Re: [PATCH] rtc/tpo: Driver to support rtc and wakeup on PowerNV platform

On Wed, 2014-09-10 at 11:08 +0530, Neelesh Gupta wrote:

The patch implements the OPAL rtc driver that binds with the rtc
driver subsystem. The driver uses the platform device infrastructure
to probe the rtc device and register it to rtc class framework. The
'wakeup' is supported depending upon the property 'has-tpo' present
in the OF node. It provides a way to load the generic rtc driver in
in the absence of an OPAL driver.

The patch also moves the existing OPAL rtc get/set time interfaces to the
new driver and exposes the necessary OPAL calls using EXPORT_SYMBOL_GPL.

Alessandro, given this depends on other things in the powerpc tree do you mind
if we take this through the powerpc tree with your Ack?

Or I can create a topic branch with the required powerpc changes.

cheers
