[RESEND] [PATCHv6 0/4] 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.

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.

 - switch from "diag," to "dlg," prefix
 - add/use defines for accessing bits in registers
