Subject: [PATCH 702/806] overlays: Add PCF2129 RTC
|
2019-07-31 16:23:26 +00:00
|
|
|
|
|
|
|
|
Add support for the PCF2129 RTC to i2c-rtc and i2c-rtc-gpio overlays.
|
|
|
|
|
Also add rv3028 to i2c-rtc-gpio (it was missed previously), and don't
|
|
|
|
|
attempt to set an alternate address for the PCF2127.
|
|
|
|
