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
