From: Anthony Koo Date: Wed, 22 Apr 2020 02:01:30 +0000 (-0400) Subject: drm/amd/display: add addition dc type to translate to dmub fw type X-Git-Tag: baikal/mips/sdk5.9~13559^2~11^2~44 X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=bc4b5dd3bdb073ae5ab80343bea20b725b2d4546;p=kernel.git drm/amd/display: add addition dc type to translate to dmub fw type [Why] For a type like PSR version, it makes sense for most of the code to include a dc type, instead of having this a fw type define since this is a capability and type exposed by dc. Especially if it doesn't even need to communicate with the fw. The code that is packing the firmware command message should be the one who needs to translate the psr version into a command that the firmware understands. [How] Add a dc_psr_version enum.
