[RESEND PATCH 1/6] mfd: stmpe: root out static GPIO and IRQ assignments

[Linus Walleij]

The only platform using the STMPE expander now boots from
device tree using all-dynamic GPIO and IRQ number assignments, so
remove the mechanism to pass this from the device tree entirely.

[RESEND PATCH 2/6] mfd: stmpe: add optional regulators

[Linus Walleij]

The STMPE has VCC and VIO supply lines, and sometimes (as on
Ux500) this comes from a software-controlled regulator. Make
it possible to supply the STMPE with power from these
regulators.

[RESEND PATCH 3/6] mfd: stmpe: probe properly from the device tree

[Linus Walleij]

The current STMPE I2C probing code does not really match the
compatible strings - it matches node names happening to give
the right device name. Instead, let's introduce some real
compatible matching, more complex, more accurate. Make the
driver depend on OF since all platforms using it are DT-only.

Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
---
ChangeLog v2->v3:
- Fix a stupid error where I left a dangling return statement
  in the probe path.
- Fix up subject prope->probe
ChangeLog v1->v2:
- Make driver depend on OF and remove some ifdeffery that way.
- Squash OF match table to single lines.
- Merge of-specific probe function into probe().
- Print a small nag if DT is using the node name trick to make
  the driver probe.

[RESEND PATCH 4/6] mfd: stmpe: mask off unused blocks properly

[Linus Walleij]

The STMPE driver would just read/modify/write the system control
register on the STMPE1601, meaning it would not properly mask off
the PWM block, which remained active if it was on at boot time.
This makes sure the blocks are always masked off if they were
active on boot, saving some power. Also rename the inconsistenty
named STMPE1601 define for the PWM block activation.
