2024-05-07riscv: dts: microchip: add pac1934 power-monitor to icicleConor Dooley
The binding for this landed in v6.9, add the description. In the off-chance that there were people carrying local patches for this based on the driver shipped on the Microchip website (or vendor kernel) both the binding and sysfs filenames changed during upstreaming.

Pull SoC DT updates from Arnd Bergmann: "There is one new SoC for each 32-bit Arm and 64-bit RISC-V, but both the Rockchips rv1109 and Sopgho CV1812H are just minor variations of already supported chips. The other six new SoCs are all part of existing arm64 families, but are somewhat more interesting: - Samsung ExynosAutov920 is an automotive chip, and the first one we support based on the Cortex-A78AE core with lockstep mode. - Google gs101 (Tensor G1) is the chip used in a number of Pixel phones, and is grouped with Samsung Exynos here since it is based on the same SoC design, sharing most of its IP blocks with that series. - MediaTek MT8188 is a new chip used for mid-range tablets and Chromebooks, using two Cortex-A78 cores where the older MT8195 had four of them. - Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range phone SoC and the first supported chip based on Cortex-X4, Cortex-A720 and Cortex-A520. - Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest Laptop chip using the custom Oryon cores. - Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on Cortex-A76 and Cortex-A55 In terms of boards, we have - Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs. - Multiple Rockchips mobile gaming systems (Anbernic RG351V, Powkiddy RK2023, Powkiddy X55) along with the Sonoff iHost Smart Home Hub and a few Rockchips SBCs - Some ComXpress boards based on Marvell CN913x, which is the follow-up to Armada 7xxx/8xxx. - Six new industrial/embedded boards based on NXP i.MX8 and i.MX9 - Mediatek MT8183 based Chromebooks from Lenovo, Asus and Acer. - Toradex Verdin AM62 Mallow carrier for TI AM62 - Huashan Pi board based on the SophGo CV1812H RISC-V chip - Two boards based on Allwinner H616/H618 - A number of reference boards for various added SoCs from Qualcomm, Mediatek, Google, Samsung, NXP and Spreadtrum As usual, there are cleanups and warning fixes across all platforms as well as added features for several of them" * tag 'soc-dt-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (857 commits) ARM: dts: usr8200: Fix phy registers arm64: dts: intel: minor whitespace cleanup around '=' arm64: dts: socfpga: agilex: drop redundant status arm64: dts: socfpga: agilex: add unit address to soc node arm64: dts: socfpga: agilex: move firmware out of soc node arm64: dts: socfpga: agilex: move FPGA region out of soc node arm64: dts: socfpga: agilex: align pin-controller name with bindings arm64: dts: socfpga: stratix10_swvp: drop unsupported DW MSHC properties arm64: dts: socfpga: stratix10_socdk: align NAND chip name with bindings arm64: dts: socfpga: stratix10: add unit address to soc node arm64: dts: socfpga: stratix10: move firmware out of soc node arm64: dts: socfpga: stratix10: move FPGA region out of soc node arm64: dts: socfpga: stratix10: align pincfg nodes with bindings arm64: dts: socfpga: stratix10: add clock-names to DWC2 USB arm64: dts: socfpga: drop unsupported cdns,page-size and cdns,block-size ARM: dts: socfpga: align NAND controller name with bindings ARM: dts: socfpga: drop unsupported cdns,page-size and cdns,block-size arm64: dts: rockchip: Fix led pinctrl of lubancat 1 arm64: dts: rockchip: correct gpio_pwrctrl1 typo on nanopc-t6 arm64: dts: rockchip: correct gpio_pwrctrl1 typo on rock-5b ...
2023-12-06riscv: dts: microchip: add the mpfs' system controller qspi & associated flashConor Dooley
The system controller's flash can be accessed via an MSS-exposed QSPI controller sitting, which sits between the mailbox's control & data registers. On Icicle, it has an MT25QL01GBBB8ESF connected to it. The system controller and MSS both have separate QSPI controllers, both of which can access the flash, although the system controller takes priority. Unfortunately, on engineering sample silicon, such as that on Icicle kits, the MSS' QSPI controller cannot write to the flash due to a bug. As a workaround, a QSPI controller can be implemented in the FPGA fabric and the IO routing modified to connect it to the flash in place of the "hard" controller in the MSS.

2023-11-26riscv: dts: microchip: move timebase-frequency to mpfs.dtsiConor Dooley
The timebase-frequency on PolarFire SoC is not set by an oscillator on the board, but rather by an internal divider, so move the property to mpfs.dtsi. This looks to be copy-pasta from the SiFive Unleashed as the comments in both places were almost identical. In the Unleashed's case this looks to actually be valid, as the clock is provided by a crystal on the PCB.

2022-10-19riscv: dts: microchip: add the mpfs' fabric clock controlConor Dooley
The "fabric clocks" in current PolarFire SoC device trees are not really fixed clocks. Their frequency is set by the bitstream, so having them located in -fabric.dtsi is not a problem - they're just as "fixed" as the IP blocks etc used in the FPGA fabric. However, their configuration can be read at runtime (and to an extent they can be controlled, although the intended usage is static configurations set by the bitstream) through the system controller bus. In the v2022.09 icicle kit reference design a single CCC (north-west corner) is enabled, using a 50 MHz off-chip oscillator as its reference. Updating to the v2022.09 icicle kit reference design is required, as prior to this release, the CCC was not fixed & could change for any given run of the synthesis tool.

2022-09-27riscv: dts: microchip: update memory configuration for v2022.10Conor Dooley
In the v2022.10 reference design, the seg registers are going to be changed, resulting in a required change to the memory map in Linux. A small 4M reservation is made at the end of 32-bit DDR to provide some memory for the HSS to use, so that it can cache its payload.bin between reboots of a specific context.

2022-09-27riscv: dts: microchip: add pci dma ranges for the icicle kitConor Dooley
The recently removed, accidentally included, "matr0" property was used in place of a dma-ranges property. The PCI controller is non-functional with mainline Linux in the v2022.02 or later reference designs and has not worked without configuration of address-translation since v2021.08. Add the address translation that will be used by the v2022.09 reference design & update the compatible used by the dts. Since this change is not backwards compatible, update the compatible to denote this, jumping over v2022.09 directly to v2022.10. Signed-off-by: Conor Dooley <conor.dooley@microchip.com>
2022-08-23riscv: dts: microchip: mpfs: remove bogus card-detect-delayConor Dooley
Recent versions of dt-schema warn about a previously undetected undocumented property: arch/riscv/boot/dts/microchip/mpfs-icicle-kit.dtb: mmc@20008000: Unevaluated properties are not allowed ('card-detect-delay' was unexpected) From schema: Documentation/devicetree/bindings/mmc/cdns,sdhci.yaml There are no GPIOs connected to MSSIO6B4 pin K3 so adding the common cd-debounce-delay-ms property makes no sense. The Cadence IP has a register that sets the card detect delay as "DP * tclk". On MPFS, this clock frequency is not configurable (it must be 200 MHz) & the FPGA comes out of reset with this register already set.

2022-06-01riscv: dts: microchip: make the fabric dtsi board specificConor Dooley
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.
