cxl: Add base builtin support

2014-10-08T09:15:56+00:00

This adds the base cxl support that cannot be built as a module. Specifically
it adds the cxl callbacks that are called from the core powerpc mm code which
must always exist irrespective of if the cxl module is loaded or not. This is
similar to how cell works with CONFIG_SPU_BASE.

This adds a cxl_slbia() call (similar to spu_flush_all_slbs()) which checks if
the cxl module is loaded and in use, returning immediately if it is not. If it
is in use it calls into the cxl SLB invalidation code.

misc: atmel_pwm: remove obsolete driver

2014-07-09T13:14:35+00:00

The misc/atmel_pwm is not used by any mainlined boards and has been replaced by
the pwm-driver using the generic PWM framework.

mfd: vexpress: Define the device as MFD cells

2014-05-15T16:02:19+00:00

This patch - finally, after over 6 months! :-( - addresses
Samuel's request to split the vexpress-sysreg driver into
smaller portions and define the device in a form of MFD
cells:

* LEDs code has been completely removed and replaced with
  "gpio-leds" nodes in the tree (referencing dedicated
  GPIO subnodes in sysreg - bindings documentation updated);
  this also better fits the reality as some variants of the
  motherboard don't have all the LEDs populated

* syscfg bridge code has been extracted into a separate
  driver (placed in drivers/misc for no better place)

* all the ID & MISC registers are defined as sysconf
  making them available for other drivers should they need
  to use them (and also to the user via /sys/kernel/debug/regmap
  which can be helpful in platform debugging)

staging: echo: move to drivers/misc/

2014-02-28T22:08:42+00:00

The code is clean, there are users of it, so it doesn't belong in
staging anymore, move it to drivers/misc/.

Merge tag 'pwm/for-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

2013-11-16T20:21:40+00:00

Pull pwm changes from Thierry Reding:
 "Mostly bug fixes and clean up.  There is a new driver, which is
  actually moving a custom PWM driver from drivers/misc.

  The majority of the patches are enhancements to the device tree
  support in the pwm-backlight driver.  Backlights can now additionally
  be powered using a regulator and enabled using a GPIO in addition to
  just the PWM input"

pwm: add ep93xx PWM support

2013-10-17T14:07:19+00:00

Remove the non-standard EP93xx PWM driver in drivers/misc and add
a new driver for the PWM controllers on the EP93xx platform based
on the PWM framework.

These PWM controllers each support 1 PWM channel with programmable
duty cycle, frequency, and polarity inversion.

misc: generic on-chip SRAM allocation driver

2013-04-30T01:28:13+00:00

This driver requests and remaps a memory region as configured in the
device tree.  It serves memory from this region via the genalloc API.  It
optionally enables the SRAM clock.

Other drivers can retrieve the genalloc pool from a phandle pointing to
this drivers' device node in the device tree.

The allocation granularity is hard-coded to 32 bytes for now, to make the
SRAM driver useful for the 6502 remoteproc driver.  There is overhead for
bigger SRAMs, where only a much coarser allocation granularity is needed:
At 32 bytes minimum allocation size, a 256 KiB SRAM needs a 1 KiB bitmap
to track allocations.

dummy-irq: introduce a dummy IRQ handler driver

2013-03-25T20:22:32+00:00

This module accepts a single 'irq' parameter, which it should register for.

Its sole purpose is to help with debugging of IRQ sharing problems, by
force-enabling IRQ that would otherwise be disabled.
