hi, Heiko Schocher Some soc related files use i2c_read, i2c_write similar function interface, if you do not use the CONFIG_DM_I2C_COMPAT option to compile, there will be a function undefined compilation error, but if you do CONFIG_DM_I2C_COMPAT=y When compiling, there will be the following warnings:
===================== WARNING ====================== This board uses CONFIG_DM_I2C_COMPAT. Please remove (possibly in a subsequent patch in your series) before sending patches to the mailing list. ==================================================== If I do ONFIG_DM_I2C_COMPAT=y, do I need to implement i2c_read, i2c_write such as the function interface definition in the i2c controller driver? But these function declarations are all from include/i2c.h, if CONFIG_DM_I2C=y, these functions are not declared. How should I be compatible with these old-style interfaces? look forward to your reply!
