From cee2cc21550648679d222cbe2637fcc6d0f730ef Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Mon, 14 Mar 2016 23:45:01 +0900 Subject: [PATCH] rtc: pcf2127: add pcf2129 device id There are only a few differences between PCF2127 and PCF2129 (PCF2127 has 512 bytes of general purpose SRAM and count-down timer). The rtc-pcf2127 driver currently doesn't use the PCF2127 specific functionality and Kconfig help text already says this driver supports PCF2127/29, so we can simply add pcf2129 to device id list.
