The CHRG_CTRL1 and CHRG_CTRL2 registers are made for controlling
different battery charging settings such as the constant current charge
value.

The AXP22X also have a third register CHRG_CTRL3 which has settings for
battery charging too.

This adds the CHRG_CTRL1, CHRG_CTRL2 and CHRG_CTRL3 registers to the
list of writeable registers for AXP20X and AXP22X PMICs.

This is a sucky change to bump up the time we'll wait for the EC.  Why
is it sucky?  If 200ms for a transfer is a common thing it will have a
massively bad impact on keyboard responsiveness.

It still seems like a good idea to do this, though, because we have a
gas gauge that claims that in an extreme case it could stretch the i2c
clock for 144ms.  It's not a common case so it shouldn't affect
responsiveness, but it can happen.  It's much better to have a single
slow keyboard response than to start returning errors when we don't
have to.

In newer EC designs we should probably implement a virtual battery to
respond to the kernel to insulate the kernel from these types of
issues.

TI LMU (Lighting Management Unit) driver supports lighting devices below.

  LM3532, LM3631, LM3632, LM3633, LM3695 and LM3697.

LMU devices have common features.
  - I2C interface for accessing device registers
  - Hardware enable pin control
  - Backlight brightness control
  - Notifier for hardware fault monitoring
  - Regulators for LCD display bias

It contains fault monitor, backlight, LED and regulator driver.

LMU fault monitor
-----------------
  LM3633 and LM3697 provide hardware monitoring feature.
  It enables open or short circuit detection.
  After monitoring is done, each device should be re-initialized.
  Notifier is used for this case.
  Separate patch for 'ti-lmu-fault-monitor' will be sent later.

Backlight
---------
  It's handled by TI LMU backlight consolidated driver and
  chip dependent data. Separate patchset will be sent later.

LED indicator
-------------
  LM3633 has 6 indicator LEDs. Programmable dimming pattern is also
  supported. Separate patch for 'leds-lm3633' will be sent later.

Regulator
---------
  LM3631 has 5 regulators for the display bias.
  LM3632 supports 3 regulators. One consolidated driver enables it.
  The lm363x regulator driver is already upstreamed.

commit b101829a029a ("mfd: axp20x: Fix AXP806 access errors on cold boot")
was intended to fix the case where a board uses an AXP806 in slave mode,
but the boot loader leaves it in master mode for lack of AXP806 support.
But now the driver breaks on boards where the PMIC is operating in master
mode. This patch lets the driver use the new device tree property
"xpowers,master-mode" to set the correct operating mode for the board.
