This must have been a merge error. There was a patch which renamed the u9540.dts to ccu9540.dts, however the u9540.dts was reincarnate with the same patches which created it in the first place.

The watchdog infrastructure in Dove is no different from that in Orion5x or Kirkwood, so let's enable it for Dove. The only things missing are a few register settings in Dove's bridge-regs.h. Rather than duplicating the same register bit masks for the RSTOUTn_MASK and BRIDGE_CAUSE registers, move the definitions into the watchdog driver itself.

Interrupt request doesn't use the right API: The TWD watchdog uses a per-cpu interrupt (usually interrupt #30), and the GIC configuration should flag it as such. With this setup, request_irq() should fail, and the right API is request_percpu_irq(), together with enable_percpu_irq()/disable_percpu_irq(). Nothing ensures the userspace ioctl() will end-up kicking the watchdog on the right CPU. There are no users of this driver since a long time and it makes more sense to get rid of it as nobody is looking to fix it. In case somebody wakes up after this has been removed and needs it, please revert this driver and pick these updates (These were never pushed to mainline): http://comments.gmane.org/gmane.linux.ports.arm.kernel/245998 Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

Failure to add the mapping created in debug_ll_io_init() can lead to the BUG_ON() triggering in lib/ioremap.c:27 if the static virtual address decided for the debug_ll mapping overlaps with another mapping that is created later. This happens because the generic ioremap code has no idea there is a mapping there and it tries to place a mapping in the same location and blows up when it sees that there is a pte already present. kernel BUG at lib/ioremap.c:27!

Macro __INIT is used to place various code in head-common.S into the init section. This should be matched by a closing __FINIT. Also, add an explicit ".text" to ensure subsequent code is placed into the correct section; __FINIT is simply a closing marker to match __INIT and doesn't guarantee to revert to .text. This historically caused no problem, because macro __CPUINIT was used at the exact location where __FINIT was missing, which then placed following code into the cpuinit section. However, with commit 22f0a273 "init.h: remove __cpuinit sections from the kernel" applied, __CPUINIT becomes a no-op, thus leaving all this code in the init section, rather than the regular text section. This caused issues such as secondary CPU boot failures or crashes.
