Subject: [PATCH V5 01/27] soc/tegra: pmc: Export tegra_powergate_power_on()
Date: Mon, 17 Jun 2019 23:09:26 +0530 [thread overview]
Message-ID: <20190617173952.29363-2-mmaddireddy@nvidia.com> (raw)
In-Reply-To: <20190617173952.29363-1-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.
