I've introduced an 'aggregate' bus that we put the aggregate device onto and then we probe the aggregate device once all the components are probed and call component_add(). The probe/remove hooks are where the bind/unbind calls go, and then a shutdown hook is added that can be used to shutdown the drm display pipeline at the right time. This works for me on my sc7180 board. I no longer get a warning from i2c at shutdown that we're trying to make an i2c transaction after the i2c bus has been shutdown. There's more work to do on the msm drm driver to extract component device resources like clks, regulators, etc. out of the component bind function into the driver probe but I wanted to move everything over now in other component drivers before tackling that problem. Tested-by tags would be appreciated, and Acked-by/Reviewed-by tags too. Per Daniel, I've resent this to collect Acks or Review tags from gregkh and once Greg is happy with the driver core bits it can be merged through drm-misc tree via dianders (both are on the To line). Changes since v5 (https://lore.kernel.org/r/20220106214556.2461363-1-swboyd@chromium.org): - Refcount the driver registration to support multiple device usage - Fix runtime PM in MediaTek iommu patch - Rebased to v5.17-rc1 and converted new component uses - No longer expose struct aggregate_device in component.h header Changes since v4 (https://lore.kernel.org/r/20211202222732.2453851-1-swboyd@chromium.org): -

Rebased to v5.16-rc2 - Updated component.c for a few new patches there - Dropped a conversion patch - Added a conversion patch Changes since v2 (https://lore.kernel.org/r/20211006193819.2654854-1-swboyd@chromium.org): - Picked up acks - Fixed build warnings/errors - Reworked patch series to rename 'master' in a different patch Changes since v1 (https://lore.kernel.org/r/20210520002519.3538432-1-swboyd@chromium.org): - Use devlink to connect components to the aggregate device - Don't set the registering device as a parent of the aggregate device - New patch for bind_component/unbind_component ops that takes the aggregate device - Convert all drivers in the tree to use the aggregate driver approach - Allow one aggregate driver to be used for multiple aggregate devices [1] https://lore.kernel.org/r/20210508074118.1621729-1-swboyd@chromium.org Stephen Boyd (35): component: Replace most references to 'master' with 'aggregate device' component: Introduce the aggregate bus_type component: Add aggregate_device_parent() for driver use component: Add {bind,unbind}_component() ops that take aggregate device drm/of: Add a drm_of_aggregate_probe() API drm/msm: Migrate to aggregate driver drm/komeda: Migrate to aggregate driver drm/arm/hdlcd: Migrate to aggregate driver drm/malidp: Migrate to aggregate driver drm/armada: Migrate to aggregate driver drm/etnaviv: Migrate to aggregate driver drm/kirin: Migrate to aggregate driver drm/exynos: Migrate to aggregate driver drm/imx: Migrate to aggregate driver drm/ingenic: Migrate to aggregate driver drm/mcde: Migrate to aggregate driver drm/mediatek: Migrate to aggregate driver drm/meson: Migrate to aggregate driver drm/omap: Migrate to aggregate driver drm/rockchip: Migrate to aggregate driver drm/sti: Migrate to aggregate driver drm/sun4i: Migrate to aggregate driver drm/tilcdc: Migrate to aggregate driver drm/vc4: Migrate to aggregate driver iommu/mediatek: Migrate to aggregate driver mei: Migrate to aggregate driver power: supply: ab8500: Migrate to aggregate driver fbdev: omap2: Migrate to aggregate driver sound: hdac: Migrate to aggregate driver ASoC: codecs: wcd938x: Migrate to aggregate driver drm/sprd: Migrate to aggregate driver usb: typec: port-mapper: Migrate to aggregate driver ALSA: hda/realtek: Migrate to aggregate driver component: Get rid of drm_of_component_probe() component: Remove component_master_ops and friends drivers/base/component.c | 571 +++++++++++------- .../gpu/drm/arm/display/komeda/komeda_drv.c | 20 +- drivers/gpu/drm/arm/hdlcd_drv.c | 21 +- drivers/gpu/drm/arm/malidp_drv.c | 21 +- drivers/gpu/drm/armada/armada_drv.c | 23 +- drivers/gpu/drm/drm_drv.c | 2 +- drivers/gpu/drm/drm_of.c | 18 +- drivers/gpu/drm/etnaviv/etnaviv_drv.c | 20 +- drivers/gpu/drm/exynos/exynos_drm_drv.c | 21 +- .../gpu/drm/hisilicon/kirin/kirin_drm_drv.c | 20 +- drivers/gpu/drm/imx/imx-drm-core.c | 20 +- drivers/gpu/drm/ingenic/ingenic-drm-drv.c | 25 +- drivers/gpu/drm/mcde/mcde_drv.c | 23 +- drivers/gpu/drm/mediatek/mtk_drm_drv.c | 20 +- drivers/gpu/drm/meson/meson_drv.c | 21 +- drivers/gpu/drm/msm/msm_drv.c | 48 +- drivers/gpu/drm/omapdrm/dss/dss.c | 20 +- drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 20 +- drivers/gpu/drm/sprd/sprd_drm.c | 48 +- drivers/gpu/drm/sti/sti_drv.c | 20 +- drivers/gpu/drm/sun4i/sun4i_drv.c | 26 +- drivers/gpu/drm/tilcdc/tilcdc_drv.c | 28 +- drivers/gpu/drm/vc4/vc4_drv.c | 20 +- drivers/iommu/mtk_iommu.c | 14 +- drivers/iommu/mtk_iommu.h | 6 +- drivers/iommu/mtk_iommu_v1.c | 14 +- drivers/memory/mtk-smi.c | 10 +- drivers/misc/mei/hdcp/mei_hdcp.c | 22 +- drivers/misc/mei/pxp/mei_pxp.c | 22 +- drivers/power/supply/ab8500_charger.c | 22 +- drivers/usb/typec/port-mapper.c | 22 +- drivers/video/fbdev/omap2/omapfb/dss/dss.c | 20 +- include/drm/drm_of.h | 10 +- include/linux/component.h | 96 ++- sound/hda/hdac_component.c | 21 +- sound/pci/hda/patch_realtek.c | 20 +- sound/soc/codecs/wcd938x.c | 20 +- 37 files changed, 863 insertions(+), 532 deletions(-) Cc: Arnd Bergmann Cc: Baolin Wang Cc: Chen Feng Cc: Chen-Yu Tsai Cc: Christian Gmeiner Cc: Chun-Kuang Hu Cc: Chunyan Zhang Cc: Daniel Vetter Cc: Emma Anholt Cc: Greg Kroah-Hartman Cc: Heikki Krogerus Cc: "Heiko Stübner" Cc: Inki Dae Cc: James Qian Wang (Arm Technology China) Cc: Jaroslav Kysela Cc: Joerg Roedel Cc: John Stultz Cc: Joonyoung Shim Cc: Jyri Sarha Cc: Kai Vehmanen Cc: Kevin Tang Cc: Kyungmin Park Cc: Laurent Pinchart Cc: Cc: Cc: Cc: Linus Walleij Cc: Liviu Dudau Cc: Lucas Stach Cc: Lucas Tanure Cc: Maarten Lankhorst Cc: Mark Brown Cc: Maxime Ripard Cc: Neil Armstrong Cc: Orson Zhai Cc: Paul Cercueil Cc: Philipp Zabel Cc: "Rafael J.
