0ac2a08f - interconnect: add clk-based icc provider support

Fri, 12 May 2023 00:13:32 +0000

interconnect: add clk-based icc provider supportFor some devices it is useful to export clocks as interconnect providers,if the clock corresponds to bus bandwidth.For example, on MSM8996 the cluster interconnect clock should be scaledaccording to the cluster frequencies. Exporting it as an interconnectallows one to properly describe this as the cluster bandwidthrequirements.Tested-by: Yassine Oudjana Signed-off-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/20230512001334.2983048-3-dmitry.baryshkov@linaro.orgSigned-off-by: Georgi Djakov List of files: /linux-6.15/drivers/interconnect/Kconfig

2f95b9d5 - interconnect: Add generic interconnect driver for Exynos SoCs

Thu, 12 Nov 2020 14:09:28 +0000

interconnect: Add generic interconnect driver for Exynos SoCsThis patch adds a generic interconnect driver for Exynos SoCs in orderto provide interconnect functionality for each "samsung,exynos-bus"compatible device.The SoC topology is a graph (or more specifically, a tree) and itsedges are described by specifying in the 'interconnects' propertythe interconnect consumer path for each interconnect provider DT node.Each bus is now an interconnect provider and an interconnect node aswell (cf. Documentation/interconnect/interconnect.rst), i.e. every busregisters itself as a node. Node IDs are not hard coded but ratherassigned dynamically at runtime. This approach allows for using thisdriver with various Exynos SoCs.Frequencies requested via the interconnect API for a given node arepropagated to devfreq using dev_pm_qos_update_request(). Please notethat it is not an error when CONFIG_INTERCONNECT is 'n', in whichcase all interconnect API functions are no-op.The samsung,data-clk-ratio DT property is used to specify the ratioof the interconect bandwidth to the minimum data clock frequencyfor each bus.Due to unspecified relative probing order, -EPROBE_DEFER may bepropagated to ensure that the parent is probed before its children.Reviewed-by: Chanwoo Choi Tested-by: Chanwoo Choi Acked-by: Krzysztof Kozlowski Signed-off-by: Artur Świgoń Signed-off-by: Sylwester Nawrocki Link: https://lore.kernel.org/r/20201112140931.31139-3-s.nawrocki@samsung.comSigned-off-by: Georgi Djakov List of files: /linux-6.15/drivers/interconnect/Kconfig

fcb57bfc - interconnect: Disallow interconnect core to be built as a module

Thu, 29 Aug 2019 08:07:29 +0000

interconnect: Disallow interconnect core to be built as a moduleBuilding individual drivers as modules is fine but allowing a coreframework to be built as a module makes it really complex and should beavoided.Whatever uses the interconnect core APIs must also be built as a moduleif interconnect core is built as module, else we will see compilationfailures.If another core framework (like cpufreq, clk, etc), that can't be builtas module, needs to use interconnect APIs then we will start seeingcompilation failures with allmodconfig configurations as the symbols(like of_icc_get()) used in other frameworks will not be available inthe built-in image.Disallow the interconnect core to be built as a module to avoid allthese issues.Signed-off-by: Viresh Kumar Reviewed-by: Bjorn Andersson Link: https://lore.kernel.org/r/b789cce388dd1f2906492f307dea6780c398bc6a.1567065991.git.viresh.kumar@linaro.orgSigned-off-by: Georgi Djakov List of files: /linux-6.15/drivers/interconnect/Kconfig

11f1ceca - interconnect: Add generic on-chip interconnect API

Wed, 16 Jan 2019 16:10:56 +0000

interconnect: Add generic on-chip interconnect APIThis patch introduces a new API to get requirements and configure theinterconnect buses across the entire chipset to fit with the currentdemand.The API is using a consumer/provider-based model, where the providers arethe interconnect buses and the consumers could be various drivers.The consumers request interconnect resources (path) between endpoints andset the desired constraints on this data flow path. The providers receiverequests from consumers and aggregate these requests for all master-slavepairs on that path. Then the providers configure each node along the pathto support a bandwidth that satisfies all bandwidth requests that crossthrough that node. The topology could be complicated and multi-tiered andis SoC specific.Reviewed-by: Evan Green Signed-off-by: Georgi Djakov Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/interconnect/Kconfig
