Subject: [PATCH] ARM: tegra: Add core supply for Tegra114 boards
Date: Wed, 30 Sep 2026 13:11:40 +0900 [thread overview]
Message-ID: <20260930-dalmore-fixes-core-supply-v1-1-4bd87fd70b0d@nvidia.com> (raw)
After commit 4cc90d4c043e ("ARM: tegra: Configure Tegra114 power
domains"), a core-supply property is required in the PMC node.
Label the core regulator on Dalmore, NVIDIA SHIELD and Tegra Note 7
and add the property.
Fixes: 4cc90d4c043e ("ARM: tegra: Configure Tegra114 power domains")
Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com>

This skips TF701T since there is already a patch on the mailing list for
it. Tested on Dalmore, but not on TN7 or SHIELD Portable.
