This updates the existing omapdrm DSI code, so that it uses common drm_mipi_dsi API and drm_panel instead of custom API. I did not implement support for drm_bridge, since I do not own any hardware needing this and it does not seem to be a supported scenario with the old DSS code. The patchset has been tested with Droid 4 using Linux console, X.org and Weston. While I found some issues, I could not find any regressions compared to the current state (*). Combined with Laurent's effort this will remove all custom panel/connector drivers from omapdrm and allow more cleanups in the DSS code. I pushed this patchset into the following branch: https://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-n900.git/log/?h=omapdrm-dsi-drm-panel (*) When display is used as console for dmesg one can see an ugly deadlock on shutdown. I have not yet found the root cause for this problem, but that already exists with current mainline implementation. -- Sebastian Sebastian Reichel (42): omap/drm: drop unused dsi.configure_pins drm/omap: dsi: use MIPI_DSI_FMT_* instead of OMAP_DSS_DSI_FMT_* drm/omap: constify write buffers drm/omap: dsi: add generic transfer function drm/omap: panel-dsi-cm: convert to transfer API drm/omap: dsi: unexport specific data transfer functions drm/omap: dsi: drop virtual channel logic drm/omap: dsi: simplify write function drm/omap: dsi: simplify read functions drm/omap: dsi: switch dsi_vc_send_long/short to mipi_dsi_msg ARM: dts: omap: add channel to DSI panels drm/omap: dsi: introduce mipi_dsi_host drm/omap: panel-dsi-cm: use DSI helpers drm/omap: dsi: request VC via mipi_dsi_attach drm/omap: panel-dsi-cm: drop hardcoded VC drm/omap: panel-dsi-cm: use common MIPI DCS 1.3 defines drm/omap: dsi: drop unused memory_read() drm/omap: dsi: drop unused get_te() drm/omap: dsi: drop unused enable_te() drm/omap: dsi: drop useless sync() drm/omap: dsi: use pixel-format and mode from attach drm/omap: panel-dsi-cm: use bulk regulator API drm/omap: dsi: lp/hs switching support for transfer() drm/omap: dsi: move TE GPIO handling into core drm/omap: dsi: drop custom enable_te() API drm/omap: dsi: do bus locking in host driver drm/omap: dsi: untangle ulps ops from enable/disable drm/dsi: add MIPI_DSI_MODE_ULPS_IDLE drm/omap: dsi: do ULPS in host driver drm/omap: dsi: move panel refresh function to host drm/omap: dsi: Reverse direction of the DSS device enable/disable operations drm/omap: dsi: convert to drm_panel drm/omap: dsi: use atomic helper for dirtyfb drm/omap: dsi: implement check timings drm/omap: panel-dsi-cm: use DEVICE_ATTR_RO drm/omap: panel-dsi-cm: support unbinding drm/omap: panel-dsi-cm: fix remove() drm/omap: panel-dsi-cm: do not power on/off twice drm/omap: dsi: return proper error code from dsi_update_all() drm/omap: dsi: support panel un/re-binding ARM: dts: omap4-droid4: add panel compatible drm/panel: Move OMAP's DSI command mode panel driver .../bindings/display/panel/panel-dsi-cm.txt | 4 +- arch/arm/boot/dts/omap3-n950.dts | 3 +- arch/arm/boot/dts/omap3.dtsi | 3 + arch/arm/boot/dts/omap4-droid4-xt894.dts | 5 +- arch/arm/boot/dts/omap4-sdp.dts | 6 +- arch/arm/boot/dts/omap4.dtsi | 6 + arch/arm/boot/dts/omap5.dtsi | 6 + drivers/gpu/drm/omapdrm/displays/Kconfig | 6 - drivers/gpu/drm/omapdrm/displays/Makefile | 1 - .../gpu/drm/omapdrm/displays/panel-dsi-cm.c | 1387 ----------------- drivers/gpu/drm/omapdrm/dss/Kconfig | 1 + drivers/gpu/drm/omapdrm/dss/base.c | 2 +- drivers/gpu/drm/omapdrm/dss/dsi.c | 1019 ++++++++---- .../gpu/drm/omapdrm/dss/omapdss-boot-init.c | 1 - drivers/gpu/drm/omapdrm/dss/omapdss.h | 81 +- drivers/gpu/drm/omapdrm/omap_crtc.c | 37 +- drivers/gpu/drm/omapdrm/omap_crtc.h | 1 - drivers/gpu/drm/omapdrm/omap_encoder.c | 20 +- drivers/gpu/drm/omapdrm/omap_fb.c | 21 +- drivers/gpu/drm/panel/Kconfig | 9 + drivers/gpu/drm/panel/Makefile | 1 + drivers/gpu/drm/panel/panel-dsi-cm.c | 646 ++++++++ include/drm/drm_mipi_dsi.h | 2 + 23 files changed, 1385 insertions(+), 1883 deletions(-) delete mode 100644 drivers/gpu/drm/omapdrm/displays/panel-dsi-cm.c create mode 100644 drivers/gpu/drm/panel/panel-dsi-cm.c base-commit: 17cc51390c141662748dbbc2fe98f3ed10f2e13e -- 2.24.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
