Subject: [PATCH v2 0/3] gpio: 74HC595 / 74x164 shift register improvements

This patchset adds a compatible string for another part, and clarifies
the role of the latch clock pin on 74x164-compatible shift registers.

Signed-off-by: J. Neuschäfer <j.ne@...teo.net>

Changes in v2:
- Remove patches 2 and 4 (latch GPIO support) in favor of a new patch 3,
  which explains that the latch GPIO acts as a chip select
- Add missing spi_device_id entry in the driver
- Add Linus Walleij's R-b tags
- Link to v1: https://lore.kernel.org/r/20241213-gpio74-v1-0-fa2c089caf41@posteo.net
