+Subject: [PATCH] ARM: dts: BCM5301X: Specify flash partitions
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Most devices use Broadcom standard partitions which allows them to be
+described with the "brcm,bcm947xx-cfe-partitions". Exceptions are:
+1) TP-LINK devices which use "os-image" partition with TRX containing
+   kernel only + separated rootfs partition.
+2) Asus RT-AC87U with custom "asus" partition.
+
+This commit also removes undocumented and unsupported linux,part-probe
+binding which got accidentally upstreamed while describing SPI
+controller.
