Which names to associate with nodes in the device tree for UFS MCQ
resources has not been standardized. Additionally, the UFS driver is
also used on platforms that do not support the device tree (e.g. Intel
x86 platforms). So I don't think that the platform_get_resource_byname()
calls should occur in the UFS driver core. How about moving the code
that queries device tree nodes into the Qualcomm driver until a second
user of this code is added? If a second user of this code appears this
code could e.g. become a kernel module shared by both UFS host
controller drivers.
Thanks,
