Subject: [PATCH v2 0/8] watchdog: rtc: New driver(s) for ST's LPC IP
Date: Wed, 17 Dec 2014 16:45:19 +0000 [thread overview]
Message-ID: <1418834727-1602-1-git-send-email-lee.jones@linaro.org> (raw)
ST's Low Power Controller (LPC) controls two devices; watchdog and RTC.
Only one of the devices can be used at any one time, which is enforced
by a Device Tree property.
This driver set provides everything you need to choose one (and only
one) of the LPC devices to run per I/P block, of which there are two
on the enabled STiH407 h/w.
v1 => v2:
Suggestions fixed up:
Arnd: No need for a separate MFD driver. If you return -ENODEV
really_probe() will continue looking for an suitable alternative.
David: Power Management improvements.
Guenter: Use Watchdog Framework's maximum timeout checker and only request
clock rate once during .probe(), as the clock rate will not
change.
