It also supports reading it from a NVMEM provider. But the latter is only possible for platform devices, because only platform devices are searched for a matching device node. Add a second method to fetch the NVMEM cell by a device tree node instead of a "struct device". Moreover, the NVMEM subsystem will return dynamically allocated data which has to be freed after use. Currently, this is handled by allocating a device resource manged buffer to store the MAC address. of_get_mac_address() then returns a pointer to this buffer. Without a device, this trick is not possible anymore. Thus, change the of_get_mac_address() API to have the caller supply a buffer. It was considered to use the network device to attach the buffer to, but then the order matters and netdev_register() has to be called before of_get_mac_address(). No driver does it this way. changes since v1: - fixed stmmac_probe_config_dt() for !CONFIG_OF - added missing queue in patch subject Michael Walle (2): of: net: pass the dst buffer to of_get_mac_address() of: net: fix of_get_mac_addr_nvmem() for PCI and DSA nodes arch/arm/mach-mvebu/kirkwood.c | 3 +- arch/powerpc/sysdev/tsi108_dev.c | 5 +- drivers/net/ethernet/aeroflex/greth.c | 6 +- drivers/net/ethernet/allwinner/sun4i-emac.c | 10 +-- drivers/net/ethernet/altera/altera_tse_main.c | 7 +- drivers/net/ethernet/arc/emac_main.c | 8 +- drivers/net/ethernet/atheros/ag71xx.c | 7 +- drivers/net/ethernet/broadcom/bcm4908_enet.c | 7 +- drivers/net/ethernet/broadcom/bcmsysport.c | 7 +- drivers/net/ethernet/broadcom/bgmac-bcma.c | 10 +-- .../net/ethernet/broadcom/bgmac-platform.c | 11 ++- drivers/net/ethernet/cadence/macb_main.c | 11 +-- .../net/ethernet/cavium/octeon/octeon_mgmt.c | 8 +- .../net/ethernet/cavium/thunder/thunder_bgx.c | 5 +- drivers/net/ethernet/davicom/dm9000.c | 10 +-- drivers/net/ethernet/ethoc.c | 6 +- drivers/net/ethernet/ezchip/nps_enet.c | 7 +- drivers/net/ethernet/freescale/fec_main.c | 7 +- drivers/net/ethernet/freescale/fec_mpc52xx.c | 7 +- drivers/net/ethernet/freescale/fman/mac.c | 9 +- .../ethernet/freescale/fs_enet/fs_enet-main.c | 5 +- drivers/net/ethernet/freescale/gianfar.c | 8 +- drivers/net/ethernet/freescale/ucc_geth.c | 5 +- drivers/net/ethernet/hisilicon/hisi_femac.c | 7 +- drivers/net/ethernet/hisilicon/hix5hd2_gmac.c | 7 +- drivers/net/ethernet/lantiq_xrx200.c | 7 +- drivers/net/ethernet/marvell/mv643xx_eth.c | 5 +- drivers/net/ethernet/marvell/mvneta.c | 6 +- .../ethernet/marvell/prestera/prestera_main.c | 11 +-- drivers/net/ethernet/marvell/pxa168_eth.c | 9 +- drivers/net/ethernet/marvell/sky2.c | 8 +- drivers/net/ethernet/mediatek/mtk_eth_soc.c | 11 +-- drivers/net/ethernet/micrel/ks8851_common.c | 7 +- drivers/net/ethernet/microchip/lan743x_main.c | 5 +- drivers/net/ethernet/nxp/lpc_eth.c | 4 +- drivers/net/ethernet/qualcomm/qca_spi.c | 10 +-- drivers/net/ethernet/qualcomm/qca_uart.c | 9 +- drivers/net/ethernet/renesas/ravb_main.c | 12 +-- drivers/net/ethernet/renesas/sh_eth.c | 5 +- .../ethernet/samsung/sxgbe/sxgbe_platform.c | 13 +-- drivers/net/ethernet/socionext/sni_ave.c | 10 +-- .../ethernet/stmicro/stmmac/dwmac-anarion.c | 2 +- .../stmicro/stmmac/dwmac-dwc-qos-eth.c | 2 +- .../ethernet/stmicro/stmmac/dwmac-generic.c | 2 +- .../net/ethernet/stmicro/stmmac/dwmac-imx.c | 2 +- .../stmicro/stmmac/dwmac-intel-plat.c | 2 +- .../ethernet/stmicro/stmmac/dwmac-ipq806x.c | 2 +- .../ethernet/stmicro/stmmac/dwmac-lpc18xx.c | 2 +- .../ethernet/stmicro/stmmac/dwmac-mediatek.c | 2 +- .../net/ethernet/stmicro/stmmac/dwmac-meson.c | 2 +- .../ethernet/stmicro/stmmac/dwmac-meson8b.c | 2 +- .../net/ethernet/stmicro/stmmac/dwmac-oxnas.c | 2 +- .../stmicro/stmmac/dwmac-qcom-ethqos.c | 2 +- .../net/ethernet/stmicro/stmmac/dwmac-rk.c | 2 +- .../ethernet/stmicro/stmmac/dwmac-socfpga.c | 2 +- .../net/ethernet/stmicro/stmmac/dwmac-sti.c | 2 +- .../net/ethernet/stmicro/stmmac/dwmac-stm32.c | 2 +- .../net/ethernet/stmicro/stmmac/dwmac-sun8i.c | 2 +- .../net/ethernet/stmicro/stmmac/dwmac-sunxi.c | 2 +- .../ethernet/stmicro/stmmac/dwmac-visconti.c | 2 +- drivers/net/ethernet/stmicro/stmmac/stmmac.h | 2 +- .../net/ethernet/stmicro/stmmac/stmmac_main.c | 4 +- .../ethernet/stmicro/stmmac/stmmac_platform.c | 14 +-- .../ethernet/stmicro/stmmac/stmmac_platform.h | 2 +- drivers/net/ethernet/ti/am65-cpsw-nuss.c | 19 ++--- drivers/net/ethernet/ti/cpsw.c | 7 +- drivers/net/ethernet/ti/cpsw_new.c | 7 +- drivers/net/ethernet/ti/davinci_emac.c | 8 +- drivers/net/ethernet/ti/netcp_core.c | 7 +- drivers/net/ethernet/wiznet/w5100-spi.c | 8 +- drivers/net/ethernet/wiznet/w5100.c | 2 +- drivers/net/ethernet/xilinx/ll_temac_main.c | 6 +- .../net/ethernet/xilinx/xilinx_axienet_main.c | 11 +-- drivers/net/ethernet/xilinx/xilinx_emaclite.c | 8 +- drivers/net/wireless/ath/ath9k/init.c | 5 +- drivers/net/wireless/mediatek/mt76/eeprom.c | 9 +- .../net/wireless/ralink/rt2x00/rt2x00dev.c | 6 +- drivers/of/of_net.c | 85 ++++++++++++------- drivers/staging/octeon/ethernet.c | 10 +-- drivers/staging/wfx/main.c | 7 +- include/linux/of_net.h | 6 +- include/net/dsa.h | 2 +- net/dsa/dsa2.c | 2 +- net/dsa/slave.c | 2 +- net/ethernet/eth.c | 11 +-- 85 files changed, 241 insertions(+), 362 deletions(-)
