[PATCH 27/31] ARM: shmobile: kzm9g dts: Configure the HOME key as wake-up source

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Note that from now on any of the pfc8575 gpio keys will wake up the
system, as the pfc8575 cannot mask individual interrupts.

Please note Brian is reconsidering this compatible value.
If the binding will be changed (which has to happen before v4.1 is released),
the above must be changed, too.

Noted. I believe we can leave this pull-request as is and
follow up with any changes as needed.

Yes we can.

Pulled into next/dt, thanks!

Please follow-up with a change for the nor-jedec property once that
discussion has concluded.

    When the USB-DMAC driver is enabled, this causes kernel oops on at least 
the R8A7791 Henninger/Porter boards (haven't checked the others yet) with 
renesas-devel-20150928-v4.3-rc3 and even earlier tag. The oops can only be 
seen with the earlyprintk=serial kernel parameter, otherwise the kernel just 
hangs with a blank console.

My current kernel on r8a7791/koelsch has CONFIG_RENESAS_USB_DMAC=y and boots
fine.

renesas-devel-20150928-v4.3-rc3 with shmobile_defconfig +
CONFIG_RENESAS_USB_DMAC=y also boots fine.

Do I need to enable/disable config options to trigger this?

I'm not sure but I am guessing this issue related runtime PM? (suspend)
I checked the usb-dmac driver roughly, and if the usb_dmac_runtime_suspend()
is called before usb_dmac_chan_probe() runs, it might happen because dmac->iomem is NULL.

What do you think?

Best regards,
Yoshihiro Shimoda

    Indeed, I was able to boot it all the way on Henninger.

    It appears so. I just don't know what -- the diff between my .config and 
shmobile_defconfig is 150+ hunks. :-(

Can you please send me your .config by private email?

   OK, my shot in the dark proved helpful: it's the kernel preemption mode -- 
shmobile_defconfig has CONFIG_PREEMPT_NONE, my .config has CONFIG_PREEMPT!

   OK.

That's exactly what's happening. Reproduced with CONFIG_PREEMPT=y (thanks
Sergei), and patch sent.
