Input: iforce - add sanity checks

2019-08-06T16:10:57+00:00

The endpoint type should also be checked before a device
is accepted.

Input: iforce - remove empty multiline comments

2019-07-15T16:43:13+00:00

Those are remnants of the SPDX identifier migration, which haven't been
removed properly.

Merge tag 'v5.2' into next

2019-07-15T16:42:32+00:00

Sync up with mainline to resolve conflicts in iforce driver.

Input: iforce - add the Saitek R440 Force Wheel

2019-06-23T06:55:50+00:00

This is added based on the fact that this is an iforce-based device and
that the Windows driver for the R440 works for the Logitech WingMan Formula
Force after replacing the device/vendor IDs.

Input: iforce - use unaligned accessors, where appropriate

2019-06-23T06:55:49+00:00

Instead of open-coding conversion from/to little-endian, let's
use proper accessors.

Input: iforce - drop couple of temps from transport code

2019-06-23T06:55:49+00:00

Transport initialization code now deals mostly with transport-specific
data, so we can drop couple of temporary variables.

Input: iforce - drop bus type from iforce structure

2019-06-23T06:55:48+00:00

It is not needed anymore as behavior is controlled by the transport
operations set up for given device.

Input: iforce - use DMA-safe buffores for USB transfers

2019-06-23T06:55:48+00:00

USB transport has to use cache line-aligned buffers for transfers to avoid
DMA issues; serio doe snot have such restrictions. Let's move "data_in"
buffer from main driver structure into transport modules and make sure USB
requirements are respected.

Input: iforce - allow callers supply data buffer when fetching device IDs

2019-06-23T06:55:23+00:00

We want to move buffer handling into transport layers as the properties of
buffers (DMA-safety, alignment, etc) are different for different
transports. To allow this, let's allow caller to specify their own buffers
for the results of iforce_get_id_packet() and let transport drivers to
figure what buffers they need to use for transfers.

Input: iforce - only call iforce_process_packet() if initialized

2019-06-23T06:55:23+00:00

It is excessive to check if device is fully initialized in
iforce_process_packet(), as for USB-conected devices we do not start
collecting reports until the device is fully initialized.

Let's change serio transport code to not call iforce_process_packet()
until device initialization is done.
