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 = <®_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.

Applied on top of u-boot/master branch SHA1: 77f6e2dd0551d8a825bab391a1bd6b838874bcd4
Changes in v5: - Add 12 digit SHA1 ID for tag v5.1.11 - Set more appropriate tags (net: fec:) - Use "ARM: dts: imx: tags" - Update tags ("gpio: mxs") - Set more appropriate tags ("pinctrl: mxs:") - Use the clrsetbits_le32() in mxs_pinctrl_rmwl() function - now moved to pinctrl-mxs.h file - Set more appropriate tags ("spi: mxs:")
Changes in v4: - Add 12 digit SHA1 ID for tag v5.1.9 - Sort the entries for compatibles and Kconfig - New file - imx28-u-boot.dtsi - Use BIT() macro instead of 1 << offset - Use devfdt_get_addr to get gpio number - Use gpio-ranges property to setup gpios - Use Linux kernel code to setup pins instead of Barebox - Add soc specific data and compatible for i.MX23 and i.MX28 - Use devm_kfree() to release temporary memory - Adjust the driver to support i.MX23 (add compatible, adjust clk code) - Use BIT() macro where applicable
Changes in v3: - Update tag to 5.1.9 - Set more apropriate tags - Set more appropriate tags - Set more appropriate tags - Set more appropriate tags - Set more appropriate tags
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)
