From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christian Hewitt Subject: [PATCH v2] ARM64: dts: meson-gxbb-wetek: add ttyAML1 uart for Bluetooth Date: Fri, 7 Sep 2018 16:15:36 +0400 Message-ID: <1536322536-53109-1-git-send-email-christianshewitt@gmail.com> References: <1536072290-28015-1-git-send-email-christianshewitt@gmail.com> Return-path: In-Reply-To: <1536072290-28015-1-git-send-email-christianshewitt@gmail.com> Sender: linux-kernel-owner@vger.kernel.org Cc: narmstrong@baylibre.com, christianshewitt@gmail.com, martin.blumenstingl@googlemail.com, Rob Herring , Mark Rutland , Carlo Caione , Kevin Hilman , devicetree@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-amlogic@lists.infradead.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.org This change adds the uart_A used by the brmcfmac sdio module in the WeTek Hub and WeTek Play 2 devices. meson_uart_probe seems to mandate an alias (without it, BT is not working) so this is also included.
