- Convert more DT code to use of_property_read_* API.
- Improve DT overlay support when adding multiple overlays.
- Convert printk's to %pOF format specifiers. Most went via subsystem
trees, but picked up the remaining orphans.
- Correct unittests to use preferred "okay" for "status" property value.
- Add a KASLR seed property.
- Vendor prefixes for Mellanox, Theobroma System, Adaptrum, Moxa.
- Fix modalias buffer handling.
- Clean-up of include paths for building dtbs.
- Add bindings for amc6821, isl1208, tsl2x7x, srf02, and srf10 devices.
- Add nvmem bindings for MediaTek MT7623 and MT7622 SoC.
- Add compatible string for Allwinner H5 Mali-450 GPU.
- Fix links to old OpenFirmware docs with new mirror on devicetree.org.
- Remove status property from binding doc examples.

Renesas MSIOF spi controller
|
|
|
|
Required properties:
|
|
- compatible : "renesas,msiof-r8a7790" (R-Car H2)
|
|
"renesas,msiof-r8a7791" (R-Car M2-W)
|
|
"renesas,msiof-r8a7792" (R-Car V2H)
|
|
"renesas,msiof-r8a7793" (R-Car M2-N)
|
|
"renesas,msiof-r8a7794" (R-Car E2)
|
|
"renesas,msiof-r8a7795" (R-Car H3)
|
|
"renesas,msiof-r8a7796" (R-Car M3-W)
|
|
"renesas,msiof-sh73a0" (SH-Mobile AG5)
|
|
"renesas,sh-mobile-msiof" (generic SH-Mobile compatibile device)
|
|
"renesas,rcar-gen2-msiof" (generic R-Car Gen2 compatible device)
|
|
"renesas,rcar-gen3-msiof" (generic R-Car Gen3 compatible device)
|
|
"renesas,sh-msiof" (deprecated)
|
|
|
|
When compatible with the generic version, nodes
|
|
must list the SoC-specific version corresponding
|
|
to the platform first followed by the generic
|
|
version.
|
|
|
|
- reg : A list of offsets and lengths of the register sets for
|
|
the device.
|
|
If only one register set is present, it is to be used
|
|
by both the CPU and the DMA engine.
|
|
If two register sets are present, the first is to be
|
|
used by the CPU, and the second is to be used by the
|
|
DMA engine.
|
|
- interrupt-parent : The phandle for the interrupt controller that
|
|
services interrupts for this device
|
|
- interrupts : Interrupt specifier
|
|
- #address-cells : Must be <1>
|
|
- #size-cells : Must be <0>
|
|
|
|
Optional properties:
|
|
- clocks : Must contain a reference to the functional clock.
|
|
- num-cs : Total number of chip-selects (default is 1)
|
|
- dmas : Must contain a list of two references to DMA
|
|
specifiers, one for transmission, and one for
|
|
reception.
|
|
- dma-names : Must contain a list of two DMA names, "tx" and "rx".
|
|
- spi-slave : Empty property indicating the SPI controller is used
|
|
in slave mode.
|
|
- renesas,dtdl : delay sync signal (setup) in transmit mode.
|
|
Must contain one of the following values:
|
|
0 (no bit delay)
|
|
50 (0.5-clock-cycle delay)
|
|
100 (1-clock-cycle delay)
|
|
150 (1.5-clock-cycle delay)
|
|
200 (2-clock-cycle delay)
|
|
|
|
- renesas,syncdl : delay sync signal (hold) in transmit mode.
|
|
Must contain one of the following values:
|
|
0 (no bit delay)
|
|
50 (0.5-clock-cycle delay)
|
|
100 (1-clock-cycle delay)
|
|
150 (1.5-clock-cycle delay)
|
|
200 (2-clock-cycle delay)
|
|
300 (3-clock-cycle delay)
|
|
|
|
Optional properties, deprecated for soctype-specific bindings:
|
|
- renesas,tx-fifo-size : Overrides the default tx fifo size given in words
|
|
(default is 64)
|
|
- renesas,rx-fifo-size : Overrides the default rx fifo size given in words
|
|
(default is 64)
|
|
|
|
Pinctrl properties might be needed, too. See
|
|
Documentation/devicetree/bindings/pinctrl/renesas,*.

Example:
|
|
|
|
msiof0: spi@e6e20000 {
|
|
compatible = "renesas,msiof-r8a7791",
|
|
"renesas,rcar-gen2-msiof";
|
|
reg = <0 0xe6e20000 0 0x0064>;
|
|
interrupts = <0 156 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&mstp0_clks R8A7791_CLK_MSIOF0>;
|
|
dmas = <&dmac0 0x51>, <&dmac0 0x52>;
|
|
dma-names = "tx", "rx";
|

|
#size-cells = <0>;
