    5.

  9. There are only a few differences between PCF2127 and PCF2129 (PCF2127
    10. 

  10. has 512 bytes of general purpose SRAM and count-down timer).
    11. 

  11. 

  12. The rtc-pcf2127 driver currently doesn't use the PCF2127 specific
    13. 

  13. functionality and Kconfig help text already says this driver supports
    14. 

  14. PCF2127/29, so we can simply add pcf2129 to device id list.
