USB: serial: Remove redundant license text

2017-11-04T10:55:38+00:00

Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

Fix some really minor coding-style issues. Signed-off-by: Johan Hovold

USB: f81232: cleanup non-used define

2015-03-27T16:29:28+00:00

We remove non-used define in this patch to avoid wrong usage. Signed-off-by: Peter Hung Signed-off-by: Johan Hovold

USB: f81232: clarify f81232_ioctl() and fix

2015-03-27T16:29:27+00:00

We extract TIOCGSERIAL section in f81232_ioctl() to f81232_get_serial_info() to make it clarify. Also we fix device type from 16654 to 16550A, and set it's baud_base to 115200 (1.8432MHz/16). Signed-off-by: Peter Hung Signed-off-by: Johan Hovold

USB: f81232: implement set_termios()

2015-03-27T16:29:27+00:00

The original driver had do not any h/w change in driver. This patch implements with configure H/W for baud/parity/word length/stop bits functional in f81232_set_termios(). This patch also implement DTR/RTS control when baudrate B0. We drop DTR/RTS when B0, otherwise enable it. We are checking baudrate in set_termios() too, If baudrate larger then 115200, it will be changed to 115200 and use tty_encode_baud_rate() to encode into tty Signed-off-by: Peter Hung Signed-off-by: Johan Hovold

USB: f81232: implement port enable/disable method

2015-03-27T16:29:27+00:00

We put FCR/IER initial step to f81232_port_enable()/f81232_port_disable(). When port is open, it set MSR interrupt on. Otherwise set it off. Signed-off-by: Peter Hung Signed-off-by: Johan Hovold

USB: f81232: implement MCR/MSR function

2015-03-27T16:29:26+00:00

This patch implement relative MCR/MSR function, such like tiocmget()/tiocmset()/dtr_rts()/carrier_raised() original f81232_carrier_raised() compared with wrong value UART_DCD. It's should compared with UART_MSR_DCD. Signed-off-by: Peter Hung Signed-off-by: Johan Hovold

USB: f81232: implement read IIR/MSR with endpoint

2015-03-27T16:29:26+00:00

The interrupt endpoint will report current IIR. If we got IIR with MSR changed , We will do read MSR with interrupt_work worker to do f81232_read_msr() function. Signed-off-by: Peter Hung Signed-off-by: Johan Hovold
