2021-06-30ipa: raspberrypi: Generalise the SMIA metadata parserNaushir Patuck
Instead of having each CamHelper subclass the MdParserSmia, change the implementation of MdParserSmia to be more generic. The MdParserSmia now gets given a list of registers to search for and helper functions are used to compute exposure lines and gain codes from these registers. Update the imx219 and imx477 CamHelpers by using this new mechanism.
