From 28ce677fa7402a2d59033012a76cbfa1b4b9b868 Mon Sep 17 00:00:00 2001 From: Chukun Pan Date: Thu, 6 Apr 2023 20:21:03 +0800 Subject: [PATCH] generic: update nvmem cell mac-address-ascii support Instead of use mac-address-ascii in nvmem_get_mac_address function, move it into of_get_mac_addr_nvmem function to support more devices.
