From: Svyatoslav Ryhel Date: Thu, 16 Nov 2023 07:35:26 +0000 (+0200) Subject: ARM: tegra114: clock: implement PLLD2 support X-Git-Url: http://git.dujemihanovic.xyz/html/%7B%7B%20%28.OutputFormats.Get?a=commitdiff_plain;h=944ac34075fe1dd1a16f0dee0d7279c8d49a537a;p=u-boot.git ARM: tegra114: clock: implement PLLD2 support PLLD2 is a simple clock (controlled by 2 registers) and appears starting from T30. Primary use of PLLD2 is as main HDMI clock parent.
