drivers/misc/ti-st: check chip_awake NULL check

2012-08-16T17:11:45+00:00

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.

drivers/misc/ti-st: fix read fw version cmd

2012-08-16T17:11:45+00:00

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.

drivers/misc/ti-st: use cpu friendly completions

2012-08-16T17:11:45+00:00

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.

drivers/misc/ti-st: chip_disable on timeout

2012-08-16T17:11:45+00:00

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.

drivers/misc/ti-st: remove sparse warnings

2012-08-16T17:11:45+00:00

remove sparse warnings by assigning right storage specifiers to functions and
also clean-up the declarations in the include/linux/ti_wilink_st.h

drivers/misc/ti-st: remove gpio handling

2012-08-16T17:11:45+00:00

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.

MISC: convert drivers/misc/* to use module_platform_driver()

2012-01-25T00:31:48+00:00

This patch converts the drivers in drivers/misc/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

drivers:misc: ti-st: DEBUG uart, baud rate mods

2012-01-04T23:21:04+00:00

To debug different UARTs at different baud-rates connected to the WiLink
connectivity combo-chipset, this patch enables the debugging code so that upon
boot different UARTs at different baud-rates can be tried out to verify the
interface with WiLink.

drivers:misc: ti-st: flush UART upon fw failure

2012-01-04T23:21:04+00:00

Upon failure to read firmware version from chip or upon failure in responses
to firmware download the UART needs to be flushed of its existing buffers so
that the UIM can restart UART properly.
