[RFC 3/7] drm/amd/display: Add FPU file for functions shared across ASICs
Rodrigo Siqueira

Mon Jan 25 13:43:09 UTC 2021
In our DC code, we have a couple of functions that use FPU and are
shared between multiples ASICs; this situation complicates the work of
centralizing FPU functions in a single place. This commit tries to
alleviate this problem by creating a file named fpu_commons to
centralize shared functions that use FPU operation in a single file. As
a start point, we move dcn20_calculate_dlg_params to this file.
