pinctrl: nomadik: hide unused functions

2016-01-28T10:36:00+00:00

The nomadik pinctrl driver has two functions that are only used
for debugfs output and are otherwise unused:

drivers/pinctrl/nomadik/pinctrl-abx500.c:194:12: error: 'abx500_get_pull_updown' defined but not used
drivers/pinctrl/nomadik/pinctrl-abx500.c:471:12: error: 'abx500_get_mode' defined but not used

This makes the function definitions conditional to avoid the
harmless warnings.

pinctrl: abx500: use gpiochip data pointer

2016-01-05T13:14:51+00:00

This makes the driver use the data pointer added to the gpio_chip
to store a pointer to the state container instead of relying on
container_of().

gpio: change member .dev to .parent

2015-11-19T08:24:35+00:00

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.

pinctrl: replace trivial implementations of gpio_chip request/free

2015-10-16T20:20:21+00:00

Replace all trivial request/free callbacks that do nothing but call into
pinctrl code with the generic versions.

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.

Remove the argument.

Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

Merge tag 'pinctrl-v4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

2015-09-04T17:22:09+00:00

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.3 development
cycle.

Like with GPIO it's a lot of stuff. If my subsystems are any sign of
the overall tempo of the kernel v4.3 will be a gigantic diff.

[ It looks like 4.3 is calmer than 4.2 in most other subsystems, but
we'll see - Linus ]

Core changes:

- It is possible configure groups in debugfs.

- Consolidation of chained IRQ handler install/remove replacing all
call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a combined
call to irq_set_chained_handler_and_data(). This series was
created by Thomas Gleixner after the problem was observed by
Russell King.

- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which is
way cleaner.

- Tglx also wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs from
IRQ numbers. The goal is to get rid of the irq number from the
handlers in the IRQ flow which is nice.

Driver feature enhancements:

- Power management support for the SiRF SoC Atlas 7.

- Power down support for the Qualcomm driver.

- Intel Cherryview and Baytrail: switch drivers to use raw spinlocks
in IRQ handlers to play nice with the realtime patch set.

- Rework and new modes handling for Qualcomm SPMI-MPP.

- Pinconf power source config for SH PFC.

New drivers and subdrivers:

- A new driver for Conexant Digicolor CX92755.

- A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5,
ProXtream2 and PH1-LD6b SoC pin control support.

- Reverse-egineered the S/PDIF settings for the Allwinner sun4i
driver.

- Support for Qualcomm Technologies QDF2xxx ARM64 SoCs

- A new Freescale i.mx6ul subdriver.

Cleanup:

- Remove platform data support in a number of SH PFC subdrivers"

pinctrl: nomadik: split stn8815 UART0 pin groups

Split the UART pin groups so we can activate RX/TX, CTS/RTS and

with function u0.

pinctrl: nomadik: depromote GPIO to subsystem_init()

2015-07-27T13:12:29+00:00

We no longer have to do GPIO initialization before the
pinctrl initialization, instead we can initialize the pinctrl
portions of the driver first and then the GPIO. Thus we can
move GPIO initialization to a subsystem_initcall(), but
not yet to a device_initcall().
