[PATCH v2 0/3] ALSA: Add support for new HP G12 laptops

[PATCH v2 0/3] ALSA: Add support for new HP G12 laptops

[Richard Fitzgerald]

Add support for HP G12 laptops that use CS35L54 or CS35L56 amplifiers
with Realtek HDA codecs. Some of these use the same SSID for models with
CS35L54 and models with CS35L56 so the ACPI entries are examined to
determine which amp is present.

To avoid having to #ifdef around this code we've fixed the definitions
of SPI and I2C functions that were not correctly supplying dummy functions
when the real functions are not in the build.

Changes since V1:
Added I2C and SPI patches to provide dummy functions.

[PATCH v2 1/3] spi: Add empty versions of ACPI functions

[Richard Fitzgerald]

Provide empty versions of acpi_spi_count_resources(),
acpi_spi_device_alloc() and acpi_spi_find_controller_by_adev()
if the real functions are not being built.

This commit fixes two problems with the original definitions:

1) There wasn't an empty version of these functions
2) The #if only depended on CONFIG_ACPI. But the functions are implemented
   in the core spi.c so CONFIG_SPI_MASTER must also be enabled for the real
   functions to exist.

[PATCH v2 2/3] i2c: Fix conditional for substituting empty ACPI functions

[Richard Fitzgerald]

Add IS_ENABLED(CONFIG_I2C) to the conditional around a bunch of ACPI
functions.

The conditional around these functions depended only on CONFIG_ACPI.
But the functions are implemented in I2C core, so are only present if
CONFIG_I2C is enabled.

[PATCH v2 3/3] ALSA: hda/realtek: Add support for new HP G12 laptops

[Richard Fitzgerald]

From: Simon Trimmer <simont@opensource.cirrus.com>

Some of these laptop models have quirk IDs that are identical but have
different amplifier parts fitted, this difference is described in the
ACPI information.

The solution introduced for this product family can derive the required
component binding information from ACPI instead of hardcoding it,
supports the new variants of the CS35L56 being used and has generalized
naming that makes it applicable to other ALC+amp combinations.

[1/3] spi: Add empty versions of ACPI functions
      commit: 90ec3a8a7fd0d43026fcca979713e077d4883b56

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Hm, the 3rd patch requires both patch 1 and 2, and now those seem to
have been applied to two different trees, which makes hard to apply
the 3rd one.

Mark, Wolfram, will you guys submit PR for 6.11-rc3 including the
patch 1 and 2?  If so, I can apply the patch 3 later on top of
6.11-rc3.

Or, I'd need to pull from both of you and apply the patch 3.

Takashi

spi: Add empty versions of ACPI lookup functions

A patch from Richard Fitzgerald adding dummy versions of the ACPI lookup
functions for SPI:

    Provide empty versions of acpi_spi_count_resources(),
    acpi_spi_device_alloc() and acpi_spi_find_controller_by_adev()
    if the real functions are not being built.

    This commit fixes two problems with the original definitions:

    1) There wasn't an empty version of these functions
    2) The #if only depended on CONFIG_ACPI. But the functions are implemented
       in the core spi.c so CONFIG_SPI_MASTER must also be enabled for the real
       functions to exist.

We've just noticed that the SPI patches have gone into for-6.12.
We really hoped that we could get the main patch (G12 support) into
6.11 (yes, I know, I didn't actually say that we were targeting 6.11 -
sorry).

I also planned for 6.12, but fortunately didn't take it yet, so it's
no problem :)

And, I see Mark's PR is based on Linus tree, so that's fine to take.
The remaining question is about the i2c patch.

Wolfram, has the patch been merged for your branch for 6.11?  If yes,
can I pull your change, so that I can apply the patch 3 together with
the SPI change?


thanks,

Takashi

Yes, you can pull i2c/for-current. Maybe I can also retrofit an
immutable branch for you. I'd think, though, that it is easiest to wait
for 6.11-rc3 which will include the I2C part of this series. Or?
