Subject: [PATCH v2 0/6] Introduce Embedded Controller driver for Acer A500

Hello!

This series adds support for the Embedded Controller which is found on
Acer Iconia Tab A500 (Android tablet device).

The Embedded Controller is ENE KB930 and it's running firmware customized
for the A500. The firmware interface may be reused by some other sibling
Acer tablets, although none of those tablets are supported in upstream yet.
Please review and apply, thanks in advance!

Changelog:

v2: - Factored out KB930 device-tree binding into a separate file, like it
      was suggested by Lubomir Rintel.

    - Switched to use regmap API like it was suggested by Lubomir Rintel.

    - Added patch "regmap: Use flexible sleep" which allows not to hog
      CPU while LED is switching state.

    - Corrected MODULE_LICENSE to use "GPL" in all patches.

    - Corrected MFD driver Kconfig entry like it was suggested by
      Lubomir Rintel, it now depends on I2C.

    - Switched to use I2C probe_new() in the MFD driver.

    - Renamed the global pm_off variable, like it was suggested by
      Lubomir Rintel and Lee Jones.

    - Dropped serial number from the battery driver because I realized
      that it's not a battery serial, but a device serial.

    - Battery driver now uses dev_err_probe(), like it was suggested by
      Sebastian Reichel.

    - Dropped legacy LED_ON usage from the LED driver and renamed the
      LEDs, like it was suggested by Pavel Machek. I also checked whether
      LED-name customization via device-tree could be needed by other
      potentially compatible devices and it shouldn't be needed, anyways it
      won't be difficult to extend the code even if I'm wrong.
