From 5f610ec4b80b3d20e63f6600a9c8810ce975df19 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sat, 29 Aug 2020 23:23:32 +0200 Subject: [PATCH] bcm53xx: backport uart2 and pcie2 device-nodes These have made their way into -next. This patch also includes the portion of the bcm53xx kernel patch refreshes as the hunks in 302-ARM-dts-BCM5301X-Update-Northstar-pinctrl-binding.patch moved slightly due to the added nodes.
