• 11165223e   mfd: htc-i2cpld: Make it explicitly non-modular ... Browse Code »

  The Kconfig for this option is currently:

  config HTC_I2CPLD
  bool "HTC I2C PLD chip support"

  ...meaning that it currently is not being built as a module by anyone.
  Lets remove the modular code that is essentially orphaned, so that
  when reading the driver there is no doubt it is builtin-only.

  Since module_init translates to device_initcall in the non-modular
  case, the init ordering remains unchanged with this commit.

  We also delete the MODULE_LICENSE tag etc. since all that information
  is already contained at the top of the file in the comments.

• a86854d0c   treewide: devm_kzalloc() -> devm_kcalloc() ... Browse Code »

  The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
  This patch replaces cases of:

  devm_kzalloc(handle, a * b, gfp)

  with:
  devm_kcalloc(handle, a * b, gfp)

  as well as handling cases of:

  devm_kzalloc(handle, a * b * c, gfp)

  with:

  devm_kzalloc(handle, array3_size(a, b, c), gfp)

  as it's slightly less ugly than:

  devm_kcalloc(handle, array_size(a, b), c, gfp)

  This does, however, attempt to ignore constant size factors like:

  devm_kzalloc(handle, 4 * 1024, gfp)

  though any constants defined via macros get caught up in the conversion.

  Any factors with a sizeof() of "unsigned char", "char", and "u8" were
  dropped, since they're redundant.

  Some manual whitespace fixes were needed in this patch, as Coccinelle
  really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

  The Coccinelle script used for this was:

• 58383c784   gpio: change member .dev to .parent ... Browse Code »

  The name .dev in a struct is normally reserved for a struct device
  that is let us say a superclass to the thing described by the struct.
  struct gpio_chip stands out by confusingly using a struct device *dev
  to point to the parent device (such as a platform_device) that
  represents the hardware. As we want to give gpio_chip:s real devices,
  this is not working. We need to rename this member to parent.

  This was done by two coccinelle scripts, I guess it is possible to
  combine them into one, but I don't know such stuff. They look like
  this:

  @@
  struct gpio_chip *var;
  @@
  -var->dev
  +var->parent

  and:

  @@
  struct gpio_chip var;
  @@
  -var.dev
  +var.parent

  and:

  @@
  struct bgpio_chip *var;
  @@
  -var->gc.dev
  +var->gc.parent

  Plus a few instances of bgpio that I couldn't figure out how
  to teach Coccinelle to rewrite.

  This patch hits all over the place, but I *strongly* prefer this
  solution to any piecemal approaches that just exercise patch
  mechanics all over the place. It mainly hits drivers/gpio and
  drivers/pinctrl which is my own backyard anyway.

• 9bd09f345   mfd: Kill off set_irq_flags usage ... Browse Code »

  set_irq_flags is ARM specific with custom flags which have genirq
  equivalents. Convert drivers to use the genirq interfaces directly, so we
  can kill off set_irq_flags. The translation of flags is as follows:

  IRQF_VALID -> !IRQ_NOREQUEST
  IRQF_PROBE -> !IRQ_NOPROBE
  IRQF_NOAUTOEN -> IRQ_NOAUTOEN

  For IRQs managed by an irqdomain, the irqdomain core code handles clearing
  and setting IRQ_NOREQUEST already, so there is no need to do this in
  .map() functions and we can simply remove the set_irq_flags calls. Some
  users also modify IRQ_NOPROBE and this has been maintained although it
  is not clear that is really needed. There appears to be a great deal of
  blind copy and paste of this code.

  Pull GPIO changes from Linus Walleij:
  "This is the bulk of GPIO changes for the v3.18 development cycle:

  - Increase the default ARCH_NR_GPIO from 256 to 512. This was done
  to avoid having a custom header for the x86
  architecture - GPIO is custom and complicated enough as it is
  already! We want to move to a radix to store the descriptors going
  forward, and finally get rid of this fixed array size altogether.

  - Endgame patching of the gpio_remove() semantics initiated by
  Abdoulaye Berthe. It is not accepted by the system that the
  removal of a GPIO chip fails during eg reboot or shutdown, and
  therefore the return value has now painfully been refactored away.
  For special cases like GPIO expanders on a hot-pluggable bus like
  USB, we may later add some gpiochip_try_remove() call, but for the
  cases we have now, return values are moot.

  - Some incremental refactoring of the gpiolib core and ACPI GPIO
  library for more descriptor usage.

  - Refactor the chained IRQ handler set-up method to handle also
  threaded, nested interrupts and set up the parent IRQ correctly.
  Switch STMPE and TC3589x drivers to use this registration method.

  - Add a .irq_not_threaded flag to the struct gpio_chip, so that also
  GPIO expanders that block but are still not using threaded IRQ
  handlers.

  - New drivers for the ARM64 X-Gene SoC GPIO controller.

  - The syscon GPIO driver has been improved to handle the "DSP GPIO"
  found on the TI Keystone 2 SoC:s.

  - ADNP driver switched to use gpiolib irqchip helpers.

  - Refactor the DWAPB driver to support being instantiated from and
  MFD cell (platform device).

  - Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP,

  Checking the result of container_of() against NULL will always result to
  false. Using the offset of member 'chip_out' to find the start of 'struct
  htcpld_chip' will result in an offset error when .get_chip() is attempting
  to obtain 'htcpld-in'. Instead, we'll use the correct member based on a
  previously the set chip label.

  Remove the pointless irq_desc check in set_type. This function is
  called with that irq descriptor locked. Also remove the write back of
  the flow type as the core code does this already when the return value
  is 0.

  Also store the flow type in the chip data structure, so there is no
  need to fiddle in the irq descriptor.

• 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

  …it slab.h inclusion from percpu.h

  percpu.h is included by sched.h and module.h and thus ends up being
  included when building most .c files. percpu.h includes slab.h which
  in turn includes gfp.h making everything defined by the two files
  universally available and complicating inclusion dependencies.

  percpu.h -> slab.h dependency is about to be removed. Prepare for
  this change by updating users of gfp and slab facilities include those
  headers directly instead of assuming availability. As this conversion
  needs to touch large number of source files, the following script is
  used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

  The script does the followings.

  * Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there. ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

  * When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding. It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

  * If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

  The conversion was done in the following steps.

  1. The initial automatic conversion of all .c files updated slightly
  over 4000 files, deleting around 700 includes and adding ~480 gfp.h
  and ~3000 slab.h inclusions. The script emitted errors for ~400
  files.

  2. Each error was manually checked. Some didn't need the inclusion,
  some needed manual addition while adding it to implementation .h or
  embedding .c file was more appropriate for others. This step added
  inclusions to around 150 files.

  3. The script was run again and the output was compared to the edits
  from #2 to make sure no file was left behind.

  4. Several build tests were done and a couple of problems were fixed.
  e.g. lib/decompress_*.c used malloc/free() wrappers around slab
  APIs requiring slab.h to be added manually.

  5. The script was run on all .h files but without automatically
  editing them as sprinkling gfp.h and slab.h inclusions around .h
  files could easily lead to inclusion dependency hell. Most gfp.h
  inclusion directives were ignored as stuff from gfp.h was usually
  wildly available and often used in preprocessor macros. Each
  slab.h inclusion directive was examined and added manually as
  necessary.

  6. percpu.h was updated not to include slab.h.

  7. Build test were done on the following configurations and failures
  were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
  distributed build env didn't work with gcov compiles) and a few
  more options had to be turned off depending on archs to make things
  build (like ipr on powerpc/64 which failed due to missing writeq).

  * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
  * powerpc and powerpc64 SMP allmodconfig
  * sparc and sparc64 SMP allmodconfig
  * ia64 SMP allmodconfig
  * s390 SMP allmodconfig
  * alpha SMP allmodconfig
  * um on x86_64 SMP allmodconfig

  8. percpu.h modifications were reverted so that it could be applied as
  a separate patch and serve as bisection point.

  Given the fact that I had only a couple of failures from tests on step
  6, I'm fairly confident about the coverage of this conversion patch.
  If there is a breakage, it's likely to be something in one of the arch
  headers which should be easily discoverable easily on most builds of
  the specific arch.

• 6048a3dd2   mfd: Add HTCPLD driver ... Browse Code »

  This change introduces a driver for the HTC PLD chip found
  on some smartphones, such as the HTC Wizard and HTC Herald.
  It works through the I2C bus and acts as a GPIO extender.
  Specifically:

  * it can have several sub-devices, each with its own I2C
  address
  * Each sub-device provides 8 output and 8 input pins
  * The chip attaches to one GPIO to signal when any of the
  input GPIOs change -- at which point all chips must be
  scanned for changes

  This driver implements the GPIOs throught the kernel's
  GPIO and IRQ framework. This allows any GPIO-servicing
  drivers to operate on htcpld pins, such as the gpio-keys
  and gpio-leds drivers.
