Changes in v3 from the cover letter
* Reorder patches:
- Move generic queue migration to the beginning
- Move binding documentation before implementation
* Add a patch removing HAVE_CLK dependency
* Address the comments of Mark Brown:
- Move gpio request to probe() for compatibility with deferred gpio probing
- Extend spi_chip_sel() to handle chip-select deactivation
- devm_gpio_request_one() can't be used in probe() to also set direction and level, because we don't know the desired slave dependent chip-select polarity yet

Cover letter [PATCH v3 0/5] spi: dw: device tree and generic queue support
Unfortunately, I probably have no chance access to thest this series on hardware, I's only compile tested. So I'm sending this as RFC for code review. If this series doesn't get merged, it may be used at least as a starting point for someone with hardware access.
These patches add the following:
* Device tree support for the platform driver (dw-mmio)
* GPIO controlled chip-select implementing the generic SPI GPIO CS binding
* Generic queue migration
Comments are welcome.
v3:
* Reorder patches:
- Move generic queue migration to the beginning
- Move binding documentation before implementation
* Add a patch removing HAVE_CLK dependency
* Address the comments of Mark Brown:
- Move gpio request to probe() for compatibility with deferred gpio probing
- Extend spi_chip_sel() to handle chip-select deactivation
- devm_gpio_request_one() can't be used in probe() to also set direction and level, because we don't know the desired slave dependent chip-select polarity yet
v2:
* Use managed resources for GPIO allocation (Mark Brown)
* Add device tree binding documentation (Mark Brown)
