2015-12-13tty: core: Add driver name to invalid device registration messagePeter Hurley
Include the driver name in the tty_register_device_attr() error message for invalid index. Note that tty_err() cannot be used here because there is no tty; use pr_err(). Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-12-13tty: Convert SAK messages to tty_notice()Peter Hurley
Use tty_notice() for unified message format from the tty core. Fix each message to accurately reflect the cause of each termination. Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-12-13tty: Define tty_*() printk macrosPeter Hurley
Since not all ttys are devices (eg., SysV ptys), dev_*() printk macros cannot be used. Define tty_*() printk macros that output in similar format to dev_*() macros (ie., <driver> <tty>: .....). Transform the most-trivial printk( LEVEL ...) usage to tty_*() usage. NB: The function name has been eliminated from messages with unique context, or prefixed to the format when given.

2015-12-13tty: Improve tty_debug() macroPeter Hurley
Incorporate suggestions for tty core debug macro improvements - printk(KERN_DEBUG) => pr_debug() - ##args => ##__VA_ARGS__ - remove do {} while() - output tty_name() first cc: Joe Perches <joe@perches.com> Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-12-13tty: amba-pl011: prepare REG_* register indexesRussell King
Prepare for REG_* register accessors. This change involves introducing pl011_reg_to_offset() to convert REG_* to the hardware register offset, and converting all call sites to use REG_* names. We need to fix up locations where we check for equivalence of register offsets as well. Much of this change was made via these sed expressions: s/ST_UART01[1x]\(_[^_]*\|_LCRH_[TR]X\)\>/REG_ST\1/ s/UART01[1x]_\(DR\|RSR\|ECR\|FR\|ILPR\|[IF]BRD\|LCRH\|CR\|IFLS\|IMSC\|RIS\|MIS\|ICR\|DMACR\)\>/REG_\1/g Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Reviewed-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2015-12-13serial: support 16-bit register interface for consoleMasahiro Yamada
Currently, 8-bit (MMIO) and 32-bit (MMIO32) register interfaces are supported for the 8250 console, but the 16-bit (MMIO16) is not. The 8250 UART device on my board is connected to a 16-bit bus and my main motivation is to use earlycon with it.

2015-12-13serial: 8250_early: confirm empty transmitter after sending charactersMasahiro Yamada
The current code waits until the transmitter becomes empty, before sending each character, and after finishing the whole string. This seems a bit redundant. It can be more efficient by checking the transmitter only after sending each character. This should be safe because the transmitter is already empty at the first entry of serial_putc().

2015-12-13drivers/tty/serial: make 8250/8250_mtk.c explicitly non-modularPaul Gortmaker
The Kconfig currently controlling compilation of this code is: drivers/tty/serial/8250/Kconfig:config SERIAL_8250_MT6577 drivers/tty/serial/8250/Kconfig: bool "Mediatek serial port support" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
