For example, it lets you say things like \"don't\nlet the channel 1 total exposure be more than 8x that of channel 0\",\nand so on. By using both an upper and lower bound constraint, you\ncould fix one AGC channel always to be a fixed ratio of another.\n\nAlso read a vector of them (if present) when loading the tuning file.\n\nSigned-off-by: David Plowman <david.plowman@raspberrypi.com>\nReviewed-by: Naushir Patuck <naush@raspberrypi.com>\nReviewed-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com>\n---\n src/ipa/rpi/controller/rpi/agc_channel.cpp | 49 ++++++++++++++++++++++\n src/ipa/rpi/controller/rpi/agc_channel.h | 10 +++++\n 2 files changed, 59 insertions(+)", "diff": "diff --git a/src/ipa/rpi/controller/rpi/agc_channel.cpp b/src/ipa/rpi/controller/rpi/agc_channel.cpp\nindex 84eafe7d..dfe363ff 100644\n--- a/src/ipa/rpi/controller/rpi/agc_channel.cpp\n+++ b/src/ipa/rpi/controller/rpi/agc_channel.cpp\n@@ -170,6 +170,49 @@ readConstraintModes(std::map<std::string, AgcConstraintMode> &constraintModes,\n \treturn { 0, first };\n }\n \n+int AgcChannelConstraint::read(const libcamera::YamlObject ¶ms)\n+{\n+\tauto channelValue = params[\"channel\"].get<unsigned int>();\n+\tif (!channelValue) {\n+\t\tLOG(RPiAgc, Error) << \"AGC channel constraint must have a channel\";\n+\t\treturn -EINVAL;\n+\t}\n+\tchannel = *channelValue;\n+\n+\tstd::string boundString = params[\"bound\"].get<std::string>(\"\");\n+\ttransform(boundString.begin(), boundString.end(),\n+\t\t boundString.begin(), ::toupper);\n+\tif (boundString != \"UPPER\" && boundString != \"LOWER\") {\n+\t\tLOG(RPiAgc, Error) << \"AGC channel constraint type should be UPPER or LOWER\";\n+\t\treturn -EINVAL;\n+\t}\n+\tbound = boundString == \"UPPER\" ?
