[PATCH RESEND v2 0/2] pinctrl-meson: two small improvements

[Martin Blumenstingl <martin.blumenstingl@xxxxxxxxxxxxxx>]

While playing with audio output on Meson8b I found out that the
vendor kernel uses a custom version of the GPIO_PULL_UP flag. I
suspect that we will need this for audio support on Meson8b and/or
Meson8m2 but I don't see it hurt other platforms.

Also while comparing the register bits with the GPIO direction (of
GPIOs exported to sysfs) I sometimes had a mismatch. This also wires
up gpio_chip.get_direction to have sysfs and the actual registers in
sync.


Changes since v1 from [0]:
- re-send as non-"RFC" because I only got one comment in the past week
  for patch #2. Jerome pointed out an alternative way to GPIO_PULL_UP
  and GPIO_PULL_DOWN. However, this doesn't invalidate the patch, it
  just means that there are two ways to achieve the same goal.

  pinctrl: meson: implement the gpio_chip get_direction callback
