interconnect: qcom: sm8550: add enable_mask for bcm nodes

2023-08-16T16:32:23+00:00

commit 0dc82bd9e4627065dbc6ac8468296aa18f13c840 upstream.

Set the proper enable_mask to nodes requiring such value
to be used instead of a bandwidth when voting.

The masks were copied from the downstream implementation at [1].

interconnect: qcom: Add support for mask-based BCMs

2023-08-16T16:32:23+00:00

commit d8630f050d3fd2079f8617dd6c00c6509109c755 upstream.

Some BCMs aren't directly associated with the data path (i.e. ACV) and
therefore don't communicate using BW. Instead, they are simply
enabled/disabled with a simple bit mask. Add support for these.

interconnect: qcom: rpm: Don't use clk_get_optional for bus clocks anymore

2023-07-19T14:36:27+00:00

[ Upstream commit 1ff7aedcdcdd4fe02201269ab428b09491e5cf6e ]

Commit dd42ec8ea5b9 ("interconnect: qcom: rpm: Use _optional func for provider clocks")
relaxed the requirements around probing bus clocks. This was a decent
solution for making sure MSM8996 would still boot with old DTs, but
now that there's a proper fix in place that both old and new DTs
will be happy about, revert back to the safer variant of the
function.

interconnect: qcom: rpm: Add support for specifying channel num

2023-04-05T08:29:59+00:00

Some nodes, like EBI0 (DDR) or L3/LLCC, may be connected over more than
one channel. This should be taken into account in bandwidth calcualtion,
as we're supposed to feed msmbus with the per-channel bandwidth. Add
support for specifying that and use it during bandwidth aggregation.

interconnect: qcom: rpm: make QoS INVALID default

2023-04-05T08:29:59+00:00

Currently NOC_QOS_MODE_FIXED is defined as 0x0 which makes it the
default option (partial struct initialization). The default option
however should be NOC_QOS_MODE_INVALID.

That results in bogus QoS configurations being sent for port 0 (which
is used for the DRAM endpoint on BIMC, for example) coming from all nodes
with .qos.ap_owned = true and uninitialized .qos.qos_mode. It's also an
issue for newer SoCs where all nodes are treated as if they were ap_owned,
but not all of them have QoS configuration.

The NOC_QOS_MODEs are defined as preprocessor constants and are not used
anywhere outside qcom_icc_set_noc_qos(), which is easily worked around.
Separate the desc->type values from the values sent to msmbus in the
aforementioned function. Make the former an enum for better mainainability.

interconnect: qcom: rpm: drop bogus pm domain attach

2023-04-05T08:29:59+00:00

Any power domain would already have been attached by the platform bus
code so drop the bogus power domain attach which always succeeds from
probe.

This effectively reverts commit 7de109c0abe9 ("interconnect: icc-rpm:
Add support for bus power domain").
