* of/mdio: Add support function for Ethernet fixed-link propertyAnton Vorontsov2009-07-221-0/+42
| | | | | | | | | | | | | | | | | Fixed-link support is broken for the ucc_eth, gianfar, and fs_enet device drivers. The "OF MDIO rework" patches removed most of the support. Instead of re-adding fixed-link stuff to the drivers, this patch adds a support function for parsing the fixed-link property and obtaining a dummy phy to match. Note: the dummy phy handling in arch/powerpc is a bit of a hack and needs to be reworked. This function is being added now to solve the regression in the Ethernet drivers, but it should be considered a temporary measure until the fixed link handling can be reworked.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for parsing the device tree for PHY devices on an MDIO bus. Currently many of the PowerPC ethernet drivers are open coding a solution for reading data out of the device tree to find the correct PHY device. This patch implements a set of common routines to: a) let MDIO bus drivers register phy_devices described in the tree, and b) let MAC drivers find the correct phy_device via the tree.

| | | | | | | | | | | | | | | | | | | | | | | | 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-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>

* [POWERPC] i2c: Fix build breakage introduced by OF helpersJochen Friedrich2008-04-203-3/+3
| | | | | | | | | | | | | Fix build breakage introduced in commit "[POWERPC] i2c: OF helpers for the i2c API". If i2c-core is compiled as a module, the helper needs to be compiled as a module, as well. Rename i2c.c to of_i2c.c to avoid name space conflict. [paulus@samba.org: Changed dependency from OF to PPC_OF to avoid sparc{32,64} allmodconfig breakage.] Signed-off-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] OF helpers for the GPIO APIAnton Vorontsov2008-04-163-0/+249
| | | | | | | | | | | | | | | | | | | This implements various helpers to support OF bindings for the GPIO LIB API. Previously this was PowerPC specific, but it seems this code isn't arch-dependent anyhow, so let's place it into of/. SPARC will not see this addition yet, real hardware seem to not use GPIOs at all. But this might change: http://www.leox.org/docs/faq_MLleon.html "16-bit I/O port" sounds promising. :-) Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Acked-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Add of_device_is_available functionJosh Boyer2008-04-071-0/+26
| | | | | | | | | | | | | | IEEE 1275 defined a standard "status" property to indicate the operational status of a device. The property has four possible values: okay, disabled, fail, fail-xxx. The absence of this property means the operational status of the device is unknown or okay. This adds a function called of_device_is_available that checks the state of the status property of a device. If the property is absent or set to either "okay" or "ok", it returns 1. Otherwise it returns 0. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] Add of_get_next_parent()Michael Ellerman2008-02-061-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | Iterating through a device node's parents is simple enough, but dealing with the refcounts properly is a little ugly, and replicating that logic is asking for someone to get it wrong or forget it all together, eg: while (dn != NULL) { /* loop body */ tmp = of_get_parent(dn); of_node_put(dn); dn = tmp; } So add of_get_next_parent(), inspired by of_get_next_child(). The contract is that it returns the parent and drops the reference on the current node, this makes the loop look like: while (dn != NULL) { /* loop body */ dn = of_get_next_parent(dn); } Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Acked-by: David S.
