2025-04-16ufs: amd-versal2: Use raw read/write for SLCR/CACHE registersVenkatesh Yadav Abbarapu
Update the firmware driver UFS APIs zynqmp_pm_ufs_* to directly read/write to the pmc_iou_slcr and efuse_cache registers. Replace these raw reads/writes with the xilinx_pm_request() API with the correct arguments once the PM related changes are done.

2024-10-14ufs: core: remove link_startup_again logicNeil Armstrong
The link_startup_again logic was added in Linux to handle device that were set in LinkDown state, which should not be the case since U-boot doesn't set LinkDown state are init, and Linux sets the device active in ufshcd_init() for the first link startup. ufshcd_set_ufs_dev_active(hba) is called at ufshcd_init() right before scheduling an ufshcd_async_scan that will call ufshcd_device_init() then ufshcd_link_startup(). The comment in probe says: /* * We are assuming that device wasn't put in sleep/power-down * state exclusively during the boot stage before kernel. * This assumption helps avoid doing link startup twice during * ufshcd_probe_hba(). */ we can assume the same from U-Boot. While it worked to far, it breaks link startup for Qualcomm Controllers v5, let's just remove the logic.

2024-10-14ufs: split flush and invalidate to only invalidate when requiredNeil Armstrong
There is no need to flush and invalidate all data updated by the driver, mainly because on ARM platforms flush also invalidates the cachelines. Split the function in two and add the appropriate cacheline invalidates after the UFS DMA operation finishes to make sure we read from memory. Flushing then invalidating cacheline unaligned data causes data corruption issues on Qualcomm platforms, and is largely unnecessary anyway, so let's cleanup the cache operations.

2023-07-14ufs: Use 'TASK_TAG' to construct the ucd_req_ptr->header.dword_0Bhupesh Sharma
Instead of using the hard-coded value of 0x1f, use 'TASK_TAG' macro instead to construct the ucd_req_ptr->header.dword_0 This is in sync with what the Linux UFS driver does, i.e. set the byte0 equal to TASK_TAG (see [1]). Setting it to a fixed value of 0x1f is wrong as we define TASK_TAG as 0 inside u-boot ufs framework. So, instead we should use the macro value directly.

2023-05-06drivers: use dev_read_addr_ptr when cast to pointerJohan Jonker
The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU can expect 64-bit data from the device tree parser, so use dev_read_addr_ptr instead of the dev_read_addr function in the various files in the drivers directory that cast to a pointer. As we are there also streamline the error response to -EINVAL on return. Signed-off-by: Johan Jonker <jbx6244@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
