soc/tegra: pmc: Enable PMIC wake event on Tegra210

2020-05-22T12:55:54Z

The PMIC wake event can be used to bring the system out of suspend based on certain events happening on the PMIC (such as an RTC alarm). Signed-off-by: Jon Hunter Signed-off-by: Thierry Reding

soc/tegra: pmc: Add pins for Tegra194

2020-03-13T09:53:10Z

Extend the Tegra194 IO pad table with additional information such as pin names and 1.8/3.3 V settings to allow a table of voltage control pins to generated from it. This is similar to what's done for older chips and is needed to support high-speed modes for SDHCI where switching the pins to 1.8V or 3.3V is necessary.

soc/tegra: Add support for 32 kHz blink clock

2020-03-13T09:53:06Z

Tegra PMC has blink control to output 32 kHz clock out to Tegra blink pin. Blink pad DPD state and enable controls are part of Tegra PMC register space. Currently Tegra clock driver registers blink control by passing PMC address and register offset to clk_register_gate which performs direct PMC access during clk_ops and with this when PMC is in secure mode, any access from non-secure world does not go through. This patch adds blink control registration to the Tegra PMC driver using PMC specific clock gate operations that use tegra_pmc_readl() and tegra_pmc_writel() to support both secure mode and non-secure mode PMC register access.

soc/tegra: Add Tegra PMC clocks registration into PMC driver

2020-03-13T09:52:53Z

Tegra PMC has clk_out_1, clk_out_2, and clk_out_3 clocks and currently these PMC clocks are registered by Tegra clock driver with each clock as separate mux and gate clocks using clk_register_mux and clk_register_gate by passing PMC base address and register offsets and PMC programming for these clocks happens through direct PMC access by the clock driver. With this, when PMC is in secure mode any direct PMC access from the non-secure world does not go through and these clocks will not be functional. This patch adds these PMC clocks registration to pmc driver with PMC as a clock provider and registers each clock as single clock. clk_ops callback implementations for these clocks uses tegra_pmc_readl and tegra_pmc_writel which supports PMC programming in both secure mode and non-secure mode.

soc/tegra: pmc: Add reset sources and levels on Tegra194

2019-11-18T12:56:58Z

Tegra194 supports the same reset levels as Tegra186 but extends the set of reset sources. Provide custom PMC register definitions to account for the larger field for the reset sources as well as the updated list of reset sources. Signed-off-by: Thierry Reding --- Changes in v2: - use the new Tegra194 register definitions

soc/tegra: pmc: Add missing IRQ callbacks on Tegra194

2019-11-18T12:55:56Z

Reuse the IRQ callbacks from Tegra186 on Tegra194. This fixes failures to request interrupts on Tegra194 due to the missing callbacks.
