2011-06-07Basic support for Moschip 9900 family I/O chipsNicos Gollan1-16/+50
Add I/O based support for serial and parallel ports of the following chips: Vendor: Moschip (0x9710) Parts (device IDs) * 9900 (0x9900) * 9904 (0x9904 * 9901 (0x9912, also sold as 9912) * 9922 (0x9922) On all chips but the 9900, a single port is provided per PCI subdevice (subvendor-ID 0xA000, subdevice-IDs 0x1000 for serial, 0x2000 for parallel with proper class codes). In cascading configurations, the 9900 provides two devices per subdevice, with subvendor-ID 0xA000 and subdevice-IDs 0x30ps where p is the number of parallel ports and s the number of serial ports. Basic testing was only done on the serial part of a 9912 to the point where it can be used for a serial kernel console, and advanced features are completely untested. It is possible to reduce functionality of the chips by adding a configuration EEPROM, and the datasheet [1] is inconsistent w.r.t subdevices in the 4s+2s1p and 2s1p+4s configurations. The subdevice-ID 0x3012 should likely read 0x3011 with a serial port in function 3, which would be consistent with the BAR layouts. For now, the drivers ignore subdevices with ID 0x1000 and no class code. The parallel ports are integrated in parport_serial even for purely parallel parts to reduce the footprint of the patch.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+1
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2009-04-03parport: netmos 9845 & 9855 1P4S fixesPhilippe De Muyter1-5/+25
netmos serial/parallel adapters come in different flavour differing only by the number of parallel and serial ports, which are encoded in the subdevice ID. Last fix of Christian Pellegrin for 9855 2P2S broke support for 9855 1P4S, and works only by side-effect for the first parallel port of a 2P2S, as this first parallel port is found by reading the second addr entry of (struct parport_pc_pci) cards[netmos_9855], which is not initialized, and hence has value 0, which happens to be the BAR of the first parallel port. netmos_9xx5_combo entry in (struct parport_pc_pci) cards[], which is used for a 9845 1P4S must also be fixed for the parallel port support when there are 4 serial ports because this entry currently gives 2 as BAR index for the parallel port. Actually, in this case, BAR 2 is the 3rd serial port while the parallel port is at BAR 4. I fixed 9845 1P4S and 9855 1P4S support, while preserving 9855 2P2S support, - by creating a netmos_9855_2p entry and using it for 9855 boards with 2 parallel ports : 9855 2P2S and 9855 2P0S boards, - and by allowing netmos_parallel_init to change not only the number of parallel ports (0 or 1), but making it also change the BAR index of the parallel port when the serial ports are before the parallel port. PS: the netmos_9855_2p entry in (struct pciserial_board) pci_parport_serial_boards[] is needed because netmos_parallel_init has no clean way to replace FL_BASE2 by FL_BASE4 in the description of the serial ports in function of the number of parallel ports on the card.

This patch simply adds the check of the array range.

Fix wrong netmos 9855 serial port configuration. On loading only one serial port was present and it wasn't working. After looking in the data sheet I realized that the base address was wrong.

2007-05-08parport->dev driver model supportDavid Brownell1-1/+1
Currently a parport_driver can't get a handle on the device node for the underlying parport (PNPACPI, PCI, etc). That prevents correct placement of sysfs child nodes, which can affect things like power management. This patch adds a field to "struct parport" pointing to that device node, and updates non-legacy port drivers to initialize that device pointer. That field replaces the analagous PCI-only support in parport_pc.

2006-03-20[SERIAL] Merge avlab serial board entries in parport_serialRussell King1-57/+18
As can be seen from this patch, the avlab_*_[68]50 table entries are identical to the plain avlab_* entries in every respect. Hence, there is no need to list them separately in the pciserial_board nor parport_pc_pci card tables - they can re-use the plain avlab_* entries.

2006-03-06[SERIAL] Fix two bugs in parport_serialRussell King1-7/+4
Steinar H. Gunderson reported: - For some reason, it detects the 9845 as a 9735 -- it appears this is simply related to the ordering in parport_serial_pci_tbl[]. If we move the 9845 up above the 9735, it prints out 9710:9845, but no change in behaviour. (We didn't find out why this was the case; we left it alone since it didn't affect our problem.) - The card has no parallel port (at least no physical ones), yet it reports (via its subsystem ID of 0x0014) one parallel port and four serial ports. The probe for the parallel port fails, and the driver just aborts. Thus, it doesn't find the serial ports. Fix the debugging code to use dev_dbg, but don't bother displaying the PCI ID of the detected board (that's accessible via other means.) Also, arrange for parport_register() to return 0 even if it finds no ports. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-06-23[PATCH] parport: NetMos nm9855 fixMartin Schitter1-1/+4
kernel 2.6.12-rc2 adopted some code by Bjorn Helgaas supporting NetMos combo controller cards. this implementation doesn't work for nm9855 based cards! there are two reasons: a) the module 'parport_pc' doesn't want to give the resonsibility for the netmos_9855 to 'parport_serial' and can not handle the serial lines -- trivial to fix... http://lists.infradead.org/pipermail/linux-parport/2005-February/000250.html http://lkml.org/lkml/2005/3/24/199 b) the support for the nm9855 in 'parport_serial' still doesn't work because of wrong assumptions about the relevant BARs port address layout for this chip: 0000:00:09.0 Communication controller: NetMos Technology PCI 9855 Multi-I/O Controller (rev 01) (= 9710:9855) Subsystem: LSI Logic / Symbios Logic 1P4S (= 1000:0014) Flags: medium devsel, IRQ 177 I/O ports at a800 [size=8] (= parport) I/O ports at a400 [size=8] I/O ports at a000 [size=8] (= serial) I/O ports at 9800 [size=8] (= serial) I/O ports at 9400 [size=8] (= serial) I/O ports at 9000 [size=16] (= serial) the following patch will fix the problem.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
