Merge branch 'icc-rpm' into icc-next

2022-07-15T14:56:31Z

This patch set is to support bucket in icc-rpm driver, so it implements the similar mechanism in the icc-rpmh driver. It uses interconnect path tag to indicate the bandwidth voting is for which buckets, and there have three kinds of buckets: AWC, WAKE and SLEEP, finally the wake and sleep bucket values are used to set the corresponding clock (active and sleep clocks). So far, we keep the AWC bucket but doesn't really use it. Link: https://lore.kernel.org/r/20220712015929.2789881-1-leo.yan@linaro.org Signed-off-by: Georgi Djakov

Merge branch 'icc-imx8mp' into icc-next

2022-07-15T14:55:48Z

This patchset is to support i.MX8MP NoC settings, i.MX8MP NoC initial value after power up is invalid, need set a valid value after related power domain up. This patchset also includes two patch[1,2] during my development to enable the ICC feature for i.MX8MP. I not include ddrc DVFS in this patchset, ths patchset is only to support NoC value mode/priority/ext_control being set to a valid value that suggested by i.MX Chip Design Team. The value is same as NXP downstream one inside Arm Trusted Firmware: https://source.codeaurora.org/external/imx/imx-atf/tree/plat/imx/imx8m/i/gpc.c?h=lf_v2.4#n97 Link: https://lore.kernel.org/r/20220703091132.1412063-1-peng.fan@oss.nxp.com Signed-off-by: Georgi Djakov

max_node_id not equal to the ARRAY_SIZE of node array, need increase 1, otherwise xlate will fail for the last entry. And rename max_node_id to num_nodes to reflect the reality.

interconnect: qcom: icc-rpm: Set bandwidth and clock for bucket values

2022-07-12T07:04:01Z

This commit uses buckets for support bandwidth and clock rates. It introduces a new function qcom_icc_bus_aggregate() to calculate the aggregate average and peak bandwidths for every bucket, and also it calculates the maximum value of aggregated average bandwidth across all buckets. The maximum aggregated average is used to calculate the final bandwidth requests. And we can set the clock rate per bucket, we use SLEEP bucket as default bucket if a platform doesn't enable the interconnect path tags in DT binding; otherwise, we use WAKE bucket to set active clock and use SLEEP bucket for other clocks. So far we don't use AMC bucket. Signed-off-by: Leo Yan Link: https://lore.kernel.org/r/20220712015929.2789881-6-leo.yan@linaro.org Signed-off-by: Georgi Djakov

interconnect: qcom: icc-rpm: Support multiple buckets

2022-07-12T07:03:09Z

The current interconnect rpm driver uses a single aggregate bandwidth to calculate the clock rates for both active and sleep clocks; therefore, it has no chance to separate bandwidth requests for these two kinds of clocks. This patch studies the implementation from interconnect rpmh driver to support multiple buckets. The rpmh driver provides three buckets for AMC, WAKE, and SLEEP; this driver only needs to use WAKE and SLEEP buckets, but we keep the same way with rpmh driver, this can allow us to reuse the DT binding and avoid to define duplicated data structures. This patch introduces two callbacks: qcom_icc_pre_bw_aggregate() is used to clean up bucket values before aggregate bandwidth requests, and qcom_icc_bw_aggregate() is to aggregate bandwidth for buckets.

interconnect: qcom: icc-rpm: Change to use qcom_icc_xlate_extended()

2022-07-12T07:03:01Z

This commit changes to use callback qcom_icc_xlate_extended(). This is a preparation for population path tags from the interconnect DT binding, it doesn't introduce functionality change for the existed DT binding without path tags.
