From: Christian Lamparter Date: Fri, 5 Nov 2021 21:50:45 +0000 (+0100) Subject: ath79: WNDR3700/3800/MAC: utilize nvmem for caldata fetching X-Git-Tag: v22.03.0-rc1~1284 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=217571b6abb3118a81e1cde32dd1151a9e95a0fc;p=openwrt%2Fopenwrt.git ath79: WNDR3700/3800/MAC: utilize nvmem for caldata fetching converts the still popular WNDR3700 Series to fetch the caldata through nvmem. As the "MAC with NVMEM" has shown, there could pitfalls along the way.
