Merge tag 'char-misc-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver updates from Greg KH:
 "Here is the bit set of char/misc drivers for 4.19-rc1

  There is a lot here, much more than normal, seems like everyone is
  writing new driver subsystems these days... Anyway, major things here
  are:

   - new FSI driver subsystem, yet-another-powerpc low-level hardware
     bus

   - gnss, finally an in-kernel GPS subsystem to try to tame all of the
     crazy out-of-tree drivers that have been floating around for years,
     combined with some really hacky userspace implementations. This is
     only for GNSS receivers, but you have to start somewhere, and this
     is great to see.

  Other than that, there are new slimbus drivers, new coresight drivers,
  new fpga drivers, and loads of DT bindings for all of these and
  existing drivers.

  All of these have been in linux-next for a while with no reported
  issues"

pinctrl: intel: Don't shadow error code of gpiochip_lock_as_irq()

2018-08-03T17:42:58+00:00

gpiochip_lock_as_irq() may return a few error codes,
do not shadow them by -EINVAL and let caller to decide.

No functional change intended.

pinctrl: cannonlake: Fix community ordering for H variant

2018-07-29T22:01:42+00:00

The driver was written based on an assumption that BIOS provides
unordered communities in ACPI DSDT. Nevertheless, it seems that
BIOS getting fixed before being provisioned to OxM:s.
So does driver.

pinctrl: intel: Do pin translation when lock IRQ

2018-07-29T21:28:44+00:00

Default GPIOLIB callbacks for request and release IRQ do not do a GPIO
to pin translation which is necessary for Intel hardware, such as Intel
Cannonlake. Absence of the translation prevents some pins to be locked
as IRQ due to direction check. Introduce own callbacks to make
translation possible to avoid above issue.

headers: separate linux/mod_devicetable.h from linux/platform_device.h

At over 4000 #includes,  is the 9th most
#included header file in the Linux kernel.  It does not need
, so drop that header and explicitly add
 to source files that need it.

   4146 #include 

After this patch, there are 225 files that use ,
for a reduction of around 3900 times that 
does not have to be read & parsed.

    225 #include 

This patch was build-tested on 20 different arch-es.

It also makes these drivers SubmitChecklist#1 compliant.

pinctrl: intel: Add Ice Lake PCH pin controller support

2018-06-29T12:51:26+00:00

This adds pinctrl/GPIO support for Intel Ice Lake PCH. The Ice Lake PCH
GPIO is based on the same version of the Intel GPIO hardware than Intel
Cannon Lake with different set of pins and ACPI ID.

pinctrl: cedarfork: Correct EAST pin ordering

2018-06-28T14:11:38+00:00

The driver missed the fact that PECI_SMB_DATA has moved from EAST
community 224 to 182 instead. Correct the pin ordering accordingly.
