Subject: [PATCH v1 0/2] Fix Tegra PMC driver racing with cpuidle driver
Date: Mon, 19 Jul 2021 00:27:04 +0300 [thread overview]
Message-ID: <20210718212706.21659-1-digetx@gmail.com> (raw)
I stumbled upon a problem where tegra-cpuidle driver is probed before
Power Management controller driver in a specific kernel configuration,
implicitly disabling the deepest CPU idling state. This series fixes
that trouble.
