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. Fixes: FS#2753 Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> Tested-by: Armin Fuerst <armin@fuerst.priv.at>
