[PATCH V1] Power Class Selection Feature

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch version modifies the power_class_select function prototype.

During device enumeration, when the host tries to read the extended
csd register after switching to higher bus width, the read fails at
higher bus width. So the power_class_select function is modified to
reuse the extended csd register values read with 1 bit bus width.
