drivers: misc: ti-st: Use int instead of fuzzy char for callback status

2016-07-17T17:59:26Z

On mips and parisc: drivers/bluetooth/btwilink.c: In function 'ti_st_open': drivers/bluetooth/btwilink.c:174:21: warning: overflow in implicit constant conversion [-Woverflow] hst->reg_status = -EINPROGRESS; drivers/nfc/nfcwilink.c: In function 'nfcwilink_open': drivers/nfc/nfcwilink.c:396:31: warning: overflow in implicit constant conversion [-Woverflow] drv->st_register_cb_status = -EINPROGRESS; There are actually two issues: 1. Whether "char" is signed or unsigned depends on the architecture. As the completion callback data is used to pass a (negative) error code, it should always be signed. 2. EINPROGRESS is 150 on mips, 245 on parisc. Hence -EINPROGRESS doesn't fit in a signed 8-bit number. Change the callback status from "char" to "int" to fix these.

ti-st: use worker instead of calling st_int_write in wake up

2015-09-21T05:52:13Z

The wake up method is called with the port lock held. The st_int_write method calls port->ops->write with tries to acquire the lock again, causing CPU to wait infinitely. Right way to do is to write data to port in worker thread. Signed-off-by: Muhammad Hamza Farooq Signed-off-by: Jacob Siverskog Signed-off-by: Greg Kroah-Hartman

Revert "ti-st: add device tree support"

2015-08-05T20:24:12Z

This reverts commit 46d0d33350e9b32642d745a8b46a954910196b4d. This binding is horrible and never should have been merged. It is not documented nor are there any in tree users, so reverting it will not break anything we care about. Lets revert it before we do have users. The problems with it are: - It is not documented. - The GPIO connection is described with a custom property and uses Linux GPIO numbering. - The UART connection is described using the Linux tty device name.

ti-st: clean up data types (fix harmless memory corruption)

2015-02-03T23:48:51Z

The big issue here is: of_property_read_u32(np, "flow_cntrl", (u32 *)&dt_pdata->flow_cntrl); "->flow_cntrl" is a char so when we write a 32 bit number to it then it corrupts past the end of the char. It's probably hard to notice because the struct has padding so the code works on little endian systems. But on a big endian system the code would fail and on a 64 bit, big endian systems then "nshutdown_gpio" and "baud_rate" would be buggy as well.

ti-st: add device tree support

2015-01-12T13:04:10Z

When using device tree, driver configuration data need to be read from device node. Add support for getting the platform data information from the device tree information stored in the .dtb file in case it exists.

drivers:misc:ti-st: platform hooks for chip states

2011-08-22T21:13:32Z

Certain platform specific or Host-WiLink Interface specific actions would be required to be taken when the chip is being enabled and after the chip is disabled such as configuration of the mux modes for the GPIO of host connected to the nshutdown of the chip or relinquishing UART after the chip is disabled. Similar actions can also be taken when the chip is in deep sleep or when the chip is awake. Performance enhancements such as configuring the host to run faster when chip is awake and slower when chip is asleep can also be made here.
