Subject: [RFC PATCH v2 2/2] arm64: dts: rockchip: drop PCIe 3v3 always-on and boot-on
Date: Tue, 10 Jun 2025 13:37:29 -0300 [thread overview]
Message-ID: <28fb85b76b3adba86995b187036f3eff8a68e10e.1749572238.git.geraldogabriel@gmail.com> (raw)
In-Reply-To: <cover.1749572238.git.geraldogabriel@gmail.com>
Example commit of needed dropping of regulator always-on/boot-on
declarations to make sure quirky devices known to not be working
on RK3399 are able to enumerate on second try without
assertion/deassertion of PERST# in-band PCIe reset signal.
One example only, to avoid patch-bomb.
