Marvell keeps their MMP2 datasheet secret, but there are good clues
that TWSI2 is not on 0xd4025000 on that platform, not does it use
IRQ 58. In fact, the IRQ 58 on MMP2 seems to be a signal processor:

   arch/arm/mach-mmp/irqs.h:#define IRQ_MMP2_MSP  58

I'm taking a somewhat educated guess that is probably a copy & paste
error from PXA168 or PXA910 and that the real controller in fact hides
at address 0xd4031000 and uses an interrupt line multiplexed via IRQ 17.

I'm also copying some properties from TWSI1 that were missing or
incorrect.

Tested on a OLPC XO 1.75 machine, where the RTC is on TWSI2.

The standard reset-simple driver the uses the "altr,rst-mgr" binding is
not getting initialized early enough in the boot process, so timers
that the kernel needs are still left in reset. Thus an early
reset driver was created. This early reset driver is only for the
SoCFPGA 32-bit platform.

The Stratix10 platform does not need any of the timers that in reset to
boot, thus we don't need to early reset driver. Therefore, use the
"altr,stratix10-rst-mgr" binding for the reset-simple platform driver on
the Stratix10 platform.

Also remove the "altr,modrst-offset" property because the driver no
longer needs it.

Althought interface SDHI1 found on the RZ/G1C SoC (a.k.a.
r8a77470) is compatible with the R-Car Gen3 ones, its OF
compatibility is restricted to the SoC specific compatible
string to avoid confusion, as from a more generic perspective
the RZ/G1C is sharing the most similarities with the R-Car
Gen2 family of SoCs, and there is a combination of R-Car
Gen2 compatible SDHI IPs and R-Car Gen3 compatible SDHI IP
on this specific chip.
This patch adds the SoC specific part of SDHI1 support, and
since SDHI1 comes with internal DMA, its DT node looks fairly

Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.

Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.

Update cooling maps to include all devices affected by individual trip
points.
