interconnect: qcom: msm8974: fix registration race

2023-03-22T12:38:00+00:00

commit bfe7bcd2b9f5215de2144f097f39971180e7ea54 upstream.

The current interconnect provider registration interface is inherently
racy as nodes are not added until the after adding the provider. This
can specifically cause racing DT lookups to fail.

Switch to using the new API where the provider is not registered until
after it has been fully initialised.

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

2023-01-05T15:29:57+00:00

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

2023-01-05T15:29:50+00:00

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

2023-01-05T15:29:40+00:00

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

2022-11-17T15:44:14+00:00

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.
