of usb on the evaluation board), while rk3368 gains support for spdif.
The biggest chunk of course aims for the rk3399 with a number of pcie

on the firefly board and dynamic-power-coefficients.
The gru family also gets support for their quite central pwm regulators

* Add usb2.0 for R-Car H3 (r8a7795) ES2.0 SoC
* Add R-Car D3 (r8a77995) SoC and Draak board support
Adds minimal support for the R-Car D3 SoC and the Draak development
board, allowing to boot from a ramdisk using a serial console.
* Add Add VC6 clock generator to R-Car H3 (r8a7795)/Salvator-XS board
The VC6 is an I2C-controlled programmable clock generator, used on the
board to provide a display dot clock. Add it to DT.
* Add missing second pair of DMA names to MSIOF nodes to
R-Car M3-W (r8a7796) SoC
MSIOF0 and MSIOF1 are tied to two DMA controllers through two pairs of
DMA specifiers. However, the second pair of corresponding DMA names was
missing.
* Add support for the DU to R-Car H3 (r8a7795) SoC
Add a compatible string and VSP links to the DU node. The H3 ES1.x and H3
ES2.0 are compatible save for the links to the VSPs that are described
explicitly in DT, so there's no need for a new ES2-specific compatible
string.
* Enable HDMI on R-Car H3 (r8a7795) and M3-W (r8a7796) ULCB boards
* Enable DU on R-Car M3-W (r8a7796) Salvator-X board
* Enable I2C for DVFS on R-Car H3 (r8a7795) and M3-W (r8a7796) ULCB boards
* Add Add DRIF support to R-Car H3 (r8a7795) and M3-W (r8a7796) SoCs
Ramesh Shanmugasundaram says, "R-Car Gen3 DRIF is a SPI like receive only
slave device."
* Move CPG_AUDIO_CLK_I from board to soc files
Geert Uytterhoeven says, "The definition of CPG_AUDIO_CLK_I is
SoC-specific, not board-specific."
* Add IMR-LX4 support to R-Car H3 (r8a7795) and M3-W (r8a7796) SoCs
Sergei Shtylyov says, "The image renderer light extended 4 (IMR-LX4) or
the distortion correction engine is a drawing processor with a simple
instruction system capable of referencing data on an external memory as
2D texture data and performing texture mapping and drawing with respect
to any shape that is split into triangular objects."

This comes a bit later than I planned, and as a consequence is a larger
than it should be.
Most of the changes are devicetree fixes, across lots of platforms:
Renesas, Samsung Exynos, Marvell EBU, TI OMAP, Rockchips, Amlogic Meson,
Sigma Desings Tango, Allwinner SUNxi and TI Davinci.
Also across many platforms, I applied an older series of simple randconfig
build fixes. This includes making the CONFIG_MTD_XIP option compile again,
which had been broken for many years and probably has not been missed, but
it felt wrong to just remove it completely.
The only other changes are:
- We enable HWSPINLOCK in defconfig to get some Qualcomm boards
to work out of the box.
- A few regression fixes for Texas Instruments OMAP2+.
- A boot regression fix for the Renesas regulator quirk.
- A suspend/resume fix for Uniphier SoCs, fixing the resume of the
system bus.

this compiler warning:

It would be preferrable to use GENMASK_ULL() instead, but it's not set
up to be used from assembly (the UL() macro token pastes UL suffixes
when not included in assembly sources).

In a system with DBM (dirty bit management) capable agents there is a
possible race between a CPU executing ptep_set_access_flags() (maybe
non-DBM capable) and a hardware update of the dirty state (clearing of
PTE_RDONLY). The scenario:
a) the pte is writable (PTE_WRITE set), clean (PTE_RDONLY set) and old
(PTE_AF clear)
b) ptep_set_access_flags() is called as a result of a read access and it
needs to set the pte to writable, clean and young (PTE_AF set)
c) a DBM-capable agent, as a result of a different write access, is
marking the entry as young (setting PTE_AF) and dirty (clearing
PTE_RDONLY)
The current ptep_set_access_flags() implementation would set the
PTE_RDONLY bit in the resulting value overriding the DBM update and
losing the dirty state.
This patch fixes such race by setting PTE_RDONLY to the most permissive
(lowest value) of the current entry and the new one.

In an ideal world, CNTFRQ_EL0 always contains the timer frequency
for the kernel to use. Sadly, we get quite a few broken systems
where the firmware authors cannot be bothered to program that
register on all CPUs, and rely on DT to provide that frequency.
So when trapping CNTFRQ_EL0, make sure to return the actual rate
(as known by the kernel), and not CNTFRQ_EL0.

This patch updates the dynamic-power-coefficient for big cluster on
rk3399 SoCs.
The dynamic power consumption of the CPU is proportional to the square of
the Voltage (V) and the clock frequency (f). The coefficient is used to
calculate the dynamic power as below -
Pdyn = dynamic-power-coefficient * V^2 * f
Where Voltage is in uV, frequency is in MHz.
As the following is the tested data on rk3399's big cluster.
frequency(MHz) Voltage(V) Current(mA) Dynamic-power-coefficient
24 0.8 15
48 0.8 23 ~417
96 0.8 40 ~443
216 0.8 82 ~438
312 0.8 115 ~430
408 0.8 150 ~455
So the dynamic-power-coefficient average value is about 436.
