[PATCH 0/7] sy7636a: power the panel only during updates

[Pablo Mazzini <pmazzini@gmail.com>]

The SY7636A hwmon driver keeps VCOM on from probe, so a display driver
can not power the panel only during updates.

Read the temperature in the regulator driver instead, as the TPS65185
and FP9931 drivers do, and remove the hwmon driver. Boards that relied
on VCOM staying on mark it always-on. The regulator also switches VCOM
with VCOM_EN, gains VCOM voltage control and binds to the I2C device
directly.

Tested on a PocketBook Verse (B288).

Pablo Mazzini (7):
  ARM: dts: imx: keep the SY7636A VCOM on
  regulator: sy7636a: fix the chip name
  regulator: sy7636a: add VCOM voltage control
  regulator: sy7636a: wait for power good, then switch VCOM_EN
  regulator: sy7636a: report the temperature
  regulator: sy7636a: bind to the I2C device directly
  ARM: imx_v6_v7_defconfig: drop the SY7636A MFD and hwmon options
