Subject: [PATCH] ARM: dts: BCM5301X: Specify flash partitions
|
|
MIME-Version: 1.0

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.
