Hi! It was noted by Russel King [1] that bridges (not using components) might disappear unexpectedly if the owner of the bridge was unbound. Jyri Sarha had previously noted the same thing with panels [2]. Jyri came up with using device links to resolve the panel issue, which was also my (independent) reaction to the note from Russel. This series builds up to the addition of that link in the last patch, but in my opinion the other 23 patches do have merit on their own. The last patch needs testing, while the others look trivial. That said, I might have missed some subtlety. Cheers, Peter [1] https://lkml.org/lkml/2018/4/23/769 [2] https://www.spinics.net/lists/dri-devel/msg174275.html Peter Rosin (24): drm/bridge: allow optionally specifying an .owner device drm/bridge: adv7511: provide an .owner device drm/bridge/analogix: core: specify the .owner of the bridge drm/bridge: analogix-anx78xx: provide an .owner device drm/bridge: vga-dac: provide an .owner device drm/bridge: lvds-encoder: provide an .owner device drm/bridge: megachips-stdpxxxx-ge-b850v3-fw: provide an .owner device drm/bridge: nxp-ptn3460: provide an .owner device drm/bridge: panel: provide an .owner device drm/bridge: ps8622: provide an .owner device drm/bridge: sii902x: provide an .owner device drm/bridge: sii9234: provide an .owner device drm/bridge: sii8620: provide an .owner device drm/bridge: synopsys: provide an .owner device for the bridges drm/bridge: tc358767: provide an .owner device drm/bridge: ti-tfp410: provide an .owner device drm/exynos: mic: provide an .owner device for the bridge drm/mediatek: hdmi: provide an .owner device for the bridge drm/msm: specify the .owner of the bridges drm/rcar-du: lvds: provide an .owner device for the bridge drm/sti: provide an .owner device for the bridges drm/bridge: remove the .of_node member drm/bridge: require the .owner to be filled in on drm_bridge_attach drm/bridge: establish a link between the bridge supplier and consumer drivers/gpu/drm/bridge/adv7511/adv7511_drv.c | 2 +- drivers/gpu/drm/bridge/analogix-anx78xx.c | 5 +---- drivers/gpu/drm/bridge/analogix/analogix_dp_core.c | 1 + drivers/gpu/drm/bridge/dumb-vga-dac.c | 2 +- drivers/gpu/drm/bridge/lvds-encoder.c | 2 +- .../drm/bridge/megachips-stdpxxxx-ge-b850v3-fw.c | 2 +- drivers/gpu/drm/bridge/nxp-ptn3460.c | 2 +- drivers/gpu/drm/bridge/panel.c | 4 +--- drivers/gpu/drm/bridge/parade-ps8622.c | 2 +- drivers/gpu/drm/bridge/sii902x.c | 2 +- drivers/gpu/drm/bridge/sii9234.c | 2 +- drivers/gpu/drm/bridge/sil-sii8620.c | 2 +- drivers/gpu/drm/bridge/synopsys/dw-hdmi.c | 4 +--- drivers/gpu/drm/bridge/synopsys/dw-mipi-dsi.c | 4 +--- drivers/gpu/drm/bridge/tc358767.c | 2 +- drivers/gpu/drm/bridge/ti-tfp410.c | 2 +- drivers/gpu/drm/drm_bridge.c | 23 +++++++++++++++++++++- drivers/gpu/drm/exynos/exynos_drm_mic.c | 2 +- drivers/gpu/drm/mediatek/mtk_hdmi.c | 2 +- drivers/gpu/drm/msm/dsi/dsi_manager.c | 1 + drivers/gpu/drm/msm/edp/edp_bridge.c | 1 + drivers/gpu/drm/msm/hdmi/hdmi_bridge.c | 1 + drivers/gpu/drm/rcar-du/rcar_lvds.c | 2 +- drivers/gpu/drm/sti/sti_dvo.c | 2 +- drivers/gpu/drm/sti/sti_hda.c | 1 + drivers/gpu/drm/sti/sti_hdmi.c | 1 + include/drm/drm_bridge.h | 8 ++++---- 27 files changed, 51 insertions(+), 33 deletions(-) -- 2.11.0 -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
