* of/gpio: Implement of_gpio_count()Anton Vorontsov2008-12-211-0/+34
| | | | | | | | This function is used to count how many GPIOs are specified for a device node. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* of: of_parse_phandles_with_args() learns to differentiate 'hole' cellsAnton Vorontsov2008-12-211-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | Given this list (contains three gpio specifiers, one of which is a hole): gpios = <&phandle1 1 2 3 0 /* a hole */ &phandle2 4 5 6>; of_parse_phandles_with_args() would report -ENOENT for the `hole' specifier item, the same error value is used to report the end of the list, for example. Sometimes we want to differentiate holes from real errors -- for example when we want to count all the [syntax correct] specifiers. With this patch of_parse_phandles_with_args() will report -EEXITS when somebody requested to parse a hole. Also, make the out_{node,args} arguments optional, when counting we don't really need the out values.

* of/gpio: Implement of_get_gpio_flags()Anton Vorontsov2008-12-031-7/+29
| | | | | | | | | | | | | | This adds a new function, of_get_gpio_flags, which is like of_get_gpio(), but accepts a new "flags" argument. This new function will be used by the drivers that need to retrieve additional GPIO information, such as active-low flag. Also, this changes the default ("simple") .xlate routine to warn about bogus (< 2) #gpio-cells usage: the second cell should always be present for GPIO flags.

* of: Add helpers for finding device nodes which have a given propertyMichael Ellerman2008-11-191-0/+35
| | | | | | | | | | | | This commit adds a routine for finding a device node which has a certain property. The contents of the property are not taken into account, merely the presence or absence of the property. Based on that routine, we add a for_each_ macro for iterating over all nodes that have a certain property.

* OF-device: Don't overwrite numa_node in device registrationJeremy Kerr2008-10-311-1/+10
| | | | | | | | | | | | | | | | | Currently, the numa_node of OF-devices will be overwritten during device_register, which simply sets the node to -1. On cell machines, this means that devices can't find their IOMMU, which is referenced through the device's numa node. Set the numa node for OF devices with no parent, and use the lower-level device_initialize and device_add functions, so that the node is preserved. We can remove the call to set_dev_node in of_device_alloc, as it will be overwritten during register. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

The bindings specifies verbose information for the devices, but it doesn't fit in the I2C ID's 20 characters limit. The limit won't change[2], and the bindings won't change either as they're correct.

* powerpc/ibmebus: Restore "name" sysfs attribute on ibmebus devicesJoachim Fenkes2008-08-201-0/+10
| | | | | | | | | | | | | | | Recent of_platform changes made of_bus_type_init() overwrite the bus type's .dev_attrs list, meaning that the "name" attribute that ibmebus devices previously had is no longer present. This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER.

* | gpiolib: allow user-selectionMichael Buesch2008-07-251-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds functionality to the gpio-lib subsystem to make it possible to enable the gpio-lib code even if the architecture code didn't request to get it built in. The archtitecture code does still need to implement the gpiolib accessor functions in its asm/gpio.h file. This patch adds the implementations for x86 and PPC. With these changes it is possible to run generic GPIO expansion cards on every architecture that implements the trivial wrapper functions. Support for more architectures can easily be added.
