The UFS_RESET pin on Qualcomm SoCs are controlled by TLMM and exposed through the GPIO framework. Acquire the device-reset GPIO and use this to implement the device_reset vops, to allow resetting the attached memory. Based on downstream support implemented by Subhash Jadavani <subhashj@codeaurora.org>.

2019-02-08scsi: dt-bindings: ufs: Fix the compatible string definitionDouglas Anderson1-5/+8
If you look at the bindings for the UFS Host Controller it says: - compatible: must contain "jedec,ufs-1.1" or "jedec,ufs-2.0", may also list one or more of the following: "qcom,msm8994-ufshc" "qcom,msm8996-ufshc" "qcom,ufshc" My reading of that is that it's fine to just have either of these: 1. "qcom,msm8996-ufshc", "jedec,ufs-2.0" 2. "qcom,ufshc", "jedec,ufs-2.0" As far as I can tell neither of the above is actually a good idea. For #1 it turns out that the driver currently only keys off the compatible string "qcom,ufshc" so it won't actually probe. For #2 the driver won't probe but it's not a good idea to keep the SoC name out of the compatible string. Let's update the compatible string to make it really explicit. We'll include a nod to the existing driver and the old binding and say that we should always include the "qcom,ufshc" string in addition to the SoC compatible string. While we're at it we'll also include another example SoC known to have UFS: sdm845.

UFS host supplies the reference clock to UFS device and UFS device specification allows host to provide one of the 4 frequencies (19.2 MHz, 26 MHz, 38.4 MHz, 52 MHz) for reference clock. Host should set the device reference clock frequency setting in the device based on what frequency it is supplying to UFS device.

2015-11-09scsi: ufs: make the UFS variant a platform deviceYaniv Gardi1-1/+10
This change turns the UFS variant (SCSI_UFS_QCOM) into a UFS a platform device. In order to do so a few additional changes are required: 1. The ufshcd-pltfrm is no longer serves as a platform device. Now it only serves as a group of platform APIs such as PM APIs (runtime suspend/resume, system suspend/resume etc), parsers of clocks, regulators and pm_levels from DT. 2. What used to be the old platform "probe" is now "only" a pltfrm_init() routine, that does exactly the same, but only being called by the new probe function of the UFS variant.
