interconnect: qcom: rpm: Use _optional func for provider clocks

2023-01-05T15:29:57Z

It turned out that - very unfortunately - msm8996 needs a binding update, adding 2 more clocks to the A2NoC node. Use the _optional variant of devm_clk_get to make sure old DTs will still probe with newer versions of the driver.

interconnect: qcom: msm8996: Fix regmap max_register values

2023-01-05T15:29:50Z

The device tree reg starts at BUS_BASE + QoS_OFFSET, but the regmap configs in the ICC driver had values suggesting the reg started at BUS_BASE. Shrink them down (where they haven't been already, so for providers where QoS_OFFSET = 0) to make sure they stay within their window.

interconnect: qcom: msm8996: Provide UFS clocks to A2NoC

2023-01-05T15:29:40Z

On eMMC devices the bootloader has no business enabling UFS clocks. That results in a platform hang and hard reboot when trying to vote on paths including MASTER_UFS and since sync_state guarantees that it's done at boot time, this effectively prevents such devices from booting. Fix that.

Merge branch 'icc-sc8280xp-l3' into icc-next

2022-11-17T15:44:14Z

The SC8280XP currently shows depressing results in memory benchmarks. Fix this by introducing support for the platform in the OSM (and EPSS) L3 driver and support for the platform in the bwmon binding.

interconnect: qcom: osm-l3: Simplify osm_l3_set()

2022-11-14T13:05:30Z

The aggregation over votes for all nodes in the provider will always only find the bandwidth votes for the destination side of the path. Further more, the average kBps value will always be 0. Simplify the logic by directly looking at the destination node's peak bandwidth request.

interconnect: qcom: osm-l3: Add per-core EPSS L3 support

2022-11-14T13:05:30Z

The EPSS instance in e.g. SM8350 and SC8280XP has per-core L3 voting enabled. In this configuration, the "shared" vote is done using the REG_L3_VOTE register instead of PERF_STATE. Rename epss_l3 to clarify that it's affecting the PERF_STATE register and add a new L3_VOTE description. Given platform lineage it's assumed that the L3_VOTE-based case will be the predominant one, so use this for a new generic qcom,epss-l3 compatible. While adding the EPSS generic, also add qcom,osm-l3.
