[PATCHv3 0/3] gpios: Add daisy-chaining and dt support to 74x164

[Maxime Ripard]

Hi all,

This is an attempt at adding the support for chained 8 bit shift registers that
are present in the cfa-10049.

This patchset also adds dt documentation to the 74x164 gpio driver.

Thanks,
Maxime

Changes since v2:
  * Fixed a memleak in the _write_config function when having an error.
