[U-Boot] [PATCH v3 0/5] DM: Convert i.MX28 gpio, pinmux, spi and eth drivers to DM/DTS

16 Jun 2019


      This patch series converts some i.MX28 drivers to use DM/DTS.
Converted drivers:
- mxs_gpio.c - gpio driver
- pinctrl-mxs.c - pinmux driver
- Adjust fec_eth.c to support also i.MX28 SoC.
- mxs_spi.c - SPI driver
After applying this series it is possible to use ETH on i.MX28
board with following DTS description:
&mac0 {
    	phy-mode = "rmii";
    	pinctrl-names = "default";
    	pinctrl-0 = <&mac0_pins_a>;
    	phy-supply = <&reg_fec_3v3>;
    	phy-reset-gpios = <&gpio2 13 GPIO_ACTIVE_LOW>;
    	phy-reset-duration = <1>;
    	phy-reset-post-delay = <1>;
    	status = "okay";
fixed-link {
    	      speed = <100>;
    	      full-duplex;
    	};
};
And store the received binaries on SPI-NOR memory.
