Date: Tue, 4 Dec 2018 11:50:05 +0100 Message-Id: <20181204103731.625565469@linuxfoundation.org> In-Reply-To: <20181204103726.750894136@linuxfoundation.org> References: <20181204103726.750894136@linuxfoundation.org> MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Sender: linux-kernel-owner@vger.kernel.org List-ID: 4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Christoph Muellner commit c1d91f86a1b4c9c05854d59c6a0abd5d0f75b849 upstream. This patch fixes the wrong polarity setting for the PCIe host driver's pre-reset pin for rk3399-puma-haikou. Without this patch link training will most likely fail.
