[PATCH v3 2/3] scsi: ufs-qcom: Implement device_reset vops

2019-06-07 Thread Bjorn Andersson
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 . Signed-off-by: Bjo
