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

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

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 2/4] ARM: dts: imx7d-sdb: Pass phy-reset-gpios

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

Pass the phy-reset-gpios property so that Ethernet PHYs can go
through a proper reset.

[PATCH 3/4] ARM: imx_v6_v7_defconfig: Enable SPI_GPIO

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

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

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

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.
