2021-03-30firmware: arm_scmi: Add dynamic scmi devices creationCristian Marussi3-34/+311
Having added the support for SCMI protocols as modules in order to let vendors extend the SCMI core with their own additions it seems odd to then force SCMI drivers built on top to use a static device table to declare their devices since this way any new SCMI drivers addition would need the core SCMI device table to be updated too. Remove the static core device table and let SCMI drivers to simply declare which device/protocol pair they need at initialization time: the core will then take care to generate such devices dynamically during platform initialization or at module loading time, as long as the requested underlying protocol is defined in the devicetree.

2021-03-30perf/arm_pmu_platform: Clean up with dev_printkRobin Murphy1-25/+22
Nearly all of the messages we can log from the platform device code relate to the specific PMU device and the properties we're parsing from its DT node. In some cases we use %pOF to point at where something was wrong, but even that is inconsistent. Let's convert these logs to the appropriate dev_printk variants, so that every issue specific to the device and/or its DT description is clearly and instantly attributable, particularly if there is more than one PMU node present in the DT. The local refactoring in a couple of functions invites some extra cleanup in the process - the init_fn matching can be streamlined, and the PMU registration failure message moved to the appropriate place and log level.

Resetting the IP core will lose the bus width information and not all code paths recover it. So, make sure the latest bus width gets restored in the reset routine. For that, tmio_mmc_set_bus_width() is moved, but not modified.

2021-03-30mmc: sdhci-acpi: Add device ID for the AMDI0041 variant of the AMD eMMC controller.James Young1-0/+2
This variant is present on a Lenovo IdeaPad Slim 1, which uses an AMD Dali/Athlon Silver 3050e. The Windows AMD SD Host Controller driver also lists this as a valid device ID. Adding this device ID makes the internal eMMC storage on the Lenovo accessible. Consequently this makes Linux installable and usable on it as well.

2021-03-30mmc: renesas_sdhi: do hard reset if possibleWolfram Sang3-1/+19
All recent SDHI instances can be reset via the reset controller. If one is found, use it instead of the open coded reset. This is to get a future-proof sane reset state.

renesas_sdhi_reset used to mainly reset the SCC but is now doing more and even more will be added. So, factor out SCC reset to have a clear distinction when we want to reset either SCC or SDHI+SCC.

2021-03-30mmc: tmio: abort DMA before resetWolfram Sang1-2/+2
We will soon allow resetting the whole IP core via a reset controller. For this case, DMA must be terminated before the actual reset. For the other cases, it is probably better, too.
