2016-02-06tty: serial: 8250: Fix indentation warningsAnton Wuerfel1-2/+2
Checkpatch complains about incorrect indentation of switch/case statements. This patch fixes the corresponding warnings. Additionally some indentation is changed to match the correct format specified in the Linux Kernel Coding Style.

2016-02-06tty: serial: 8250: Correct conversion specifiersAnton Wuerfel1-2/+2
This patch fixes compiler warnings about wrong conversion specifiers used in a debug output in 8250_pnp.c. The precise warning is: drivers/tty/serial/8250/8250_pnp.c: In function ‘serial_pnp_probe’: include/linux/dynamic_debug.h:64:16: warning: format ‘%x’ expects argument of [...] drivers/tty/serial/8250/8250_pnp.c:467:2: note: in expansion of macro ‘dev_dbg’ dev_dbg(&dev->dev, ^ include/linux/dynamic_debug.h:64:16: warning: format ‘%lx’ expects argument of [...] drivers/tty/serial/8250/8250_pnp.c:467:2: note: in expansion of macro ‘dev_dbg’ dev_dbg(&dev->dev, ^ Those warnings never got triggered, because the command was nested in an #ifdef, which is removed by a patch of this series.

2016-02-06tty: serial: 8250: Remove SERIAL_DEBUG_PNP macroPhillip Raffeck1-5/+5
This patch removes the macro SERIAL_DEBUG_PNP, which is used to enable debugging at compile time. As SERIAL_DEBUG_PNP is an orphan, the corresponding #ifdef is removed. To keep the ability to enable debugging at compile time, the call to printk(KERN_DEBUG ...) is replaced by a corresponding call to dev_dbg(), which is configurable via CONFIG_DYNAMIC_DEBUG.

2015-08-14serial: 8250: bind to ALi Fast Infrared Controller (ALI5123)Maciej S. Szmigiero1-0/+6
This way this device can be used with irtty-sir - at least on Toshiba Satellite A20-S103 it is not configured by default and needs PNP activation before it starts to respond on I/O ports. This device has actually its own driver (ali-ircc), but this driver seems to be non-functional for a very long time (see http://permalink.gmane.org/gmane.linux.irda.general/484 http://permalink.gmane.org/gmane.network.protocols.obex.openobex.user/943 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=535070 ).

2015-02-02serial: 8250_pnp: Enable PNP_CONSOLE for console portsPeter Hurley1-1/+7
When the kernel command line parameter, no_console_suspend, is used, the console should continue to output console messages during and after system suspend. For a serial console, the serial core ensures that the device is not shutdown when no_console_suspend is specified. However, the default operation of the pnp bus will disable and suspend the device and no further output occurs. When registering the 8250 port, if the serial device is a console set the PNP_CONSOLE capability, which prevents device power-off if consoles are not suspending.

2014-01-07tty: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2013-04-08Revert "tty/8250_pnp: serial port detection regression since v3.7"Sean Young1-7/+5
This reverts commit 77e372a3d82e5e4878ce1962207edd766773cc76. Checking for disabled resources board breaks detection pnp on another board "AMI UEFI implementation (Version: 0406 Release Date: 06/06/2012)". I'm working with the reporter of the original bug to write and test a better fix. https://bugzilla.redhat.com/show_bug.cgi?id=928246 Signed-off-by: Sean Young <sean@mess.org> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-03-12tty/8250_pnp: serial port detection regression since v3.7Sean Young1-5/+7
The InsydeH2O BIOS (version dated 09/12/2011) has the following in its pnp resouces for its serial ports: $ cat /sys/bus/pnp/devices/00:0b/resources state = active io disabled irq disabled We do not check if the resources are disabled, and create a bogus ttyS* device. Since commit 835d844d1a28e (8250_pnp: do pnp probe before legacy probe) we get a bogus ttyS0, which prevents the legacy probe from detecting it. Note, the BIOS can also be upgraded, fixing this problem, but for people who can't do that, this fix is needed.

2012-09-268250: blacklist Winbond CIR portSean Young1-5/+15
The legacy serial driver will detect the Winbond CIR device as a serial port, since it looks exactly like a serial port unless you know what it is from the PNP ID. Here we track this port as a special PORT_8250_CIR type, preventing the legacy serial driver from probing it.

2012-09-268250_pnp: do pnp probe before legacy probeSean Young1-8/+3
We first probe the legacy serial ports and then check pnp. If there is a non-standard configuration then this might not work, also this change is needed so we can blacklist Winbond CIR based on PNP ID. For this to work the 8250_pnp driver must be merged into the 8250 module.

2012-01-24serial: group all the 8250 related code togetherPaul Gortmaker1-0/+524
The drivers/tty/serial dir is already getting rather busy. Relocate the 8250 related drivers to their own subdir to reduce the clutter. Note that sunsu.c is not included in this move -- it is 8250-like hardware, but it does not use any of the existing infrastructure -- and does not depend on SERIAL_8250.
