de901cc31d Input: mpr121 - switch to device tree probe
This driver currently only supports legacy platform data probe.  This
change adds device tree support and gets rid of platform data probe code
since no one is actually using mpr121 platform data in the mainline.

The device tree property parsing code is based on the work of
atmel_captouch driver.

bb60b8b35a Merge tag 'mac80211-next-for-davem-2017-01-13' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg says:

====================
For 4.11, we seem to have more than in the past few releases:
 * socket owner support for connections, so when the wifi
   manager (e.g. wpa_supplicant) is killed, connections are
   torn down - wpa_supplicant is critical to managing certain
   operations, and can opt in to this where applicable
 * minstrel & minstrel_ht updates to be more efficient (time and space)
 * set wifi_acked/wifi_acked_valid for skb->destructor use in the
   kernel, which was already available to userspace
 * don't indicate new mesh peers that might be used if there's no
   room to add them
 * multicast-to-unicast support in mac80211, for better medium usage
   (since unicast frames can use *much* higher rates, by ~3 orders of
   magnitude)
 * add API to read channel (frequency) limitations from DT
 * add infrastructure to allow randomizing public action frames for
   MAC address privacy (still requires driver support)
 * many cleanups and small improvements/fixes across the board

afc9595ea4 PCI: rockchip: Disable RC's ASPM L0s based on DT "aspm-no-l0s"
Rockchip's RC produces a 100MHz reference clock but there are two methods
for the PHY to generate it:

  (1) Use the system PLL to generate a 100MHz clock.  The PHY will relock
      it, filter signal noise, and output the reference clock.  ASPM L0s
      works correctly, but circuit noise issues make it difficult to pass
      the TX compatibility test.

  (2) Share the SoC's 24MHZ crystal oscillator with the PHY and force the
      PHY's PLL to generate 100MHz internally.  In this case, exit from
      ASPM L0s sometimes fails due to a design error in the RC receiver
      circuit.  Even if we use extended-synch, the PHY sometimes fails to
      relock the bits from FTS, which will hang the system.

We want the flexibility to use both clocking methods, so add a DT property,
"aspm-no-l0s".  If that's present, disable L0s to avoid the issues with
case (2).

331c342552 i2c: do not enable fall back to Host Notify by default
Falling back unconditionally to HostNotify as primary client's interrupt
breaks some drivers which alter their functionality depending on whether
interrupt is present or not, so let's introduce a board flag telling I2C
core explicitly if we want wired interrupt or HostNotify-based one:
I2C_CLIENT_HOST_NOTIFY.

For DT-based systems we introduce "host-notify" property that we convert
to I2C_CLIENT_HOST_NOTIFY board flag.

9f91484f6f net: dsa: make "label" property optional for dsa2
In the new DTS bindings for DSA (dsa2), the "ethernet" and "link"
phandles are respectively mandatory and exclusive to CPU port and DSA
link device tree nodes.

Simplify dsa2.c a bit by checking the presence of such phandle instead
of checking the redundant "label" property.

Then the Linux philosophy for Ethernet switch ports is to expose them to
userspace as standard NICs by default. Thus use the standard enumerated
"eth%d" device name if no "label" property is provided for a user port.
This allows to save DTS files from subjective net device names.

If one wants to rename an interface, udev rules can be used as usual.

Of course the current behavior is unchanged, and the optional "label"
property for user ports has precedence over the enumerated name.

After this we can start to activate the new driver with the old

As part of this enablement: make us depend on the old drivers
not being in use so we don't get a kernel with two competing

This patch adds a new glue driver called dwmac-dwc-qos-eth which
was based in the dwc_eth_qos as is. To assure retro-compatibility a slight
tweak was also added to stmmac_platform.

b4b7b772e8 stmmac: adding DT parameter for LPI tx clock gating
This patch adds a new parameter to the stmmac DT: snps,en-tx-lpi-clockgating.
It was ported from synopsys/dwc_eth_qos.c and it is useful if lpi tx clock
gating is needed by stmmac users also.

003910ebc8 pinctrl: Introduce TI IOdelay configuration driver
SoC family such as DRA7 family of processors have, in addition
to the regular muxing of pins (as done by pinctrl-single), a separate
hardware module called IODelay which is also expected to be configured.
The "IODelay" module has it's own register space that is independent
of the control module and the padconf register area.

With recent changes to the pinctrl framework, we can now support
this hardware with a reasonably minimal driver by using #pinctrl-cells,
GENERIC_PINCTRL_GROUPS and GENERIC_PINMUX_FUNCTIONS.

It is advocated strongly in TI's official documentation considering
the existing design of the DRA7 family of processors during mux or
IODelay reconfiguration, there is a potential for a significant glitch
which may cause functional impairment to certain hardware. It is
hence recommended to do as little of muxing as absolutely necessary
without I/O isolation (which can only be done in initial stages of
bootloader).

NOTE: with the system wide I/O isolation scheme present in DRA7 SoC
family, it is not reasonable to do stop all I/O operations for every
such pad configuration scheme. So, we will let it glitch when used in
this mode.

Even with the above limitation, certain functionality such as MMC has
mandatory need for IODelay reconfiguration requirements, depending on
speed of transfer. In these cases, with careful examination of usecase
involved, the expected glitch can be controlled such that it does not
impact functionality.

In short, IODelay module support as a padconf driver being introduced
here is not expected to do SoC wide I/O Isolation and is meant for
a limited subset of IODelay configuration requirements that need to
be dynamic and whose glitchy behavior will not cause functionality
failure for that interface.

IMPORTANT NOTE: we take the approach of keeping LOCK_BITs cleared
to 0x0 at all times, even when configuring Manual IO Timing Modes.
This is done by eliminating the LOCK_BIT=1 setting from Step
of the Manual IO timing Mode configuration procedure. This option
leaves the CFG_* registers unprotected from unintended writes to the
CTRL_CORE_PAD_* registers while Manual IO Timing Modes are configured.

This approach is taken to allow for a generic driver to exist in kernel
world that has to be used carefully in required usecases.

5bb61d14b9 Docs: dt: Be explicit and consistent in reference to IOMMU specifiers
The generic IOMMU binding says that the meaning of an 'IOMMU specifier'
is defined by the binding of a specific SMMU.  The ARM SMMU binding
never explicitly uses the term 'specifier' at all.  Update implicit
references to use the explicit term.

In the iommu-map binding change references to iommu-specifier to
"IOMMU specifier" so we are 100% consistent everywhere with terminology
and capitalization.
