From 0458a4428d2f7acc44a73f5cf417fa0e0e7d669b Mon Sep 17 00:00:00 2001 From: Mario Scheithauer Date: Fri, 26 Jan 2024 11:12:29 +0100 Subject: mb/siemens/mc_ehl5: Set LVDS re-power delay to 1 s The currently used panel type could work with 500 ms but increasing the value to 1 second allows to use a wider range of LVDS LCD panels, as many of them specify the delay of 1 s as minimum. The patch has already been made for mc_ehl3 and serves the purpose of standardization. commit c0221aa980d3 ("mb/siemens/mc_ehl3/lcd_panel.c: Set LVDS re-power delay to 1 s") Change-Id: Ife26ff27b41298ceeed7d9aed0c1ae5553ab5ff8 Signed-off-by: Mario Scheithauer Reviewed-on: https://review.coreboot.org/c/coreboot/+/80214 Tested-by: build bot (Jenkins) Reviewed-by: Jan Samek --- src/mainboard/siemens/mc_ehl/variants/mc_ehl5/lcd_panel.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/mainboard/siemens') diff --git a/src/mainboard/siemens/mc_ehl/variants/mc_ehl5/lcd_panel.c b/src/mainboard/siemens/mc_ehl/variants/mc_ehl5/lcd_panel.c index f3c5bd5608..0d189a34e2 100644 --- a/src/mainboard/siemens/mc_ehl/variants/mc_ehl5/lcd_panel.c +++ b/src/mainboard/siemens/mc_ehl/variants/mc_ehl5/lcd_panel.c @@ -82,8 +82,8 @@ enum cb_err mainboard_ptn3460_config(struct ptn_3460_config *cfg) cfg->t2_delay = 0x01; /* LVDS to backlight active delay: 200 ms */ cfg->t3_timing = 0x04; - /* Minimum re-power delay: 500 ms */ - cfg->t12_timing = 0x0a; + /* Minimum re-power delay: 1 s */ + cfg->t12_timing = 0x14; /* Backlight off to LVDS inactive delay: 200 ms */ cfg->t4_timing = 0x04; /* Enable LVDS to VDD inactive delay. */ -- cgit v1.2.3
