Pull "Rockchip dts32 changes for 4.14" from Heiko Stübner:
Removal of the deprectated num-slots property from all Rockchip dw-mmc
nodes. The rv1108 gains support for sd-cards on the evaluation board and
the general nodes get a bit of cosmetic. On rk3288 the evb gains support
saradc and the adc-key connected to it while some more boards also get
their mali gpu enabled (fennec, evb, tinker).
The biggest set of changes can be found on the rk3228/rk3229 combo this
time. It gets core support for efuse, sdmmc, sdio, io-domans and spdif
as well as a separate rk3229.dtsi that will keep the slight differences
between the two brothers rk3228/rk3229. The evaluation board also gets
some attention and abled nodes (regulators, io-domains, emmc, tsadc keys)
But I think the most interesting change is the cpu enable-method for it.
Instead of using the older in-kernel method, we're now also moving to
handling this in firmware via the psci interface on 32bit Rockchip socs.
In a recently merged pull request [0] support for the rk3228/rk3229 was
added to OP-TEE including the psci support and it seems supporting other
32bit Rockchip socs that way is also planned for the future.

Changes of note:
* Add pin controller support to the RZ/G1M (r8a7743) SoC and
RZ/A1 (r7s72100) SoCs now that the driver is available in v4.13-rc1.
* Add GPIO support to the RZ/G1M (r8a7743) SoC now that the driver
is availabe in v4.13-rc1.
* Enable MMCIF0 and Ethernet AVB support on the RZ/G1M (r8a7743) SoC and
the iWave-RZG1M-20M Qseven SOM. This depends on newly added pin
controller support noted above.
* Use R-Car Gen 2 fallback binding for vin nodes
This makes binding use consistent across R-Car Gen 2 SoCs.
It does not have any run-time effect
* Use SMP jump stub SRAM region from DT on R-Car Gen 2 SoCs
Geert Uytterhoeven says, "The R-Car Gen2 platform code for CPU core
bringup needs to copy a jump stub to on-SoC SRAM. Currently it uses a
hardcoded address pointing to ICRAM1."
* Add Inter Connect RAM to R-Car Gen 2 and RZ/G1 SoCs
Geert Uytterhoeven says, "R-Car Gen2 and RZ/G1 SoCs contain two or three
blocks of SRAM, which can be used for several purposes. One such purpose
is holding a jump stub for CPU core bringup."
* Use generic compatible string for I2C EEPROM for RZ/A1 (r7s72100) SoC
and koelsch board.

Currently the default method of prefetch polled shows the highest
possible read and write speed when minimal non NAND background
activity is being done. But it is also very CPU intensive to reach
these high speeds (CPU load of 99% via mtd performance tests). While
DMA prefetch only uses 50% of the CPU to achieve around 23% less in
top read and write performance.
However, as the non NAND CPU load increases the read and write
performance takes a large hit when using polled prefetch. Therefore,
prefetch dma mode ends up outperforming prefetch polled in general
"system level" test. So switch to using dma prefetch by default since
it is likely what most users would prefer.

such as tpd12s015 or ip4791cz12 have the CEC pull in the encoder
chip. And on var-som-om44, there is external pull up resistor R30.
So the internal CEC pull-up resistor needs to be disabled as otherwise
the external and internal pull are parallel making the pull value
much smaller than intended. This leads into the CEC not working as
reported by Hans Verkuil <hverkuil@xs4all.nl>.

This patch adds the missing 32-bit enable method for SMP on BCM2836 and
BCM2837. The BCM2837 already has an enabled method, but this one only
works for 64-bit.
