Subject: Applied "spi: dt-bindings: Convert spi-sifive binding to json-schema" to the spi tree
The patch
spi: dt-bindings: Convert spi-sifive binding to json-schema
has been applied to the spi tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-5.5
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark

-SiFive SPI controller Device Tree Bindings
-------------------------------------------
-
-Required properties:
-- compatible : Should be "sifive,<chip>-spi" and "sifive,spi<version>".
- Supported compatible strings are:
- "sifive,fu540-c000-spi" for the SiFive SPI v0 as integrated
- onto the SiFive FU540 chip, and "sifive,spi0" for the SiFive
- SPI v0 IP block with no chip integration tweaks.
- Please refer to sifive-blocks-ip-versioning.txt for details
-- reg : Physical base address and size of SPI registers map
- A second (optional) range can indicate memory mapped flash
-- interrupts : Must contain one entry
-- interrupt-parent : Must be core interrupt controller
-- clocks : Must reference the frequency given to the controller
-- #address-cells : Must be '1', indicating which CS to use
-- #size-cells : Must be '0'
-
-Optional properties:
-- sifive,fifo-depth : Depth of hardware queues; defaults to 8
-- sifive,max-bits-per-word : Maximum bits per word; defaults to 8
-
-SPI RTL that corresponds to the IP block version numbers can be found here:
-https://github.com/sifive/sifive-blocks/tree/master/src/main/scala/devices/spi
-
-Example:
- spi: spi@...40000 {
- compatible = "sifive,fu540-c000-spi", "sifive,spi0";
- reg = <0x0 0x10040000 0x0 0x1000 0x0 0x20000000 0x0 0x10000000>;
- interrupt-parent = <&plic>;
- interrupts = <51>;
- clocks = <&tlclk>;
- #address-cells = <1>;
- #size-cells = <0>;
- sifive,fifo-depth = <8>;
- sifive,max-bits-per-word = <8>;
- };
