Add the missing eth_rxd2 and eth_rxd3 definitions so we don't have to rely on the bootloader to set them up correctly. The vendor u-boot sources for Odroid-C1 use the following Ethernet pinmux configuration: SET_CBUS_REG_MASK(PERIPHS_PIN_MUX_6, 0x3f4f); SET_CBUS_REG_MASK(PERIPHS_PIN_MUX_7, 0xf00000); This translates to the following pin groups in the mainline kernel: - register 6 bit 0: eth_rxd1 (DIF_0_P) - register 6 bit 1: eth_rxd0 (DIF_0_N) - register 6 bit 2: eth_rx_dv (DIF_1_P) - register 6 bit 3: eth_rx_clk (DIF_1_N) - register 6 bit 6: eth_tx_en (DIF_3_P) - register 6 bit 8: eth_ref_clk (DIF_3_N) - register 6 bit 9: eth_mdc (DIF_4_P) - register 6 bit 10: eth_mdio_en (DIF_4_N) - register 6 bit 11: eth_tx_clk (GPIOH_9) - register 6 bit 12: eth_txd2 (GPIOH_8) - register 6 bit 13: eth_txd3 (GPIOH_7) - register 7 bit 20: eth_txd0_0 (GPIOH_6) - register 7 bit 21: eth_txd1_0 (GPIOH_5) - register 7 bit 22: eth_rxd3 (DIF_2_P) - register 7 bit 23: eth_rxd2 (DIF_2_N) All functions except eth_rxd2 and eth_rxd3 are already supported by the pinctrl-meson8b driver.
