Remove SoC dependency and make it generic for every Atmel ARM AT91. That will
allow to select this driver for newer chips. Keep dependency on AT91 because of
the use of an header file located in include/mach directory.
Modify the comment to reflect this.

Now that we are using irqdomains, we need to convert GPIO pins to Linux
IRQ numbers using the gpio_to_irq() function.

Since SDIO drivers may want to do some SDIO operations in their suspend
callback functions, we must not keep the host claimed when calling them.

Now, dma_ops is assumed that use the IDMAC. But if dma_ops is assigned
the pdata->dma_ops, we didn't ensure that callback function is defined.
If the callback isn't defined, then we should run in PIO mode.

Commit c79396c191bc19 ("mmc: sdhci: prevent card detection activity
for non-removable cards") disables card detection where the cards
are marked as non-removable.
This makes sense, but the implementation detail of calling
mmc_card_is_removable() causes some problems, because
mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME
semantics.
In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root
filesystem is stored on SD, but we also have external SD card slots
where we want automatic card detection.
Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE,
which is defined to mean that the card is *really* nonremovable. This
could be revisited in future if we find a way to improve
CONFIG_MMC_UNSAFE_RESUME semantics.

When dw_mci_pre_dma_transfer returns failure in some reasons,
dw_mci_submit_data will prepare to switch the PIO mode from DMA.
After switching to PIO mode, DMA(IDMAC in particular) is still
enabled. This makes the corruption in handling interrupt and
the driver lock-up.

MMC bus is using legacy suspend/resume method, which is not compatible if
runtime pm callbacks are used. In this scenario, MMC bus suspend/resume
callbacks cannot be called when system entering S3. So change to use the
new defined dev_pm_ops for system sleeping mode.

of_have_populated_dt() is not expected to be used in drivers but
instead only in early platform init code.
Drivers on the other hand should rely on dev->of_node or of_match_device().
Besides usage of of_have_populated_dt() also throws up build error as below
which was reported by Balaji TK, when omap_hsmmc is built as a module.
ERROR: "allnodes" [drivers/mmc/host/omap_hsmmc.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
So get rid of all of_have_populated_dt() usage in omap_hsmmc driver and
instead use dev->of_node to make the same dicisions as earlier.

eMMC v4.5 sanitize operation erases all copies of unmapped

to unmap the required sectors. That was not being done.

eMMC v4.5 discard operation is significantly different from the
existing trim operation because it is not guaranteed to work with
the new sanitize operation. Consequently mmc_can_trim() is
separated from mmc_can_discard().
Also the new discard operation does not result in the sectors being
set to all-zeros, so discard_zeroes_data must not be set.
In addition, the new discard has the same timeout as trim, but from
v4.5 trim is defined to use the hc timeout. The timeout calculation
is adjusted accordingly.
Fixes apply to linux 3.2 on.

Rather than loading firmware specific for the xtal frequency, just use
the standard firmware and set the xtal frequency after firmware upload.
The modified firmware will never be released, so we're better off
merging this now rather than waiting for v3.5.

There are some softwares (Kaffeine and likely xine) that uses a
DVBv5 call to switch to DVB-S2, but expects that a DVBv3 call to
switch back to DVB-S. Well, this is not right, as a DVBv3 call
doesn't know anything about delivery systems.
However, as, by accident, this used to work, we need to restore its
behavior, in order to avoid regressions with those softwares.

Assumption that irq numbers of asic3 gpios start at
IRQ_BOARD_START is certainly wrong - driver may as well
use any other base for its irqs (consider for example
the imaginary case of two ASIC3 chips onboard)
Furthermore, some platforms even don't have IRQ_BOARD_START
defined, so driver will fail to build on them:
-------------------------------------------------------
drivers/mfd/asic3.c: In function 'asic3_gpio_to_irq':
drivers/mfd/asic3.c:530: error: 'IRQ_BOARD_START' undeclared (first use in this function)
drivers/mfd/asic3.c:530: error: (Each undeclared identifier is reported only once
drivers/mfd/asic3.c:530: error: for each function it appears in.)
-------------------------------------------------------
Fix it by using irq_base from driver data.

It is observed that the echi ports of 3430 sdp board
are not working due to the random timing of programming
the associated GPIOs of the ULPI PHYs of the EHCI for reset.
If the PHYs are reset at during usbhs core driver, host ports will
not work because EHCI driver is loaded after the resetting PHYs.
The PHYs should be in reset state while initializing the EHCI
controller.
The code which does the GPIO pins associated with the PHYs
are programmed to reset is moved from the USB host core driver
to EHCI driver.

This continues the theme started with vm_brk() and vm_munmap():
vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.
This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have
to export our internal do_mmap_pgoff() function.
Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead. We're actually
very close to that already, with the notable exception of the (broken)
use in i810, and a couple of stragglers in binfmt_elf.

does the VM locking for the caller.

This driver anticipates pch_uart_verify_port() is not called
during installation.
However, actually pch_uart_verify_port() is called during
installation.
As a result, memory access violation occurs like below.
0. initial value: use_dma=0
1. starup()
- dma channel is not allocated because use_dma=0
2. pch_uart_verify_port()
- Set use_dma=1
3. UART processing acts DMA mode because use_dma=1
- memory access violation occurs!
This patch fixes the issue.
Solution:
Whenever pch_uart_verify_port() is called and then
dma channel is not allocated, the channel should be allocated.

This patch (as1544) fixes a problem affecting some EHCI controllers.
They can generate interrupts whenever the STS_FLR status bit is turned
on, even though that bit is masked out in the Interrupt Enable
register.
Since the driver doesn't use STS_FLR anyway, the patch changes the
interrupt routine to clear that bit whenever it is set, rather than
leaving it alone.

This patch (as1542) changes the criterion ehci-hcd uses to tell when
it needs to resume the controller's root hub. A resume is needed when
a port status change is detected, obviously, but only if the root hub
is currently suspended.
Right now the driver tests whether the root hub is running, and that
is not the correct test. In particular, if the controller has died
then the root hub should not be restarted. In addition, some buggy
hardware occasionally requires the root hub to be running and
sending out SOF packets even while it is nominally supposed to be
suspended.
In the end, the test needs to be changed. Rather than checking whether
the root hub is currently running, the driver will now check whether
the root hub is currently suspended. This will yield the correct
behavior in all cases.

These devices have a number of non serial interfaces as well. Use
the existing "Direct IP" blacklist to prevent binding to interfaces
which are handled by other drivers.
We also extend the "Direct IP" blacklist with with interfaces only
seen in "QMI" mode, assuming that these devices use the same
interface numbers for serial interfaces both in "Direct IP" and in
"QMI" mode.
