Subject: [PATCH 0/3] add devicetree bindings for rtc-m48t86
Date: Sun, 31 Mar 2013 22:56:08 +0100 [thread overview]
Message-ID: <1364766971-5914-1-git-send-email-alex@digriz.org.uk> (raw)
Currently there are two users of rtc-m48t86 (mach-ep93xx/ts72xx.c and
mach-orion5x/ts78xx-setup.c) and both just use {read,write}b against
a memory mapped region. As I am devicetree'ing the TS-7800, this
driver needs converting and thats what this patchset does.
The patch does the following:
* remove platform specific ops hooks, moving ioremap'ing and
everything into the driver
* utilises named resources to indicate index/data ranges
* moves the RTC detection routine from ts78xx-setup.c into rtc-m48t86.c
* and, of course, enable devicetree hooks and include documentation
Awkward step, the first patch breaks both boards, the two following
patches fix them. Happy to re-work this if folks give me a pointer
on how to do this in an acceptable way.
My vote is to break fast, fix fast, spend the time writing other code :)
