From 42374b94d70cea72af94202ff5a467f036bc083e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Edward=20Matijevi=C4=87?= Date: Mon, 17 Jun 2019 00:26:46 -0500 Subject: [PATCH] MIPS: BCM47XX: Add support for Netgear R6200 V1 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.
