Merge series "MFD/ASoC: Add support for Intel Bay Trail boards with WM5102 codec" from Hans de Goede <hdegoede@redhat.com>:
Hi All, Here is v4 of my series to add support for Intel Bay Trail based devices which use a WM5102 codec for audio output/input. This was developed and tested on a Lenovo Yoga Tablet 1051L. The MFD and ASoC parts do not have any build-time dependencies on each other. But the follow-up jack-detect series does have patches depending on each-other and on this series. So IMHO it would be best if this entire series would be merged through the MFD tree to make merging the follow-up series easier. Mark, if that is ok with you (and you are happy with the ASoC changes) can you please Ack this ? Changes in v4: - Add a comment to the irq-flags override explaining that theoretically DSDTs using IRQF_TRIGGER_FALLING could be correct on boards where the IRQ controller does not support active low level interrupts Changes in v3: - Fix compilation error when CONFIG_ACPI is not set Changes in v2: - Split my WM5102 work into 2 series, one series adding basic support for Bay Trail boards with a WM5102 codec and a second series with the jack-detect work - Various other minor code tweaks Hans de Goede (4): mfd: arizona: Add MODULE_SOFTDEP("pre: arizona_ldo1") mfd: arizona: Replace arizona_of_get_type() with device_get_match_data() mfd: arizona: Add support for ACPI enumeration of WM5102 connected over SPI ASoC: Intel: Add DMI quirk table to soc_intel_is_byt_cr() Pierre-Louis Bossart (1): ASoC: Intel: bytcr_wm5102: Add machine driver for BYT/WM5102 drivers/mfd/arizona-core.c | 11 - drivers/mfd/arizona-i2c.c | 11 +- drivers/mfd/arizona-spi.c | 138 +++++- drivers/mfd/arizona.h | 9 - sound/soc/intel/boards/Kconfig | 12 + sound/soc/intel/boards/Makefile | 2 + sound/soc/intel/boards/bytcr_wm5102.c | 465 ++++++++++++++++++ .../intel/common/soc-acpi-intel-byt-match.c | 16 + sound/soc/intel/common/soc-intel-quirks.h | 25 + 9 files changed, 661 insertions(+), 28 deletions(-) create mode 100644 sound/soc/intel/boards/bytcr_wm5102.c Regards, Hans
