Clocks related to DISP1 block require special handling for power domain
turn on/off sequences. Till now this was handled by Exynos power domain
driver, but that approach was limited only to some special cases. This
patch moves handling of those operations to clock controller driver.
This gives more flexibility and allows fine tune values of some
clock-specific registers. This patch moves handling of those mentioned
clocks to Exynos5 sub-CMU driver instantiated from Exynos5250 driver.

Handling of clock reparenting will be move to clock controller driver,
so add possibility to blacklist clock handling on systems, where the
clock controller already does all needed operations. This is needed
to avoid potential deadlock on clock reparenting during power domain

Pull ARM SoC fixes from Arnd Bergmann:
"This is the first set of bugfixes for ARM SoCs, fixing a couple of
stability problems, mostly on TI OMAP and Rockchips platforms:
- OMAP2 hwmod clocks must be enabled in the correct order
- OMAP3 Wakeup from resume through PRM IRQ was unreliable
- one regression on OMAP5 caused by a kexec fix
- Rockchip ethernet needs some settings for stable operation on
Rock64
- Rockchip based Chrombook Plus needs another clock setting for
stable display suspend/resume
- Rockchip based phyCORE-RK3288 was able to run at an invalid CPU
clock frequency
- Rockchip MMC link was sometimes unreliable
- multiple fixes to avoid crashes in the Broadcom STB DPFE driver
Other minor changes include:
- Devicetree fixes for incorrect hardware description (rockchip,
omap, Gemini, amlogic)
- some MAINTAINER file updates to correct email and git addresses
- some fixes addressing 'make W=1' dtc warnings (broadcom, amlogic,

AM335x and AM437x support various low power modes as documented
in section 8.1.4.3 of the AM335x Technical Reference Manual and
section 6.4.3 of the AM437x Technical Reference Manual.
DeepSleep0 mode offers the lowest power mode with limited
wakeup sources without a system reboot and is mapped as
the suspend state in the kernel. In this state, MPU and
PER domains are turned off with the internal RAM held in
retention to facilitate the resume process. As part of
the boot process, the assembly code is copied over to OCMCRAM
so it can be executed to turn of the EMIF and put DDR into self
refresh.
Both platforms have a Cortex-M3 (WKUP_M3) which assists the MPU
in DeepSleep0 entry and exit. WKUP_M3 takes care
of the clockdomain and powerdomain transitions based on the
intended low power state. MPU needs to load the appropriate
WKUP_M3 binary onto the WKUP_M3 memory space before it can
leverage any of the PM features like DeepSleep. This loading
is handled by the remoteproc driver wkup_m3_rproc.
Communication with the WKUP_M3 is handled by a wkup_m3_ipc
driver that exposes the specific PM functionality to be used
the PM code.
In the current implementation when the suspend process
is initiated, MPU interrupts the WKUP_M3 to let it know about
the intent of entering DeepSleep0 and waits for an ACK. When
the ACK is received MPU continues with its suspend process
to suspend all the drivers and then jumps to assembly in
OCMC RAM. The assembly code puts the external RAM in self-refresh
mode, gates the MPU clock, and then finally executes the WFI
instruction. Execution of the WFI instruction with MPU clock gated
triggers another interrupt to the WKUP_M3 which then continues
with the power down sequence wherein the clockdomain and
powerdomain transition takes place. As part of the sleep sequence,
WKUP_M3 unmasks the interrupt lines for the wakeup sources. WFI
execution on WKUP_M3 causes the hardware to disable the main
oscillator of the SoC and from here system remains in sleep state
until a wake source brings the system into resume path.
When a wakeup event occurs, WKUP_M3 starts the power-up
sequence by switching on the power domains and finally
enabling the clock to MPU. Since the MPU gets powered down
as part of the sleep sequence in the resume path ROM code
starts executing. The ROM code detects a wakeup from sleep
and then jumps to the resume location in OCMC which was
populated in one of the IPC registers as part of the suspend
sequence.
Code is based on work by Vaibhav Bedia.

Changes since v1:
Added changes in these files:
drivers/infiniband/hw/usnic/usnic_transport.c
drivers/staging/lustre/lnet/lnet/lib-socket.c
drivers/target/iscsi/iscsi_target_login.c
drivers/vhost/net.c
fs/dlm/lowcomms.c
fs/ocfs2/cluster/tcp.c
security/tomoyo/network.c
Before:
All these functions either return a negative error indicator,
or store length of sockaddr into "int *socklen" parameter
and return zero on success.
"int *socklen" parameter is awkward. For example, if caller does not
care, it still needs to provide on-stack storage for the value
it does not need.
None of the many FOO_getname() functions of various protocols
ever used old value of *socklen. They always just overwrite it.
This change drops this parameter, and makes all these functions, on success,
return length of sockaddr. It's always >= 0 and can be differentiated
from an error.
Tests in callers are changed from "if (err)" to "if (err < 0)", where needed.
rpc_sockname() lost "int buflen" parameter, since its only use was
to be passed to kernel_getsockname() as &buflen and subsequently
not used in any way.
Userspace API is not changed.

We were making a bunch of wrong assumptions that turned out to blow out
on non-Broadcom STB platforms:
- we would return -ENODEV from brcmstb_soc_device_early_init() if we
could not find the sun_top_ctrl device node, this is not an error
in the context of a multi-platform kernel
- we would still try to register the Broadcom STB SoC device, even if we
are not running on such a platform
While at it, also fix the sun_top_ctrl device_node leaks while we change
the flow of brcmstb_soc_device_init() and
brcmstb_soc_device_early_init().

Currently if this driver is included, we get the following warning
on any platforms irrespective of whether it's brcmstb platform or not.
"
brcmstb: biuctrl: missing BIU control node
brcmstb: biuctrl: MCP: Unable to disable write pairing!
"
This patch allows to exit early without any warning messages on non
brcmstb platforms as it's meaningless for them.

After moving the SoC device initialization to an early initcall in
commit f780429adfbc ("soc: brcmstb: biuctrl: Move to early_initcall"),
the Broadcom STB SoC device is registered on all platforms if support
for the device is enabled in the kernel configuration.
This causes an additional SoC device to appear on platforms that already
register a native one. In case of Tegra the STB SoC device is registered
as soc0 (with totally meaningless content in the sysfs attributes) and
causes various scripts and programs to fail because they don't know how
to parse that data.
To fix this, duplicate the check from brcmstb_soc_device_early_init()
that already prevents the code from doing anything nonsensical on non-
STB platforms.

Xilinx ZYNQMP logicoreIP Init driver is based on the new
LogiCoreIP design created. This driver provides the processing system
and programmable logic isolation. Set the frequency based on the clock
information get from the logicoreIP register set.

Second Round of Renesas ARM Based SoC Updates for v4.16
* rcar-sysc: Keep wakeup sources active during system suspend
Geert Uytterhoeven says "If an R-Car SYSC slave device is part of the
CPG/MSTP or CPG/MSSR Clock Domain and to be used as a wakeup source, it
must be kept active during system suspend.
Currently this is handled in device-specific drivers by explicitly
increasing the use count of the module clock when the device is
configured as a wakeup source. However, the proper way to prevent the
device from being stopped is to inform this requirement to the genpd
core, by setting the GENPD_FLAG_ACTIVE_WAKEUP flag.
Note that this will only affect devices configured as wakeup sources."
