Set the capacity-dmips-mhz for R-Car Gen3 SoCs, that is based on
dhrystone. The average in 10 times of dhrystone result as follows:
r8a7795 SoC (A57x4 + A53x4)
CPU max-freq dhrystone
---------------------------------
A57 1500 MHz 11470943 lps/s
A53 1200 MHz 4798583 lps/s
r8a7796 SoC (A57x2 + A53x4)
CPU max-freq dhrystone
---------------------------------
A57 1500 MHz 11463526 lps/s
A53 1200 MHz 4793276 lps/s
Based on above, capacity-dmips-mhz values are calculated as follows:
r8a7795 SoC
A57 : 1024 / (11470943 / 1500) * (11470943 / 1500) = 1024
A53 : 1024 / (11470943 / 1500) * ( 4798583 / 1200) = 535
r8a7796 SoC
A57 : 1024 / (11463526 / 1500) * (11463526 / 1500) = 1024
A53 : 1024 / (11463526 / 1500) * ( 4793276 / 1200) = 535
However, since each CPUs have different max frequencies, the final
CPU capacities of A53 are scaled by this difference, the values are
as follows.
[r8a7795 SoC]
$ cat /sys/devices/system/cpu/cpu*/cpu_capacity
1024 <---- CPU capacity of A57
1024
1024
1024
428 <---- CPU capacity of A53
428
428
428
[r8a7796 SoC]
$ cat /sys/devices/system/cpu/cpu*/cpu_capacity
1024 <---- CPU capacity of A57
1024
428 <---- CPU capacity of A53

Then, BUSIF DMA settings on rcar_sound,ssi (= rxu, txu) are

this patch doesn't remove it so far, but will be removed in

The eMMC card has two supplies, VCC and VCCQ. The VCC supplies the NAND
array and the VCCQ supplies the bus. On Salvator-X and ULCB, the VCC is
connected to 3.3V rail, while the VCCQ is connected to 1.8V rail. Adjust
the pinmux to match the bus, which is always operating in 1.8V mode.
While at it, deduplicate the pinmux entries, which are now the same for
both default and UHS modes. We still need the two pinctrl entries to
match the bindings though.

This patch adds/enables USB2.0 peripheral for R-Car [DE]3 boards.
R-Car E3 Ebisu board connects the ID pin to the SoC, so this adds
a group "usb0_id" into usb0_pins node. Also, to use SW15 pin 3 side,
this patch adds vbus0_usb2 node on r8a77990-ebisu.dts.
R-Car D3 Draak board doesn't connect the ID pin, so this adds
"renesas,no-otg-pins" property into usb2_phy0 node.
