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 :) Signed-off-by: Alexander Clouter Alexander Clouter (3): rtc: rtc-m48t86: add devicetree bindings arm: orion5x: fixup ts78xx to be able to use the rtc-m48t86 again. arm: ep93xx: fixup ts72xx to be able to use the rtc-m48t86 again. .../devicetree/bindings/rtc/rtc-m48t86.txt | 17 ++ arch/arm/mach-ep93xx/ts72xx.c | 29 +-- arch/arm/mach-orion5x/ts78xx-setup.c | 79 ++---- drivers/rtc/rtc-m48t86.c | 254 +++++++++++++++----- include/linux/m48t86.h | 16 -- 5 files changed, 239 insertions(+), 156 deletions(-) create mode 100644 Documentation/devicetree/bindings/rtc/rtc-m48t86.txt delete mode 100644 include/linux/m48t86.h -- 1.7.10.4
