This RFC prepares for and adds support for 2 buses, which is supported in HW starting with version 7. Until now, none of the currently supported platforms in upstream have used the second bus. The X1E80100 platform, on the other hand, needs the second bus for the USB2.0 to work as there are 3 SMB2360 PMICs which provide eUSB2 repeaters and they are all found on the second bus. Signed-off-by: Abel Vesa <abel.vesa@xxxxxxxxxx> --- Changes in v3: - Split the change into 3 separate patches. First 2 patches are moving apid init and core resources into version specific ops. Third one is adding the support for 2 buses and dedicated compatible. - Added separate bindings patch - Link to v2: https://lore.kernel.org/r/20240213-spmi-multi-master-support-v2-1-b3b102326906@xxxxxxxxxx Changes in v2: - Reworked it so that it registers a spmi controller for each bus rather than relying on the generic framework to pass on the bus (master) id. - Link to v1: https://lore.kernel.org/r/20240207-spmi-multi-master-support-v1-0-ce57f301c7fd@xxxxxxxxxx --- Abel Vesa (4): dt-bindings: spmi: Add PMIC ARB v7 schema spmi: pmic-arb: Make the APID init a version operation spmi: pmic-arb: Make core resources acquiring a version operation spmi: pmic-arb: Add multi bus support .../bindings/spmi/qcom,spmi-pmic-arb-v7.yaml | 119 +++ drivers/spmi/spmi-pmic-arb.c | 956 +++++++++++++-------- 2 files changed, 712 insertions(+), 363 deletions(-) --- base-commit: 2c3b09aac00d7835023bbc4473ee06696be64fa8 change-id: 20240207-spmi-multi-master-support-832a704b779b Best regards, -- Abel Vesa <abel.vesa@xxxxxxxxxx>
