VIO is likely a fixed regulator-always-on regulator for now. > board/dhelectronics/dh_imx6/dh_imx6.c | 26 +++++--------------------- > configs/dh_imx6_defconfig | 2 ++ > 2 files changed, 7 insertions(+), 21 deletions(-) > > diff --git a/board/dhelectronics/dh_imx6/dh_imx6.c b/board/dhelectronics/dh_imx6/dh_imx6.c > index 33ce7e8ff115..aafb9f1b341f 100644 > --- a/board/dhelectronics/dh_imx6/dh_imx6.c > +++ b/board/dhelectronics/dh_imx6/dh_imx6.c > @@ -28,10 +28,7 @@ > #include <fsl_esdhc_imx.h> > #include <fuse.h> > #include <i2c_eeprom.h> > -#include <miiphy.h> > #include <mmc.h> > -#include <net.h> > -#include <netdev.h> > #include <usb.h> > #include <usb/ehci-ci.h> > > @@ -80,31 +77,14 @@ static int setup_fec_clock(void) > return enable_fec_anatop_clock(0, ENET_50MHZ); > } > > -int board_eth_init(bd_t *bis) > +static void setup_fec(void) > { > - uint32_t base = IMX_FEC_BASE; > - struct mii_dev *bus = NULL; > - struct phy_device *phydev = NULL; > - > gpio_request(IMX_GPIO_NR(5, 0), "PHY-reset"); > gpio_request(IMX_GPIO_NR(1, 7), "VIO"); > > setup_fec_clock(); > > eth_phy_reset(); > - > - bus = fec_get_miibus(base, -1); > - if (!bus) > - return -EINVAL; > - > - /* Scan PHY 0 */ > - phydev = phy_find_by_mask(bus, 0xf, PHY_INTERFACE_MODE_RGMII); > - if (!phydev) { > - printf("Ethernet PHY not found!\n"); > - return -EINVAL; > - } > - > - return fec_probe(bis, -1, base, bus, phydev); > } > #endif > > @@ -190,6 +170,10 @@ int board_init(void) > > setup_dhcom_mac_from_fuse(); > > +#ifdef CONFIG_FEC_MXC You probably want to init the clock either way, not only if the FEC is enabled, so drop the ifdef. > + setup_fec(); > +#endif [...]

Use DM_ETH instead of legacy networking. Signed-off-by: Harald Seiler <hws at denx.de> --- Notes: I am unsure whether I converted 'enough' of the board_eth_init() function to DM. I think the reset GPIO in particular could be handled by the DM driver if I add the following to the device-tree (did not try it yet): phy-reset-gpios = <&gpio5 0 GPIO_ACTIVE_LOW>; phy-reset-duration = <1>; phy-reset-post-delay = <10>; Is it preferred to change the device-tree here or should I keep the reset from board_init() like I have it now? If I should use the dt, is there a similar way for dealing with VIO? board/dhelectronics/dh_imx6/dh_imx6.c | 26 +++++--------------------- configs/dh_imx6_defconfig | 2 ++ 2 files changed, 7 insertions(+), 21 deletions(-)
