From: Jonas Gorski Date: Wed, 19 Dec 2018 23:05:15 +0000 (+0100) Subject: brcm63xx: fix bcm6348 pinmux group selection X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d09561f73d74c467347753a153c509faa48233a1;p=openwrt%2Fstaging%2Fthess.git brcm63xx: fix bcm6348 pinmux group selection The mask/shift computation used the pin group number instead of the pin number, resulting in always modifying group 4 when applying muxes, so fix it to consistently use the pin number.
