Subject: arm64: dts: imx8mp-phyboard-pollux: Add and update rtc devicetree node
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7b4544849e0742d6f9b80e25804228c097c1edcc;p=linux.git

arm64: dts: imx8mp-phyboard-pollux: Add and update rtc devicetree node

The interrupt of the RTC is connected on the carrier board
phyBOARD-i.MX8MP-Pollux.

RTC trickle-charger devicetree property is dependent on the
phyboard-pollux design.
