Cristian Ciocaltea 3b575d9302 ASoC: es8316: Increment max value for ALC Capture Target Volume control [ Upstream commit `6f07342903` ] The following error occurs when trying to restore a previously saved ALSA mixer state (tested on a Rock 5B board): $ alsactl --no-ucm -f /tmp/asound.state store hw:Analog $ alsactl --no-ucm -I -f /tmp/asound.state restore hw:Analog alsactl: set_control:1475: Cannot write control '2:0:0:ALC Capture Target Volume:0' : Invalid argument According to ES8316 datasheet, the register at address 0x2B, which is related to the above mixer control, contains by default the value 0xB0. Considering the corresponding ALC target bits (ALCLVL) are 7:4, the control is initialized with 11, which is one step above the maximum value allowed by the driver: ALCLVL \| dB gain -------+-------- 0000 \| -16.5 0001 \| -15.0 0010 \| -13.5 .... \| ..... 0111 \| -6.0 1000 \| -4.5 1001 \| -3.0 1010 \| -1.5 .... \| ..... 1111 \| -1.5 The tests performed using the VU meter feature (--vumeter=TYPE) of arecord/aplay confirm the specs are correct and there is no measured gain if the 1011-1111 range would have been mapped to 0 dB: dB gain \| VU meter % --------+----------- -6.0 \| 30-31 -4.5 \| 35-36 -3.0 \| 42-43 -1.5 \| 50-51 0.0 \| 50-51 Increment the max value allowed for ALC Capture Target Volume control, so that it matches the hardware default. Additionally, update the related TLV to prevent an artificial extension of the dB gain range.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
