This patchset adds mailbox framework integration for the Xilinx LogiCORE IP
mailbox. The Xilinx LogiCORE IP mailbox is a fpga softcore that allows
interprocessor communication between AXI4 stream / memory mapped
processors.
Changes from v4:
- Have separate mbox_ops structs for polling / irq mode
- Moved clk handling to startup / shutdown
- Embedded struct mbox_chan in struct xilinx_mbox
- Fixed mbox-cells in devicetree documentation
- Misc stylistic issues
Changes from v3:
- Stylistic changes
- Changed reg size in dts to 0x100
Changes from v2:
- Fixed error condition for IRQ from >= 0 to > 0
- Fixed clock enable
- Cleaned up docs
Changes from v1:
- Added common clock framework support
- Deal with IRQs that happend before driver load,
since HW will not let us know about them when we enable IRQs
Changes from v0:
- Several stylistic issues
- Dropped superfluous intr_mode member
- Really masking the IRQs on mailbox_shutdown
- No longer using polling by accident in non-IRQ mode
- Swapped doc and driver commits
Happy hacking,
Moritz
