2022-11-09soc: qcom: rpmh-rsc: Write CONTROL_TCS with next timer wakeupMaulik Shah3-1/+67
The next wakeup timer value needs to be set in always on domain timer as the arch timer interrupt can not wakeup the SoC if after the deepest CPUidle states the SoC also enters deepest low power state. To wakeup the SoC in such scenarios the earliest wakeup time is set in CONTROL_TCS and the firmware takes care of setting up its own timer in always on domain with next wakeup time. The timer wakes up the RSC and sets resources back to wake state.

2022-11-09PM: domains: Store the next hrtimer wakeup in genpdMaulik Shah3-0/+36
The arch timer cannot wake up the Qualcomm Technologies, Inc. (QTI) SoCs from the deeper CPUidle states. To be able to wakeup from these deeper states, another always-on timer needs to be programmed through the so called CONTROL_TCS. As the RSC is part of CPU subsystem and the corresponding APSS RSC device is attached to the cluster PM domain (through genpd), it holds the responsibility to program the always-on timer, before entering any of these deeper CPUidle states. However, programming the timer requires information about the next hrtimer wakeup for the cluster PM domain, which is currently only known by genpd. Therefore, let's share this data through a new genpd helper function, dev_pm_genpd_get_next_hrtimer(). Signed-off-by: Maulik Shah <quic_mkshah@quicinc.com> Cc: "Rafael J.

2022-11-09soc: qcom: rpmh-rsc: Attach RSC to cluster PM domainLina Iyer2-5/+66
RSC is part the CPU subsystem and powers off the CPU domains when all the CPUs and no RPMH transactions are pending from any of the drivers. The RSC needs to flush the 'sleep' and 'wake' votes that are critical for saving power when all the CPUs are in idle. Let's make RSC part of the CPU PM domains, by attaching it to the cluster power domain. Registering for PM domain notifications, RSC driver can be notified that the last CPU is powering down. When the last CPU is powering down the domain, let's flush the 'sleep' and 'wake' votes that are stored in the data buffers into the hardware and also write next wakeup in CONTROL_TCS.

Document the compatible for Qualcomm SM6375 SCM. SCM consumes a single clock (core / RPM_SMD_CE1_CLK), though it does not matter whether Linux enables it, as one of the billion levels of firmware ensures it's on anyway. Still, mark it as used for the sake of correctness.

This driver purely exposes information from memory to the kernel. Let's mark it as not having any device PM functionality, so that during suspend we skip even trying to call a suspend function on this device. This clears up suspend logs more than anything else, but it also shaves a few cycles off suspend.

2022-10-17soc: qcom: rpmhpd: Use highest corner until sync_stateBjorn Andersson1-1/+38
In some cases the hardware that the bootloader has left configured depends on RPMH power domains for their operation up until the point where the related Linux device driver probes and can inherit that configuration, or power down the hardware gracefully. Unfortunately as Linux probes the releavant drivers in sequence there are periods during the Linux boot flow where either the genpd refcount will reach 0, or worse where the active performance_state votes does not meet the requirements of the state that the hardware was left in. One specific example of this is during boot of e.g. SM8150/SC8180X, where the display clock controller probes, without any particular performance state needs (to access its registers). This will drop the MMCX rail to MIN_SVS, which isn't sufficient to sustain the clock rates that the later probing MDP is configured to. This results in an unrecoverable system state. Handle both these cases by keeping the RPMH power-domais that are referenced voted for highest state, until sync_state indicates that all devices referencing the RPMH power-domain driver has been probed.
