interconnect: qcom: sm8450: switch to qcom_icc_rpmh_* function

2023-03-06T14:48:32+00:00

Change sm8450 interconnect driver to use generic qcom_icc_rpmh_* functions rather than embedding a copy of thema. This also fixes an overallocation of memory for icc_onecell_data structure.

interconnect: sm8450: Ignore return value of icc_provider_del() in .remove()

2022-08-16T13:38:35+00:00

icc_provider_del() already emits an error message on failure. In this case letting .remove() return the corresponding error code results in another error message and the device is removed anyhow. (See platform_remove().) So ignore the return value of icc_provider_del() and return 0 unconditionally. This is a preparation for making platform remove callbacks return void.

interconnect: qcom: Move qcom_icc_xlate_extended() to a common file

2022-07-12T07:01:30+00:00

since there have conflict between two headers icc-rpmh.h and icc-rpm.h, the function qcom_icc_xlate_extended() is declared in icc-rpmh.h thus it cannot be used by icc-rpm driver. Move the function to a new common file icc-common.c so that allow it to be called by multiple drivers.

interconnect: qcom: constify qcom_icc_bcm pointers

Pointers to struct qcom_icc_bcm are not modified, so they can be made const for safety. The contents of struct qcom_icc_bcm must stay non-const. Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20220412102623.227607-3-krzysztof.kozlowski@linaro.org Signed-off-by: Georgi Djakov

interconnect: qcom: Add SM8450 interconnect provider driver

2021-12-14T21:43:26+00:00

Add driver for the Qualcomm interconnect buses found in SM8450 based platforms. The topology consists of several NoCs that are controlled by a remote processor that collects the aggregated bandwidth for each master-slave pairs.
