I am sorry multiple drivers had regressed due the original patches. I haven't been tracking the mailing lists actively past few weeks, and only came across this when Laurent mentioned a patch from the v3 of this series a couple days back in a discussion for the Rockchip drivers. My email-id that is indeed used in all those conversations is long gone, and I had hoped having the newer email-id in the sign-off-by tags would make up for it. Perhaps that wasn't the case. I am a little late, but I did give a look at the v6. I don't for-see any concerns with it. -- Regards Aradhya _______________________________________________ Linux-rockchip mailing list Linux-rockchip@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-rockchip From mboxrd@z Thu Jan 1 00:00:00 1970 Received: from out-186.mta1.migadu.com (out-186.mta1.migadu.com [95.215.58.186]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by smtp.subspace.kernel.org (Postfix) with ESMTPS id 3E2DC19D8AC for ; Thu, 4 Dec 2025 15:16:16 +0000 (UTC) Authentication-Results: smtp.subspace.kernel.org; arc=none smtp.client-ip=95.215.58.186 ARC-Seal:i=1; a=rsa-sha256; d=subspace.kernel.org; s=arc-20240116; t=1764861379; cv=none; b=RM3PStqxXNmBd7/KsrDUZENpZMyrIneFL3p3D/4etix27fNwDbkr7K4w48l6Tv7EuJ9T2hM0gzVGqoZY+3KsnS9uYnE6dgSUr+ugb4Joq+crMeO/np+5zbiodJydIQtyvnr2e6mL8vLpRpin5dt8OWGdZn15RdGb2ZhvidvShCQ= ARC-Message-Signature:i=1; a=rsa-sha256; d=subspace.kernel.org; s=arc-20240116; t=1764861379; c=relaxed/simple; bh=qjOIvShGhmLljPUFevXVcg8QRdXTO63XF54qsgX6o3k=; h=Message-ID:Date:MIME-Version:Subject:To:Cc:References:From: In-Reply-To:Content-Type; b=ldTGrIn1tGVD3Tm8+ks5CaEPFRgGkosa6BMtylv6JBk22TKPvBrjonBHyVtgIwiC+qjvIqzY9DysgSiKQIWYM3QPlibgxBSTLAuZKa1icY2hWUpOLKyGrbZpogE+pXCKHoQOAVMdrxTHMDXUGpB2lg6igwRQ/0dxgG97/j78Tp4= ARC-Authentication-Results:i=1; smtp.subspace.kernel.org; dmarc=pass (p=none dis=none) header.from=linux.dev; spf=pass smtp.mailfrom=linux.dev; dkim=pass (1024-bit key) header.d=linux.dev header.i=@linux.dev header.b=Muw99Q3o; arc=none smtp.client-ip=95.215.58.186 Authentication-Results: smtp.subspace.kernel.org; dmarc=pass (p=none dis=none) header.from=linux.dev Authentication-Results: smtp.subspace.kernel.org; spf=pass smtp.mailfrom=linux.dev Authentication-Results: smtp.subspace.kernel.org; dkim=pass (1024-bit key) header.d=linux.dev header.i=@linux.dev header.b="Muw99Q3o" Message-ID: <369afee2-2ae9-4dee-ab0c-c9f196c8dbb1@linux.dev> DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=linux.dev; s=key1; t=1764861375; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=C1WFKmJAqdQOsrn5LBL7ihECviyJrkF8uPSQqPQKLmw=; b=Muw99Q3oLkmh1GuLJgjVocivZRtHEuRhrWoQoFNBg0w4a3Ls2dUzsY7oeA/sGkzfk9x3ql HrtQbATnA74HAQFpZw+uAFrZra1Kaj8/4p6+YtXR4BXBkjUMgBsT7oHR7gUXN/KZ47a8OP wwl5iU0UrWDxHndsG6QlPgaGmCldnBI= Date: Thu, 4 Dec 2025 15:16:10 +0000 Precedence: bulk X-Mailing-List: linux-renesas-soc@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Subject: Re: [PATCH v6 0/4] drm/atomic-helpers: Fix MCDE/R-Car DU regressions To: Linus Walleij , Vicente Bergas , Tomi Valkeinen , Marek Vasut , Maarten Lankhorst , Maxime Ripard , Thomas Zimmermann , David Airlie , Simona Vetter , Laurent Pinchart , Tomi Valkeinen , Kieran Bingham , Geert Uytterhoeven , Magnus Damm , Aradhya Bhatia , Dmitry Baryshkov , Linus Walleij , Sandy Huang , =?UTF-8?Q?Heiko_St=C3=BCbner?= , Andy Yan Cc: dri-devel@lists.freedesktop.org, linux-renesas-soc@vger.kernel.org, linux-rockchip@lists.infradead.org, Geert Uytterhoeven References: <20251202-mcde-drm-regression-thirdfix-v6-0-f1bffd4ec0fa@kernel.org> Content-Language: en-US X-Report-Abuse: Please report any abuse attempt to abuse@migadu.com and include these headers.
