2014-09-11serial: 8250: don't use slave_id of dma_slave_configAndy Shevchenko
That field has been deprecated in favour of getting the necessary information from ACPI or DT. However, we still need to deal systems that are PCI only (no ACPI to back up) like Intel Bay Trail. In order to support such systems, we explicitly bind setup() to the appropriate DMA filter function and its corresponding parameter. Then when serial8250_request_dma() doesn't find the channel via ACPI or DT, it falls back to use the given filter function.

Add support for Advantech PCM-3614I/PCM-3618I serial expansion cards Advantech makes a variety of serial port expansion cards, including the PCM-3614 and PCM-3618 (http://www.advantech.com/products/1-2JKLU5/PCM-3618/mod_5DF8DE5A-6B49-4429-BB2F-CB35FE1D168D.aspx). They have a driver available which was forked from the kernel driver ages ago and has not been maintained in quite some time, available at http://support.advantech.com.tw/Support/DownloadSRDetail_New.aspx?SR_ID=1-1W8FZ5&Doc_Source=Download Their driver added several features to aid in communications at higher baud rates, but at normal serial port speeds, the standard 8250_pci driver functions just fine. This patch adds the necessary PCI IDs to recognize this card.

2014-02-13serial: 8250_pci: unbreak last serial ports on NetMos 9865 cardsDmitry Eremin-Solenikov
Aparently 9865 uses standard BAR encoding scheme (unlike 99xx cards). Current pci_netmos_9900_setup() uses wrong BAR indices for the 9865 PCI device, function 2.

2013-03-15serial: 8250_pci: Add WCH CH352 quirk to avoid Xscale detectionWang YanQing
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.

2013-03-12Fix 4 port and add support for 8 port 'Unknown' PCI serial port cardsScott Ashcroft
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>

2012-10-24x86: ce4100: allow second UART usageMaxime Bizon
The current CE4100 and 8250_pci code have both a limitation preventing the registration and usage of CE4100's second UART. This patch changes the platform code fixing up the UART port to work on a relative UART port base address, as well as the 8250_pci code to make it register 2 UART ports for CE4100 and pass the port index down to all consumers.

2012-09-05parport_serial: Add support for the WCH353 2S/1P multi-IO cardGuainluca Anzolin
To allow parport_serial to handle the card the same PCI ids are blacklisted in 8250_pci.c using the existing software blacklist mechanism. The blacklist array is also renamed because it now covers this new use case. Since the two serial ports are auto-detected as XScale instead of 16550A clones, we also add a quirk to 8250_pci.c to skip autodetection and set the correct port type.

2012-07-128250: add support for ASIX devices with a FIFO bugAlan Cox
Information and a different patch provided by <donald@asix.com.tw>. We do it a little differently to keep the modularity and to avoid playing with RLSI. We add a new uart bug for the parity flaw and set it in the pci matches. If parity check is enabled then we drop the FIFO trigger to 1 as per the Asix reference code.
