soc/tegra: pmc: Select REGMAP

2022-05-04T09:09:49Z

Commit 9d5e7c3e36eb ("soc/tegra: pmc: Provide USB sleepwalk register map") introduced a dependency on the regmap infrastructure, so select the corresponding Kconfig entry. This avoids failures in random builds that may otherwise end up having SOC_TEGRA_PMC enabled but not REGMAP. Signed-off-by: Thierry Reding

soc/tegra: Make regulator couplers depend on CONFIG_REGULATOR

2021-08-02T12:30:46Z

The regulator coupler drivers now use regulator-driver API function that isn't available during compile-testing. Make regulator coupler drivers dependent on CONFIG_REGULATOR in Kconfig.

soc/tegra: pmc: Add core power domain

2021-06-02T08:58:42Z

NVIDIA Tegra SoCs have multiple power domains, each domain corresponds to an external SoC power rail. Core power domain covers vast majority of hardware blocks within a Tegra SoC. The voltage of a power domain should be set to a level which satisfies all devices within the power domain. Add support for the core power domain which controls voltage state of the domain. This allows us to support system-wide DVFS on Tegra20-210 SoCs. The PMC powergate domains now are sub-domains of the core domain, this requires device-tree updating, older DTBs are unaffected and will continue to work as before.

arm64: tegra: Initial Tegra234 VDK support

2020-09-18T13:58:07Z

The NVIDIA Tegra234 VDK is a simulation platform for the Orin SoC. It supports a subset of the peripherals that will be available in the final chip and serves as a bootstrapping platform. Reviewed-by: Jon Hunter Signed-off-by: Thierry Reding

soc/tegra: pmc: Select GENERIC_PINCONF

soc/tegra: regulators: Add regulators coupler for Tegra30

2019-10-29T13:02:59Z

Add regulators coupler for Tegra30 SoCs that performs voltage balancing of a coupled regulators and thus provides voltage scaling functionality. There are 2 coupled regulators on all Tegra30 SoCs: CORE and CPU. The coupled regulator voltages shall be in a range of 300mV from each other and CORE voltage shall be higher than the CPU by N mV, where N depends on the CPU voltage.

soc/tegra: regulators: Add regulators coupler for Tegra20

2019-10-29T13:02:59Z

Add regulators coupler for Tegra20 SoCs that performs voltage balancing of a coupled regulators and thus provides voltage scaling functionality. There are 3 coupled regulators on all Tegra20 SoCs: CORE, RTC and CPU. The CORE and RTC voltages shall be in range of 170mV from each other and they both shall be higher than the CPU voltage by at least 120mV. This sounds like it could be handle by a generic voltage balancer, but the CORE voltage scaling isn't implemented in any of the upstream drivers yet. It will take quite some time and effort to hook up voltage scaling for all of the drivers, hence we will use a custom coupler that will manage the CPU voltage scaling for the starter.
