arch/powerpc/sysdev/qe_lib/qe.c: Add of_node_put to avoid memory leak

2010-08-31T21:41:03+00:00

Add a call to of_node_put in the error handling code following a call to
of_find_compatible_node.

The semantic match that finds this problem is as follows:

powerpc: remove references to of_device and to_of_device

2010-07-24T15:58:21+00:00

of_device is just a #define alias to platform_device.  This patch
replaces all references to it with platform_device.

of/gpio: add default of_xlate function if device has a node pointer

2010-07-05T22:14:30+00:00

Implement generic OF gpio hooks and thus make device-enabled GPIO chips
(i.e.  the ones that have gpio_chip->dev specified) automatically attach
to the OpenFirmware subsystem.  Which means that now we can handle I2C and
SPI GPIO chips almost* transparently.

* "Almost" because some chips still require platform data, and for these
  chips OF-glue is still needed, though with this change the glue will
  be much smaller.

of/gpio: stop using device_node data pointer to find gpio_chip

2010-07-05T22:14:30+00:00

Currently the kernel uses the struct device_node.data pointer to resolve
a struct gpio_chip pointer from a device tree node.  However, the .data
member doesn't provide any type checking and there aren't any rules
enforced on what it should be used for.  There's no guarantee that the
data stored in it actually points to an gpio_chip pointer.

Instead of relying on the .data pointer, this patch modifies the code
to add a lookup function which scans through the registered gpio_chips
and returns the gpio_chip that has a pointer to the specified
device_node.

of/gpio: Kill of_gpio_chip and add members directly to gpio_chip

2010-07-05T22:14:30+00:00

The OF gpio infrastructure is great for describing GPIO connections within
the device tree.  However, using a GPIO binding still requires changes to
the gpio controller just to add an of_gpio structure.  In most cases, the
gpio controller doesn't actually need any special support and the simple
OF gpio mapping function is more than sufficient.  Additional, the current
scheme of using of_gpio_chip requires a convoluted scheme to maintain
1:1 mappings between of_gpio_chip and gpio_chip instances.

If the struct of_gpio_chip data members were moved into struct gpio_chip,
then it would simplify the processing of OF gpio bindings, and it would
make it trivial to use device tree OF connections on existing gpiolib
controller drivers.

This patch eliminates the of_gpio_chip structure and moves the relevant
fields into struct gpio_chip (conditional on CONFIG_OF_GPIO).  This move
simplifies the existing code and prepares for adding automatic device tree
support to existing drivers.
