From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Horman Date: Fri, 20 Nov 2015 01:05:28 +0000 Subject: [PATCH 21/29] ARM: shmobile: r8a7794: alt: Enable VGA port Message-Id: <876e7fb9f418fd86719af345febf8656c47e833c.1447981420.git.horms+renesas@verge.net.au> List-Id: References: In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-arm-kernel@lists.infradead.org From: Magnus Damm Enable the DU device and the VGA port available on the r8a7794 ALT board. The VGA portion of the ALT board is somewhat similar to the Lager board but in case of ALT the DU1 pins are used and the X2 clock has a reduced frequency. This patch does not include any pinctrl (PFC) settings due to lack of PFC DT integration on r8a7794. At this point the default state of the boot loader is enough to keep the VGA port working without changing any pinctrl settings.
