Subject: [PATCH 0/4] rtc: pcf2127: tamper timestamp and watchdog feature support
Date: Mon, 22 Jul 2019 17:58:07 +0200 [thread overview]
Message-ID: <20190722155811.11980-1-bruno.thomsen@gmail.com> (raw)
Hi Alexandre
This patch series adds support for 2 chip features; tamper
timestamp and watchdog. Including improvements and cleanup
of existing code.
Tamper timestamp sysfs interface should match ISL1208 and
RV3028 RTC drivers; /sys/class/rtc/rtcX/timestamp0.
Watchdog functionality can be enabled with a Kconfig option,
just like in DS1374 and M41T80 RTC drivers.
In the future we could consider making a generic optional
RTC device tree binding property to enable the watchdog
feature, ex. enable-watchdog.
Patches has been tested on a pcf2127 chip using 2MHz SPI
interface both as built-in and module including with and
without watchdog feature.
