* tty: max310x: Use dev_pm_opsLars-Peter Clausen2013-03-181-8/+16
| | | | | | | | | Use dev_pm_ops instead of the deprecated legacy suspend/resume for the max310x driver. Cc: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* TTY: switch tty_flip_buffer_pushJiri Slaby2013-01-151-7/+1
| | | | | | | | | | | | | | | | | | | | 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: serial: max310x: Check return code of gpiochip_removeEmil Goode2012-09-051-3/+7
| | | | | | | | | | | | | | | | | | The gpiochip_remove function may fail to remove a gpio_chip if any GPIOs are still requested. This patch informs the caller of such a senario. Sparse is warning because the function prototype has a __must_check annotation.

* serial: New serial driver MAX310XAlexander Shiyan2012-08-161-0/+1259
This driver is a replacement for a MAX3107 driver with a lot of improvements and new features. The main differences from the old version: - Using the regmap. - Using devm_XXX-related functions. - The use of threaded IRQ with IRQF_ONESHOT flag allows the driver to the hardware that supports only level IRQ. - Improved error handling of serial port, improved FIFO handling, improved hardware & software flow control. - Advanced flags allows turn on RS-485 mode (Auto direction control). - Ability to load multiple instances of drivers. - Added support for MAX3108. - GPIO support. - Driver is quite ready for adding I2C support and support other ICs with compatible registers set (MAX3109, MAX14830).
