Subject: [PATCH RESEND 2/3] drm: adv7511: mark ADV7511_REG_EDID_READ_CTRL volatile
Date: Mon, 04 Jan 2016 02:33:46 +0000	[thread overview]
Message-ID: <1451874827-2531-2-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1451874827-2531-1-git-send-email-wsa@the-dreams.de>

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

This register includes a counter which is decremented by the chip on I2C
failures. Also, it is reset when powering down.
