Subject: [PATCH] MIPS: BCM47XX: Add support for Netgear R6200 V1
Date: Mon, 17 Jun 2019 00:26:46 -0500	[thread overview]
Message-ID: <6e003471-e7bd-6e0a-c00c-7de5e1b01428@gmail.com> (raw)

The Netgear R6200 v1 uses a BCM4718A1 SOC and a BCM4352/BCM4360 for 5GHz wireless.
This patch adds support for detecting this model board and registers the 3 buttons.
I have tested that the device can boot kernels 4.14 and 4.19 under OpenWRT.

There is one issue that the LEDs on the device are controlled by a 74HC164 that uses bit-banging instead of SPI so it isn't accessible to the kernel without adding a workaround.
Without any workaround the device on boot will flash all LEDs once then the power LED will remain amber as all other LEDs stay off.

I placed my change in board.c in that location because in OpenWRT it would be above the R6300 V1 in one of their patches.
