This patchset provides different fixes to the rpi-panel-attiny-regulator driver.

This is a preparation patchset for supporting the official Raspberry Pi 7
inches touchscreen.

It has been tested with a Raspberry Pi 4 B and the official Raspberry Pi 7
inches touchscreen.

Changes in v2:
 * Add a dependency on OF_GPIO for GPIO controlled resets

Changes in v3:
 * Add Signed-off-bys
 * Use the regmap cache

Dave Stevenson (9):
  regulator: rpi-panel: Register with a unique backlight name
  regulator: rpi-panel: Handle I2C errors/timing to the Atmel
  regulator: rpi-panel: Serialise operations.
  regulator: rpi-panel: Ensure the backlight is off during probe.
  regulator: rpi-panel: Convert to drive lines directly
  regulator: rpi-panel: Add GPIO control for panel and touch resets
  regulator: rpi-panel: Remove get_brightness hook
  regulator/rpi-panel-attiny: Use the regmap cache
  regulator/rpi-panel-attiny: Use two transactions for I2C read

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
