[PATCHv5 0/6] DA9052 hardware monitoring improvements

[Sebastian Reichel]

Hi,

GE Healthcare's PPD [0] uses DA9053's touchscreen pins
for hardware monitoring purposes. This adds support for
the feature and fixes a bug, which came up during
stress-testing of the driver.

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
