This is a follow-up to a series I posted a while ago the goal of which was to replace the at24 platform data with device properties. To do so we need to somehow remove reading the MAC address from relevant board files. In my patches I used nvmem and MTD to read the MAC address from within the davinci emac driver. It was suggested that we generalize it further but since MTD doesn't support nvmem yet, the best we can do is to move this code over to net core code. The following patches modify the eth_platform_get_mac_address() function which seems to be the best candidate for this code. The first patch splits the function into two subroutines. The last two patches add nvmem and MTD support to the function. In order to stay compatible with existing users, nvmem and MTD will be tried last - after device tree and arch-specific callback. If this series gets accepted I will modify my previous patches to use it instead of handcoding the same operations in davinci_emac. v1 -> v2: - dropped patches 1 & 2 - improved the MAC address verification and fixed a potential buffer overflow in patch 2/3 v2 -> v3: - in patch 1: split the function into subroutines in preparation for nvmem and MTD support - modify patches 2 & 3 so that they have a separate function for each new MAC address source Bartosz Golaszewski (3): net: split eth_platform_get_mac_address() into subroutines net: add support for nvmem to eth_platform_get_mac_address() net: add MTD support to eth_platform_get_mac_address() net/ethernet/eth.c | 117 ++++++++++++++++++++++++++++++++++++++++----- 1 file changed, 106 insertions(+), 11 deletions(-) -- 2.17.1 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
