2024-12-13drm: Drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König
These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

2024-12-10drm/bridge/synopsys: Add MIPI DSI2 host controller bridgeHeiko Stuebner
Add a Synopsys Designware MIPI DSI host DRM bridge driver for their DSI2 host controller, based on the Rockchip version from the driver rockchip/dw-mipi-dsi2.c in their vendor-kernel with phy & bridge APIs. While the driver is heavily modelled after the previous IP, the register set of this DSI2 controller is completely different and there are also additional properties like the variable-width phy interface.

2024-12-10drm/log: Add integer scaling supportJocelyn Falempe
Add a module parameter, to increase the font size for HiDPI screen. Even with CONFIG_FONT_TER16x32, it can still be a bit small to read. In this case, adding drm_log.scale=2 to your kernel command line will double the character size.

2024-12-10drm/log: Implement suspend/resumeJocelyn Falempe
Normally the console is already suspended when the graphic driver suspend callback is called, but if the parameter no_console_suspend is set, it might still be active. So call console_stop()/console_start() in the suspend/resume callbacks, to make sure it won't try to write to the framebuffer while the graphic driver is suspended.

2024-12-10drm/log: Do not draw if drm_master is takenJocelyn Falempe
When userspace takes drm_master, the drm_client buffer is no more visible, so drm_log shouldn't waste CPU cycle to draw on it.

2024-12-10drm/log: Introduce a new boot logger to draw the kmsg on the screenJocelyn Falempe
drm_log is a simple logger that uses the drm_client API to print the kmsg boot log on the screen. This is not a full replacement to fbcon, as it will only print the kmsg. It will never handle user input, or a terminal because this is better done in userspace. Design decisions: * It uses the drm_client API, so it should work on all drm drivers from the start. * It doesn't scroll the message, that way it doesn't need to redraw the whole screen for each new message. It also means it doesn't have to keep drawn messages in memory, to redraw them when scrolling. * It uses the new non-blocking console API, so it should work well with PREEMPT_RT. This patch also adds a Kconfig menu to select the drm client to use. It can be overwritten on the kernel command line with: drm_client_lib.active=log or drm_client_lib.active=fbdev Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com> Reviewed-by: John Ogness <john.ogness@linutronix.de> # console API Reviewed-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20241204160014.1171469-3-jfalempe@redhat.com
