Currently, the driver supports the burst with sync pulses mode only. Signed-off-by: Liu Ying --- v8->v9: * Rebase onto the imx-drm/next branch of Philipp Zabel's open git repository and adapt to bridge API change as the dw-hdmi driver did. * To address Philipp's comment, add a new required clock pclk and clean up clock-names. * Add driver copyright for 2015. v7->v8: * Fix the driver's Kconfig so that we may pass the allmodconfig for ARM. v6->v7: * None. v5->v6: * Make the checkpatch.pl script be happier. v4->v5: * Remove 'dsi->panel = NULL;' in dw_mipi_dsi_host_detach() to address Andrzej Hajda's comment. v3->v4: * Move the relevant dt-bindings to a separate patch to address Stefan Wahren's comment. v2->v3: * Newly introduced in v3 to address Andy Yan's comment. This is based on the i.MX MIPI DSI driver in v2. To make the Synopsys DesignWare MIPI DSI host controller driver less platform-dependant, this patch places it at the drm/bridge directory as a DRM bridge driver. drivers/gpu/drm/bridge/Kconfig | 10 + drivers/gpu/drm/bridge/Makefile | 1 + drivers/gpu/drm/bridge/dw_mipi_dsi.c | 1006 ++++++++++++++++++++++++++++++++++ include/drm/bridge/dw_mipi_dsi.h | 27 + 4 files changed, 1044 insertions(+) create mode 100644 drivers/gpu/drm/bridge/dw_mipi_dsi.c create mode 100644 include/drm/bridge/dw_mipi_dsi.h diff --git a/drivers/gpu/drm/bridge/Kconfig b/drivers/gpu/drm/bridge/Kconfig index f38bbcd..de151f2 100644 --- a/drivers/gpu/drm/bridge/Kconfig +++ b/drivers/gpu/drm/bridge/Kconfig @@ -3,6 +3,16 @@ config DRM_DW_HDMI depends on DRM select DRM_KMS_HELPER +config DRM_DW_MIPI_DSI + tristate "Synopsys DesignWare MIPI DSI host controller bridge" + depends on DRM + select DRM_KMS_HELPER + select DRM_MIPI_DSI + select DRM_PANEL + help + Choose this if you want to use the Synopsys DesignWare MIPI DSI host + controller bridge. + config DRM_PTN3460 tristate "PTN3460 DP/LVDS bridge" depends on DRM diff --git a/drivers/gpu/drm/bridge/Makefile b/drivers/gpu/drm/bridge/Makefile index d8a8cfd..5f8e9b3 100644 --- a/drivers/gpu/drm/bridge/Makefile +++ b/drivers/gpu/drm/bridge/Makefile @@ -2,3 +2,4 @@ ccflags-y := -Iinclude/drm obj-$(CONFIG_DRM_PTN3460) += ptn3460.o obj-$(CONFIG_DRM_DW_HDMI) += dw_hdmi.o +obj-$(CONFIG_DRM_DW_MIPI_DSI) += dw_mipi_dsi.o diff --git a/drivers/gpu/drm/bridge/dw_mipi_dsi.c b/drivers/gpu/drm/bridge/dw_mipi_dsi.c new file mode 100644 index 0000000..0ff241e --- /dev/null +++ b/drivers/gpu/drm/bridge/dw_mipi_dsi.c @@ -0,0 +1,1006 @@ +/* + * Synopsys DesignWare(DW) MIPI DSI Host Controller + * + * Copyright (C) 2011-2015 Freescale Semiconductor, Inc. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
