Add drivers to support scaling of the on-chip interconnects on QCS404-based platforms. Also add the necessary device-tree nodes, so that the driver for each NoC can probe and register as interconnect-provider. The plan is to get patches 2,5 through the Qcom/ARM tree and the rest through the interconnect tree. v5: - Make reg and clocks DT properties required. (Bjorn) - Remove _clk suffix from clock names. (Bjorn) - Use the more succinct return !!icc_smd_rpm; (Bjorn) v4: https://lore.kernel.org/lkml/20190613151323.10850-1-georgi.djakov@xxxxxxxxxx/ - Move DT headers into the dt-bindings patch (Bjorn) - Pick Bjorn's r-b on some patches. - Return error if platform_device_register_data() fails (Bjorn) - Use platform_set_drvdata() only in the child device. (Bjorn) - Hide the smd-rpm proxy driver from config menu. (Bjorn) - Add remove() function to zero out the rpm handle. (Bjorn) - Move move the qcs404 driver patch later in the serie. (Bjorn) - Insert the DT nodes after rng to keep the list sorted by address. (Bjorn) v3: https://lore.kernel.org/lkml/20190611164157.24656-1-georgi.djakov@xxxxxxxxxx/ - Drop the patch introducing the qcom,qos DT property. - Add two new patches to create an interconnect proxy device. This device is part of the RPM hardware and handles the communication of the bus bandwidth requests. - Add a DT reg property and move the interconnect nodes under the "soc" node. v2: https://lore.kernel.org/lkml/20190415104357.5305-1-georgi.djakov@xxxxxxxxxx/ - Use the clk_bulk API. (Bjorn) - Move the port IDs into the provider file. (Bjorn) - Use ARRAY_SIZE in the macro to automagically count the num_links. (Bjorn) - Improve code readability. (Bjorn) - Add patch [4/4] introducing a qcom,qos DT property to represent the link to the MMIO QoS registers HW block. v1: https://lore.kernel.org/lkml/20190405035446.31886-1-georgi.djakov@xxxxxxxxxx/ Bjorn Andersson (1): interconnect: qcom: Add QCS404 interconnect provider driver Georgi Djakov (4): dt-bindings: interconnect: Add Qualcomm QCS404 DT bindings soc: qcom: smd-rpm: Create RPM interconnect proxy child device interconnect: qcom: Add interconnect SMD over SMD driver arm64: dts: qcs404: Add interconnect provider DT nodes .../bindings/interconnect/qcom,qcs404.txt | 45 ++ arch/arm64/boot/dts/qcom/qcs404.dtsi | 28 + drivers/interconnect/qcom/Kconfig | 12 + drivers/interconnect/qcom/Makefile | 4 + drivers/interconnect/qcom/qcs404.c | 539 ++++++++++++++++++ drivers/interconnect/qcom/smd-rpm.c | 77 +++ drivers/interconnect/qcom/smd-rpm.h | 15 + drivers/soc/qcom/smd-rpm.c | 17 +- .../dt-bindings/interconnect/qcom,qcs404.h | 88 +++ 9 files changed, 824 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/interconnect/qcom,qcs404.txt create mode 100644 drivers/interconnect/qcom/qcs404.c create mode 100644 drivers/interconnect/qcom/smd-rpm.c create mode 100644 drivers/interconnect/qcom/smd-rpm.h create mode 100644 include/dt-bindings/interconnect/qcom,qcs404.h
