serial: xilinx: Use platform_get_irq to get irq description structure

2015-04-28T12:26:21Z

For systems with CONFIG_SERIAL_OF_PLATFORM=y and device_type = "serial"; property in DT of_serial.c driver maps and unmaps IRQ (because driver probe fails). Then a driver is called but irq mapping is not created that's why driver is failing again in again on request_irq(). Based on this use platform_get_irq() instead of platform_get_resource() which is doing irq_desc allocation and driver itself can request IRQ. Fix both xilinx serial drivers in the tree.

tty: constify of_device_id array

2015-03-26T21:49:10Z

of_device_id is always used as const. (See driver.of_match_table and open firmware functions) Signed-off-by: Fabian Frederick Acked-by: Peter Korsgaard Acked-by: Timur Tabi Acked-by: Patrice Chotard Signed-off-by: Greg Kroah-Hartman

tty: serial: uartlite: Remove .owner field for driver

2014-09-08T23:09:13Z

There is no need to init .owner field. Based on the patch from Peter Griffin "mmc: remove .owner field for drivers using module_platform_driver" This patch removes the superflous .owner field for drivers which use the module_platform_driver API, as this is overriden in platform_driver_register anyway."

tty: serial: uartlite: Specify time for sending chars

2014-05-28T19:24:31Z

Xilinx MDM (Microblaze Debug Module) also contains uart interface via JTAG which is compatible with uartlite driver. This interface is really slow that's why timeout is setup to 1s. Make this time delay not to be cpu speed dependent. Signed-off-by: Michal Simek Acked-by: Peter Korsgaard Signed-off-by: Greg Kroah-Hartman

tty: serial: uartlite: Support uartlite on big and little endian systems

2013-02-13T16:38:45Z

Use big and little endian accessors function to reflect system configuration. Detection is done via control register in ulite_request_port. Tested on Microblaze LE, BE, PPC440 and Arm zynq. Signed-off-by: Michal Simek Acked-by: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman

TTY: switch tty_flip_buffer_push

2013-01-16T06:30:15Z

Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push. IOW we also closed all the races in drivers not using tty_port_tty_get at all yet. Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.

TTY: switch tty_insert_flip_char

2013-01-16T06:21:36Z

Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. tty_insert_flip_char is the next one to proceed. This one is used all over the code, so the patch is huge.

tty: remove use of __devexit

2012-11-21T23:27:46Z

CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed.
