Compared to the .txt version, the YAML binding contains a new usage example with FCM NAND flash, and a full list of compatible strings based on current usage in arch/powerpc/boot/dts/. Note that the both the compatible strings and the unit address format are kept as-is, for compatibility with existing kernels and device trees, as well as unit address readability. This results in dts validation warnings: Warning (simple_bus_reg): /example-0/localbus@f0010100/board-control@1,0: simple-bus unit address format error, expected "100000000" Signed-off-by: J. Neusch=C3=A4fer --- V3: - move this patch after the GPCM/FCM patches to dtschema/dtc warnings due to missing bindings for fsl,elbc-gpcm-uio and fsl,elbc-fcm-nand - add "simple-bus" again, for compatibility with existing DTs/drivers based on discussion with Crystal Wood and Rob Herring - fix fsl,pq2-localbus compatible properties based on mgcoge.dts / ep8248e.= dts (was missing "simple-bus") - add board-control (bcsr) example again, now using the compatible string listed in Documentation/devicetree/bindings/board/fsl,bcsr.yaml - remove interrupt-parent property from example - rework the commit message V2: - fix order of properties in examples, according to dts coding style - move to Documentation/devicetree/bindings/memory-controllers - clarify the commit message a tiny bit - remove unnecessary multiline markers (|) - define address format in patternProperties - trim subject line (remove "binding") - remove use of "simple-bus", because it's technically incorrect --- .../bindings/memory-controllers/fsl,elbc.yaml | 158 +++++++++++++++++= ++++ .../devicetree/bindings/powerpc/fsl/lbc.txt | 43 ------ 2 files changed, 158 insertions(+), 43 deletions(-) diff --git a/Documentation/devicetree/bindings/memory-controllers/fsl,elbc.= yaml b/Documentation/devicetree/bindings/memory-controllers/fsl,elbc.yaml new file mode 100644 index 0000000000000000000000000000000000000000..620d7e7c62df35c754a01498391= d35ede03cdf87 --- /dev/null +++ b/Documentation/devicetree/bindings/memory-controllers/fsl,elbc.yaml @@ -0,0 +1,158 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/memory-controllers/fsl,elbc.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Freescale Enhanced Local Bus Controller + +maintainers: + - J.
