2024-04-29arm/arm64: dts: Drop "arm,armv8-pmuv3" compatible usageRob Herring
The "arm,armv8-pmuv3" compatible is intended only for s/w models. Primarily, it doesn't provide any detail on uarch specific events. There's still remaining cases for CPUs without any corresponding PMU definition and for big.LITTLE systems which only have a single PMU node (there should be one per core type).

Add u-boot options node with details about bootscr-address. c&p description from dtschema/schemas/options/u-boot.yaml: "Holds the full address of the boot script file. It helps in making automated flow easier by fetching the 64bit address directly from DT. Value should be automatically copied to the U-Boot 'scriptaddr' variable. When it is defined, bootscr-ram-offset property should be ignored. Actually only one of them should be present in the DT." Address is generic for all zynqmp boards because all of them have DDR starting from 0. Custom boards should revisit the location and aligned it based on their needs.

2023-05-16arm64: xilinx: Use zynqmp prefix for SOM dt overlaysMichal Simek
U-Boot is using zynqmp- prefix to compose DT name for board detection that's why also generate DT in this format in the kernel. Signed-off-by: Michal Simek <michal.simek@amd.com> Link: https://lore.kernel.org/r/49c1b8c992929610ba17b9c6edf5d40d4b28d2ed.1683033163.git.michal.simek@amd.com
2023-05-16arm64: zynqmp: Add phase tags markingMichal Simek
bootph-all as phase tag was added to dt-schema (dtschema/schemas/bootph.yaml) to cover U-Boot challenges with DT. That's why add it also to Linux to be aligned with bootloader requirement.

2023-05-16arm64: zynqmp: Describe bus-width for SD card on KV260Michal Simek
SD card is connected with 4 data lines which should be described properly. Signed-off-by: Michal Simek <michal.simek@amd.com> Link: https://lore.kernel.org/r/b4046d2f593047400c190e438fd9d05128c293d9.1683034376.git.michal.simek@amd.com
2023-05-16arm64: zynqmp: Enable AMS on SOM and other zcu10x boardsMichal Simek
AMS is used for monitoring system. Used for measuring voltages and especially temperatures. Origin interface is IIO but via iio-hwmon it can be moved to hwmon framework too (done for SOM and zcu100).

2023-05-16arm64: zynqmp: Enable DP driver for SOMsMichal Simek
DP DMA is already enabled that's why there is no reason to keep DP disabled. Signed-off-by: Michal Simek <michal.simek@amd.com> Link: https://lore.kernel.org/r/15d16b4de933bfae108df6ca368eb2cdf916aa02.1683034376.git.michal.simek@amd.com
2023-05-16arm64: zynqmp: Setup clock for DP and DPDMAMichal Simek
Clocks are coming from shared HW design where these frequencies should be aligned with PLL setup. Signed-off-by: Michal Simek <michal.simek@amd.com> Link: https://lore.kernel.org/r/807e22371394222f728ff7d6b190a96a12145439.1683034376.git.michal.simek@amd.com
2023-05-16arm64: zynqmp: Switch to ethernet-phy-id in kv260Michal Simek
Use ethernet-phy-id compatible string to properly describe phy reset on kv260 boards. Previous description wasn't correct because reset was done for mdio bus to operate and it was in this case used for different purpose which was eth phy reset. With ethernet-phy-id phy reset happens only for the phy via phy framework.

2023-05-16arm64: zynqmp: Add pinctrl emmc description to SM-K26Michal Simek
Production SOM has emmc on it and make sense to describe pin description to be able use EMMC if it is not configured via psu_init.
