2013-12-20ARM/serial: at91: switch atmel serial to use gpiolibLinus Walleij1-18/+31
This passes the errata fix using a GPIO to control the RTS pin on one of the AT91 chips to use gpiolib instead of the AT91-specific interfaces. Also remove the reliance on compile-time #defines and the cpu_* check and rely on the platform passing down the proper GPIO pin through platform data. This is a prerequisite for getting rid of the local GPIO implementation in the AT91 platform and move toward multiplatform. The patch also adds device tree support for getting the RTS GPIO pin from the device tree on DT boot paths.

2013-12-17serial: amba-pl011: use port lock to guard control register accessJon Medhurst1-0/+6
When the pl011 is being used for a console, pl011_console_write forces the control register (CR) to enable the UART for transmission and then restores this to the original value afterwards. It does this while holding the port lock. Unfortunately, when the uart is started or shutdown - say in response to userland using the serial device for a terminal - then this updates the control register without any locking. This means we can have pl011_console_write Save CR pl011_startup Initialise CR, e.g. enable receive pl011_console_write Restore old CR with receive not enabled this result is a serial port which doesn't respond to any input. A similar race in reverse could happen when the device is shutdown. We can fix these problems by taking the port lock when updating CR.

2013-12-16serial: 8250_dw: Fix LCR workaround regressionJames Hogan1-2/+4
Commit c49436b657d0 (serial: 8250_dw: Improve unwritable LCR workaround) caused a regression. It added a check that the LCR was written properly to detect and workaround the busy quirk, but the behaviour of bit 5 (UART_LCR_SPAR) differs between IP versions 3.00a and 3.14c per the docs. On older versions this caused the check to fail and it would repeatedly force idle and rewrite the LCR register, causing delays and preventing any input from serial being received. This is fixed by masking out UART_LCR_SPAR before making the comparison.

2013-12-14serial: sh-sci: Don't enable/disable port from within break timerLaurent Pinchart1-4/+8
The break timer accesses hardware registers and thus requires the port to be enabled. It currently ensures this by enabling the port at the beginning of the timer handler, and disabling it at the end. However, the enable/disable operations call the runtime PM sync functions, which are not allowed in atomic context. The current situation is thus broken. This change relies on non-atomic code to enable/disable the port. The break timer will only be started from the IRQ handler, which already runs with the port enabled. We just need to ensure that the port won't be disabled with the timer running, and that's easily done by just cancelling the timer in the port disable function.

2013-12-08serial: samsung: move clock deactivation below uart registrationHeiko Stübner1-1/+7
Commit 60e93575476f (serial: samsung: enable clock before clearing pending interrupts during init) added handling of the controller clock during init. On most systems this clock is also one of the baud_clock sources and possibly used by the earlycon and thus already enabled by the bootloader. Therefore a gap exists between s3c24xx_serial_init_port disabling the clock and an attached console reenabling it, making the transition from earlycon to regular console possibly hang the system - as seen on my S3C2442 based Freerunner today. Therefore move the disabling of the clock from s3c24xx_serial_init_port below the uart port registration, effectively creating an overlap and keeping the clock running non-stop if the console wants to grab this port.

The uart_set_options() code unconditionally initalizes the spinlock on the port. This can cause a deadlock in some situations. One instance that exposed the problem, was when writing to /sys/module/kgdboc/parameters/kgdboc to use ttyS0 when the console is already running on ttyS0. If the spinlock is re-initialized while the lock is held due to output to the console, there is a deadlock. Assume the spinlock is initialized if the port is a console.

2013-10-29serial: omap: improve RS-485 performancePhilippe Proulx1-12/+38
If RS-485 is enabled, make the OMAP UART fire THR interrupts when both TX FIFO and TX shift register are empty instead of polling the equivalent status bit. This removes the burst of interrupt requests seen at every end of transmission. Also: the comment said that the TX FIFO trigger level was set at 16 characters when it's 32 in reality.
