Subject: [PATCH 13/14] clk: tegra: Correct Tegra210 UTMIPLL poweron delay
Date: Tue, 25 Jul 2017 13:34:14 +0300 [thread overview]
Message-ID: <1500978856-5981-14-git-send-email-pdeschrijver@nvidia.com> (raw)
In-Reply-To: <1500978856-5981-1-git-send-email-pdeschrijver@nvidia.com>
From: Alex Frid <afrid@nvidia.com>
Increased Tegra210 UTMIPLL power on delay to 20us (spec maximum is 15us).
Also remove a few empty lines to make it more clear the ACTIVE_DLY_COUNT
and ENABLE_DLY_COUNT fields.
