This series reworks the SSI bus framework for SPI and add some new SPI
controllers and devices:
Patches 1-4 reworks SSI to add chip-select support to SPI devices and allow for
multiple SPI devices attached to the
same bus.
Patches 5-6 fix the SPI setup in the stellaris machine model.
Patch 7 is a general FIFO helper API used by the upcomming patches.
Patch 8 is a device model for the m25p80 SPI flash family.
Patches 9 & 11 are the Xilinx SPI flash controller devices
Patches 10 & 12 add SPI controllers to the ML605 and Zynq machine models.
Patch 13 is Maintainerships.
Patch 14 Is a helper function that can SSI controllers can call to
automatically connect slave (based on QOM object heirachy) (New v8)
CHANGELOG:
changed from v7:
addressed PMM review (p5)
various minor bugfixes
Added connect children helper
changed from v6:
Address Blue Swirl Review (P8, P11)
changed from v5:
VMSD version bump
various line-by-line review fixes
removed trivial patch (formerly P8)
collapsed former P2-3 into one patch for bisectability
changed from v4 (Major changes):
Completely reworked SPI refactor. Please re-review from scratch.
Added Zynq SPI flash.
Factored out FIFO functionality from SPI flash controller.
changed from v3:
addressed reviewer comments from P Maydell and S Hajnoczi
added patch 5 (re Paul Brooks request)
changed from v2:
folded former SPI bus functionality into existing SSI infrastructure (suggested
- Paul Brook) (all patches)
made m25p80 use async io (suggested - Stefan Hajnoczi) (2/4)
instantiated two spi flashes instead of one in ml605 ref design (4/4)
changed from v1:
minor sylistic changes (1/4)
converted spi api to modified txrx style (1-3/4)
heavily refactored m25p80 model (2/4)
Peter A. G. Crosthwaite (13):
ssi: Support for multiple attached devices
ssi: Implemented CS behaviour
ssi: Added create_slave_no_init()
qdev: allow multiple qdev_init_gpio_in() calls
hw/stellaris: Removed gpio_out init array.
stellaris: Removed SSI mux
hw: Added generic FIFO API.
m25p80: Initial implementation of SPI flash device
xilinx_spi: Initial impl. of Xilinx SPI controller
petalogix-ml605: added SPI controller with n25q128
xilinx_spips: Xilinx Zynq SPI cntrlr device model
xilinx_zynq: Added SPI controllers + flashes
MAINTAINERS: Added maintainerships for SSI
Peter Crosthwaite (1):
ssi: Add slave autoconnect helper
