Merge tag 'samsung-drivers-exynos5440-4.19' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/drivers Exynos5440 drivers removal The Exynos5440 (quad-core A15 with GMAC, PCIe, SATA) was targeting server platforms but it did not make it to the market really. There are no development boards with it and probably there are no real products neither. The development for Exynos5440 ended in 2013 and since then the platform is in maintenance mode. Removing Exynos5440 makes our life slightly easier: less maintenance, smaller code, reduced number of quirks, no need to preserve DTB backward-compatibility. The Device Tree sources and some of the drivers for Exynos5440 were already removed. This removes remaining drivers. * tag 'samsung-drivers-exynos5440-4.19' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: usb: host: exynos: Remove support for Exynos5440 clk: samsung: Remove support for Exynos5440 cpufreq: exynos: Remove support for Exynos5440 ata: ahci-platform: Remove support for Exynos5440 Signed-off-by: Olof Johansson <olof@lixom.net>

Commit 7f9545aa ("arm64: smp: remove cpu and numa topology information when hotplugging out CPU") updates the cpu topology when the CPU is hotplugged out. However the PSCI checker code uses the topology_core_cpumask pointers for some of the cpu hotplug testing. Since the pointer to the core_cpumask of the first CPU in the group is used, which when that CPU itself is hotpugged out is just set to itself, the testing terminates after that particular CPU is tested out. But the intention of this tests is to cover all the CPU in the group. In order to support that, we need to stash the topology_core_cpumask before the start of the test and use that value instead of pointer to a cpumask which will be updated on CPU hotplug.

Some RSCs may only have sleep and wake TCS, i.e, there is no dedicated TCS for active mode request, but drivers may still want to make active requests from these RSCs. In such cases re-purpose the wake TCS to send active state requests. The requirement for this is that the driver is aware that the wake TCS is being repurposed to send active request, hence the sleep and wake TCSes be invalidated before the active request is sent.

Platform drivers need make a lot of resource state requests at the same time, say, at the start or end of an usecase. It can be quite inefficient to send each request separately. Instead they can give the RPMH library a batch of requests to be sent and wait on the whole transaction to be complete. rpmh_write_batch() is a blocking call that can be used to send multiple RPMH command sets. Each RPMH command set is set asynchronously and the API blocks until all the command sets are complete and receive their tx_done callbacks.

Platform drivers that want to send a request but do not want to block until the RPMH request completes have now a new API - rpmh_write_async(). The API allocates memory and send the requests and returns the control back to the platform driver. The tx_done callback from the controller is handled in the context of the controller's thread and frees the allocated memory. This API allows RPMH requests from atomic contexts as well.

Active state requests are sent immediately to the RSC controller, while sleep and wake state requests are cached in this driver to avoid taxing the RSC controller repeatedly. The cached values will be sent to the controller when the rpmh_flush() is called. Generally, flushing is a system PM activity and may be called from the system PM drivers when the system is entering suspend or deeper sleep modes during cpuidle. Also allow invalidating the cached requests, so they may be re-populated again.

Sleep and wake requests are sent when the application processor subsystem of the SoC is entering deep sleep states like in suspend. These requests help lower the system power requirements when the resources are not in use. Sleep and wake requests are written to the TCS slots but are not triggered at the time of writing. The TCS are triggered by the firmware after the last of the CPUs has executed its WFI. Since these requests may come in different batches of requests, it is the job of this controller driver to find and arrange the requests into the available TCSes.

Add controller driver for QCOM SoCs that have hardware based shared resource management. The hardware IP known as RSC (Resource State Coordinator) houses multiple Direct Resource Voter (DRV) for different execution levels. A DRV is a unique voter on the state of a shared resource. A Trigger Control Set (TCS) is a bunch of slots that can house multiple resource state requests, that when triggered will issue those requests through an internal bus to the Resource Power Manager Hardened (RPMH) blocks. These hardware blocks are capable of adjusting clocks, voltages, etc. The resource state request from a DRV are aggregated along with state requests from other processors in the SoC and the aggregate value is applied on the resource. Some important aspects of the RPMH communication - - Requests are <addr, value> with some header information - Multiple requests (upto 16) may be sent through a TCS, at a time - Requests in a TCS are sent in sequence - Requests may be fire-n-forget or completion (response expected) - Multiple TCS from the same DRV may be triggered simultaneously - Cannot send a request if another request for the same addr is in progress from the same DRV - When all the requests from a TCS are complete, an IRQ is raised - The IRQ handler needs to clear the TCS before it is available for reuse - TCS configuration is specific to a DRV - Platform drivers may use DRV from different RSCs to make requests Resource state requests made when CPUs are active are called 'active' state requests. Requests made when all the CPUs are powered down (idle state) are called 'sleep' state requests. They are matched by a corresponding 'wake' state requests which puts the resources back in to previously requested active state before resuming any CPU. TCSes are dedicated for each type of requests. Active mode TCSes (AMC) are used to send requests immediately to the resource, while control TCS are used to provide specific information to the controller. Sleep and Wake TCS send sleep and wake requests, after and before the system halt respectively.

This is functionally identical but simpler and slightly faster. The PU domain is turned on at boot time and never turned off. In the current implementation the pm core will repeatedly call power_off when the domain is unused and get -EBUSY back. If the domain is marked as "always on" instead the pm core won't even attempt to turn it off. In theory on 6qp it is safe to turn PU off in suspend, however that is best accomplished with a new core flag.
