From 075a5b3969becb1ebc2f1d4fa1a1fe9163679273 Mon Sep 17 00:00:00 2001 From: Andy Yan Date: Mon, 11 Dec 2023 19:58:15 +0800 Subject: [PATCH] drm/rockchip: vop2: set bg dly and prescan dly at vop2_post_config We need to setup background delay cycle and prescan delay cycle when a mode is enable to avoid trigger POST_BUF_EMPTY irq on rk3588. Note: RK356x has no such requirement.
