Our spio-gpio driver currently only supports 8bit word width. This series updates the driver to support arbitrary word widths up to 32bit. Also we get rid of the deprecated GPIO binding that the driver uses. Signed-off-by: Sascha Hauer <s.hauer@xxxxxxxxxxxxxx> --- Changes in v2: - use ndelay to implement spi_delay() - extract initial CS setting to extra patch - add patch to convert to gpiod API - update sandbox-libftdi-example.dtsi to use new GPIO binding - Link to v1: https://lore.barebox.org/20240925-spi-gpio-v1-0-47f6285b3bf1@xxxxxxxxxxxxxx --- Sascha Hauer (5): spi: spi-gpio: actually delay in spidelay() spi: spi-gpio: support different word widths spi: spi-gpio: switch to new gpio binding spi: spi-gpio: deassert CS during setup spi: spi-gpio: switch to gpiod api arch/arm/dts/stm32mp151-mect1s.dts | 6 +- arch/sandbox/dts/sandbox-libftdi-example.dtsi | 6 +- drivers/spi/gpio_spi.c | 181 +++++++++++++------------- include/spi/spi_gpio.h | 27 ---- 4 files changed, 95 insertions(+), 125 deletions(-) --- base-commit: 419ea9350aa083d4a2806a70132129a49a5ecf95 change-id: 20240925-spi-gpio-4e65be1f7b90 Best regards, -- Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>
