[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.

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

Changes since original PATCHv6
 - No functional changes
 - Added Acked-by from Lee Jones [MFD]
 - Added Acked-by from Guenter Roeck [HWMON]

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

[RESEND] [PATCHv6 2/4] mfd: da9052: make touchscreen registration optional

[Sebastian Reichel]

If the touchscreen pins are used as general purpose analogue
input, the touchscreen driver should not be used. The pins
will be handled by the existing hwmon driver instead.

[RESEND] [PATCHv6 4/4] hwmon: da9052: add support for TSI channel

[Sebastian Reichel]

TSI channel has a 4 channel mux connected to it and is normally
used for touchscreen support. The hardware may alternatively
use it as general purpose adc.

Hi Lee,

I noticed, that you did not yet push out your for-mfd-next branch,
so the patches did not yet appear in linux-next. Was this
intentional?
