2013-03-29serial: 8250: Make SERIAL_8250_RUNTIME_UARTS work correctlyKarthik Manamcheri1-7/+7
Consider a situation where I have an ARM based system and therefore no legacy ports. Say, I have two memory-mapped ports. I use device tree to describe the ports. What would be the config options I set so that I get only the two ports in my system? I do not want legacy ports being created automatically and I want it to be flexible enough that it creates the devices based only on the device tree. I expected setting SERIAL_8250_RUNTIME_UARTS = 0 to work because the description said, "Set this to the maximum number of serial ports you want the kernel to register at boot time." Unfortunately, even though SERIAL_8250_NR_UARTS was set to the default value of 4, I did not get any device nodes (because SERIAL_8250_RUNTIME_UARTS was 0). This is what this change is addressing. SERIAL_8250_NR_UARTS controls the maximum number of ports you can support. SERIAL_8250_RUNTIME_UARTS specifies the number of ports you want to create automatically for legacy ports at boot time. All other ports will be created when serial8250_register_port is called (and if does not exceed the total number of supported ports as specified by SERIAL_8250_NR_UARTS).

2013-03-26TTY: 8250, revert module name changeJiri Slaby2-6/+6
In 3.7 the 8250 module name was changed unintentionally from 8250 to 8250_core by commit 835d844d1a28efba81d5aca7385e24c29d3a6db2 (8250_pnp: do pnp probe before legacy probe). We then had to re-introduce the old module options to ensure the old good 8250.nr_uart & co. still work. This can be done only by a very dirty hack and we did it in f2b8dfd9e480c3db3bad0c25c590a5d11b31f4ef (serial: 8250: Keep 8250.<xxxx> module options functional after driver rename). That is so damn ugly so that I decided to revert to the old module name and deprecate the new 8250_core options present in 3.7 and 3.8 only. The deprecation will happen in the following patch. Note that this patch changes the hack above to support "8250_core.*", because we now have "8250.*" natively.

2013-03-16serial: 8250_pci: Add WCH CH352 quirk to avoid Xscale detectionWang YanQing1-0/+13
The code in 8250.c for detecting ARM/XScale UARTs says: * Try writing and reading the UART_IER_UUE bit (b6). * If it works, this is probably one of the Xscale platform's * internal UARTs. If the above passes, it then goes on to: * It's an Xscale. * We'll leave the UART_IER_UUE bit set to 1 (enabled). However, the CH352 uses the UART_IER_UUE as the LOWPOWER function, so it is readable and writable. According to the datasheet: "LOWPOWER:When the bit is 1, close the internal benchmark clock of serial port to set into low-power status. So it essentially gets mis-detected as Xscale, and gets powered down in the process. The device in question where this was seen is listed by lspci as: Serial controller: Device 4348:3253 (rev 10) (prog-if 02 [16550]) Re-using the 353 quirk which just sets flags to fixed and type to 16550 is suitable for fixing the 352 as well.

2013-03-12serial: 8250: Keep 8250.<xxxx> module options functional after driver renameJosh Boyer1-0/+29
With commit 835d844d1 (8250_pnp: do pnp probe before legacy probe), the 8250 driver was renamed to 8250_core. This means any existing usage of the 8259.<xxxx> module parameters or as a kernel command line switch is now broken, as the 8250_core driver doesn't parse options belonging to something called "8250". To solve this, we redefine the module options in a dummy function using a redefined MODULE_PARAM_PREFX when built into the kernel. In the case where we're building as a module, we provide an alias to the old 8250 name. The dummy function prevents compiler errors due to global variable redefinitions that happen as part of the module_param_ macro expansions.

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.

2013-03-12Fix 4 port and add support for 8 port 'Unknown' PCI serial port cardsScott Ashcroft1-10/+7
I've managed to find an 8 port version of the card 4 port card which was discussed here: http://marc.info/?l=linux-serial&m=120760744205314&w=2 Looking back at that thread there were two issues in the original patch. 1) The I/O ports for the UARTs are within BAR2 not BAR0. This can been seen in the original post. 2) A serial quirk isn't needed as these cards have no memory in BAR0 which makes pci_plx9050_init just return. This patch fixes the 4 port support to use BAR2, removes the bogus quirk and adds support for the 8 port card. $ lspci -vvv -n -s 00:08.0 00:08.0 0780: 10b5:9050 (rev 01) Subsystem: 10b5:1588 Control: I/O+ Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Interrupt: pin A routed to IRQ 17 Region 1: I/O ports at ff00 [size=128] Region 2: I/O ports at fe00 [size=64] Region 3: I/O ports at fd00 [size=8] Capabilities: <access denied> Kernel driver in use: serial $ dmesg | grep 0000:00:08.0: [ 0.083320] pci 0000:00:08.0: [10b5:9050] type 0 class 0x000780 [ 0.083355] pci 0000:00:08.0: reg 14: [io 0xff00-0xff7f] [ 0.083369] pci 0000:00:08.0: reg 18: [io 0xfe00-0xfe3f] [ 0.083382] pci 0000:00:08.0: reg 1c: [io 0xfd00-0xfd07] [ 0.083460] pci 0000:00:08.0: PME# supported from D0 D3hot [ 1.212867] 0000:00:08.0: ttyS4 at I/O 0xfe00 (irq = 17) is a 16550A [ 1.233073] 0000:00:08.0: ttyS5 at I/O 0xfe08 (irq = 17) is a 16550A [ 1.253270] 0000:00:08.0: ttyS6 at I/O 0xfe10 (irq = 17) is a 16550A [ 1.273468] 0000:00:08.0: ttyS7 at I/O 0xfe18 (irq = 17) is a 16550A [ 1.293666] 0000:00:08.0: ttyS8 at I/O 0xfe20 (irq = 17) is a 16550A [ 1.313863] 0000:00:08.0: ttyS9 at I/O 0xfe28 (irq = 17) is a 16550A [ 1.334061] 0000:00:08.0: ttyS10 at I/O 0xfe30 (irq = 17) is a 16550A [ 1.354258] 0000:00:08.0: ttyS11 at I/O 0xfe38 (irq = 17) is a 16550A Signed-off-by: Scott Ashcroft <scott.ashcroft@talk21.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
