2023-07-22fbdev: Split frame buffer support in FB and FB_CORE symbolsJavier Martinez Canillas5-23/+35
Currently the CONFIG_FB option has to be enabled even if no legacy fbdev drivers are needed (e.g: only to have support for framebuffer consoles). The DRM subsystem has a fbdev emulation layer, but depends on CONFIG_FB and so it can only be enabled if that dependency is enabled as well. That means fbdev drivers have to be explicitly disabled if users want to enable CONFIG_FB, only to use fbcon and/or the DRM fbdev emulation layer. This patch introduces a non-visible CONFIG_FB_CORE symbol that could be enabled just to have core support needed for CONFIG_DRM_FBDEV_EMULATION, allowing CONFIG_FB to be disabled (and automatically disabling all the fbdev drivers). Nothing from fb_backlight.o and fbmon.o is used by the DRM fbdev emulation layer so these two objects can be compiled out when CONFIG_FB is disabled.

2023-07-20fbdev: Explicitly include correct DT includesRob Herring18-26/+31
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-07-08fbdev/ssd1307fb: Generate deferred I/O opsThomas Zimmermann1-58/+11
Use the existing generator macros to create deferred-I/O helpers for ssd1307fb and set them in the fb_ops structure. Functions for damage handling on memory ranges and areas are provided by the driver. Ssd1307fb's implementation of fb_write writes to system memory, so the generated code can use the respective helper internally. This also fixes a long-standing bug where fb_write returned an errno code instead of the number of written bytes.

2023-06-30sticon/parisc: Fix STI console on 64-bit only machinesHelge Deller2-57/+106
Fix the STI console to be able to execute either the 64-bit STI ROM code or the 32-bit STI ROM code. This is necessary on 64-bit only machines (e.g. C8000 workstation) which otherwise won't show the STI text console with HP graphic cards like Visualize-FX5/FX10/FXe. Note that when calling 32-bit code from a 64-bit kernel one needs to copy contents on the CPU stack from high memory down below the 4GB limit.
