From ad0258940f806c076f375eb41ed1d6c4a2a13f35 Mon Sep 17 00:00:00 2001 From: Bill XIE Date: Tue, 4 Apr 2023 10:02:39 +0800 Subject: [PATCH] mb/lenovo/x200/blc: Add LTN121AT07-L02 at 750Hz Its EDID string is "LTN121AT07L02". The vendor sets BLC_PWM_CTL to 0x31313131. This frequency seems working well on the x200 with this panel, which is said to be LED.
