+From 8ea13a43a77dfb45c836de2d6c747f630dd75275 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] dtoverlays: Add support for ADV7280-M, ADV7281-M and
+ ADV7281-MA chips.
+
+The driver that supports the ADV7282-M also supports the ADV7280-M,
+ADV7281-M, and ADV7281-MA.
+The 7280-M exposes 8 analogue inputs. The 7281-M doesn't have the
+I2P deinterlacing block. The 7281-MA has 8 inputs but no I2P.
+Otherwise they are the same as ADV7282-M.
+
+Adds a new overlay "adv728x" that includes the existing adv7282
+overlay but adds several parameters to modify the behaviour.
+
+Adds a new addr parameter to allow the I2C address to be changed.
+(the chip has an address select pin to change between 0x20 and 0x21).
+
