   4 Subject: [PATCH 125/141] rtc: pcf2127: add pcf2129 device id
   5
   6 commit e8bf83a7f9454ed1026f100139ebd10eace0e280
   7 [context adjustment]
   8
   9 There are only a few differences between PCF2127 and PCF2129 (PCF2127
  10 has 512 bytes of general purpose SRAM and count-down timer).
  11
  12 The rtc-pcf2127 driver currently doesn't use the PCF2127 specific
  13 functionality and Kconfig help text already says this driver supports
  14 PCF2127/29, so we can simply add pcf2129 to device id list.
