From: Michael Pratt Date: Sat, 1 May 2021 18:47:01 +0000 (-0400) Subject: ramips: mt7620: ethernet: use more macros and bump version X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=88a0cebadfecb6ebb9f5f535e74f7f7574f513f3;p=openwrt%2Fstaging%2Faparcar.git ramips: mt7620: ethernet: use more macros and bump version Define and use some missing macros, and use them instead of BIT() or numbers for more readable code. Add comment for a bit change that seems unrelated to ethernet but is actually needed (PCIe Root Complex mode). Remove unknown and unused macro RST_CTRL_MCM (probably from MT7621 / MT7622) This is the last of a series of fixes, so bump version.
