 "The second part of the multiplatform changes now converts the
  Intel/Marvell PXA platform along with the rest. The patches went
  through several rebases before the merge window as bugs were found, so
  they remained separate.

  This has to touch a lot of drivers, in particular the touchscreen,
  pcmcia, sound and clk bits, to detach the driver files from the
  platform and board specific header files"

The leds-trigger-pattern documentation describes how the brightness of
the LED should transition linearly from one brightness value to the
next, over the given delta_t.

But the pattern engine in the Qualcomm LPG hardware only supports
holding the brightness for each entry for the period.
This subset of patterns can be represented in the leds-trigger-pattern
by injecting zero-time transitions after each entry in the pattern,
resulting in a pattern that pattern that can be rendered by the LPG.

Rework LPG pattern interface to require these zero-time transitions, to
make it comply with this subset of patterns and reject the patterns it
can't render.

Returning an error value from an i2c remove callback results in an error
message being emitted by the i2c core, but otherwise it doesn't make a
difference. The device goes away anyhow and the devm cleanups are
called.

As stk3310_set_state() already emits an error message on failure and the
additional error message by the i2c core doesn't add any useful
information, don't pass the error value up the stack. Instead continue
to clean up and return 0.

This patch is a preparation for making i2c remove callbacks return void.

The Qualcomm LPG driver fails to probe unless PWM support is enabled so
add the missing Kconfig dependency.

Make the AUX pin optional, since it isn't a core part of functionality,
and the device is designed to be operational with only one CTRL pin.

Use dev_err_probe instead of dev_err to avoid duplicate error
messages if the GPIO allocation makes the probe defer.

Returning an error value in an i2c remove callback results in a generic
error message being emitted by the i2c core, but otherwise it doesn't make
a difference. The device goes away anyhow and the devm cleanups are
called.

So instead of triggering the generic i2c error message, emit a more helpful
message if a problem occurs and return 0 to suppress the generic message.

This patch is a preparation for making i2c remove callbacks return void.

By allowing to group multiple monochrome PWM LEDs into multicolor LEDs,
all involved LEDs can be controlled in-sync. This enables using effects
using triggers, etc.

The regulator LED can easily be adapted to probe from the
device tree.

We switch led_classdev_register() to led_classdev_register_ext()
passing some struct led_init_data init_data that we leave NULL
save the fwnode if platform data isn't present so that it will be
populated from the device tree.

If we have platform data we set up the name from the platform
data but using init_data instead.
