pinctrl: nomadik: Fix debugfs

2018-10-03T07:10:52+00:00

The .to_irq() function obviously takes the per-chip offset
as parameter, not the global GPIO number.

pinctrl: Include nothing else

2018-09-14T13:10:57+00:00

These drivers are GPIO drivers, and the do not need to use the
legacy header in , go directly for
 instead.

Replace any use of GPIOF_* with 0/1, these flags are for
consumers, not drivers.

Get rid of a few gpio_to_irq() users that was littering
around the place, use local callbacks or avoid using it at
all.

pinctrl: Convert to using %pOFn instead of device_node.name

2018-08-29T12:05:36+00:00

In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.

pinctrl: nomadik: silence uninitialized variable warning

2018-08-10T21:14:04+00:00

This is harmless, but "val" isn't necessarily initialized if
abx500_get_register_interruptible() fails.  I've re-arranged the code to
just return an error code in that situation.

pinctrl: nomadik: Drop U8540/9540 support

2018-03-23T02:38:14+00:00

The U8540 was an evolved version of the U8500, but it was never
mass produced or put into products, only reference designs exist.
The upstream support was never completed and it is unlikely that
this will happen so drop the support for now to simplify
maintenance of the U8500.

pinctrl: nomadik: add USB functions for STn8815

2018-02-13T07:18:17+00:00

The MUSB block in the Nomadik has two pin settings: high speed or
full speed. These correspond to two unique pin group settings: all
pins set to function B for high speed and all set to function C
for full speed. Full speed uses more pins than high speed.

pinctrl: abx500: Use seq_putc() in abx500_gpio_dbg_show()

2018-01-16T10:06:13+00:00

A single character (line break) should be put into a sequence.
Thus use the corresponding function "seq_putc".

This issue was detected by using the Coccinelle software.

pinctrl/nomadik/abx500: Improve a size determination in abx500_gpio_probe()

2017-12-21T09:20:29+00:00

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.

Merge tag 'gpio-v4.15-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

2017-11-15T01:23:44+00:00

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.15 kernel cycle:

  Core:

   - Fix the semantics of raw GPIO to actually be raw. No inversion
     semantics as before, but also no open draining, and allow the raw
     operations to affect lines used for interrupts as the caller
     supposedly knows what they are doing if they are getting the big
     hammer.

   - Rewrote the __inner_function() notation calls to names that make
     more sense. I just find this kind of code disturbing.

   - Drop the .irq_base() field from the gpiochip since now all IRQs are
     mapped dynamically. This is nice.

   - Support for .get_multiple() in the core driver API. This allows us
     to read several GPIO lines with a single register read. This has
     high value for some usecases: it can be used to create
     oscilloscopes and signal analyzers and other things that rely on
     reading several lines at exactly the same instant. Also a generally
     nice optimization. This uses the new assign_bit() macro from the
     bitops lib that was ACKed by Andrew Morton and is implemented for
     two drivers, one of them being the generic MMIO driver so everyone
     using that will be able to benefit from this.

   - Do not allow requests of Open Drain and Open Source setting of a
     GPIO line simultaneously. If the hardware actually supports
     enabling both at the same time the electrical result would be
     disastrous.

   - A new interrupt chip core helper. This will be helpful to deal with
     "banked" GPIOs, which means GPIO controllers with several logical
     blocks of GPIO inside them. This is several gpiochips per device in
     the device model, in contrast to the case when there is a 1-to-1
     relationship between a device and a gpiochip.

  New drivers:

   - Maxim MAX3191x industrial serializer, a very interesting piece of
     professional I/O hardware.

   - Uniphier GPIO driver. This is the GPIO block from the recent
     Socionext (ex Fujitsu and Panasonic) platform.

   - Tegra 186 driver. This is based on the new banked GPIO
     infrastructure.

  Other improvements:

   - Some documentation improvements.

   - Wakeup support for the DesignWare DWAPB GPIO controller.

   - Reset line support on the DesignWare DWAPB GPIO controller.

   - Several non-critical bug fixes and improvements for the Broadcom
     BRCMSTB driver.

   - Misc non-critical bug fixes like exotic errorpaths, removal of dead
     code etc.

   - Explicit comments on fall-through switch() statements"
