Patch 1/5 and 2/5 adds a new bus_type and registers them to vchiq interface Patch 3/5 and 4/5 moves the bcm2835-camera and bcm2835-audio to the new bus respectively Patch 5/5 removes a platform registeration helper which is no longer required. Changes in v7: (5 out of 6 patches from v6 merged) - Split the main patch (6/6) as requested. - Use struct vchiq_device * instead of struct device * in all bus functions. - Drop additional name attribute displayed in sysfs (redundant info) - Document vchiq_interface doesn't enumerate device discovery - remove EXPORT_SYMBOL_GPL(vchiq_bus_type) Changes in v6: - Split struct device and struct driver wrappers in vchiq_device.[ch] - Move vchiq_bus_type definition to vchiq_device.[ch] as well - return error on bus_register() failure - drop dma_set_mask_and_coherent - trivial variable name change Changes in v5: - Fixup missing "staging: " in commits' subject line - No code changes from v4 Changes in v4: - Introduce patches to drop include directives from Makefile Changes in v3: - Rework entirely to replace platform devices/driver model -v2: https://lore.kernel.org/all/20221222191500.515795-1-umang.jain@ideasonboard.com/ -v1: https://lore.kernel.org/all/20221220084404.19280-1-umang.jain@ideasonboard.com/ Umang Jain (5): staging: vc04_services: vchiq_arm: Add new bus type and device type staging: vc04_services: vchiq_arm: Register vchiq_bus_type staging: bcm2835-camera: Register bcm2835-camera with vchiq_bus_type staging: bcm2835-audio: Register bcm2835-audio with vchiq_bus_type staging: vc04_services: vchiq_arm: Remove vchiq_register_child() drivers/staging/vc04_services/Makefile | 1 + .../vc04_services/bcm2835-audio/bcm2835.c | 17 ++-- .../bcm2835-camera/bcm2835-camera.c | 16 ++-- .../interface/vchiq_arm/vchiq_arm.c | 56 +++++++------ .../interface/vchiq_arm/vchiq_device.c | 78 +++++++++++++++++++ .../interface/vchiq_arm/vchiq_device.h | 43 ++++++++++ 6 files changed, 165 insertions(+), 46 deletions(-) create mode 100644 drivers/staging/vc04_services/interface/vchiq_arm/vchiq_device.c create mode 100644 drivers/staging/vc04_services/interface/vchiq_arm/vchiq_device.h
