Subject: drm/amd/display: Add DRAM table fields to clk_mgr_internal
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ee87d401f54a732d654192a6f48b39a8fc1f25ca;p=thirdparty%2Flinux.git

drm/amd/display: Add DRAM table fields to clk_mgr_internal

[Why]
Add GPU-accessible DRAM buffer fields for bulk data
transfer from PMFW during clock manager initialization.

[How]
Add dal_init_table and dal_init_table_addr fields to
struct clk_mgr_internal for TABLE_DAL_INIT DRAM transfer.
