* arm: mvebu: add pin muxing options for the SDIO interface on Armada XPThomas Petazzoni2013-02-28
| | | | | | | | | | | | | | The SDIO interface is only available on pins MPP30/31/32/33/34/35 on the various Armada XP variants, so we provide a pin muxing option for this in the Armada XP .dtsi files. Even though those muxing options are the same for MV78230, MV78260 and MV78460, we keep them in each .dtsi file, because the number of pins, and therefore the declaration of the pinctrl node, is different for each SoC variant.

* arm: mvebu: use global interrupts for GPIOs on Armada XPThomas Petazzoni2013-01-08
| | | | | | | | | | | | | | | | | | | | | | | | The Armada XP GPIO controller has two ways of notifying interrupts: using global interrupts or using per-CPU interrupts. In an attempt to use the best available features, the 'marvell,armadaxp-gpio' compatible string selects a variant of the gpio-mvebu driver that makes use of the per-CPU interrupts. Unfortunately, this doesn't work properly in a SMP context, because we fall into cases where the GPIO interrupt is enabled on CPU X at the GPIO controller level, but on CPU Y at the interrupt controller level. It is not yet clear how to fix that easily. So for 3.8, our approach is to switch to global interrupts for GPIOs, so that we do not fall into this per-CPU interrupts problem. This patch therefore fixes GPIO interrupts on Armada XP platforms. Without this patch, GPIO interrupts simply do not work reliably, because their proper operation depends on which CPU the code requesting the interrupt is running.

* arm: mvebu: Armada XP MV78230 has two cores, not oneThomas Petazzoni2013-01-06
| | | | | | | | | | | Contrary to our understanding at the time armada-xp-mv78230.dtsi was written, the MV78230 variant of the Armada XP SoC has two cores and not one. This patch updates the .dtsi file to take into account this reality.

* arm: mvebu: add DT information for GPIO banks on Armada 370 and XPThomas Petazzoni2012-09-22
| | | | | | | | | | | | | | The gpioX aliases are needed so that the driver can use of_alias_get_id() to get a 0-based number of the GPIO bank, which we then use to compute the base GPIO of the bank being probed. This is similar to what gpio-mxs.c is doing.

* ARM: mvebu: Add pinctrl support to Armada XP SoCsThomas Petazzoni2012-09-22
This commits adds the necessary device tree information to define the compatible property for the pinctrl driver instance of Armada XP SoCs. Until now, the device tree representation considered the Armada XP as a single SoC. But in fact, there are three different SoCs in the Armada XP families, with different number of CPU cores, different number of Ethernet interfaces... and different number of muxable pins or functions. We therefore introduce three armada-xp-mv78xx0.dtsi for the three SoCs of the Armada XP family. The current armada-xp-db.dts evaluation board uses the MV78460 variant of the SoC.
