[U-Boot] [PATCH v2 0/5] DM: Convert i.MX28 gpio, pinmux, spi and eth drivers to DM/DTS

[Lukasz Majewski]

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

This patch series shall help with coordinated i.MX28 DM/DTS
conversion and avoidance of effort duplication.

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.

Changes in v2:
- Use #if !CONFIG_IS_ENABLED(DM_GPIO) instead of plain #ifdef CONFIG_DM_GPIO
- New patch (conversion of mxs_spi.c to DM_SPI)
