The Toumaz Xenif TZ1090 SoC (AKA Comet) contains a 2-threaded Linux-capable HTP (Meta 2), and is found in a number of development boards and digital radios, such as the Minimorph Development Platform.
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 I aim to get whatever I can of this patchset into v3.10 (at least the first two patches) so all review is very much appreciated.
