2020-03-13soc/tegra: Add support for 32 kHz blink clockSowjanya Komatineni1-0/+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.

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.

2020-02-27soc: ti: pm33xx: Add base cpuidle supportDave Gerlach1-1/+20
Some cpuidle C-states supported on am335x and am437x, like C1 on am335x, require the use of the wkup_m3_ipc driver, and all C-states beyond C0 on both platforms require the use of the SRAM sleep code. Pass am33xx_do_sram_idle as the idle function to the platform pm core to be used by the cpuidle-arm driver when entering cpuidle states. am33xx_do_sram_idle will detect when the wkup_m3 is needed and ping it if necessary before calling the final cpu_suspend op which will execute the SRAM code to put the cpu into idle. Finally, use the begin_suspend and finish_suspend platform ops to be called at the beginning and end of suspend path to allow use of cpu_idle_poll_ctrl. This prevents races between cpuidle and suspend paths trying to communicate with the wkup_m3, as during suspend we only want it configured for entry to suspend.

In order for am335x and am437x to properly enter deeper c-states in cpuidle they must always call into the sleep33/43xx suspend code and also sometimes invoke the wkup_m3_ipc driver. These are both controlled by the pm33xx module so we must provide a method for the platform code to call back into the module when it is available as the core cpuidle ops that are invoked by the cpuidle-arm driver must remain as built in. Extend the init platform op to take an idle function as an argument so that we can use this to call into the pm33xx module for c-states that need it. Also add a deinit op so we can unregister this idle function from the PM core when the pm33xx module gets unloaded.

2020-02-24soc: imx-scu: Align imx sc msg structs to 4Leonard Crestez1-1/+1
The imx SC api strongly assumes that messages are composed out of 4-bytes words but some of our message structs have odd sizeofs. This produces many oopses with CONFIG_KASAN=y. Fix by marking with __aligned(4).

In some device memory used by msm_qmp, there can be an early ack of a write to memory succeeding. This may cause the outgoing interrupt to be triggered before the msgram reflects the write. Add a readback to ensure the data is flushed to device memory before triggering the ipc interrupt.
