe Kleine-König137-359/+137
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.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound 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 ...
