mfd: stmpe: PWM on 24xx has altfunc 1

2015-10-26T14:48:57+00:00

On the STMPE2401 and STMPE2401 altfunction 1 corresponds to the
PWM channels. This oneliner was missing in the case-switch, making
it impossible to enable the PWM channel output.

mfd: Kill off set_irq_flags usage

2015-08-11T14:09:01+00:00

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

Constify in various drivers configuration data which is not modified:
 - regmap_irq_chip,
 - individual regmap_irq's in array,
 - regmap_config,
 - irq_domain_ops,

  timestamps, in addition to real and monotonic timestamps"

mfd: stmpe: add pull up/down register offsets for STMPE

2014-12-16T05:46:11+00:00

This adds the register offsets for pull up/down for the STMPE
1601, 1801 and 24xx expanders. This is used to bias GPIO lines
and keypad lines.

mfd: stmpe: Support gpio over irq under device tree

2014-09-26T07:23:53+00:00

The stmpe_platform_data has a irq_over_gpio field, which allows the
system to read STMPE events whenever an IRQ occurs on a GPIO pin.
This patch adds the ability to configure this field and to use a GPIO
as an IRQ source for boards configuring the STMPE in device tree.

mfd: stmpe: root out static GPIO and IRQ assignments

2014-05-23T08:41:01+00:00

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.

mfd: stmpe: add optional regulators

2014-05-09T09:51:12+00:00

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.
