Subject: [PATCHv6 0/4] DA9052 hardware monitoring improvements

Hi,

GE Healthcare's PPD [0] uses DA9053's touchscreen pins
for hardware monitoring purposes. This adds support for
the feature.

The proposed merge solution is, that mfd queues the
mfd patches and provides an immutable branch for hwmon,
since the last patch depends on the other ones.

[0] https://patchwork.kernel.org/patch/9809681/

Changes since PATCHv5
 - drop patch 1 & 2 (applied to mfd)
 - use one line for da9052_tsi_subdev_info[]

Changes since PATCHv4:
 - split mfd changes from main hwmon patch

Changes since PATCHv3:
 - use correct index in da9052_channel_is_visible()
 - disable touchscreen in mfd instead of in ts driver

Changes since PATCHv2:
 - switch from "diag," to "dlg," prefix
 - add/use defines for accessing bits in registers
 - provide more details in the comment above early exit
   in touchscreen driver
 - switch to da9052_group_read() to ensure MSB and LSB
   are in sync
 - move binding update into its own patch
 - rename patch

Changes since PATCHv1:
 - convert tsiref-microvolt property into proper regulator
 - drop error message for timeout
 - simplify da9052_channel_is_visible()
 - fix checkpatch warnings
