Subject: [PATCH v5 00/15] sx9310 iio driver updates

The first patch resends the DT binding for the driver that was merged in
v5.8-rc1 with a small change to update for proper regulators. The second
through the eleventh patch fixes several issues dropped from v8 to v9
when the initial patch was merged.  The twelveth patch drops
channel_users because it's unused. The thirteenth patch adds support to
enable the svdd and vdd supplies so that this driver can work on a board
where the svdd supply isn't enabled at boot and needs to be turned on
before this driver starts to communicate with the chip. The final patch
updates irq trigger flags.

Changes in v5:
 - Added #include <linux/bitfield.h>
 - Really use a pointer to buffer struct on
iio_push_to_buffers_with_timestamp().

Changes in v4:
 - Updated macro SX9310_REG_STAT1_COMPSTAT_MASK at call site.
 - Use FIELD_GET/FIELD_PREP instead of manual shift.
 - Reverted condition check logic on enable/disable_irq methods.
 - Use pointer to buffer struct on iio_push_to_buffers_with_timestamp().

Changes in v3:
 - Moved irq presence check down to lower methods
 - Changed buffer to struct type to align timestamp memory properly.
 - Added static assert for number of channels.
 - Added irq trigger flags commit to the series.

Changes in v2:
 - Added #io-channel-cells as a required property
 - Reordered error handling on sx9310_resume()
 - Added #include <linux/mod_devicetable.h>
 - Added '\n' to dev_err()
 - Fixed commit message from "iio: sx9310: Align memory"
 - Changed prox_stat to chan_prox_stat bitmap.
 - Fixed dev_err() message
 - Added '\n' to dev_err()
