2017-05-22Input: edt-ft5x06 - increase allowed data range for threshold parameterMartin Kepplinger
The datasheet and application note does not mention an allowed range for the M09_REGISTER_THRESHOLD parameter. One of our customers needs to set lower values than 20 and they seem to work just fine on EDT EP0xx0M09 with T5x06 touch. So, lacking a known lower limit, we increase the range for thresholds, and set the lower limit to 0. The documentation is updated accordingly.

2017-05-10Merge tag 'hwparam-20170420' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull hw lockdown support from David Howells: "Annotation of module parameters that configure hardware resources including ioports, iomem addresses, irq lines and dma channels. This allows a future patch to prohibit the use of such module parameters to prevent that hardware from being abused to gain access to the running kernel image as part of locking the kernel down under UEFI secure boot conditions. Annotations are made by changing: module_param(n, t, p) module_param_named(n, v, t, p) module_param_array(n, t, m, p) to: module_param_hw(n, t, hwtype, p) module_param_hw_named(n, v, t, hwtype, p) module_param_hw_array(n, t, hwtype, m, p) where the module parameter refers to a hardware setting hwtype specifies the type of the resource being configured. This can be one of: ioport Module parameter configures an I/O port iomem Module parameter configures an I/O mem address ioport_or_iomem Module parameter could be either (runtime set) irq Module parameter configures an I/O port dma Module parameter configures a DMA channel dma_addr Module parameter configures a DMA buffer address other Module parameter configures some other value Note that the hwtype is compile checked, but not currently stored (the lockdown code probably won't require it). It is, however, there for future use. A bonus is that the hwtype can also be used for grepping. The intention is for the kernel to ignore or reject attempts to set annotated module parameters if lockdown is enabled. This applies to options passed on the boot command line, passed to insmod/modprobe or direct twiddling in /sys/module/ parameter files. The module initialisation then needs to handle the parameter not being set, by (1) giving an error, (2) probing for a value or (3) using a reasonable default. What I can't do is just reject a module out of hand because it may take a hardware setting in the module parameters. Some important modules, some ipmi stuff for instance, both probe for hardware and allow hardware to be manually specified; if the driver is aborts with any error, you don't get any ipmi hardware. Further, trying to do this entirely in the module initialisation code doesn't protect against sysfs twiddling. [!] Note that in and of itself, this series of patches should have no effect on the the size of the kernel or code execution - that is left to a patch in the next series to effect. It does mark annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in an already existing field" * tag 'hwparam-20170420' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: (38 commits) Annotate hardware config module parameters in sound/pci/ Annotate hardware config module parameters in sound/oss/ Annotate hardware config module parameters in sound/isa/ Annotate hardware config module parameters in sound/drivers/ Annotate hardware config module parameters in fs/pstore/ Annotate hardware config module parameters in drivers/watchdog/ Annotate hardware config module parameters in drivers/video/ Annotate hardware config module parameters in drivers/tty/ Annotate hardware config module parameters in drivers/staging/vme/ Annotate hardware config module parameters in drivers/staging/speakup/ Annotate hardware config module parameters in drivers/staging/media/ Annotate hardware config module parameters in drivers/scsi/ Annotate hardware config module parameters in drivers/pcmcia/ Annotate hardware config module parameters in drivers/pci/hotplug/ Annotate hardware config module parameters in drivers/parport/ Annotate hardware config module parameters in drivers/net/wireless/ Annotate hardware config module parameters in drivers/net/wan/ Annotate hardware config module parameters in drivers/net/irda/ Annotate hardware config module parameters in drivers/net/hamradio/ Annotate hardware config module parameters in drivers/net/ethernet/ ...

It affects use cases where people write drivers that might or might not be using GPIO resources. I have decided that this is the lesser evil right now. - Make gpiod_count() behave consistently across different hardware descriptions. - Fix the syntax around open drain/open source to not infer active high/low semantics. New drivers: - A new single-register fixed-direction framework driver for hardware that have lines controlled by a single register that just work in one direction (out or in), including IRQ support. - Support the Fintek F71889A GPIO SuperIO controller. - Support the National NI 169445 MMIO GPIO. - Support for the X-Gene derivative of the DWC GPIO controller - Support for the Rohm BD9571MWV-M PMIC GPIO controller. - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver and replace both the Gemini and the Moxa ART custom drivers with this driver.

2017-04-20Annotate hardware config module parameters in drivers/input/David Howells
When the kernel is running in secure boot mode, we lock down the kernel to prevent userspace from modifying the running kernel image. Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image. To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is. Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters. This patch annotates drivers in drivers/input/.

The data in F12_2D_Ctrl8 corresponds to the inactive border width used by the RMI device. It is not in pixel units and should not be treated as a clip value.

2017-04-14Input: synaptics-rmi4 - use dev_driver_string when registering interruptNick Dyer
When IRQ handling was moved to rmi_driver in 3aeed5b the naming of the interrupt changed from "rmi4_i2c" to "2-0020" (or similar). This patch restores the previous behaviour and makes the interrupt easier to identify in /proc/interrupts.

ar1021_i2c also supports the ar1020 device I'm using. This is tested. They also share the same datasheet: http://ww1.microchip.com/downloads/en/DeviceDoc/40001393C.pdf So let users see that they have a compatible in front of them by adding AR1020 to the driver's description.

2017-04-14Input: ar1021_i2c - do not force raising edge IRQ triggerDmitry Torokhov
We should not be forcing edge triggered interrupt, but rather let platform decide the kind of trigger it needs to use. Also, the driver is not quite safe with regard to edge-triggered interrupts as it does not try to kick the controller after requesting/enabling IRQ.

2017-04-14Input: ar1021_i2c - fix too long name in driver's device tableDmitry Torokhov
The name field in structure i2c_device_id is 20 characters, and we expect it to be NULL-terminated, however we are trying to stuff it with 21 bytes and thus NULL-terminator is lost. This causes issues when one creates device with name "MICROCHIP_AR1021_I2C" as i2c core cuts off the last "C", and automatic module loading by alias does not work as result. The -I2C suffix in the device name is superfluous, we know what bus we are dealing with, so let's drop it. Also, no other driver uses capitals, and the manufacturer name is normally not included, except in very rare cases of incompatible name collisions.

2017-04-10Input: xpad - support some quirky Xbox One padsCameron Gutman
There are several quirky Xbox One pads that depend on initialization packets that the Microsoft pads don't require. To deal with these, I've added a mechanism for issuing device-specific initialization packets using a VID/PID-based quirks list. For the initial set of init quirks, I have added quirk handling from Valve's Steam Link xpad driver[0] and the 360Controller project[1] for macOS to enable some new pads to work properly. This should enable full functionality on the following quirky pads: 0x0e6f:0x0165 - Titanfall 2 gamepad (previously fully non-functional) 0x0f0d:0x0067 - Hori Horipad (analog sticks previously non-functional) 0x24c6:0x541a - PowerA Xbox One pad (previously fully non-functional) 0x24c6:0x542a - PowerA Xbox One pad (previously fully non-functional) 0x24c6:0x543a - PowerA Xbox One pad (previously fully non-functional) [0]: https://github.com/ValveSoftware/steamlink-sdk/blob/master/kernel/drivers/input/joystick/xpad.c [1]: https://github.com/360Controller/360Controller Signed-off-by: Cameron Gutman <aicommander@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
