mei: me: clear interrupts on the resume path
mei: nfc: fix nfc device freeing
mei: init: Flush scheduled work before resetting the device
|

We need to clear pending interrupts on the resume
path. This brings the device into defined state
before starting the reset flow
This should solve suspend/resume issues:
mei_me : wait hw ready failed. status = 0x0
mei_me : version message write failed

The nfc_dev is a static variable and is not cleaned properly upon reset

Flushing pending work items before resetting the device makes more
sense than doing so afterwards. Some of them, like e.g. the NFC
initialization one, find themselves with client IDs changed after
the reset, eventually leading to trigger a client.c:mei_me_cl_by_id()
warning after a few modprobe/rmmod cycles.

ERROR: "memcpy_fromiovec" [drivers/vhost/vhost_scsi.ko] undefined!
That function is only present with CONFIG_NET. Turns out that
crypto/algif_skcipher.c also uses that outside net, but it actually
needs sockets anyway.
In addition, commit 6d4f0139d642c45411a47879325891ce2a7c164a added
CONFIG_NET dependency to CONFIG_VMCI for memcpy_toiovec, so hoist
that function and revert that commit too.
socket.h already includes uio.h, so no callers need updating; trying
only broke things fo x86_64 randconfig (thanks Fengguang!).

This driver requests and remaps a memory region as configured in the
device tree. It serves memory from this region via the genalloc API. It
optionally enables the SRAM clock.
Other drivers can retrieve the genalloc pool from a phandle pointing to
this drivers' device node in the device tree.
The allocation granularity is hard-coded to 32 bytes for now, to make the
SRAM driver useful for the 6502 remoteproc driver. There is overhead for
bigger SRAMs, where only a much coarser allocation granularity is needed:
At 32 bytes minimum allocation size, a 256 KiB SRAM needs a 1 KiB bitmap
to track allocations.

This driver was merged in 2.6.38 but never actually compiled because
it depends on the <mach/pcie.h> header that has not made it into the
kernel. Starting with Linux-3.10, this results in "allyesconfig"
build errors, since spear13xx can now be enabled with the default
"multiplatform" platform on ARM. Let's mark it as broken for now.
If it doesn't get fixed, we can drop it completely.

The apds9802als driver implements runtime pm and at the same time uses the
legacy pm callbacks for suspend and resume. This does not work since the i2c
core wont look at the legacy pm callbacks if a driver has the 'pm' field set.
This patch fixes it by moving over to dev_pm_ops for suspend/resume as well.
Since both runtime pm and suspend/resume behave the same way this can easily be
done using the UNIVERSAL_DEV_PM_OPS macro.

It should be left to the drivers to enable and disable the device on the
MEI bus when e.g getting probed.
For drivers to be able to safely call the enable and disable hooks, the
mei_cl_ops must be set before it's probed and thus this should happen
before registering the device on the MEI bus. Hence the mei_cl_add_device()
prototype change.

Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.

The CS5535/CS5536 MFGPT has no support to reset the device.
The current method uses an undocumented bit but does not work on all
devices. At least on my ALIX board it completely freezes the board.
This new method tries to soft reset all timers by unconfiguring them.
But this does not clear the RO setup register and therefore it has to
be ignored while probing.
Resetting the timers is not only needed on broken BIOSes also when
kexec is used. Otherwise the new kernel will find preconfigured timers
and odd things will happen.

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SET_SYSTEM_SLEEP_PM_OPS are only used
when the CONFIG_PM_SLEEP is enabled.
