KT Liao a04f144059 Input: elan_i2c - ignore signals when finishing updating firmware
Use wait_for_completion_timeout() instead of
wait_for_completion_interruptible_timeout() to avoid stray signals ruining
firmware update. Our timeout is only 300 msec so we are fine simply letting
it expire in case device misbehaves.

KT Liao 4b3c7dbbff Input: elan_i2c - clear INT before resetting controller
Some old touchpad FWs need to have interrupt cleared before issuing reset
command after updating firmware. We clear interrupt by attempting to read
full report from the controller, and discarding any data read.

Martin Kepplinger aa3d4409b6 Input: edt-ft5x06 - increase allowed data range for threshold parameter
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.

Merge tag 'hwparam-20170420' of 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"

Benjamin Valentin 44bc722593 Input: xpad - sync supported devices with xboxdrv
The userspace xboxdrv driver [0] contains some USB IDs unknown to the
kernel driver. I have created a simple script [1] to extract the missing
devices and add them to xpad.

A quick google search confirmed that all the new devices called
Fightstick/pad are Arcade-type devices [2] where the
MAP_TRIGGERS_TO_BUTTONS option should apply.

There are some similar devices in the existing device table where this
flag is not set, but I did refrain from changing those.

 There's lots of new drivers added this time around, new firmware drivers

 have the hardware for these drivers, and then you will be happy :)

Linus Torvalds 2bd8040174 This is the bulk of GPIO changes for the v4.12 kernel cycle:
Core changes
 
 - Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
   This was a much discussed change. 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.
 
 Driver improvements
 
 - A whole slew of drivers have their spinlocks chaned to raw spinlocks
   as they provide irqchips, and thus we are progressing on realtime
   compliance.
 
 - Use devm_irq_alloc_descs() in a slew of drivers, getting managed
   resources.
 
 - Support for the embedded PWM controller inside the MVEBU driver.
 
 - Debounce, open source and open drain support for the Aspeed driver.
 
 - Misc smaller fixes like spelling and syntax and whatnot.

2017-04-21 09:13:43 -07:00
David Howells f6b12d0434 Annotate hardware config module parameters in drivers/input/
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 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.

Cameron Gutman 81093c9848 Input: xpad - support some quirky Xbox One pads
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)
