Resending - Since I'm not sure the first mail was went through.
This time adding a patch from Matthias Kaehlcke.
Greg,
Please find attached the patch-set which fixes/updates the WiLink shared
transport driver hosted at drivers/misc/ti-st/
Among the following set of patches:-
The gpio handling patch, disabling chip upon firmware download timeout &
fixing the read fw version command comes from testing the driver on various
platforms with a variety of serial driver working underneath.
The other 2 patches comes in form of removing sparse warnings and a nicer
update from existing wait for completion usage.
Matthias Kaehlcke (1):
drivers/misc/ti-st: check chip_awake NULL check
Pavan Savoy (5):
drivers/misc/ti-st: remove gpio handling
drivers/misc/ti-st: remove sparse warnings
drivers/misc/ti-st: chip_disable on timeout
drivers/misc/ti-st: use cpu friendly completions
drivers/misc/ti-st: fix read fw version cmd

From: Pavan Savoy <pavan_savoy@ti.com>
A platform hook to enable/disable the chip was introduced to perform specific
activities to power-up and power-down the WL chip.
Moving the power-up/down sequence also there makes more sense, since different
platforms have begun to have their own ways to power-up/down the chip.
This patch removes all of the gpio handling done by the driver in
st_kim_start/st_kim_stop & any of the gpio request done in the probe function.

If the communication with the WiLink breaks down for whatever reasons & the
ti-st driver is unable to un-install the line-discipline during clean-up in
st_kim_stop, the GPIO should be held low (BT_EN=0) & the platform's chip
disable hook shall also be called.

Be nice to CPU and don't hog the resources, use a nice wait_for_interruptible
timeout for completions instead of wait_for_timeout which is
non-interruptible.

If the read firmware version response from the chip is split into multiple
frames of UART buffer being received by the host, the TI-ST driver as of today
is unable to put the pieces of response together unlike other responses.

Before calling on any of the platform hooks, shared transport driver checks
for the validity of the platform hooks as to whether it is provided or not.
A wrong function was being checked for, before the chip_awake hook was called
by the HCI-LL sleep logic handler. This patch corrects the check.
