||
4 | Subject: [PATCH 409/454] dtoverlays: Add support for ADV7280-M, ADV7281-M and |
||
5 | ADV7281-MA chips. |
||
6 | |||
7 | The driver that supports the ADV7282-M also supports the ADV7280-M, |
||
8 | ADV7281-M, and ADV7281-MA. |
||
9 | The 7280-M exposes 8 analogue inputs. The 7281-M doesn't have the |
||
10 | I2P deinterlacing block. The 7281-MA has 8 inputs but no I2P. |
||
11 | Otherwise they are the same as ADV7282-M. |
||
12 | |||
13 | Adds a new overlay "adv728x" that includes the existing adv7282 |
||
14 | overlay but adds several parameters to modify the behaviour. |
||
15 | |||
16 | Adds a new addr parameter to allow the I2C address to be changed. |
||
17 | (the chip has an address select pin to change between 0x20 and 0x21). |
||
18 | |||
