So, samsung-dsim (bridge) must not be in display mode during the prepare()/unprepare() of the panel-bridge. Setting the "pre_enable_prev_first" flag to true allows the prepare() of the panel-bridge to be called between the pre_enabled() and enabled() of the bridge. So, the bridge can enter display mode only in the enabled(). The unprepare() of the panel-bridge is instead called between the disable() and post_disable() of the bridge. So, the disable() must exit the display mode (i .e. enter command mode) to allow the panel-bridge to receive DSI commands. samsung_dsim_atomic_pre_enable -> command mode r63353_panel_prepare -> send DSI commands samsung_dsim_atomic_enable -> enter display mode samsung_dsim_atomic_disable -> exit display mode (command mode) r63353_panel_unprepare -> send DSI commands samsung_dsim_atomic_post_disable Co-developed-by: Michael Trimarchi Signed-off-by: Michael Trimarchi Signed-off-by: Dario Binacchi --- (no changes since v1) drivers/gpu/drm/bridge/samsung-dsim.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/bridge/samsung-dsim.c b/drivers/gpu/drm/bridge/samsung-dsim.c index be5914caa17d..15bf05b2bbe4 100644 --- a/drivers/gpu/drm/bridge/samsung-dsim.c +++ b/drivers/gpu/drm/bridge/samsung-dsim.c @@ -1494,7 +1494,6 @@ static void samsung_dsim_atomic_pre_enable(struct drm_bridge *bridge, return; samsung_dsim_set_display_mode(dsi); - samsung_dsim_set_display_enable(dsi, true); } } @@ -1507,6 +1506,7 @@ static void samsung_dsim_atomic_enable(struct drm_bridge *bridge, samsung_dsim_set_display_mode(dsi); samsung_dsim_set_display_enable(dsi, true); } else { + samsung_dsim_set_display_enable(dsi, true); samsung_dsim_set_stop_state(dsi, false); } @@ -1524,6 +1524,8 @@ static void samsung_dsim_atomic_disable(struct drm_bridge *bridge, if (!samsung_dsim_hw_is_exynos(dsi->plat_data->hw_type)) samsung_dsim_set_stop_state(dsi, true); + samsung_dsim_set_display_enable(dsi, false); + dsi->state &= ~DSIM_STATE_VIDOUT_AVAILABLE; } @@ -1532,7 +1534,8 @@ static void samsung_dsim_atomic_post_disable(struct drm_bridge *bridge, { struct samsung_dsim *dsi = bridge_to_dsi(bridge); - samsung_dsim_set_display_enable(dsi, false); + if (!samsung_dsim_hw_is_exynos(dsi->plat_data->hw_type)) + samsung_dsim_set_stop_state(dsi, true); dsi->state &= ~DSIM_STATE_ENABLED; pm_runtime_put_sync(dsi->dev); From patchwork Mon Dec 18 08:43:38 2023 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit X-Patchwork-Submitter: Dario Binacchi X-Patchwork-Id: 180208 Return-Path: Delivered-To: ouuuleilei@gmail.com Received: by 2002:a05:7300:24d3:b0:fb:cd0c:d3e with SMTP id r19csp1106693dyi; Mon, 18 Dec 2023 00:45:35 -0800 (PST) X-Google-Smtp-Source: AGHT+IHPEuoT6BhwfUP4XiUznBRqQwUrxegjcKce45qRBzRcgFan1X6v1vz/5GHjE/JotvyhDGg2 X-Received: by 2002:a05:6359:5e15:b0:170:2955:8747 with SMTP id pw21-20020a0563595e1500b0017029558747mr13484680rwb.54.1702889135398; Mon, 18 Dec 2023 00:45:35 -0800 (PST) ARC-Seal: i=1; a=rsa-sha256; t=1702889135; cv=none; d=google.com; s=arc-20160816; b=zHxvS6lVngeGiKgR6/0Ty760JdD42kCpi0/7dBlgmV8PA4ZJVgBdwQ5MNZorDutwaY 5jpbDYD+cCgRWRZmh4UB1nDjHtIrrX4pG47TH3M46Zm4+pxyvUl6pkWMiJ6SXQNGhwcy ReXV+gpFGHuyln82svbMuKXrupMarnCa4671YG05zBvARlAC5EDjjzD36bIcneWUzaHw cvbaamhRrGOJk1vehR+oyqw++0JGfjyDGy2WH9TwPC+Sb17z6mHMKxSZOWM3NAXV9dTy tjXyVBJTL7HvBUbSqe5pNOb6TNlZVTmaumvM9fDqZ02r4k8wj7x5+FzAArIc/qf8YItK 6ZCQ== ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=google.com; s=arc-20160816; h=content-transfer-encoding:mime-version:list-unsubscribe :list-subscribe:list-id:precedence:references:in-reply-to:message-id :date:subject:cc:to:from:dkim-signature; bh=vUOsBiPuxBvM6FDZ7VmJ/JCXXnby3Q2ff55p54IAZ7U=; fh=UPLugLp3TGz/UFnnpIyweeCZZjgZZPvHfi+TCy9TH+Y=; b=y21zdfWtpACVW5OM3r+hVd1+cbC3oS7UvhmPmC0u2BC4XgNcCF3HguGMFhQb16Tszn vIfWGPXcWjCv4T3NiSRW43jqx+dgVXt2fDwwAcOHXYVPCwK9fFD3Fw3tQ5ikLeSTTWDr ZgrM6K3wFple5H2mtGWSh9BwjKOQGxjZ+LXHavO9ts06eV3bSD4u90ki4KdvB7djdFWm I3VHfxn5gjybsTzoRu0TcOnW7CJbGzHZMLud+3rm9jiy0MMl3ZPZkU+73n7KD/Q1IelU vgD3YD8CyH700TlFeccXwEe4Xkh7uHt4QXbBXRvn6K/zCkErUxC1lu+mW8V5rrDjpi8U 9saw== ARC-Authentication-Results: i=1; mx.google.com; dkim=pass header.i=@amarulasolutions.com header.s=google header.b=OhMDcrAE; spf=pass (google.com: domain of linux-kernel+bounces-3183-ouuuleilei=gmail.com@vger.kernel.org designates 147.75.48.161 as permitted sender) smtp.mailfrom="linux-kernel+bounces-3183-ouuuleilei=gmail.com@vger.kernel.org"; dmarc=pass (p=NONE sp=NONE dis=NONE) header.from=amarulasolutions.com Received: from sy.mirrors.kernel.org (sy.mirrors.kernel.org.
