2021-08-10soc: ti: Remove pm_runtime_irq_safe() usage for smartreflexTony Lindgren
For the smartreflex device, we need to disable smartreflex on SoC idle, and have been using pm_runtime_irq_safe() to do that. But we want to remove the irq_safe usage as PM runtime takes a permanent usage count on the parent device with it. In order to remove the need for pm_runtime_irq_safe(), let's gate the clock directly in the driver. This removes the need to call PM runtime during idle, and allows us to switch to using CPU_PM in the following patch. Note that the smartreflex interconnect target module is configured for smart idle, but the clock does not have autoidle capability, and needs to be gated manually. If the clock supported autoidle, we would not need to even gate the clock. With this change, we can now remove the related quirk flags for ti-sysc also.

Set the BHI and/or BHIe offsets in mhi_prepare_for_power_up(), rearrange the function, and remove the equivalent from mhi_async_power_up(). This helps consolidate multiple checks in different parts of the driver and can help MHI fail early on before power up begins if the offsets are not read correctly.

2021-08-05bus: mhi: Add inbound buffers allocation flagLoic Poulain
Currently, the MHI controller driver defines which channels should have their inbound buffers allocated and queued. But ideally, this is something that should be decided by the MHI device driver instead, which actually deals with that buffers. Add a flag parameter to mhi_prepare_for_transfer allowing to specify if buffers have to be allocated and queued by the MHI stack. Keep auto_queue flag for now, but should be removed at some point.

The Intel IXP4xx SoCs have an expansion bus that is usually just used for flash memory and configured by the boot loaders and can be accessed using the "simple-bus". However some devices need more elaborate configuration and then we need to provide a proper 3-unit address space indicating chip select for each device and provide timing and similar information.

Some versions of the MC firmware wrongly report 0 for register base address of the DPMCP associated with child DPRC objects thus rendering them unusable. This is particularly troublesome in ACPI boot scenarios where the legacy way of extracting this base address from the device tree does not apply.
