2026-02-13pinctrl: zynqmp: Add SPL supportSean Anderson
Although the pinctrl pm requests are implemented in the PMU firmware, PM_QUERY_DATA is actually implemented in ATF. In SPL (or when running in EL3), ATF is not yet running, so we need to implement this API ourselves. Do the bare minimum, allowing SPL to enumerate functions, but don't bother with groups. Groups take up a lot of space, and can be emulated with pins. For example, a node like display-port { mux { groups = "dpaux0_1"; function = "dpaux0"; }; }; can be replaced by display-port { mux { pins = "MIO34", "MIO35", "MIO36", "MIO37"; function = "dpaux0"; }; }; While this isn't backwards-compatible with existing devicetrees, it's more than enough for SPL where we may only need to mux one or two pins. Add SPL_PINCTRL_ZYNQMP to ensure there's no SPL size growth when pinctrl is enabled in U-Boot but isn't necessary for SPL. The only config this would affect is Kria, but SPL_PINCTRL_GENERIC is disabled so SPL_PINCTRL_ZYNQMP is not selected.

2025-12-19xilinx: versal: Get rid of xlnx-versal-power.h from bindingsMichal Simek
Remove xlnx-versal-power.h dt binding header because they should be moved directly to folder where DTs are. In the Linux kernel this shift already started by moving xlnx-zynqmp-clk.h to arch/arm64/boot/dts/xilinx/ folder. U-Boot is using only one PD_DEV_OSPI constact which is moved to zynqmp_firmware.h header. But handling around it should be fixed anyway because no driver should be calling xilinx_pm_request() directly.

Versal Gen 2 is using different SMC format that's why firmware and clock drivers needs to be align with it. Signed-off-by: Michal Simek <[email protected]> Link: https://lore.kernel.org/r/16bdee56fd75113c6d531bae7a8a34900b10280d.1762788250.git.michal.simek@amd.com
2025-10-09drivers: firmware: update xilinx_pm_request to support max payloadNaman Trivedi
Currently xilinx_pm_request API supports four u32 payloads. However the legacy SMC format supports five u32 request payloads and extended SMC format supports six u32 request payloads. Add support for the same in xilinx_pm_request API. Also add two dummy arguments to all the callers of xilinx_pm_request. The TF-A always fills seven u32 return payload so add support for the same in xilinx_pm_request API.

2025-04-16xilinx: versal: add firmware access to PMC multi Boot mode registerPrasad Kummari
Added extended support for retrieving the PMC muti boot mode register via the firmware interface, which is preferred when U-Boot runs in EL2 and cannot directly access PMC registers via raw reads. Ideally, all secure registers should be accessed via xilinx_pm_request(). Introduced the secure zynqmp_pm_get_pmc_multi_boot_reg() call, which uses xilinx_pm_request() to read the PMC multi boot mode register. BootROM increments the MultiBoot register (PMC_MULTI_BOOT) read address offset by 32 KB and retries. For SD and eMMC boot modes, it can search up to 8191 FAT files for the identification string. A 13-bit mask (0x1FFF) is applied to PMC_MULTI_BOOT_MASK to obtain the correct values in BootROM.

Ideally, all secure registers should be accessed via xilinx_pm_request(). Introduced the secure zynqmp_pm_get_bootmode_reg() call, which uses xilinx_pm_request() to read the boot mode register. When CONFIG_ZYNQMP_FIRMWARE is enabled, the secure zynqmp_pm_get_bootmode_reg() call is used; otherwise, direct raw reads are performed in the case of mini U-Boot.

2022-06-29spi: cadence-qspi: reset qspi flash for versal platformT Karthik Reddy
When flash operated at non default mode like DDR, flash need to be reset to operate in SDR mode to read flash ids by spi-nor framework. Reset the flash to the default state before using the flash. This reset is handled by a gpio driver, in case of mini U-Boot as gpio driver is disabled, we do raw read and write access by the registers. Versal platform utilizes spi calibration for read delay programming, so incase by default read delay property is set in DT. We make sure not to use read delay from DT by overwriting read_delay with -1.
