Subject: [PATCH v2] ALSA: hda: cs35l41: Support ASUS 2023 laptops with missing
 DSD

Support adding the missing DSD properties required  for ASUS ROG 2023
laptops and other ASUS laptops to properly utilise the cs35l41.

The currently added laptops are:
- ASUS GS650P,   i2c
- ASUS GA402X,   i2c
- ASUS GU604V,   spi
- ASUS GU603V,   spi
- ASUS GV601V,   spi
- ASUS GZ301V,   spi
- ASUS ROG ALLY, i2c
- ASUS G614J,    spi
- ASUS G634J,    spi
- ASUS G614JI,   spi
- ASUS G713P,    i2c
- ASUS H7604JV,  spi

The SPI connected amps may be required to use an external DSD patch
to fix or add the "cs-gpios" property.

From b35a4c957b3f0e5b4c7c73dec4fe3a5b9dbc4873 Mon Sep 17 00:00:00 2001

Subject: [PATCH v6 1/1] platform/x86: asus-wmi: add support for ASUS screenpad

Add support for the WMI methods used to turn off and adjust the
brightness of the secondary "screenpad" device found on some high-end
ASUS laptops like the GX650P series and others.

There are some small quirks with this device when considering only the
raw WMI methods:
1. The Off method can only switch the device off
2. Changing the brightness turns the device back on
3. To turn the device back on the brightness must be > 1
4. When the device is off the brightness can't be changed (so it is
   stored by the driver if device is off).
5. Booting with a value of 0 brightness (retained by bios) means the bios
   will set a value of >0 <15
6. When the device is off it is "unplugged"

asus_wmi sets the minimum brightness as 20 in general use, and 60 for
booting with values <= min.

The ACPI methods are used in a new backlight device named asus_screenpad.

Subject: [PATCH] ALSA: hda/realtek: Add quirk for ASUS ROG G814Jx

Adds the required quirk to enable the Cirrus amp and correct pins
on the ASUS ROG G814J series which uses an SPI connected Cirrus amp.

While this works if the related _DSD properties are made available, these
aren't included in the ACPI of these laptops (yet).
