The ID pin is indeed PH4. The PD2 pin can be used to switch power
on/off for the USB Type A receptacle on pcDuino2, but it has nothing
to do with the MicroUSB OTG receptacle. The VBUS pin of the MicroUSB
receptacle is always connected to 5V according to the schematics
(both pcDuino1 and pcDuino2) and confirmed by doing some tests on
pcDuino2. The PH5 pin is just one of the pins on the J8 expansion

up and connected to the N_VBUSEN pin of AXP209 PMIC, while the
VBUS pin of AXP209 only has a capacitor between it and the
ground (this pin is not used for anything else).
To sum it up. Only the ID pin (PH4) has a real use. And 5V voltage
is always served to the MicroUSB OTG receptacle no matter what is
the state of the PB9/PD2 pins.
This patch has been tested on pcDuino2 to work fine in a host role

ARM: dts: sun4i: Allow to use the PH6 pin for GPIO on pcDuino1/2
The pcDuino1 board does not use any power switches at all for its
two USB host ports and the VBUS pins are always connected to 5V.
The pcDuino2 board uses the RT9701GB power switch for its single
USB host port, but the USB_EN pin (PD2) is pulled up with a 10K
resistor. So that the USB power is still enabled by default,
resulting in the same behaviour as pcDuino1 if nobody touches
the PD2 pin. This minor difference is going to be handled in a
follow-up patch, introducing a separate dts file for pcDuino2.
The primary reason for this fix is that the current dts file
unnecessarily meddles with the PH3 and PH6 pins. But the PH6 pin
is available on the Arduino-compatible expansion header and may
have a better use for other purposes. This patch fixes the
problem and now the PH6 pin can be used with the GPIO sysfs
interface. Tested on a pcDuino2 board with a multimeter:
echo 230 > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio230/direction
echo 0 > /sys/class/gpio/gpio230/value
echo 1 > /sys/class/gpio/gpio230/value

ARM: dts: sun5i: Add dts file for q8 formfactor a13 based tablets
This commits adds a generic dts file for q8 formfactor a13 based tablets.
The tablets ship in many variants, with the difference mainly being the
touchscreen controller / accelerometer / wifi chip used.
The wifi is USB based, and thus not listed in devicetree.
The touchscreen controller / accelerometer may turn out to be a problem
once we add support for those. We can either do something with devicetree
overlays, or add sun5i-a13-<touchscreen>-<accelerometer>.dts files. The
latter is what the android mod community is doing with firmware images.
This dts was tested with an a13 q8 tablet with a pcb labelled: "94V-0",
silead gsl1680 touchscreen controller and a mc32x0 accelerometer.

blk: rq_data_dir() should not return a boolean
rq_data_dir() returns either READ or WRITE (0 == READ, 1 == WRITE), not
a boolean value.
Now, admittedly the "!= 0" doesn't really change the value (0 stays as
zero, 1 stays as one), but it's not only redundant, it confuses gcc, and
causes gcc to warn about the construct
switch (rq_data_dir(req)) {
case READ:
...
case WRITE:
...
that we have in a few drivers.
Now, the gcc warning is silly and stupid (it seems to warn not about the
switch value having a different type from the case statements, but about
_any_ boolean switch value), but in this case the code itself is silly
and stupid too, so let's just change it, and get rid of warnings like
this:
drivers/block/hd.c: In function ‘hd_request’:
drivers/block/hd.c:630:11: warning: switch condition has boolean value [-Wswitch-bool]
switch (rq_data_dir(req)) {
The odd '!= 0' came in when "cmd_flags" got turned into a "u64" in
commit
5953316dbf90 ("block: make rq->cmd_flags be 64-bit") and is
presumably because the old code (that just did a logical 'and' with 1)
would then end up making the type of rq_data_dir() be u64 too.
But if we want to retain the old regular integer type, let's just cast
the result to 'int' rather than use that rather odd '!= 0'.

writeback: plug writeback in wb_writeback() and writeback_inodes_wb()
We had to revert the pluggin in writeback_sb_inodes() because the
wb->list_lock is held, but we could easily plug at a higher level before
taking that lock, and unplug after releasing it. This does that.
Chris will run performance numbers, just to verify that this approach is
comparable to the alternative (we could just drop and re-take the lock
around the blk_finish_plug() rather than these two commits.
I'd have preferred waiting for actual performance numbers before picking
one approach over the other, but I don't want to release rc1 with the
known "sleeping function called from invalid context" issue, so I'll
pick this cleanup version for now. But if the numbers show that we
really want to plug just at the writeback_sb_inodes() level, and we
should just play ugly games with the spinlock, we'll switch to that.

thermal: fix intel PCH thermal driver mismerge
I didn't notice this when merging the thermal code from Zhang, but his
merge (commit
5a924a07f882: "Merge branches 'thermal-core' and
'thermal-intel' of .git into next") of the thermal-core and
thermal-intel branches was wrong.
In thermal-core, commit
17e8351a7739 ("thermal: consistently use int for
temperatures") converted the thermal layer to use "int" for
temperatures.
But in parallel, in the thermal-intel branch commit
d0a12625d2ff
("thermal: Add Intel PCH thermal driver") added support for the intel
PCH thermal sensor using the old interfaces that used "unsigned long"
pointers.
This resulted in warnings like this:
drivers/thermal/intel_pch_thermal.c:184:14: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
.get_temp = pch_thermal_get_temp,
^
drivers/thermal/intel_pch_thermal.c:184:14: note: (near initialization for ‘tzd_ops.get_temp’)

.get_trip_temp = pch_get_trip_temp,

This fixes it.
