Add support for optional devicetree property 'timeout-sec'.
'timeout-sec' is used in the driver if specified in devicetree.
Otherwise, fall back to driver default, i.e., 60 seconds

ish_dev_init() allocates 512*176 bytes memory for tx_buf and stores it at
&dev->wr_free_list_head.link list on ish_probe().
But there is no deallocation of this memory in ish_remove() and in
ish_probe() error path.
So current intel-ish-ipc provides 88 KB memory leak for each
probe/release.
The patch replaces kzalloc allocation by devm_kzalloc and removes
ishtp_device *dev deallocation by kfree.

On Mehlow Xeon-E workstation, ISH PCI device is enabled but without ISH
firmware. Here the ISH device PCI device id was reused for some non Linux
storage drivers. So this was not done for enabling ISH. But this has a
undesirable side effect for Linux.
Here the ISH driver will be loaded via PCI enumeration and will try to do
reset sequence. But reset sequence will wait till timeout as there is no
real ISH firmware is present to take action. This delay will add to boot
time of Linux (This platform will still continue to boot after this
timeout).
To avoid this boot delay we need to prevent loading of ISH drivers on
this platform. So we need to have hack to avoid treating this device as
ISH on this platform. To identify this workstation, we need some runtime
method. Luckily there are special PCI id on this workstation to
distinguish from the client version of this platform. On client version,
the ISH is supported using same PCI device id. So this change look for
the presence of PCI device IDs A309 and A30A and exit.

Usually the format on the source pad is the same as on the sink pad.
However the CSID is able to do some format conversions. To support
this make the format on the source pad selectable amongst a list
of formats. This list can be different for each sink pad format.
This is still not used but will be when the format conversions

Caused by various commits creating erofs in the staging tree interacting
with various commits redoing the mount infrastructure in the vfs tree.
I have disabed CONFIG_EROFS_FS for now:"
The reason of compiling error is:
Since -next collects and merges developing patches including common vfs
stuff from multi-trees, but those patches didn't cover erofs, such as:
('vfs: Suppress MS_* flag defs within the kernel unless explicitly enabled")
https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git/commit/?h=for-next&id=109b45090d7d3ce2797bb1ef7f70eead5bfe0ff3
("vfs: Require specification of size of mount data for internal mounts")
https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git/commit/?h=for-next&id=0a191e4505a4f255e6513b49426213da69bf0e80
Above vfs related patches has not been merged in staging tree, if we
submit those erofs patches to staging mailing list and after including
them in staging-{test,nexts} tree, it can easily cause compiling error.
We worked out some patches to adjust those vfs change, but now we just
submit them to -next tree temporarily to avoid compiling error.
For potentail conflict in between erofs and vfs changes in incoming
merge window, Stephen suggested that we can disable CONFIG_EROFS_FS
temporarily to pass merge window, and after that we can do restore by
reenabling CONFIG_EROFS_FS and applying those fixing patches. Also
Greg confirmed this solution.
So, let's disable compiling erofs for a while.

The U and V offset macros for planar 4:2:0 (U_OFFSET, V_OFFSET, and

calculated as:
(pix->width * y / 4)
But this does not produce correct offsets for odd values of y (luma
line #). The luma line # must be decimated by two to produce the
correct U/V line #, so the correct formula is:
(pix->width * (y / 2) / 2)

param passed through the gasket layer or from userspace via the

The "type of reset" parameter to the gasket device reset APIs isn't
required by the only gasket device submitted upstream, apex.
The framework documents the param as private to the device driver and a
pass-through at the gasket layer, but the gasket core calls the device
driver with a hardcoded reset type of zero, which is not documented as
having a predefined meaning.
In light of all this, remove the reset type parameter from the
framework. Remove the reset ioctl reset type parameter, and bump the
framework version number to reflect the interface change.

The uio_unregister_device() function assumes that if "info->uio_dev" is
non-NULL that means "info" is fully allocated. Setting info->uio_de
has to be the last thing in the function.
In the current code, if request_threaded_irq() fails then we return with
info->uio_dev set to non-NULL but info is not fully allocated and it can
lead to double frees.
