The probe function needs to get ahold of the panel device tree node, and it achieves that by using a combination of of_graph_get_port_by_id, of_get_child_by_name, and of_graph_get_remote_port_parent. We can achieve the same goal by replacing those calls with a call to of_graph_get_remote_node these days. Signed-off-by:

Add support for transparent LVDS decoders by adding a new compatible string ("lvds-decoder") to the driver. This patch also adds member connector_type to struct lvds_codec, and that's because LVDS decoders have a different connector type from LVDS encoders.

lvds-encoder.c implementation is also suitable for LVDS decoders, not just LVDS encoders. Instead of creating a new driver for addressing support for transparent LVDS decoders, repurpose lvds-encoder.c for the greater good with this patch. This patch only "rebrands" the lvds-encoder.c driver, to make it suitable for hosting LVDS decoders support. The actual support for LVDS decoders will come with a later patch. Signed-off-by:

I'm just going to put Chia's review comment here since it sums the issue rather nicely: "(1) Semantically, a dma-buf is in DMA domain. CPU access from the importer must be surrounded by {begin,end}_cpu_access. This gives the exporter a chance to move the buffer to the CPU domain temporarily. (2) When the exporter itself has other means to do CPU access, it is only reasonable for the exporter to move the buffer to the CPU domain before access, and to the DMA domain after access. The exporter can potentially reuse {begin,end}_cpu_access for that purpose. Because of (1), udmabuf does need to implement the {begin,end}_cpu_access hooks. But "begin" should mean dma_sync_sg_for_cpu and "end" should mean dma_sync_sg_for_device. Because of (2), if userspace wants to continuing accessing through the memfd mapping, it should call udmabuf's {begin,end}_cpu_access to avoid cache issues."

The video DSI mode had not really been tested. These fixes makes it more likely to work on real hardware: - Put the active width (x width) in the right bits and the VSA (vertical sync active) in the right bits (those were swapped). - Calculate the packet sizes in bytes as in the vendor driver, rather than in bits. Test the calculations agains a spreadsheet and confirmed by debug prints to be reasonable. - Also verified the register values with relative confidence to register dumps from the Samsung GT-I8190 boot loader graphics. We are not identical but not off by far either. - Error out if the current mode and refresh frequency doesn't work out. (In the future we may simply want to scale down the vrefresh.) - Handle negative result in front/back/sync packages and fall back to zero like in the vendor driver. - Put in lots of clarifying comments and references to the documentation where the code is hard to understand. - Set the DSI_VID_VCA_SETTING2 field DSI_VID_VCA_SETTING2_MAX_LINE_LIMIT to blkline_pck - 6 as in the vendor driver and mask the field properly. - Set the DSI_VID_VCA_SETTING1 field DSI_VID_VCA_SETTING1_MAX_BURST_LIMIT to blkeol_pck - 6 to blkeol_duration - 6 as in the vendor driver.

Add new struct drm_device based logging macros modeled after the core kernel device based logging macros. These would be preferred over the drm printk and struct device based macros in drm code, where possible. We have existing drm specific struct device based logging functions, but they are too verbose to use for two main reasons: * The names are unnecessarily long, for example DRM_DEV_DEBUG_KMS(). * The use of struct device over struct drm_device is too generic for most users, leading to an extra dereference. For example: DRM_DEV_DEBUG_KMS(drm->dev, "Hello, world\n"); vs. drm_dbg_kms(drm, "Hello, world\n"); It's a matter of taste, but the SHOUTING UPPERCASE has been argued to be less readable than lowercase. Some names are changed from old DRM names to be based on the core kernel logging functions. For example, NOTE -> notice, ERROR -> err, DEBUG -> dbg. Due to the conflation of DRM_DEBUG and DRM_DEBUG_DRIVER macro use (DRM_DEBUG is used widely in drivers though it's supposed to be a core debugging category), they are named as drm_dbg_core and drm_dbg, respectively. The drm_err and _once/_ratelimited variants no longer include the function name in order to be able to use the core device based logging macros. Arguably this is not a significant change; error messages should not be so common to be only distinguishable by the function name. Ratelimited debug logging macros are to be added later.
