Pull "Second Round of Renesas ARM64 Based SoC DT Updates for v4.15" from Simon Horman:
* r8a7795 (H3) and r8a7796 (M3-W) SoCs
- Use R-Car Gen 3 fallback compat string for GPIO
Simon Horman says "Use newly added R-Car GPIO Gen 1, 2 and 3 fallback
compat strings in peace of now deprecated non-generation specific R-Car
GPIO fallback compat string in the DT of Renesas ARM and arm64 based
SoCs.
* r8a7795 (H3) and r8a7796 (M3-W) Salvator boards
- Add dr_mode property for USB2.0 channel 0
Shimoda-san says "Since Salvator-X[S] have a USB2.0 dual-role channel
(CN9), this patch
adds dr_mode property for USB2.0 channel 0 (EHCI/OHCI and HS-USB)
as "otg".
Using dual-role channel (or not) is related to the type of USB receptor
on board specification. So, I added the property into the
salvator-common.dtsi."
- Add pfc node for USB3.0 channel 0
Shimoda-san says "Since a R-Car Gen3 bootloader enables the PFC of
USB3.0 channel 0, the USB3.0 host controller works without this setting
on the kernel. But, this setting should have salvator-common.dtsi. So,
this patch adds the pfc node for USB3.0 channel 0."
* r8a7795 (H3) and r8a7796 (M3-W) Salvator and ULCB boards
- Correct audio_clkout
Morimoto-san says ""audio_clkout" is dummy clock of <&rcar_sound 0> to
avoid clock loop which invites probe conflct. Thus <&rcar_sound 0> and
"audio_clkout" should be same value."
* r8a7795 (H3) and r8a7796 (M3-W) Salvator and ULCB, and
r8a77995 (D3) Draak boards
- Drop "avb_phy_int" from avb_pins
Shimoda-san says "Since the Ethernet AVB driver doesn't support
AVB_PHY_INT handling and it will be handled by a phy driver as a gpio
pin, this patch removes the "avb_phy_int" from the avb_pins node."
* r8a77995 (D3) Draak board
- Enable PWM channels
Shimoda-san says "Each channel connects to LTC2644 for brightness
control."

The generic pte_access_permitted() implementation only checks for
pte_present() (together with the write permission where applicable).
However, for both kernel ptes and PROT_NONE mappings pte_present() also
returns true on arm64 even though such mappings are not user accessible.
Additionally, arm64 now supports execute-only user permission
(PROT_EXEC) which is implemented by clearing the PTE_USER bit.
With this patch the arm64 implementation of pte_access_permitted()
checks for the PTE_VALID and PTE_USER bits together with writable access
if applicable.

Several conflicts here.
NFP driver bug fix adding nfp_netdev_is_nfp_repr() check to
nfp_fl_output() needed some adjustments because the code block is in
an else block now.
Parallel additions to net/pkt_cls.h and net/sch_generic.h
A bug fix in __tcp_retransmit_skb() conflicted with some of
the rbtree changes in net-next.
The tc action RCU callback fixes in 'net' had some overlap with some

Pull "Second Round of Renesas ARM Based SoC DT Updates for v4.15" from Simon Horman:
* r8a77430 (RZ/G1M) SoC
- Add XHCI support to SoC DT. Boards may enable this as appropriate
* All Renesas ARM based SoCs
- Add missing clocks for ARM CPU cores
Geert Uytterhoeven says "This series improves DT hardware descriptions
for Renesas arm32 SoCs by adding missing clocks properties to the
device nodes corresponding to ARM CPU cores."
* R-Car Gen 1 and 2, and RZ/G SoCs
- Use R-Car Fallback compat strings for GPIO
Simon Horman says "Use newly added R-Car GPIO Gen 1, 2 and 3 fallback
compat strings in peace of now deprecated non-generation specific R-Car
GPIO fallback compat string in the DT of Renesas ARM and arm64 based
SoCs.
As noted in the changelogs for the r8a777[89] changes, this introduces
an incompatibility with pre-v4.14 kernels used with new DTBs. There is
no run-time effect for other SoCs updated by this changeset."
* r7s72100 (RZ/A1H) GR-Peach board
- Add pin configuration subnode for ETHER pin group.
This avoids relying on boot-loader configuration of these pins.
- Enable ostm0 and ostm1 timers
Jacopo Mondi says these are "to be used as clock source and clockevent
source. The timers provides greater accuracy than the already enabled
mtu2 one."
- Correct leds node name indent
- Enable MTU2 timer pulse unit
Jacopo Mondi says "MTU2 multi-function/multi-channel timer/counter is
not enabled for GR-Peach board. The timer is used as clock event source
to schedule wake-ups, and without this enabled all sleeps not performed
through busy waiting hang the board."
* r8a7743 (RZ/G1M) iW-RainboW-G20M-Qseven SoM
- Add USB function support
* r8a7745 (RZ/G1E) iW-RainboW-G22D development platform
- Add USB2.0 Host support
* r8a7743 (RZ/G1M) iW-RainboW-G20D-Qseven development platform
- Rework DT architecture and add DT for camera DB
Fabrizio Castro says "Some of the serial interfaces are exposed on the
camera daughter board. The camera daughter board can be connected to
the carrier board by means of expansion connectors 1, 2 and 3. The
carrier board may host an RZ/G1M or an RZ/G1N based SoM.
While adding support for the serial interfaces on the camera daughter
board we faced the dilemma of how to properly describe all of the
possible HW configurations and how to maximize code reuse.
The best option would be to use device tree overlays, however there is
still some work to be done on that front before actually using them,
therefore for the time being we decided to provide .dtsi files to
describe the carrier board and the camera daughter board, and provide
.dts files to describe the HW configurations we need to support."
* r8a779[0-4] R-Car Gen2 SoCs
- Use generic node name for VSP1 nodes
Geert Uytterhoeven says "This patch series replaces the specific node
names used for the VSP1 nodes by the preferred generic node names, cfr.
commit 0e1bfb72b076b07d ("v4l: vsp1: Use generic node name")."

'nr_pages'
register_page_bootmem_memmap()'s 3rd 'size' parameter is named
in a somewhat misleading fashion - rename it to 'nr_pages' which
makes the units of it much clearer.
Meanwhile rename the existing local variable 'nr_pages' to
'nr_pmd_pages', a more expressive name, to avoid conflict with
new function parameter 'nr_pages'.
(Also clean up the unnecessary parentheses in which get_order() is called.)

We now handle the open drain mode internally in the I2C GPIO
driver, but we will get warnings from the gpiolib that we
override the default mode of the line so it becomes open
drain.
We can fix all in-kernel users by simply passing the right
flag along in the descriptor table, and we already touched
all of these files in the series so let's just tidy it up.

This converts the GPIO-based I2C-driver to using GPIO
descriptors instead of the old global numberspace-based
GPIO interface. We:
- Convert the driver to unconditionally grab two GPIOs
from the device by index 0 (SDA) and 1 (SCL) which
will work fine with device tree and descriptor tables.
The existing device trees will continue to work just
like before, but without any roundtrip through the
global numberspace.
- Brutally convert all boardfiles still passing global
GPIOs by registering descriptor tables associated with
the devices instead so this driver does not need to keep
supporting passing any GPIO numbers as platform data.
There is no stepwise approach as elegant as this, I
strongly prefer this big hammer over any antsteps for this
conversion. This way the old GPIO numbers go away and
NEVER COME BACK.
Special conversion for the different boards utilizing
I2C-GPIO:
- EP93xx (arch/arm/mach-ep93xx): pretty straight forward as
all boards were using the same two GPIO lines, just define
these two in a lookup table for "i2c-gpio" and register
these along with the device. None of them define any
other platform data so just pass NULL as platform data.
This platform selects GPIOLIB so all should be smooth.
The pins appear on a gpiochip for bank "G" as pins 1 (SDA)
and 0 (SCL).
- IXP4 (arch/arm/mach-ixp4): descriptor tables have to
be registered for each board separately. They all use
"IXP4XX_GPIO_CHIP" so it is pretty straight forward.
Most board define no other platform data than SCL/SDA
so they can drop the #include of <linux/i2c-gpio.h> and
assign NULL to platform data.
The "goramo_mlr" (Goramo Multilink Router) board is a bit
worrisome: it implements its own I2C bit-banging in the
board file, and optionally registers an I2C serial port,
but claims the same GPIO lines for itself in the board file.
This is not going to work: there will be competition for the
GPIO lines, so delete the optional extra I2C bus instead, no
I2C devices are registered on it anyway, there are just hints
that it may contain an EEPROM that may be accessed from
userspace. This needs to be fixed up properly by the serial
clock using I2C emulation so drop a note in the code.
- KS8695 board acs5k (arch/arm/mach-ks8695/board-acs5.c)
has some platform data in addition to the pins so it needs to
be kept around sans GPIO lines. Its GPIO chip is named
"KS8695" and the arch selects GPIOLIB.
- PXA boards (arch/arm/mach-pxa/*) use some of the platform
data so it needs to be preserved here. The viper board even
registers two GPIO I2Cs. The gpiochip is named "gpio-pxa" and
the arch selects GPIOLIB.
- SA1100 Simpad (arch/arm/mach-sa1100/simpad.c) defines a GPIO
I2C bus, and the arch selects GPIOLIB.
- Blackfin boards (arch/blackfin/bf533 etc) for these I assume
their I2C GPIOs refer to the local gpiochip defined in
arch/blackfin/kernel/bfin_gpio.c names "BFIN-GPIO".
The arch selects GPIOLIB. The boards get spiked with
IF_ENABLED(I2C_GPIO) but that is a side effect of it
being like that already (I would just have Kconfig select
I2C_GPIO and get rid of them all.) I also delete any
platform data set to 0 as it will get that value anyway
from static declartions of platform data.
- The MIPS selects GPIOLIB and the Alchemy machine is using
two local GPIO chips, one of them has a GPIO I2C. We need
to adjust the local offset from the global number space here.
The ATH79 has a proper GPIO driver in drivers/gpio/gpio-ath79.c
and AFAICT the chip is named "ath79-gpio" and the PB44
PCF857x expander spawns from this on GPIO 1 and 0. The latter
board only use the platform data to specify pins so it can be
cut altogether after this.
- The MFD Silicon Motion SM501 is a special case. It dynamically
spawns an I2C bus off the MFD using sm501_create_subdev().
We use an approach to dynamically create a machine descriptor
table and attach this to the "SM501-LOW" or "SM501-HIGH"
gpiochip. We use chip-local offsets to grab the right lines.
We can get rid of two local static inline helpers as part
of this refactoring.

After finding out there are active users of this sensor I noticed:
- It has a single PXA27x board file using the platform data
- The platform data is only used to carry two GPIO pins, all other
fields are unused
- The driver does not use GPIO descriptors but the legacy GPIO
API
I saw we can swiftly fix this by:
- Killing off the platform data entirely
- Define a GPIO descriptor lookup table in the board file
- Use the standard devm_gpiod_get() to grab the GPIO descriptors
from either the device tree or the board file table.
This compiles, but needs testing.

Meson6, Meson8 and Meson8b use a similar IP block which has access to
512 bytes of efuse data.
During SoC manufacturing some calibration settings for the CVBS
connector and the internal temperature sensor are written to this efuse.
On some boards it additionally stores for example the MAC addresses.
The efuse is enabled on Meson8 and Meson8b but kept disabled on Meson6
since we do not have a clock driver there (which is required to read
data from the efuse).

On Amlogic Meson8 / Meson8m2 (both Cortex-A9) and Meson8b (Cortex-A5)
the CPU hotplug code needs to wait until the SCU status of the CPU that
is being taken offline is SCU_PM_POWEROFF.
Provide a utility function (which can be invoked for example from
.cpu_kill()) which allows reading the SCU status of a CPU.
While here, replace the magic number 0x3 with a preprocessor macro
(SCU_CPU_STATUS_MASK) so we don't have to duplicate this magic number in
the new function.
