Subject: [PATCH v5 net-next 0/4] nfc: s3fwrn5: Support a UART interface

From: Bongsu Jeon <bongsu.jeon@...sung.com>

S3FWRN82 is the Samsung's NFC chip that supports the UART communication.
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:
 v5:
   1/4
    - remove the 'items' of the compatible property.
    - change the GPIO flags.
 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.

  nfc: s3fwrn5: reduce the EN_WAIT_TIME
  nfc: s3fwrn5: extract the common phy blocks
