From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nishanth Menon Subject: [PATCH 2/6] dt-bindings: serial: 8250_omap: Add compatible for J721E UART controller Date: Wed, 22 May 2019 11:19:17 -0500 Message-ID: <20190522161921.20750-3-nm@ti.com> References: <20190522161921.20750-1-nm@ti.com> Mime-Version: 1.0 Content-Type: text/plain Content-Transfer-Encoding: 8bit Return-path: In-Reply-To: <20190522161921.20750-1-nm@ti.com> Sender: linux-kernel-owner@vger.kernel.org To: Arnd Bergmann , Olof Johansson , Santosh Shilimkar , Will Deacon , Catalin Marinas , Greg Kroah-Hartman , Mark Rutland , Rob Herring Cc: linux-serial@vger.kernel.org, linux-kernel@vger.kernel.org, devicetree@vger.kernel.org, linux-arm-kernel@lists.infradead.org, Tony Lindgren , Russell King , Tero Kristo , Nishanth Menon , Sekhar Nori , Vignesh R List-Id: linux-serial@vger.kernel.org J721e uses a UART controller that is compatible with AM654 UART. Introduce a specific compatible to help handle the differences if necessary. Cc: Sekhar Nori Cc: Vignesh R Signed-off-by: Nishanth Menon --- NOTE: - If Greg is ok, we can pick up the uart compatibility via the k3 tree, else, I can spawn it off the series into it's own patch, but it seemed better in a logical order.
