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.
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 = <®_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; }; };
