 This is wrong bindings. Yes I know that it's working with our driver
for ths but this is wrong.
 1) ths module isn't in ahb but apb.
 2) We need nvmem framework to get the sensor calibration data, please

 What is the point of the spigen interface ?
 If aw_spi is working on H3 (I haven't check but it should), if you
have a good dtb with the spi flash described you can use it directly.
