Hardware: - The 16ACHg6 laptop has two CS35L41 amplifiers, connected to Realtek ALC287 by an I2S bus and by and direct I2C to the CPU. - The ALC287 codec is connected to the CPU by an HDA bus. - The CS35L41 has a DSP which will require firmware to be loaded. Architecture: - To load the firmware for CS35L41, this solution will require the wm_adsp library, which requires regmap, header definitions and register tables. - To minimize the duplication of the code, the HDA functions will be placed inside the ASoC CS35L41 driver. - Finally, HDA patch_realtek will access exposed functions from ASoC CS35L41 driver to initialize the amplifiers, start and stop streams and load firmware. Notes: - This is a work in progress, so the code is not functional, its only intent is to demonstrate the overall solution - If accepted, this will be split into a couple of patches for a new patch chain Signed-off-by: Lucas Tanure --- drivers/acpi/scan.c | 1 + drivers/platform/x86/i2c-multi-instantiate.c | 7 ++ include/sound/cs35l41.h | 4 ++ sound/pci/hda/Kconfig | 1 + sound/pci/hda/patch_realtek.c | 21 +++++- sound/soc/codecs/cs35l41.c | 75 ++++++++++++++++---- 6 files changed, 95 insertions(+), 14 deletions(-) diff --git a/drivers/acpi/scan.c b/drivers/acpi/scan.c index 5b54c80b9d32..c1c27a408420 100644 --- a/drivers/acpi/scan.c +++ b/drivers/acpi/scan.c @@ -1703,6 +1703,7 @@ static bool acpi_device_enumeration_by_parent(struct acpi_device *device) {"BSG2150", }, {"INT33FE", }, {"INT3515", }, + {"CLSA0100", }, {} }; diff --git a/drivers/platform/x86/i2c-multi-instantiate.c b/drivers/platform/x86/i2c-multi-instantiate.c index a50153ecd560..b61f7e30d42a 100644 --- a/drivers/platform/x86/i2c-multi-instantiate.c +++ b/drivers/platform/x86/i2c-multi-instantiate.c @@ -139,6 +139,12 @@ static const struct i2c_inst_data bsg2150_data[] = { {} }; +static const struct i2c_inst_data clsa0100_data[] = { + { "cs35l41", IRQ_RESOURCE_GPIO, 0 }, + { "cs35l41", IRQ_RESOURCE_GPIO, 0 }, + {} +}; + /* * Device with _HID INT3515 (TI PD controllers) has some unresolved interrupt * issues.
