Add a clock control driver to initialize the clock tree inside the low-power audio subsystem. Depthcharge builds up on this to enable audio function on storm. The clock is hardcoded for 48KHz frame rate, two 16 bit channels. BRANCH=storm BUG=chrome-os-partner:35247 TEST=with depthcharge patches applied and Using depthcharge CLI audio test program verified that the target generates sensible sounds audio 100 100 audio 1000 5000 Change-Id: I56513fc782657ade99b6e43b2d5d3141d27ecc4e Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 0d4f408408aa38b2f0ee19b83ed490de39074760 Original-Change-Id: If8ffc326698fcea17e05d536930d927ca553481f Original-Signed-off-by: Kenneth Westfield <kwestfie@codeaurora.org> Original-Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/248830 Original-Reviewed-by: Dylan Reid <dgreid@chromium.org> Reviewed-on: http://review.coreboot.org/9758 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.
