Before adding the UART driver module, I did refactoring the s3fwrn5_i2c module to reuse the common blocks. 1/4 is the dt bindings for the RN82 UART interface. 2/4..3/4 are refactoring the s3fwrn5_i2c module. 4/4 is the UART driver module implementation. ChangeLog: v4: 1/4 - change 'oneOf' to 'items'. - fix the indentation. 2/4 - add the ACK tag. 4/4 - remove the of_match_ptr macro. v3: 3/4 - move the phy_common object to s3fwrn.ko to avoid duplication. - include the header files to include everything which is used inside. - wrap the lines. 4/4 - remove the kfree(phy) because of duplicated free. - use the phy_common blocks. - wrap lines properly. v2: 1/4 - change the compatible name. - change the const to enum for compatible. - change the node name to nfc. 3/4 - remove the common function's definition in common header file. - make the common phy_common.c file to define the common function. - wrap the lines. - change the Header guard. - remove the unused common function.
