soc: tegra: Simplify with of_machine_device_match()

2025-11-27T01:43:12+00:00

Replace open-coded getting root OF node and matching against it with new of_machine_device_match() helper.

soc/tegra: Migrate to dev_pm_opp_set_config()

2022-07-08T05:57:33+00:00

The OPP core now provides a unified API for setting all configuration types, i.e. dev_pm_opp_set_config(). Lets start using it. Tested-by: Dmitry Osipenko Signed-off-by: Viresh Kumar

soc/tegra: Add comment over devm_pm_opp_set_clkname()

2022-07-08T05:57:33+00:00

Explain why special handling was required here, it isn't obvious at all. Tested-by: Dmitry Osipenko Signed-off-by: Viresh Kumar

soc/tegra: Don't print error message when OPPs not available

2021-12-16T13:03:38+00:00

Previously we assumed that devm_tegra_core_dev_init_opp_table() will be used only by drivers that will always have device with OPP table, but this is not true anymore. For example now Tegra30 will have OPP table for PWM, but Tegra20 not and both use the same driver. Hence let's not print the error message about missing OPP table in the common helper, we can print it elsewhere. Reviewed-by: Ulf Hansson Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

soc/tegra: Enable runtime PM during OPP state-syncing

2021-12-16T13:03:38+00:00

GENPD core now can set up domain's performance state properly while device is RPM-suspended. Runtime PM of a device must be enabled during setup because GENPD checks whether device is suspended and check doesn't work while RPM is disabled. Instead of replicating the boilerplate RPM-enable code around OPP helper for each driver, let's make OPP helper to take care of enabling it.

soc/tegra: Don't leak device tree node reference

2018-11-22T15:10:04+00:00

of_find_node_by_path() acquires a reference to the node returned by it and that reference needs to be dropped by its caller. soc_is_tegra() doesn't do that, so fix it.
