ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mripard/linux into arm/drivers Allwinner MBUS and DMA-ops rework The Allwinner SoCs have a number of high-bandwidth devices connected to a memory bus with a different RAM mapping than the CPU. This was addressed before through drivers setting the DMA offsets directly, and subsequently changed to calls to dma_direct_set_offset. However that wasn't really meant to be exported to modules (and thus drivers). The duplicated code also led to small inconsistencies across drivers in how we dealt with DT backward compatibility. Move all that DMA setup code into a platform bus notifier to share that code and remove the export on dma_direct_set_offset. * tag 'sunxi-rework-mbus' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mripard/linux: dma-mapping: remove the dma_direct_set_offset export media: sun8i-di: Remove the call to of_dma_configure media: cedrus: Remove the MBUS quirks media: sun6i: Remove the MBUS quirks media: sun4i: Remove the MBUS quirks drm/sun4i: backend: Remove the MBUS quirks soc: sunxi: Deal with the MBUS DMA offsets in a central place drm/sun4i: backend: Fix probe failure with multiple backends Signed-off-by: Arnd Bergmann <[email protected]>

Add support for new SCMI v3.0 Sensors extensions related to new sensors' features, like multiple axis and update intervals, while keeping compatibility with SCMI v2.0 features. While at that, refactor and simplify all the internal helpers macros and move struct scmi_sensor_info to use only non-fixed-size typing.

2020-11-20firmware: arm_scmi: Add full list of sensor type enumerationSudeep Holla1-0/+81
SCMI v2.0 provides a big list of sensor type enumeration from the sensorUnits enumeration table of Distributed Management Task Force(DMTF) specification number DSP 0248 (Platform Level Data Model for Platform Monitoring and Control Specification). It is however not an exact replica of the sensorUnits enumeration table. Let us just update the table as per SCMI v2.0 specification.
