Where do you set the I2C_CLIENT_PEC flag for the slave? Is your backend
code publicly available?
I may need a second thought here, but I am not sure I2C_CLIENT_PEC is
the right way to enable PEC. Isn't it actually depending on the backend
if PEC is needed? I.e. is the backend an I2C device or an SMBus device?
