From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Philip, Avinash" Subject: [PATCH v2 10/10] ARM: dts: AM33XX: Add PWM backlight DT data to am335x-evm Date: Thu, 8 Nov 2012 13:23:17 +0530 Message-ID: <1352361197-27442-11-git-send-email-avinashphilip@ti.com> References: <1352361197-27442-1-git-send-email-avinashphilip@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: In-Reply-To: <1352361197-27442-1-git-send-email-avinashphilip@ti.com> Sender: linux-omap-owner@vger.kernel.org To: thierry.reding@avionic-design.de, paul@pwsan.com, tony@atomide.com, linux@arm.linux.org.uk, b-cousson@ti.com Cc: hvaibhav@ti.com, anilkumar@ti.com, linux-kernel@vger.kernel.org, devicetree-discuss@lists.ozlabs.org, linux-doc@vger.kernel.org, linux-omap@vger.kernel.org, linux-arm-kernel@lists.infradead.org, nsekhar@ti.com, gururaja.hebbar@ti.com, vaibhav.bedia@ti.com, "Philip, Avinash" List-Id: devicetree@vger.kernel.org PWM output from ecap0 uses as backlight source. Also adds low threshold value to have a uniform divisions in brightness-levels scales. Signed-off-by: Philip, Avinash --- :100644 100644 185d632... 9857050...
