sh-pfc: Move driver from drivers/sh/ to drivers/pinctrl/

sh: pfc: Shuffle PFC support core.

2012-07-10T02:49:30+00:00

This follows the intc/clk changes and shuffles the PFC support code under its own directory. This will facilitate better code sharing, and allow us to trim down the exported interface by quite a margin. Signed-off-by: Paul Mundt

sh: pfc: Make gpio chip support optional where possible.

2012-06-20T09:17:56+00:00

This implements some Kconfig knobs for ensuring that the PFC gpio chip can be disabled or built as a module in the cases where it's optional, or forcibly enabled in cases where it's not. Signed-off-by: Paul Mundt

sh: intc: Split up the INTC code.

2010-10-05T13:10:30+00:00

This splits up the sh intc core in to something more vaguely resembling a subsystem. Most of the functionality was alread fairly well compartmentalized, and there were only a handful of interdependencies that needed to be resolved in the process. This also serves as future-proofing for the genirq and sparseirq rework, which will make some of the split out functionality wholly generic, allowing things to be killed off in place with minimal migration pain.

sh: intc: Implement reverse mapping for IRQs to per-controller IDs.

2010-10-04T16:15:47+00:00

This implements a scheme roughly analogous to the PowerPC virtual to hardware IRQ mapping, which we use for IRQ to per-controller ID mapping. This makes it possible for drivers to use the IDs directly for lookup instead of hardcoding the vector. The main motivation for this work is as a building block for dynamically allocating virtual IRQs for demuxing INTC events sharing a single INTEVT in addition to a common masking source.

sh: Support IRQ balancing for SH-X3 proto cores, too.

2010-10-01T16:04:30+00:00

This adds in hardware IRQ auto-distribution support for SH-X3 proto CPUs, following the SH7786 support. Signed-off-by: Paul Mundt

sh: intc: IRQ auto-distribution support.

2010-04-15T04:13:52+00:00

This implements support for hardware-managed IRQ balancing as implemented by SH-X3 cores (presently only hooked up for SH7786, but can probably be carried over to other SH-X3 cores, too). CPUs need to specify their distribution register along with the mask definitions, as these follow the same format. Peripheral IRQs that don't opt out of balancing will be automatically distributed at the whim of the hardware block, while each CPU needs to verify whether it is handling the IRQ or not, especially before clearing the mask.

sh: intc: userimask support.

2010-04-13T05:43:03+00:00

This adds support for hardware-assisted userspace irq masking for special priority levels. Due to the SR.IMASK interactivity, only some platforms implement this in hardware (including but not limited to SH-4A interrupt controllers, and ARM-based SH-Mobile CPUs). Each CPU needs to wire this up on its own, for now only SH7786 is wired up as an example. Signed-off-by: Paul Mundt
