ufs: amd-versal2: Remove ZYNQMP_FIRMWARE dependency

2026-08-12T04:55:15Z

There are EEMI firmware hooks available but they are also IO versions of it that's why remove ZYNQMP_FIRMWARE depency from UFS driver. Signed-off-by: Michal Simek Link: https://patch.msgid.link/85cbacdc7492890c76396974d24fff607c2088ad.1785394153.git.michal.simek@amd.com

xilinx: versal2: Clean UFS firmware interface

2026-08-12T04:55:15Z

The M-PHY and SRAM readiness poll loops move out of the UFS controller driver and into the firmware backend, exposed as blocking waits with a caller-owned timeout budget. This keeps the UFS driver backend-agnostic and lets an other backends offload the wait to the platform in a single call instead of round-tripping every poll. set_sram_bypass() now performs the SRAM_CSR read-modify-write in the firmware layer. Hook up functions are also update to reflect their usage. Signed-off-by: Michal Simek Link: https://patch.msgid.link/26bc9aa2c02921690e126ab3401f7974ef04ad6e.1785394153.git.michal.simek@amd.com

ufs: amd-versal2: Perform controller reset in the init callback

2026-08-12T04:55:14Z

Move the controller/PHY reset and SRAM-bypass sequence from hce_enable_notify(PRE_CHANGE) into ufs_versal2_init(). The reset sequence releases the host controller from reset, and the UFS core reads the capability and version registers right after .init() and before ufshcd_hba_enable() (the only caller of hce_enable_notify()). Doing the reset in .init() ensures those registers are read after the controller is out of reset, and keeps the driver aligned with Linux. ufs_versal2_phy_init() stays in POST_CHANGE.

ufs: invalidate the whole descriptor data segment after a query read

2026-07-21T07:22:58Z

ufshcd_get_req_rsp() invalidates only sizeof(struct utp_upiu_rsp) of the DMA'd response, but a READ DESCRIPTOR response's data segment follows the UPIU header at GENERAL_UPIU_REQUEST_SIZE and can extend past that window. The tail of a longer descriptor was therefore read from stale cache (the pre-transfer memset had zeroed it), so its last bytes came back as 0. This corrupted the last UTF-16 code unit of longer string descriptors: e.g. a 34-byte product-name descriptor "THGJFGT0T25BAZZA" was read as "THGJFGT0T25BAZZ\0", dropping the final 'A'. Shorter descriptors that fit within the invalidated cache line (serial numbers, etc.) were unaffected. Invalidate the descriptor region before copying it out. Tested on the Qualcomm IQ-9075-EVK.

treewide: Kconfig: use bool instead of tristate

2026-07-10T21:45:57Z

U-Boot does not support modules, so having tristate options is useless. Therefore this patch does a blind replace of all tristate options to bool tree-wide.

ufs: amd-versal2: Fix missing .priv_auto in driver registration

2026-07-08T06:55:51Z

Add missing .priv_auto field to the driver. Without it, struct ufs_versal2_priv is never properly allocated and dev_get_priv() returns NULL, leading to DDR corruption at low DDR addresses.

ufs: qcom: Remove redundant POST_CHANGE clock setup call

2026-05-18T09:04:14Z

The ufs_qcom_init() function was calling ufs_qcom_setup_clocks() with POST_CHANGE twice. The first call after setting PA_TXHSADAPTTYPE correctly enables the device reference clock. The second call after ufs_qcom_advertise_quirks() is redundant as the clock is already enabled.
