====================
pull-request: wireless-drivers-next 2016-07-22

I'm sick so I have to keep this short, but here's the last pull request
to net-next. This time there's a trivial conflict with mtd tree:

http://lkml.kernel.org/g/20160720123133.44dab209@canb.auug.org.au

We concluded with Brian (CCed) that it's best that we ask Linus to fix
this. The patches have been in linux-next for a couple of days. This
time I haven't done any merge tests so I don't know if there are any
other conflicts etc.

Please let me know if there are any problems.

e16b466059 PCI: Allow additional bus numbers for hotplug bridges
A user may hot add a switch requiring more than one bus to enumerate.  This
previously required a system reboot if BIOS did not sufficiently pad the
bus resource, which they frequently don't do.

Add a kernel parameter so a user can specify the minimum number of bus
numbers to reserve for a hotplug bridge's subordinate buses so rebooting
won't be necessary.

The default is 1, which is equivalent to previous behavior.

9e60f50b4a dt-bindings: pwm: Add binding for ChromeOS EC PWM
The ChromeOS Embedded Controller can support controlling its attached
PWMs via its host-command interface. The number of supported PWMs varies
on a per-board basis, but we can autodetect this by checking the error
codes, so we don't need an extra property for this. And because the EC
only allows specifying the duty cycle and not the period, we don't
specify the period via pwm-cells, and instead have only support for one
cell -- to specify the index.

110754563c Documentation: phy: Let the rockchip eMMC PHY get an exported card clock
As of an earlier change in this series ("Documentation: mmc:
sdhci-of-arasan: Add ability to export card clock") the SDHCI driver
used on Rockchip SoCs can now expose its clock.  Let's now specify that
the PHY can use it.

Letting the PHY get access to this clock means it can adjust
phyctrl_frqsel field appropriately.  Although the Rockchip PHY appears
slightly different than the reference Arasan one, you can see that the
Arasan datasheet [1] had it defined as:
  Select the frequency range of DLL operation:
  3b'000 => 200MHz to 170 MHz
  3b'001 => 170MHz to 140 MHz
  3b'010 => 140MHz to 110 MHz
  3b'011 => 110MHz to 80MHz
  3b'100 => 80MHz to 50 MHz
  3b'101 => 275Mhz to 250MHz
  3b'110 => 250MHz to 225MHz
  3b'111 => 225MHz to 200MHz

On the Rockchip version of the PHY we have less granularity but the idea
is the same.

6db90c5976 Documentation: mmc: sdhci-of-arasan: Add ability to export card clock
Some SD/eMMC PHYs (like the PHY from Arasan that is designed to work
with arasan,sdhci-5.1) need to know the card clock frequency in order to
function properly.  Physically in a SoC this clock is exported from the
SDHCI IP block to the PHY IP block and the PHY needs to know the speed.
Let's export the SDHCI card clock using a standard device tree mechanism
so that the PHY can get access to it and query the card clock frequency.

6582019927 Documentation: mmc: sdhci-of-arasan: Add soc-ctl-syscon for corecfg regs
As can be seen in Arasan's datasheet [1] there are several "corecfg"
settings in their SDHCI IP Block that are supposed to be controlled by
software.  Although the datasheet referenced is a bit vague about how to
access corecfg, in Figure 5 you can see that for Arasan's PHY (a
separate component than their SDHCI component) they describe the
"phyctrl" registers as being "FROM SOC CTL REG", implying that it's up
to the licensee of the Arasan IP block to implement these registers.  It
seems sane to assume that the "corecfg" registers in their SDHCI IP
block works in a similar way for all licensees of the IP Block.

Device tree has a model that allows a device to get a reference to
random registers located elsewhere in the SoC: sysctl.  Let's leverage
this model and allow adding a sysctl reference to access the control
registers for the Arasan SDHCI PHYs.

Having a reference to the control registers doesn't do much for us on
its own since the Arasan spec doesn't specify how these corecfg values
are laid out in memory.  In the SDHCI driver we'll need a map detailing
where each corecfg can be found in each implementation.  This map can be
found using the primary compatible string of the SDHCI device.  In that
spirit, document that existing rk3399 device trees already have a
specific compatible string, though up to now they've always been relying
on the driver supporting the generic.

Note that since existing devices seem to work fairly well as-is, we'll
list the syscon reference as "optional", but it's likely that we'll run
into much fewer problems if we can actually set the proper values in the
syscon, so it is strongly suggested that any SoCs where we have a map to
set the corecfg also include a reference to the syscon.
