* mfd: core: Push irqdomain mapping out into devicesMark Brown2012-09-151-1/+1
| | | | | | | | | | | | | | | | | | | | | Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

There are some patches in here outside of drivers/staging/, notibly the iio code (which is still stradeling the staging / not staging boundry), the pstore code, and the tracing code. All of these have gotten acks from the various subsystem maintainers to be included in this tree. The pstore and tracing patches are related, and are coming here as they replace one of the android staging drivers. Otherwise, the normal staging mess.

| * staging: nvec: rename led driver to board specific paz00 driverMarc Dietrich2012-06-251-1/+1
| | | | | | | | | | | | | | | | | | The led driver used OEM commands which are not part of the nvec protocol definition. Therefore it is renamed to nvec_paz00 to reflect that it only applies to PAZ00 board based devices.

* staging: nvec: Allow TX buffers only in the upper 75% of the poolJulian Andres Klode2011-09-301-6/+25
| | | | | | | | | | | | | | | | | Allow TX buffers to be allocated only in the upper 75% of the pool to avoid a completely filled buffer preventing the driver from processing responses. This also improves performance, as RX allocations do not require checking buffers allocated for TX unless there are more than 16 incoming messages -- which is highly unlikely. An earlier version used the lower 75% for TX messages, but that was considered to be not that effective due to the overlaps of RX and TX buffers mentioned above.
