Date: Sun, 17 Mar 2019 06:25:03 +0800 Message-Id: <20190316222504.27170-8-tomli@tomli.me> X-Mailer: git-send-email 2.20.1 In-Reply-To: <20190316222504.27170-1-tomli@tomli.me> References: <20190316222504.27170-1-tomli@tomli.me> MIME-Version: 1.0 Sender: linux-fbdev-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-fbdev@vger.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP In order to support the 1024x600 panel on Yeeloong Loongson MIPS laptop, the original 1024x768-16 table was modified to 1024x600-16, without leaving the original. It causes problem on x86 laptop as the 1024x768-16 support was still claimed but not working. Fix it by introducing the 1024x768-16 mode.
