ARM: imx6: DHCOM i.MX6 PDK: Convert to DM_ETH Use DM_ETH instead of legacy networking. Add VIO as a fixed regulator to the relevant device-trees and augment the FEC node with properties for the reset GPIO. It should be noted that the relevant properties for the reset GPIO already exist in the PHY node (reset-gpios, reset-delay-us, reset-post-delay-us) but U-Boot currently ignores those and only supports the bus-level reset properties in the FEC node (phy-reset-gpios, phy-reset-duration, phy-reset-post-delay).

ARM: imx6: DHCOM i.MX6 PDK: Fix usb-otg VBUS regulator During the conversion of this board to DM_REGULATOR, usb-mass-storage was broken and started failing with the following error: => ums 0 mmc 2 UMS: LUN 0, dev 2, hwpart 0, sector 0x0, count 0xe90000 Error enabling VBUS supply g_dnl_register: failed!, error: -38 g_dnl_register failed Fix this by adding the relevant GPIO to the regulator node.
