I read the Toppoly datasheet and it seems, the LCD panel implements V/HSYNC, while Samsung does not (and I'm sure at least one of these sync pins must be GPIO for DC-DC control). A solution is probably to reconfigure the GPIO muxes by detected LCD type. > > best regards > Philipp > Petr From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S1752044AbbJECO6 (ORCPT ); Sun, 4 Oct 2015 22:14:58 -0400 Received: from bubo.tul.cz ([147.230.16.1]:54993 "EHLO bubo.tul.cz" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751495AbbJECO5 (ORCPT ); Sun, 4 Oct 2015 22:14:57 -0400 Subject: Re: [PATCH v4 07/26] ARM: pxa: magician: Fix HTC Magician pin mux definitions To: Philipp Zabel , robert.jarzmik@free.fr, daniel@zonque.org, haojian.zhuang@gmail.com, linux@arm.linux.org.uk References: <5609ADF5.9070003@tul.cz> <1443875409.4186.20.camel@gmail.com> Cc: linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org From: Petr Cvek Message-ID: <5611DD36.5030108@tul.cz> Date: Mon, 5 Oct 2015 04:15:18 +0200 User-Agent: Mozilla/5.0 (X11; Linux i686; rv:38.0) Gecko/20100101 Thunderbird/38.2.0 MIME-Version: 1.0 In-Reply-To: <1443875409.4186.20.camel@gmail.com> Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Dne 3.10.2015 v 14:30 Philipp Zabel napsal(a): > Am Montag, den 28.09.2015, 23:15 +0200 schrieb Petr Cvek: >> This patch fixes a pin mux for the HTC Magician machine.
