Subject: [PATCH V3 06/19] clk: tegra: remove TEGRA_PLL_USE_LOCK for PLLD/PLLD2
Date: Mon, 13 Jul 2015 13:39:44 +0100 [thread overview]
Message-ID: <1436791197-32358-7-git-send-email-jonathanh@nvidia.com> (raw)
In-Reply-To: <1436791197-32358-1-git-send-email-jonathanh@nvidia.com>
From: Vince Hsu <vinceh@nvidia.com>
Tegra114 has a HW bug that the PLLD/PLLD2 lock bit cannot be asserted when
the DIS power domain is during up-powergating process but the clamp to this
domain is not removed yet. That causes a timeout and aborts the power
sequence, although the PLLD/PLLD2 has already locked. To remove the false
alarm, we don't use the lock for PLLD/PLLD2. Just wait 1ms and treat the
clocks as locked.
