This patchset adds some core infrastructure for the TZ1090, including drivers for the powerdown controller (PDC) irqchip, general/PDC pin controllers, and general/PDC GPIO controllers. It's not yet enough to get the UARTs going (no common clock framework) so JTAG/QEMU with DA TTY is still needed to get a shell. A QEMU with a Meta frontend and some TZ1090 emulation, and the SoC Technical Reference Manual which documents the registers used by both GPIO drivers and both pin control drivers can be downloaded from the Minimorph SDK (registration of a Minimorph is currently required): http://imgtec.com/meta_insider/metaflow-sdk.asp Changes in v2: There've been plenty of changes since v1 (thanks for all the feedback!) so I think it's time for v2.

Yes, I believe there are e.g. both a2r10g10b10 and b10g10r10a2 for example, and it's quite common to replace a with x, especially for scanout buffers. Google certainly has hits for that. Using just an error-return is probably fine. I was going to say that the table lookup might propagate a NULL all the way through to that check, and hence require both checks above, but I guess that case can't happen, since if there is no table entry, then simplefb_parse_format() will always be called, so that's fine. </pre> Stephen Warren 2013-05-24T15:37:42 http://permalink.gmane.org/gmane.linux.drivers.devicetree/36488 <pre> :) You can.

The helper that allocates the bridge functions requires an additional parameter allowing to request component specific functions that need not be initialized through device tree bindings but just using simple look-up and statically defined constants. This patch introduces the necessary changes to the vexpress config layer to cater for the new vexpress bridge interface requirements.
