Add a new driver to support the AB8500 Power Management chip, replacing
the current AB4500. The new driver replaces the old one, instead of an
incremental modification, because this is a substantial overhaul
including:
- Split of the driver into -core and -spi portions, to allow another
interface layer to be added
- Addition of interrupt support
- Switch to MFD core API for handling subdevices
- Simplification of the APIs to remove a redundant block parameter
- Rename of the APIs and macros from ab4500_* to ab8500_*
- Rename of the files from ab4500* to ab8500*
- Change of the driver name from ab4500 to ab8500

The rdc321x southbridge PCI device has no MEM PCI resources that we could
pass to mfd_add_devices. Since 33254dd5, mfd_add_device checks for the
mem_base argument that we set to NULL. Changing the resources passed to
our MFD cells from IORESOURCE_MEM to IORESOURCE_IO fixes that. Since we use
those resources as offsets to the PCI configuration space base address of
the southbridge device this is also more adequate.

Analog Baseband chips. The register access functions are moved

can keep their interface intact when chip infrastructure and

The charger interrupts on the WM831x are unconditionally a wake source
for the system. If the power driver is not able to monitor them (for
example, due to the IRQ line not having been wired up on the system)
then any charger interrupt will prevent the system suspending for any
meaningful amount of time since nothing will ack them.
Avoid this issue by manually acknowledging these interrupts when we
suspend the WM831x core device if they are masked. If software is
actually using the interrupts then they will be unmasked and this
change will have no effect.

Currently completion of WM831x AUXADC conversions is monitored by
checking for convertor enable. Due to the mechanism used to ensure
data corruption is avoided when reading AUXADC data there may under
heavy I/O be a window where this bit has cleared but the conversion
results have not been updated. Data availability is only guaranteed
after the AUXADC data interrupt has been asserted.
Avoid this by always using the interrupt to detect completion. If the
chip IRQ is not set up then we poll the IRQ status register for up to
5ms. If it is set up then we rely on the data done interrupt with a
vastly increased timeout, failing the conversion if the interrupt is
not generated.
This also saves a register read when using interrupts.

When the user passes the kernel parameter acpi_enforce_resources=lax,
the ACPI resources are no longer protected, so a native driver can
make use of them. In that case, we do not want the asus_atk0110 to be
loaded. Unfortunately, this driver loads automatically due to its
MODULE_DEVICE_TABLE, so the user ends up with two drivers loaded for

st_open() suggests that llseek() doesn't work: "We really want to do
nonseekable_open(inode, filp); here, but some versions of tar incorrectly
call lseek on tapes and bail out if that fails. So we disallow pread()
and pwrite(), but permit lseeks."
Instead of using the fallback default_llseek() the driver should use
noop_llseek() which leaves the file->f_pos untouched but succeeds.

A few architectures, like OMAP, allow you to set a debouncing time for the
gpio before generating the IRQ. Teach gpiolib about that.
Mark said:
: This would be generally useful for embedded systems, especially where
: the interrupt concerned is a wake source. It allows drivers to avoid
: spurious interrupts from noisy sources so if the hardware supports it
: the driver can avoid having to explicitly wait for the signal to become

David said:

:
: One thing to watch out for is just how variable the hardware capabilities

SDIO specification allows RAW (Read after Write) operation using
IO_RW_DIRECT command (CMD52) by setting the RAW bit. This operation is
similar to ordinary read/write commands, except that both write and read
are performed using single command/response pair. The Linux SDIO layer
already supports this internaly, only external function is missing for
drivers to make use, which is added by this patch.
This type of command is required to implement proper power save mode
support in wl1251 wifi driver.
Android has similar patch for G1 in it's tree for the same reason:

Even though many mmc host drivers pass a pm_message_t argument to
mmc_suspend_host() that argument isn't used the by MMC core. As host
drivers are converted to dev_pm_ops they'll have to construct
pm_message_t's (as they won't be passed by the PM subsystem any more) just
to appease the mmc suspend interface.
We might as well just delete the unused paramter.

Convert PM operations to use dev_pm_ops. This will facilitate the runtime
PM coversion which will add to dev_pm_ops hooks.
Note that dev_pm_ops version of the suspend hook no longer takes a 'state'
argument. However, the MMC core function mmc_suspend_host() still takes a
'state' argument, but it is unused, so a dummy state variable was created
to pass to the MMC core.
In the future, the MMC core should be converted to drop this state
argument and the rest of the MMC drivers could be easily converted to
dev_pm_ops as well.

The following changes were needed:
- do not use in_interrupt() because it will not work
with threaded interrupts
In addition, the following improvements were made:
- ensure DMA is unmapped only after the final DMA interrupt
- ensure a request is completed only after the final DMA interrupt
- disable controller interrupts when a request is not in progress
- remove the spin-lock protecting the start of a new request from
an unexpected interrupt because the locking was complicated and
a 'req_in_progress' flag suffices (since the spin-lock only defers
the unexpected interrupts anyway)
- instead use the spin-lock to protect the MMC interrupt handler
from the DMA interrupt handler
- remove the semaphore preventing DMA from being started while
the previous DMA is still in progress - the other changes make that
impossible, so it is now a BUG_ON condition
- ensure the controller interrupt status is clear before exiting
the interrrupt handler
In general, these changes make the code safer but do not fix any specific
bugs so backporting is not necessary.

Unfortunately some architectures #define their read{b,w,l} and

Atmel-mci support for SDIO interrupts. This adds the enable_sdio_irq()
function and the configuration of sdio irq mask per slot. With this irq
mask information, we keep the idea of multiple slot per sd/mmc host (not
only A and B). MMC_CAP_SDIO_IRQ is added according to slot configuration.
A new little function is added to run mmc_signal_sdio_irq() during

The omap850 and omap730 use 16-bit registers instead of 32-bit, requiring
a modification of the register addresses in the mmc-omap driver. To
resolve this, a bit shift is performed on base register addresses, either
by 1 or 2 bits depending on the CPU in use. This yields the correct
registers for each CPU.
