interconnect: qcom: Add SM6350 driver support

2022-06-20T11:27:07+00:00

Add a driver that handles the different NoCs found on SM6350, generated from the downstream dtb. We're exluding ALC, IP0 and all _display nodes. ALC will not be voted from the kernel[1] and IP0 is handled by the clk-rpmh driver[2].

interconnect: qcom: icc-rpmh: Support child NoC device probe

2022-06-20T11:21:15+00:00

As per e39bf2972c6e ("interconnect: icc-rpm: Support child NoC device probe") also update the rpmh interconnect driver to support probing NoCs that are modelled as child devices of a different NoC. As the driver doesn't yet use the 'reg' property, no change is done for that.

Merge branch 'icc-rpm' into icc-next

2022-05-18T00:03:30+00:00

This patch set is to address two clock rate setting issues. The first patch is to fix a potential cached clock rate mismatching issue, the issue can lead to the clock rate is missed to be set. Note, since this potential issue requires specific time window and certain condition (consumers need to request the same bandwidth) to produce, the patch is based on analysis but not a real trace log. The second patch is an extension to cache clock rates for active and sleep clocks separately, with this change it gives us possibility to set active and sleep clock with different clock rates. * icc-rpm interconnect: qcom: icc-rpm: Fix for cached clock rate interconnect: qcom: icc-rpm: Cache every clock rate Link: https://lore.kernel.org/r/20220416031029.693211-1-leo.yan@linaro.org Signed-off-by: Georgi Djakov

interconnect: qcom: sc8180x: Reformat node and bcm definitions

2022-05-17T23:51:34+00:00

The Qualcomm interconnect providers started off defining nodes and BCMs using the DEFINE_QNODE() and DEFINE_QBCM() macros. Unfortunately this results in a block of long lines that are hard to read, a transition to explicitly stated definition has been made for newly introduced platforms. Transition the SC8180X interconnect provider driver to this style as well, to make it easier to read while debugging interconnect related issues.

interconnect: qcom: sc8180x: Fix QUP0 nodes

2022-05-17T23:51:34+00:00

The QUP0 BCM relates to some internal property of the QUPs, and should be configured independently of the path to the QUP. In line with other platforms expose QUP_CORE endpoints in order allow this configuration.

interconnect: qcom: sc8180x: Modernize sc8180x probe

2022-05-17T23:51:33+00:00

The introduction of the Qualcomm SC8180X provider raced with the refactoring of the RPMh common code and SC8180X was left with the old style of duplicating the probe function in each provider driver. Transition the driver to the "new" design. Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20220503211925.1022169-3-bjorn.andersson@linaro.org Signed-off-by: Georgi Djakov
