Here is the big char/misc driver update for 4.14-rc1.
Lots of different stuff in here, it's been an active development cycle
for some reason. Highlights are:
- updated binder driver, this brings binder up to date with what
shipped in the Android O release, plus some more changes that
happened since then that are in the Android development trees.
- coresight updates and fixes
- mux driver file renames to be a bit "nicer"
- intel_th driver updates
- normal set of hyper-v updates and changes
- small fpga subsystem and driver updates
- lots of const code changes all over the driver trees
- extcon driver updates
- fmc driver subsystem upadates
- w1 subsystem minor reworks and new features and drivers added
- spmi driver updates
Plus a smattering of other minor driver updates and fixes.
All of these have been in linux-next with no reported issues for a
while.

On the CP110 unit, which can be found on various Marvell platforms such
as the 7k and 8k (currently), a comphy (common PHYs) hardware block can
be found. This block provides a number of PHYs which can be used in
various modes by other controllers (network, SATA ...). These common
PHYs must be configured for the controllers using them to work correctly
either at boot time, or when the system runs to switch the mode used.
This patch adds a driver for this comphy hardware block, providing
callbacks for the its PHYs so that consumers can configure the modes
used.
As of this commit, two modes are supported by the comphy driver: sgmii
and 10gkr.

Detailed description for this pull request:
1. Add new 'extcon-usbc-cros-ec.c' driver
- ChromeOS Embedded Controller extcon driver supports
the detection of the Display Port (EXTCON_DISP_DP)
through USB C-type and contol it.
2. Update extcon core
- Modify the description for both functions and structures
in order to improve the readability and give the more correct
guide about the role of functions because there are different
explanation even if the same arguments.
- Keep the indentation with tab instead of space
- Remove the following deprecated extcon API. The deprecated API
are exchanged on all of linux tree.
: extcon_get_cable_state_() -> extcon_get_state()
: extcon_set_cable_state_() -> extcon_set_state_sync()
3. Include the two immutable branch as following:
- ib-extcon-mfd-4.14 for the 'extcon-ubsc-cros-ec.c' driver
because the patches of 'extcon-ubsc-cros-ec.c' touch the MFD directory.
- ib-extcon-usb-phy-4.14 for removing the deprecated extcon API
because the usb/phy driver usese the deprecated extcon API.
So, this immutable branch alters the extcon API and then
remove them from extcon.
4. Fix minor issue of extcon driver
- Fix the MHL detection on extcon-max77693.c
- Convert to using %pOF instead of full_name on extcon.c
- Add 'const' kerywod for acpi_device_id on extcon-intel-int3496.c

Casting between an 'int' and a pointer causes a warning on
64-bit architectures in compile-testing this driver:
drivers/phy/ralink/phy-ralink-usb.c: In function 'ralink_usb_phy_probe':
drivers/phy/ralink/phy-ralink-usb.c:195:13: error: cast from pointer to
integer of different size [-Werror=pointer-to-int-cast]
This changes the code to cast to uintptr_t instead. This is
guaranteed to do what we want on all architectures and avoids
the warning.

On all Allwinner SoCs that share the common USB PHY design supported by
the phy-sun4i-usb driver, the first PHY is always tied to OTG, and there
is at most one HSIC PHY, typically the last.
In this patch we take advantage of these known constraints and store an
index in the compatible-string-related config structure describing which
PHY is HSIC, needing the extra hsic_12M clock.

In rockchip-inno-usb2 phy driver, we use otg_sm_work to
dynamically manage power consumption for phy otg-port.
If the otg-port works as peripheral mode and does not
communicate with usb host, we will suspend phy.
But once suspend phy, the phy no longer has any internal
clock running, include the utmi_clk which supplied for
usb controller. So if we suspend phy before usb controller
init, it will cause usb controller fail to initialize.
Specifically, without this patch, the observed order is:
1. unplug usb cable
2. start system, do dwc2 controller probe
3. dwc2_lowlevel_hw_enable()
- phy_init()
- rockchip_usb2phy_init()
- schedule otg_sm_work after 2s
put phy in suspend, and close utmi_clk
4. dwc2_hsotg_udc_start() - fail to initialize the usb core
Generally, dwc2_hsotg_udc_start() can be called within 5s
after start system on Rockchip platform, so we increase the
the first schedule delay time to 6s for otg_sm_work afer usb
controller calls phy_init(), this can make sure that the usb
controller completes initialization before phy enter suspend.

Some Motorola phones like droid 4 use a custom CPCAP PMIC that has a
multiplexing USB PHY.
This USB PHY can operate at least in four modes using pin multiplexing
and two control GPIOS:
- Pass through companion PHY for the SoC USB PHY
- ULPI PHY for the SoC
- Pass through USB for the modem
- UART debug console for the SoC
This patch adds support for droid 4 USB PHY and debug UART modes,
support for other modes can be added later on as needed.
Both peripheral and host mode are working for the USB. The
host mode depends on the cpcap-charger driver for VBUS.
VBUS and ID pin detection are done using cpcap-adc IIO ADC
driver.

The Kconfig currently controlling compilation of this code is:
drivers/phy/Kconfig:config PHY_EXYNOS_PCIE
drivers/phy/Kconfig: bool "Exynos PCIe PHY driver"
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

This reverts commit d7bc1a7d41 ("phy: Add USB3 PHY support for
Broadcom NSP SoC") as we already have driver for this PHY (shared by NS
and NSP). It was added in commit e5666281d9 ("phy: bcm-ns-usb3: new
driver for USB 3.0 PHY on Northstar").
Instead of adding separated driver & duplicating code we should work on
improving existing (old) one. Thanks to work done by Broadcom we know
there is MDIO bus we weren't aware of & we know register names which
makes initialization more clear. This is very valuable info and we
should work on using it in existing driver afterwards.

The fact that a regulator is always-on is a property of the regulator,
not a specific consumer. Implementing this in the driver leads to a
system behaviour that is dependent on if the Qualcomm UFS PHY was ever
(partially) probed.
If the specific regulator should be always on in a particular device,
mark it so by specifying "regulator-always-on" in the regulator node.

Upon failing to acquire regulator supplies the qcom-ufs driver calls
kfree() on the devm allocated memory used to store the name of the
regulator, leading to devres corruption.
Rather than switching to using the appropriate free function the patch
acknowledge the fact that "name" is always a constant string and we
don't actually need to create a local copy of it, but rather just
reference the constant string.
