riscv: dts: microchip: re-add pdma to mpfs device tree

2022-06-12T18:33:52Z

PolarFire SoC /does/ have a SiFive pdma, despite what I suggested as a conflict resolution to Zong. Somehow the entry fell through the cracks between versions of my dt patches, so re-add it with Zong's updated compatible & dma-channels property.

riscv: dts: icicle: sort nodes alphabetically

2022-06-01T22:28:51Z

The icicle device tree is in a "random" order, so clean it up and sort its elements alphabetically to match the newly added PolarBerry dts.

riscv: microchip: icicle: readability fixes

2022-06-01T22:28:40Z

Fix the sort order of the status properties, remove some extra whitespace in the mmc entry & add whitespace to the mac entry containing the phys so that the dt is easier to read.

riscv: dts: microchip: make the fabric dtsi board specific

2022-06-01T22:28:11Z

Currently mpfs-fabric.dtsi is included by mpfs.dtsi - which is fine currently since there is only one board with this SoC upstream. However if another board was added, it would include the fabric contents of the Icicle Kit's reference design. To avoid this, rename mpfs-fabric.dtsi to mpfs-icicle-kit-fabric.dtsi & include it in the dts rather than mpfs.dtsi. mpfs-icicle-kit-fabric.dtsi specifically matches the 22.03 reference design for the icicle kit's FPGA fabric & an older version of the design may not have the i2c or pwm devices - so add the compatible string to document this.

riscv: dts: microchip: remove soc vendor from filenames

2022-06-01T22:27:54Z

Having the SoC vendor both as the directory and in the filename adds little. Remove microchip from the filenames so that the files will resemble the other directories in riscv (and arm64). The new names follow a soc-board.dts & soc{,-fabric}.dtsi pattern.
