[PATCH 2/4] soc: qcom: llcc-qcom: Add support for LLCC V6

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

 



Add support for LLCC V6. V6 adds several additional usecase IDs,
rearrages several registers and offsets, and supports slice IDs
over 31, so add a new function for programming LLCC V6.
