* ufs: allow UFSHCI version 4.0Neil Armstrong2024-10-141-1/+2

* ufs: add get_max_pwr_mode callbackNeil Armstrong2024-10-141-1/+1
| | | | | | | | | | | | | | Add a new get_max_pwr_mode callback to permit the UFS controller driver manipulate the max_pwr_mode struct right before setting the new pwr_mode to the UFS device. It can be used to limit the HS Gear with errata and hardware limitations on some UFS controllers.

* ufs: core: remove link_startup_again logicNeil Armstrong2024-10-141-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ufs: Add missing memory barriersBhupesh Sharma2024-10-141-0/+11
| | | | | | | | | | | | | | | | | | | | Add missing wmb() and mb() barriers in the u-boot UFS core framework driver to allow registers updates to happen before follow-up read operations. This makes the barrier placement similar to the Linux UFS driver, synced from the Linux v6.9 release. Starting from the v6.10 release, the barriers were replaced with a register read-back in [1], this will ported to u-boot in a second time.

* ufs: split flush and invalidate to only invalidate when requiredNeil Armstrong2024-10-141-15/+30
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | The implementation of dma_map_single() and dma_unmap_single() is exactly the same for all the architectures that support them. Factor them out to <linux/dma-mapping.h>, and make all drivers to include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>. If we need to differentiate them for some architectures, we can move the generic definitions to <asm-generic/dma-mapping.h>. Add some comments to the helpers. The concept is quite similar to the DMA-API of Linux kernel. Drivers are agnostic about what is going on behind the scene. Just call dma_map_single() before the DMA, and dma_unmap_single() after it.
