The Ryu RT5677 audio codec uses EXTPERIPH1 clock (12MHz) for MCLK1, I2S1 for input. AHUB needs all of its child peripherals taken out of reset and enabled, too. This just sets up the audio clocks. More work still to be done in the codec driver, and some kind of stub needs to be created/hacked to set up the AD4567 speaker amp regs for mono output on P1. BUG=chrome-os-partner:32582 BRANCH=none TEST=Dumped clock regs and saw correct values Change-Id: Ifb6551f1e09b38f440f3bb7c759b5e6c0b9e4e44 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 48f989a0291044f5fb4340cc89546325d819d82f Original-Change-Id: I6c9e760ac39def92a6054d673f781facdbfd70a2 Original-Signed-off-by: Tom Warren <twarren@nvidia.com> Original-Reviewed-on: https://chromium-review.googlesource.com/229993 Original-Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/9523 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org> |

------------------------------------------------------------------------------- coreboot README ------------------------------------------------------------------------------- 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. Payloads -------- After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot. See http://www.coreboot.org/Payloads for a list of supported payloads. Supported Hardware ------------------ coreboot supports a wide range of chipsets, devices, and mainboards. For details please consult: * http://www.coreboot.org/Supported_Motherboards * http://www.coreboot.org/Supported_Chipsets_and_Devices Build Requirements ------------------ * gcc / g++ * make Optional: * doxygen (for generating/viewing documentation) * iasl (for targets with ACPI support) * gdb (for better debugging facilities on some targets) * ncurses (for 'make menuconfig') * flex and bison (for regenerating parsers) Building coreboot ----------------- Please consult http://www.coreboot.org/Build_HOWTO for details. Testing coreboot Without Modifying Your Hardware ------------------------------------------------ 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 http://www.coreboot.org/QEMU for details. Website and Mailing List ------------------------ Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website: http://www.coreboot.org You can contact us directly on the coreboot mailing list: http://www.coreboot.org/Mailinglist Copyright and License --------------------- The copyright on coreboot is owned by quite a large number of individual developers and companies.
