Subject: [PATCH 125/141] rtc: pcf2127: add pcf2129 device id
|
||
|
|
|
||
|
|
commit e8bf83a7f9454ed1026f100139ebd10eace0e280
|
||
|
|
[context adjustment]
|
||
|
|
|
||
|
|
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.
