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). + +Signed-off-by: Dave Stevenson +--- + arch/arm/boot/dts/overlays/Makefile | 1 + + arch/arm/boot/dts/overlays/README | 13 +++++++ + .../boot/dts/overlays/adv7282m-overlay.dts | 9 +++-- + .../boot/dts/overlays/adv728x-m-overlay.dts | 37 +++++++++++++++++++ + 4 files changed, 56 insertions(+), 4 deletions(-) + create mode 100644 arch/arm/boot/dts/overlays/adv728x-m-overlay.dts + +--- a/arch/arm/boot/dts/overlays/Makefile ++++ b/arch/arm/boot/dts/overlays/Makefile +@@ -7,6 +7,7 @@ dtbo-$(CONFIG_ARCH_BCM2835) += \ + ads1115.dtbo \ + ads7846.dtbo \ + adv7282m.dtbo \ ++ adv728x-m.dtbo \ + akkordion-iqdacplus.dtbo \ + allo-boss-dac-pcm512x-audio.dtbo \ + allo-digione.dtbo \ +--- a/arch/arm/boot/dts/overlays/README ++++ b/arch/arm/boot/dts/overlays/README +@@ -274,6 +274,19 @@ Info: Analog Devices ADV7282M analogue + Load: dtoverlay=adv7282m,= + Params: i2c_pins_28_29 Use pins 28&29 for the I2C instead of 44&45. + This is required for Pi B+, 2, 0, and 0W. ++ addr Overrides the I2C address (default 0x21) ++ ++ ++Name: adv728x-m ++Info: Analog Devices ADV728[0|1|2]-M analogue video to CSI2 bridges. ++ This is a wrapper for adv7282m, and defaults to ADV7282M. ++Load: dtoverlay=adv728x-m,= ++Params: i2c_pins_28_29 Use pins 28&29 for the I2C instead of 44&45. ++ This is required for Pi B+, 2, 0, and 0W. ++ addr Overrides the I2C address (default 0x21) ++ adv7280m Select ADV7280-M. ++ adv7281m Select ADV7281-M. ++ adv7281ma Select ADV7281-MA. + + + Name: akkordion-iqdacplus +--- a/arch/arm/boot/dts/overlays/adv7282m-overlay.dts ++++ b/arch/arm/boot/dts/overlays/adv7282m-overlay.dts +@@ -13,13 +13,13 @@ + #size-cells = <0>; + status = "okay"; + +- adv7282: adv7282@21 { ++ adv728x: adv728x@21 { + compatible = "adi,adv7282-m"; + reg = <0x21>; + status = "okay"; + clock-frequency = <24000000>; + port { +- adv7282_0: endpoint { ++ adv728x_0: endpoint { + remote-endpoint = <&csi1_ep>; + clock-lanes = <0>; + data-lanes = <1>; +@@ -43,7 +43,7 @@ + #address-cells = <1>; + #size-cells = <0>; + csi1_ep: endpoint { +- remote-endpoint = <&adv7282_0>; ++ remote-endpoint = <&adv728x_0>; + }; + }; + }; +@@ -71,6 +71,7 @@ + }; + + __overrides__ { +- i2c_pins_28_29 = <0>,"+2-3"; ++ i2c_pins_28_29 = <0>,"+2-3"; ++ addr = <&adv728x>,"reg:0"; + }; + }; +--- /dev/null ++++ b/arch/arm/boot/dts/overlays/adv728x-m-overlay.dts +@@ -0,0 +1,37 @@ ++// SPDX-License-Identifier: GPL-2.0-only ++// Definitions for Analog Devices ADV728[0|1|2]-M video to CSI2 bridges on VC ++// I2C bus ++ ++#include "adv7282m-overlay.dts" ++ ++/{ ++ compatible = "brcm,bcm2708"; ++ ++ // Fragment numbers deliberately high to avoid conflicts with the ++ // included adv7282m overlay file. ++ ++ fragment@101 { ++ target = <&adv728x>; ++ __dormant__ { ++ compatible = "adi,adv7280-m"; ++ }; ++ }; ++ fragment@102 { ++ target = <&adv728x>; ++ __dormant__ { ++ compatible = "adi,adv7281-m"; ++ }; ++ }; ++ fragment@103 { ++ target = <&adv728x>; ++ __dormant__ { ++ compatible = "adi,adv7281-ma"; ++ }; ++ }; ++ ++ __overrides__ { ++ adv7280m = <0>, "+101"; ++ adv7281m = <0>, "+102"; ++ adv7281ma = <0>, "+103"; ++ }; ++}; -- cgit v1.2.3
