Subject: [PATCH 7/8] fbdev: sm712fb: fix support for 1024x768-16 mode.
Date: Sat, 16 Mar 2019 22:25:03 +0000 [thread overview]
Message-ID: <20190316222504.27170-8-tomli@tomli.me> (raw)
In-Reply-To: <20190316222504.27170-1-tomli@tomli.me>
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.
