74bf7961a0 sunxi: axp152: dcdc3 scale is 50mV / step not 25mV / step
Currently uboot wrongly uses 25mV / step for dcdc3, this is a copy and paste
error introduced when adding the axp152_mvolt_to_target during review of the
axp152.c driver. This results in u-boot setting Vddr to 2.3V instead of 1.5V.

This commit fixes this.

Exynos 5250 boards (snow, spring) use the I2C driver but Exynos 5420 boards
cannot due to a hardware design decision. Select the correct driver to use

2c94611d5f cros_ec: power: Add a tunnelled version of the tps65090 driver
Unfortunately on Pit the AP has no direct access to the tps65090 but must
talk through the EC (over SPI) to the EC's I2C bus.

When driver model supports PMICs this will be relatively easy. In the
meantime the best approach is to duplicate the driver. It will be refactored
once driver model support is expanded.

676ac24e07 pmic: pmic_pfuze100: Use a shorter name for PMIC name
It is redundant to use 'PFUZE100_PMIC' as the PMIC name because we already
know it is a PMIC.

Call it simply 'PFUZE100' instead.

This adds driver support for the TPS65090 PMU. Support includes
hooking into the pmic infrastructure  so that the pmic commands
can be used on the console. The TPS65090 supports the following
functionality:

- fet enable/disable/querying
- getting and setting of charge state

Even though it is connected to the pmic infrastructure it does
not hook into the pmic charging charging infrastructure.

The device tree binding is from Linux, but only a small subset of
functionality is supported.

c9b0fa310c fuelgauge: max17042: fix i2c read issue which causes infinity loop.
Issues:
- reading i2c data by passing u16 pointer causes errors in read data.
- max17042 status register fields have not only Power On Reset meaning
  so using proper mask is required.

Changes:
- read i2c data to type u32 instead of u16 - avoids buffer overflow
- compare FG status register using mask not just one bit value
- add checking return value to functions fg read/write
- add model lock and model check count
- add debug msg

an twl6035 API, we could use an generic palmas API instead.

To stay consistent with the function naming of twl4030,6030 accessors,
we use palmas_i2c_[read|write]_u8
