Subject: [PATCH V2 01/28] soc/tegra: pmc: Export tegra_powergate_power_on()
Date: Tue, 23 Apr 2019 14:57:58 +0530 [thread overview]
Message-ID: <20190423092825.759-2-mmaddireddy@nvidia.com> (raw)
In-Reply-To: <20190423092825.759-1-mmaddireddy@nvidia.com>
tegra_powergate_sequence_power_up() powers up partition and also enables
clock & reset. However, if a controller like PCIe have multiple clocks
& resets and they need to be enabled in a sequence, driver must use
standalone function tegra_powergate_power_on() to power up partition.
Export tegra_powergate_power_on() to allow Tegra controller drivers to
unpower gate partition independent to clock & reset.
