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.

2020-03-13soc/tegra: Add support for 32 kHz blink clockGravatar Sowjanya Komatineni 1-0/+112
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.

2020-03-13soc/tegra: Add Tegra PMC clocks registration into PMC driverGravatar Sowjanya Komatineni 1-0/+242
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.

2019-10-29soc/tegra: pmc: Remove unnecessary memory barrierGravatar Dmitry Osipenko 1-2/+0
The removed barrier isn't needed because writes/reads are strictly ordered and even if PMC had separate ports for writes, it wouldn't matter since the hardware logic takes into effect after triggering CPU's power-gating and at that point all CPU accesses are guaranteed to be completed. That barrier was copied from the old arch/ code during transition to the soc/ PMC driver and even that the code structure was different back then, the barrier didn't have a real useful purpose from the start. Lastly, the tegra_pmc_writel() naturally inserts wmb() because it uses writel(), and thus this change doesn't actually make any difference in terms of interacting with hardware. Hence let's remove the barrier to clean up code a tad. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>

The TRM doc states that WFI should be used for the Big-Little "Cluster Switch", while WFE for the power-gating. Hence let's use the WFE for CPU0 power-gating, like it is done for the power-gating of a secondary cores. This fixes CPU hang after entering LP2 with memory running off PLLP.

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.

Tegra210 and prior Tegra chips have deep sleep entry and wakeup related timings which are platform specific that should be configured before entering into deep sleep. Below are the timing specific configurations for deep sleep entry and wakeup. - Core rail power-on stabilization timer - OSC clock stabilization timer after SOC rail power is stabilized. - Core power off time is the minimum wake delay to keep the system in deep sleep state irrespective of any quick wake event. These values depends on the discharge time of regulators and turn OFF time of the PMIC to allow the complete system to finish entering into deep sleep state. These values vary based on the platform design and are specified through the device tree.

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.
