These checks help ensure that GPIOs have been properly initialized
|
|
|
|
|
before they are used, and that sleeping calls are not made from
|
|
|
|
|
non-sleeping contexts. They can make bitbanged serial protocols

slower. The diagnostics help catch the type of setup errors

that are most common when setting up new platforms or boards.

gpio: sysfs interface
This adds a simple sysfs interface for GPIOs.
/sys/class/gpio
/export ... asks the kernel to export a GPIO to userspace
/unexport ... to return a GPIO to the kernel
/gpioN ... for each exported GPIO #N
/value ... always readable, writes fail for input GPIOs
/direction ... r/w as: in, out (default low); write high, low
/gpiochipN ... for each gpiochip; #N is its first GPIO
/base ... (r/o) same as N
/label ... (r/o) descriptive, not necessarily unique
/ngpio ... (r/o) number of GPIOs; numbered N .. N+(ngpio - 1)
GPIOs claimed by kernel code may be exported by its owner using a new
gpio_export() call, which should be most useful for driver debugging.
Such exports may optionally be done without a "direction" attribute.
Userspace may ask to take over a GPIO by writing to a sysfs control file,
helping to cope with incomplete board support or other "one-off"
requirements that don't merit full kernel support:
echo 23 > /sys/class/gpio/export
... will gpio_request(23, "sysfs") and gpio_export(23);
use /sys/class/gpio/gpio-23/direction to (re)configure it,
when that GPIO can be used as both input and output.
echo 23 > /sys/class/gpio/unexport
... will gpio_free(23), when it was exported as above
The extra D-space footprint is a few hundred bytes, except for the sysfs
resources associated with each exported GPIO. The additional I-space
footprint is about two thirds of the current size of gpiolib (!). Since
no /dev node creation is involved, no "udev" support is needed.
Related changes:
* This adds a device pointer to "struct gpio_chip". When GPIO
providers initialize that, sysfs gpio class devices become children of
that device instead of being "virtual" devices.
* The (few) gpio_chip providers which have such a device node have
been updated.
* Some gpio_chip drivers also needed to update their module "owner"
field ... for which missing kerneldoc was added.
* Some gpio_chips don't support input GPIOs. Those GPIOs are now
flagged appropriately when the chip is registered.
Based on previous patches, and discussion both on and off LKML.
A Documentation/ABI/testing/sysfs-gpio update is ready to submit once this
merges to mainline.

This is mostly useful to work around omissions in a system's
|
|
|
|
|
kernel support. Those are common in custom and semicustom
|
|
|
|
|
hardware assembled using standard kernels with a minimum of
|
|
|
|
|
custom patches. In those cases, userspace code may import
|
|
|
|
|
a given GPIO from the kernel, if no kernel driver requested it.
|
|
|
|
|
|
|
|
|
|
Kernel drivers may also request that a particular GPIO be
|
|
|
|
|
exported to userspace; this can be useful when debugging.

(Cougar Point), and NM10 (Tiger Point).
Additional Intel chipsets should be easily supported if needed, eg the
ICH1-5, EP80579, etc.
Tested on QM67 (Cougar Point), QM57 (Ibex Peak), 3100 (Whitmore Lake),
and NM10 (Tiger Point).
Includes work from Jean Delvare:
- Resource leak removal during module load/unload
- GPIO API bit value enforcement
Also includes code cleanup from Guenter Roeck and Grant Likely.

gpio: add LP3943 I2C GPIO expander driver
This is one of LP3943 MFD driver.
LP3943 is configurable as a GPIO expander, up to 16 GPIOs.
* Application note: how to configure LP3943 as a GPIO expander
http://www.ti.com/lit/an/snva287a/snva287a.pdf
* Supported GPIO controller operations
request, free, direction_input, direction_output, get and set
* GPIO direction register not supported
LP3943 doesn't have the GPIO direction register. It only provides input and
output status registers.
So, private data for the direction should be handled manually.
This variable is updated whenever the direction is changed and
used in 'get' operation.
* Pin assignment
A driver data, 'pin_used' is checked when a GPIO is requested.
If the GPIO is already assigned, then returns as failure.
If the GPIO is available, 'pin_used' is set.
When the GPIO is not used anymore, then it is cleared.
It is defined as unsigned long type for atomic bit operation APIs,
but only LSB 16bits are used because LP3943 has 16 outputs.

Your board setup code will need to declare the expanders in

use, and assign numbers to the GPIOs they expose. Those GPIOs
|
|
|
|
|
can then be used from drivers and other kernel code, just like
|
|
|
|
|
other GPIOs, but only accessible from task contexts.
|
|
|
|
|
|
|
|

This driver provides an in-kernel interface to those GPIOs using
|
|
|
|
|
platform-neutral GPIO calls.
