Subject: [PATCH v4 0/2] Xilinx Slave Serial FPGA Manager
This series adds an FPGA manager driver for Xilinx Spartan6 FPGAs
that can configure them using an SPI port and two GPIOs.
Anatolij Gustschin (2):
dt: bindings: fpga: add xilinx slave-serial binding description
fpga manager: Add Xilinx slave serial SPI driver
Changes in v4:
- add Acked-by tags for DT bindings
- increase program latency up to 7.5ms for other Xilinx FPGAs
- continue to apply CCLK cycles until specified timeout elapses (to
cover more possible configuration DONE scenarios)
- apply 8 CCLK cycles afer DONE signal
- rebased to apply on top of Kconfig/Makefile changes by queued
fpga manager patches
Changes in v3:
- extend example to show the usage in SPI master node, connected
to the fpga-region node
- use named constant for udelay()/usleep_range() arguments
- drop not needed .owner init
- correct module licence (GPL v2)
- fix build warning with newer gcc (in min() macro)
Changes in v2:
- corrected gpios properties and node name in example
in DT binding document
- rebased on v4.10
