drivers/soundwire/alc1308 : Add ALC1308 soundwire device This patch adds new soundwire device ALC1308 The codec properties are filled out as best as possible with the datasheet as a reference. The ACPI address for the codec is calculated with the information in the codec driver combined with the devicetree.cb hierarchy where the link and unique IDs are extracted from the device path. The unique ID is calculated from schematics by referring to ASEL[1:0] strap settings. Datasheet of ALC1308 provides info about the mapping of ASEL strap settings to unique ID For example this device is connected to master link ID 1 and has strap settings configuring it for unique ID 2. chip drivers/soundwire/alc1308 register "desc" = ""Left Speaker"" device generic 1.2 on end end Bug=None Test=Build and boot on TGLRVP.Extract SSDT and confirm that the entries for PCI0.HDAS.SNDW are present for ALC1308 Test speaker out functionality Signed-off-by: Anil Kumar <anil.kumar.k@intel.com> Change-Id: Ibf3f1d5c6881cbd106e96ad1ff17ca216aa272ac Reviewed-on: https://review.coreboot.org/c/coreboot/+/51042 Reviewed-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-by: Sathyanarayana Nujella Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.
With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.
coreboot was formerly known as LinuxBIOS.
After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot.
See https://www.coreboot.org/Payloads for a list of supported payloads.
coreboot supports a wide range of chipsets, devices, and mainboards.
For details please consult:
ANY_TOOLCHAIN Kconfig option if you're feeling lucky (no support in this case).Optional:
make menuconfig and make nconfig)Please consult https://www.coreboot.org/Build_HOWTO for details.
If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU.
Please see https://www.coreboot.org/QEMU for details.
Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
