X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=cabd44c064c84064292508a58c97f4e9ad9a6409;p=openwrt%2Fstaging%2Fblogic.git

drm/amd/powerplay: add interface to init smc tables (v2)

This patch adds interface to init smc tables for smu. It is to create smu_table
structure, and init smc tables such as TABLE_PPTABLE, TABLE_WATERMARKS,
TABLE_SMU_METRICS, and etc.

v2: add detailed info to describe this function
