PATCH 1/4 ARM: dts: imx7d-sdb: Put pinctrl_spi4 in the correct location

From: Fabio Estevam <[email protected]>

pinctrl_spi4 pin group is not part of the low power iomux controller, so move it under the normal iomuxc node.

Fixes 184f39b57cab6 ("ARM: dts: imx7d-sdb: Add GPIO expander node")

PATCH 3/4 ARM: imx_v6_v7_defconfig: Enable SPI_GPIO

In reply to Fabio Estevam

From: Fabio Estevam <[email protected]>

Some boards like imx7d-sdb provide SPIO functionality via GPIOs, so enable the CONFIG_SPI_GPIO option.

PATCH 4/4 ARM: imx_v6_v7_defconfig: Enable GPIO_74X164

In reply to Fabio Estevam

From: Fabio Estevam <[email protected]>

imx7d-sabresd board uses a 74LV595PW SPI expander to drive several peripherals, such as Ethernet reset, PCI reset, LCD power, etc.

Enabled this option by default.
