The servers for the @codeaurora domain are long retired and any messages sent there bounce. Sandeep Panda's email address is no longer valid and should be repleaced. However Sandeep has left the company and has not been active sice, therefore it looks like this binding is orphaned. Doug is listed as the reviewer for this file in MAINTAINERS and has volunteered to be listed within the file as the binding maintainer. Therefore replace Sandeep with Doug to make the documentation current. Signed-off-by:

This IP block is found in the HDMI subsystem of the i.MX8MP SoC. It has a full timing generator and can switch between different video sources. On the i.MX8MP however the only supported source is the LCDIF. The block just needs to be powered up and told about the polarity of the video sync signals to act in bypass mode. Signed-off-by:

The cleanup can be dispatched while the atomic update is still active, which means that the memory acquired in the atomic update needs to not be invalidated by the cleanup. The buffer objects in vmw_plane_state instead of using the builtin map_and_cache were trying to handle the lifetime of the mapped memory themselves, leading to crashes. Use the map_and_cache instead of trying to manage the lifetime of the buffer objects held by the vmw_plane_state. Fixes kernel oops'es in IGT's kms_cursor_legacy forked-bo. Signed-off-by:

When a Loongson laptop is equipped with a Radeon GPU, it can be true that there is no dedicated VRAM soldered on the motherboard. This is probably for cost reason, but drm/loongson driver is probed because the platform BIOS (either UEFI or PMON) forget to disable the integrated GPU. So in the lsdc_get_dedicated_vram() function, we error out if no dedicated VRAM detected. This fix nothing, but serve as a sanity check only. Tested-by:

Some drivers require the mapped tt pages to be decrypted. In an ideal world this would have been handled by the dma layer, but the TTM page fault handling would have to be rewritten to able to do that. A side-effect of the TTM page fault handling is using a dma allocation per order (via ttm_pool_alloc_page) which makes it impossible to just trivially use dma_mmap_attrs. As a result ttm has to be very careful about trying to make its pgprot for the mapped tt pages match what the dma layer thinks it is. At the ttm layer it's possible to deduce the requirement to have tt pages decrypted by checking whether coherent dma allocations have been requested and the system is running with confidential computing technologies. This approach isn't ideal but keeping TTM matching DMAs expectations for the page properties is in general fragile, unfortunately proper fix would require a rewrite of TTM's page fault handling. Fixes vmwgfx with SEV enabled. v2: Explicitly include cc_platform.h v3: Use CC_ATTR_GUEST_MEM_ENCRYPT instead of CC_ATTR_MEM_ENCRYPT to limit the scope to guests and log when memory decryption is enabled.

vmw_context_cotable can return either an error or a null pointer and its usage sometimes went unchecked. Subsequent code would then try to access either a null pointer or an error value. The invalid dereferences were only possible with malformed userspace apps which never properly initialized the rendering contexts. Check the results of vmw_context_cotable to fix the invalid derefs.

Now the sii902x bridge is ready from DRM's perspective. - sii902x calls sii902x_audio_codec_init() and platform_device_register_data() - The registration of the audio platform device causes probing of the deferred devices. - tidss probes, which eventually causes sii902x_bridge_get_edid() to be called. - sii902x_bridge_get_edid() tries to use the i2c to read the edid. However, the sii902x driver has not set up the i2c part yet, leading to the crash. Fix this by moving the drm_bridge_add() to the end of the sii902x_init(), which is also at the very end of sii902x_probe(). Signed-off-by:

The synaptics-r63353 (panel-bridge) can only be configured in command mode. So, samsung-dsim (bridge) must not be in display mode during the prepare()/unprepare() of the panel-bridge. Setting the "pre_enable_prev_first" flag to true allows the prepare() of the panel-bridge to be called between the pre_enabled() and enabled() of the bridge. So, the bridge can enter display mode only in the enabled(). The unprepare() of the panel-bridge is instead called between the disable() and post_disable() of the bridge. So, the disable() must exit the display mode (i .e. enter command mode) to allow the panel-bridge to receive DSI commands. samsung_dsim_atomic_pre_enable -> command mode r63353_panel_prepare -> send DSI commands samsung_dsim_atomic_enable -> enter display mode samsung_dsim_atomic_disable -> exit display mode (command mode) r63353_panel_unprepare -> send DSI commands samsung_dsim_atomic_post_disable Co-developed-by:
