From 18c95c9d6ebea5cef1254ee917bff8aba993666d Mon Sep 17 00:00:00 2001 From: Adrian Schmutzler Date: Thu, 30 Jan 2020 14:59:25 +0100 Subject: [PATCH] ath79: add gpio4 pinmux on TL-WR841N/ND v8, WR842N v2, MR3420 v2 This adds a pinmux to the shared DTSI for TP-Link TL-WR841N/ND v8, TL-WR842N v2 and TL-MR3420 v2. It is supposed to be the equivalent of: /* config gpio4 as normal gpio function */ ath79_gpio_output_select(TL_MR3420V2_GPIO_USB_POWER,AR934X_GPIO_OUT_GPIO); This allows to enable USB power on these devices. While at it, move the jtag_disable_pins to &gpio node and remove the redundant status=okay there. Tested on TP-Link TL-WR842N v2.
