parport: parport_serial: Add Brainboxes device IDs and geometry

2024-01-20T10:50:11+00:00

commit 6aa1fc5a8085bbc01687aa708dcf2dbe637a5ee3 upstream. Add device IDs for the Brainboxes UC-203, UC-257, UC-414, UC-475, IS-300/IS-500 and PX-263/PX-295 and define the relevant "geometry" for the cards. This patch requires part 1 of this series.

parport_pc: Avoid FIFO port location truncation

2022-11-09T14:40:32+00:00

Match the data type of a temporary holding a reference to the FIFO port with the type of the original reference coming from `struct parport', avoiding data truncation with LP64 ports such as SPARC64 that refer to PCI port I/O locations via their corresponding MMIO addresses and will therefore have non-zero bits in the high 32-bit part of the reference. And in any case it is cleaner to have the data types matching here. Signed-off-by: Maciej W.

parport: add support for Netmos device 9900

2022-09-01T15:46:06+00:00

The Netmos parallel port 9901 was already supported but the device 9900 was not. This patch adds the required settings for it and was successfully tested with the Netmos device 9900.

parport_pc: Also enable driver for PCI systems

2022-03-18T13:01:41+00:00

Nowadays PC-style parallel ports come in the form of PCI and PCIe option cards and there are some combined parallel/serial option cards as well that we handle in the parport subsystem. There is nothing in particular that would prevent them from being used in any system equipped with PCI or PCIe connectivity, except that we do not permit the PARPORT_PC config option to be selected for platforms for which ARCH_MIGHT_HAVE_PC_PARPORT has not been set for. The only PCI platforms that actually can't make use of PC-style parallel port hardware are those newer PCIe systems that have no support for I/O cycles in the host bridge, required by such parallel ports. Notably, this includes the s390 arch, which has port I/O accessors that cause compilation warnings (promoted to errors with `-Werror'), and there are other cases such as the POWER9 PHB4 device, though this one has variable port I/O accessors that depend on the particular system. Also it is not clear whether the serial port side of devices enabled by PARPORT_SERIAL uses port I/O or MMIO. Finally Super I/O solutions are always either ISA or platform devices. Make the PARPORT_PC option selectable also for PCI systems then, except for the s390 arch, however limit the availability of PARPORT_PC_SUPERIO to platforms that enable ARCH_MIGHT_HAVE_PC_PARPORT. Update platforms accordingly for the required header. Acked-by: Sudip Mukherjee Signed-off-by: Maciej W.

parisc: Make struct parisc_driver::remove() return void

2021-08-30T08:18:25+00:00

The caller of this function (parisc_driver_remove() in arch/parisc/kernel/drivers.c) ignores the return value, so better don't return any value at all to not wake wrong expectations in driver authors. The only function that could return a non-zero value before was ipmi_parisc_remove() which returns the return value of ipmi_si_remove_by_dev(). Make this function return void, too, as for all other callers the value is ignored, too. Also fold in a small checkpatch fix for: WARNING: Unnecessary space before function pointer arguments + void (*remove) (struct parisc_device *dev); Acked-by: Dmitry Torokhov (for drivers/input) Signed-off-by: Uwe Kleine-König Acked-by: Sudip Mukherjee Acked-by: Jiri Slaby Signed-off-by: Helge Deller

parport: remove non-zero check on count

2021-08-27T14:18:42+00:00

The check for count appears to be incorrect since a non-zero count check occurs a couple of statements earlier. Currently the check is always false and the dev->port->irq != PARPORT_IRQ_NONE part of the check is never tested and the if statement is dead-code. Fix this by removing the check on count. Note that this code is pre-git history, so I can't find a sha for it.
