Commit 6aa85a5ae610106d89e50c7e1f760c56d12f9bc4 (omap4: 4430sdp:
enable the ehci port on 4430SDP) added code to enable EHCI
support on 4430sdp board.
Looks like the ULPI pin does not seem to be muxed properly on ES1.0
SDP and this causes the system to reboot when the ULPI PHY is
enabled.
Fix this by muxing the pin, this is the same setting for
both ES1.0 and ES2.0. Also add checking for gpio_request.

TFP410 DVI chip is used to provide display out.
This chip is controlled by 2 lines:
LDO which supplies the power is controlled over gpio + 2
and the enable of the chip itself is done over gpio + 1
NOTE: the LDO is necessary for LED, serial blocks as well.
gpio + 1 was used to sense USB overcurrent in vanilla beagle.
Without this fix, the display would not function as the LDO
remains shut down.

GPIO reset line for Beagle XM is different from vanilla beagle
so we populate it as part of gpio update routine.
This in part fixes the issue of display not functioning on beagle XM

EHCI enable power pin is inverted (active high) in comparison
to vanilla beagle which is active low. Handle this case conditionally.
Without this fix, Beagle XM 4 port EHCI will not function and no
networking will be available

The second MMC channel (used by the WLAN/BT module) is not linked to
power regulator. This causes the WLAN/BT module to fail being detected if
CONFIG_REGULATOR_DUMMY is not set.
This patch adds the two regulators that actually feed the WLAN/BT module
(1v8 from the TWL4030 VIO LDO, and a fixed 3v3). With that patch, the
second channel is properly detected.
Also change vmmc1 to use symbolic names instead of direct device
reference.

The SMSC 3320 USB PHY on the OMAP4 Pandaboard needs a 19.2 MHz
reference clock. This clock is provided from the OMAP4's fref_clk3
pad.
Recent changes to clock44xx_data.c made the clock framework aware
of the existence of these fref_clk[i] lines. If the option
CONFIG_OMAP_RESET_CLOCKS is enabled in the kernel, then the
clock framework will turn these clocks off during bootup.
Explicitly request and keep this clock enabled at init for the
Pandaboard, so that the PHY receives this clock at all times.

Instead of accessing the irq_desc array directly
we can use irq_to_desc(irq). That will allow us to,
if wanted, select SPARSE_IRQ and irq_descs will be
added to a radix tree, instead of a array.

In case on OMAP2+ we call set_24xx_gpio_triggering() instead of
updating reg and l values. However, at the end of the function we
perform a write:
__raw_writel(l, reg);
So on OMAP2+ we end up writing 0 to the bank->base which is not
correct (typically this points to GPIO_REVISION register).
Fix this by returning immediately after call to
set_24xx_gpio_triggering().

omap_enable_smartreflex_on_init is meant to be used by boards
which would like to have SR enabled by default on the platform, while
omap_devinit_smartreflex is used by pm code, the protos are defined
in pm.h. This header should be included to ensure that sr_device
function definitions match the prototypes.
including pm.h fixes the sparse warnings (with CONFIG_OMAP_SMARTREFLEX=y):

After reordering the sequence of relocating objects, commit 6fe4f1404,
we can no longer rely on seeing all reloc targets prior to performing
the relocation. As a result we were ignoring the need to flush objects
from the render cache and invalidate the sampler caches, resulting in
rendering glitches. So we need to clear the relocation domains earlier.

On the fault path, commit 6fe4f140 introduction a regression whereby it
changed the sequence of the objects but continued to use the original
ordering of relocation entries. The result was that incorrect GTT offsets
were being fed into the execbuffer causing lots of misrendering and
potential hangs.

Whilst we had no older batches on the active list, everything was fine.
However, if the GPU is free running and the requests are only being
reaped by the periodic retirer, than the current seqno may not be at the
start of the list. In this case we need to select the first batch after
the last seqno written by the gpu and not inclusive of the seqno.

The PCI sysfs ROM interface requires an enabling write to access the ROM
image, but the default file mode is 0400. The original proposed patch
adding sysfs ROM support was a true read-only interface, with the
enabling bit coming in as a feature request. I suspect it was simply an
oversight that the file mode didn't get updated to match the API.

This functionality is known to be incomplete, so discourage its use in
general-purpose kernels.
The only reason to use this driver is to support PCI hotplug on CNB20LE-
based machines that don't have ACPI, and there are very few such
systems.

The broadcom_bus.c quirk was written (without benefit of documentation)
to support PCI hotplug on an old system that doesn't have ACPI. As
such, we should only use it when the system doesn't have ACPI.
If the system does have ACPI and we need the host bridge description, we
should get it from the ACPI _CRS method. On machines older than 2008,
we currently ignore _CRS, but that doesn't mean we should use
broadcom_bus.c. It means we should either (a) do what we've done in the
past and assume everything in the PCI gap is routed to bus 0 (so hotplug
may not work), or (b) arrange to use _CRS. This patch does (a).

Move the evaluation of acpi_pci_osc_control_set() (to request control of

Additionally, check if all of the requisite _OSC support bits are set

This patch enables pci=bfsort by default on future Dell systems.
It reads SMBIOS type 0xB1 vendor specific record and sets pci=bfsort
accordingly.
Offset Name Length Value Description
04 Flags0 Word Varies Bits 9-10
- 10:9 = 00 Unknown
- 10:9 = 01 Breadth First
- 10:9 = 10 Depth First
- 10:9 = 11 Reserved
1. Any time pci=bfsort has to be enabled on a system, we need to add the
model number of the system to the white list. With this patch, that
is not required.
2. Typically, model number has to be added to the white list when the
system is under development. With this change, that is not required.

I noticed that PCI Express PMEs don't work on my Toshiba Portege R500
after the system has been woken up from a sleep state by a PME
(through Wake-on-LAN). After some investigation it turned out that
the BIOS didn't clear the Root PME Status bit in the root port that
received the wakeup PME and since the Requester ID was also set in
the port's Root Status register, any subsequent PMEs didn't trigger
interrupts.
This problem can be avoided by clearing the Root PME Status bits in
all PCI Express root ports during early resume. For this purpose,
add an early resume routine to the PCIe port driver and make this
driver be always registered, even if pci_ports_disable is set (in
which case the driver's only function is to provide the early
resume callback).
