2011-12-12of: create of_phandle_args to simplify return of phandle parsing dataGrant Likely2-95/+94
of_parse_phandle_with_args() needs to return quite a bit of data. Rather than making each datum a separate **out_ argument, this patch creates struct of_phandle_args to contain all the returned data and reworks the user of the function. This patch also enables of_parse_phandle_with_args() to return the device node pointer for the phandle node. This patch also ends up being fairly major surgery to of_parse_handle_with_args(). The existing structure didn't work well when extending to use of_phandle_args, and I discovered bugs during testing. I also took the opportunity to rename the function to be like the existing of_parse_phandle(). v2: - moved declaration of of_phandle_args to fix compile on non-DT builds - fixed incorrect index in example usage - fixed incorrect return code handling for empty entries Reviewed-by: Shawn Guo <shawn.guo@freescale.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2011-12-07of/irq: Get rid of NO_IRQ usageAnton Vorontsov1-9/+4
PPC32/64 defines NO_IRQ to zero, so no problems expected. ARM defines NO_IRQ to -1, but OF code relies on IRQ domains support, which returns correct ('0') value in 'no irq' case. So everything should be fine. Other arches might break if some of their OF drivers rely on NO_IRQ being not 0. If so, the drivers must be fixed, finally.

2011-11-29of/irq: of_irq_init: add check for parent equal to child nodeRob Herring1-0/+2
With the revert of "of/irq: of_irq_find_parent: check for parent equal to child" (dc9372808412edb), we need another way to handle parent node equal to the child node. This can simply be handled in of_irq_init by checking for this condition.

2011-11-22Revert "of/irq: of_irq_find_parent: check for parent equal to child"Linus Torvalds1-7/+7
This reverts commit dc9372808412edbc653a675a526c2ee6c0c14a91. As requested by Ben Herrenschmidt: "This breaks some powerpc platforms at least. The practice of having a node provide an explicit "interrupt-parent" property pointing to itself is an old trick that we've used in the past to allow a device-node to have interrupts routed to different controllers. In that case, the node also contains an interrupt-map, so the node is its own parent, the interrupt resolution hits the map, which then can route each individual interrupt to a different parent." Grant says: "Ah, nuts, yes that is broken then. Yes, please revert the commit and Rob & I will come up with a better solution. Rob, I think it can be done by explicitly checking for np == desc->interrupt_parent in of_irq_init() instead of relying on of_irq_find_parent() returning NULL."

that should be the approved way of calculating the size of resources. No functional changes. Cc: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-07-28of/gpio: export of_gpio_simple_xlateJamie Iles1-2/+3
Allow GPIO drivers to use of_gpio_simple_xlate. This is useful for the generic GPIO driver for example where gpio_chip is embedded in bgpio_chip and doesn't need of_mm_gpio_chip but has a simple 1:1 GPIO mapping.

2011-07-27net: ibm_newemac: convert it to use of_get_phy_modeShawn Guo1-0/+2
The patch extends 'enum phy_interface_t' and of_get_phy_mode a little bit with PHY_INTERFACE_MODE_NA and PHY_INTERFACE_MODE_SMII added, and then converts ibm_newemac net driver to use of_get_phy_mode getting phy mode from device tree. It also resolves the namespace conflict on phy_read/write between common mdiobus interface and ibm_newemac private one. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Cc: David S.
