Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>: This patch chain adds support for the Cirrus Logic cs42l43 PC focused SoundWire CODEC. The chain is currently based of Lee's for-mfd-next branch. This series is mostly just a resend keeping pace with the kernel under it, except for a minor fixup in the ASoC stuff.

Add filter bypass mode, which bypasses the low pass filter, high pass filter and disables/unregister the clock rate notifier. Currently a feature like bypassing the filter is not achievable straightforward and not very deductive. The user has to look through the code and call the set_lpf_3db_frequency and set_hpf_3db_frequency iio attributes from the user interface using the corner cases (freq > largest lpf supported by the part, respectively freq < smallest hpf supported by the part). Moreover, in such case of bypassing the filter, the input clock rate change might mess up things so we want to make sure that it is disabled. Also, the feature will help emphasizing the filter behavior, therefore adding it in the userspace will ease the charcaterization of the filter's effects when active/disabled. It was requested by users of the driver to ease the interaction with different configuration modes of the device.

The ROHM BU27010 is an RGBC sensor with a flickering detection FIFO. The
RGBC+IR sensor functionality is largely similar to what the BU27008 has.
There are some notable things though:
- gain setting is once again new and exotic. Now, there is 6bit gain
setting where 4 of the bits are common to all channels and 2 bits
can be configured separately for each channel. The BU27010 has
similar "1X on other channels vs 2X on IR when selector is 0x0"
gain design as BU27008 had. So, we use same gain setting policy for
BU27010 as we did for BU27008 - driver sets same gain selector for all
channels but shows the gains separately for all channels so users
can (at least in theory) detect this 1X vs 2X madness...
- BU27010 has suffled all the control register bitfields to new
addresses and bit positions while still keeping the register naming
same.
- Some more power/reset control is added.
- FIFO for "flickering detection" is added.
The control register suffling made this slightly nasty. Still, it is
easier for maintenance perspective to add the BU27010 support in BU27008
driver because - even though the bit positions/addresses were changed -
most of the driver structure can be re-used. Writing own driver for
BU27010 would mean plenty of duplicate code albeit a tad more clarity.
The flickering FIFO is not supported by the driver.
Add BU27010 RGBC+IR support to rohm-bu27008 driver.

The ROHM BU27010 RGB + flickering sensor is in many regards similar to the BU27008.

Add regulators for the VCC supplies of the admv1013. The patch aims to align the implementation with the current admv1014 driver where all the VCC supplies are handled as regulators.

This function call was found to be unnecessary as there is no equivalent platform_get_drvdata() call to access the private data of the driver. Also, the private data is defined in this driver, so there is no risk of it being accessed outside of this driver file.
