scsi: ufs: ufs-qcom: Switch to the new ICE API Now that there is a new dedicated ICE driver, drop the ufs-qcom-ice and use the new ICE api provided by the Qualcomm soc driver ice. The platforms that already have ICE support will use the API as library since there will not be a devicetree node, but instead they have reg range. In this case, the of_qcom_ice_get will return an ICE instance created for the consumer's device. But if there are platforms that do not have ice reg in the consumer devicetree node and instead provide a dedicated ICE devicetree node, the of_qcom_ice_get will look up the device based on qcom,ice property and will get the ICE instance registered by the probe function of the ice driver. The ICE clock is now handle by the new driver. This is done by enabling it on the creation of the ICE instance and then enabling/disabling it on UFS runtime resume/suspend.

scsi: ufs: cdns-pltfrm: Perform read back after writing HCLKDIV stable inclusion from stable-6.6.33 commit 872f68019bc6b91d6ae97394dc7f8a686b7106c2 category: bugfix issue: #IB7W7N CVE: NA Signed-off-by: zhangshuqi <zhangshuqi3@huawei.com> --------------------------------------- [ Upstream commit b715c55daf598aac8fa339048e4ca8a0916b332e ] Currently, HCLKDIV is written to and then completed with an mb(). mb() ensures that the write completes, but completion doesn't mean that it isn't stored in a buffer somewhere. The recommendation for ensuring this bit has taken effect on the device is to perform a read back to force it to make it all the way to the device. This is documented in device-io.rst and a talk by Will Deacon on this can be seen over here: https://youtu.be/i6DayghhA8Q?si=MiyxB5cKJXSaoc01&t=1678 Let's do that to ensure the bit hits the device. Because the mb()'s purpose wasn't to add extra ordering (on top of the ordering guaranteed by writel()/readl()), it can safely be removed.

scsi: ufs: exynos: Fix programming of HCI_UTRL_NEXUS_TYPE stable inclusion from stable-6.6.105 commit 01aad16c2257 category: bugfix issue: #223 CVE: CVE-2025-39788 Signed-off-by: zxl <1554188414@qq.com> ------------------------------- scsi: ufs: exynos: Fix programming of HCI_UTRL_NEXUS_TYPE On Google gs101, the number of UTP transfer request slots (nutrs) is 32, and in this case the driver ends up programming the UTRL_NEXUS_TYPE incorrectly as 0. This is because the left hand side of the shift is 1, which is of type int, i.e. 31 bits wide. Shifting by more than that width results in undefined behaviour. Fix this by switching to the BIT() macro, which applies correct type casting as required. This ensures the correct value is written to UTRL_NEXUS_TYPE (0xffffffff on gs101), and it also fixes a UBSAN shift warning: UBSAN: shift-out-of-bounds in drivers/ufs/host/ufs-exynos.c:1113:21 shift exponent 32 is too large for 32-bit type 'int' For consistency, apply the same change to the nutmrs / UTMRL_NEXUS_TYPE write.
