Hi Linus, Alex,
This patch series contains two improvements to the 74x164 GPIO driver.
It was tested with 2 daisy-chained 74HC595 shift registers, connected to
a Renesas MSIOF SPI master, which cannot keep its hardware chip select
asserted in between multiple transfers without using cs-gpios.
Thanks!
Geert Uytterhoeven (2):
gpio: 74x164: Allocate buffer with gen_74x164_chip
gpio: 74x164: Use a single SPI transfer instead of multiple transfers
