Initialize the instance of struct fb_ops with fbdev initializer macros for framebuffers in I/O address space. Set the read/write, draw and mmap callbacks to the correct implementation and avoid implicit defaults. Also select the necessary I/O helpers in Kconfig. Fbdev drivers sometimes rely on the callbacks being NULL for a default implementation to be invoked; hence requiring the I/O helpers to be built in any case. Setting all callbacks in all drivers explicitly will allow to make the I/O helpers optional. This benefits systems that do not use these functions. No functional changes. Signed-off-by:

Provide helpers for accessing I/O memory in a helper module. The fbdev core uses these helpers, so select the module unconditionally for fbdev. Drivers will later be able to select the module individually and the helpers will become optional. Signed-off-by:

There are DT properties that can be shared across different Solomon OLED Display Controller families. Split them into a separate common schema to avoid these properties to be duplicated in different DT bindings schemas. Suggested-by:

The Solomon SSD132x controllers (such as the SSD1322, SSD1325 and SSD1327) are used by 16 grayscale dot matrix OLED panels, extend the driver to also support this chip family. Instead adding an indirection level to allow the same modesetting pipeline to be used by both controller families, add another pipeline for SSD132x. This leads to some code duplication but it makes the driver easier to read and reason about. Once other controller families are added (e.g: SSD133x), some common code can be factored out in driver helpers to be shared by the different families. But that can be done later once these patterns emerge. Signed-off-by:

This deemed useful to avoid hardcoding a page height and allow to support other Solomon controller families, but dividing the screen in pages seems to be something that is specific to the SSD130x chip family. For example, SSD132x chip family divides the screen in segments (columns) and common outputs (rows), so the concept of screen pages does not exist for the SSD132x family. Let's drop this field from the device info struct and just use a constant SSD130X_PAGE_HEIGHT macro to define the page height. While being there, replace hardcoded 8 values in places where it is used as the page height. Signed-off-by:

Dual-licence in order to make it possible for other non-GPL os'es to re-implement the code. The use of EXPORT_SYMBOL_GPL() is intentionally left untouched to prevent use of drm_gpuvm as a proxy for non-GPL drivers to access GPL-only kernel symbols. Much of the ideas and algorithms used in the drm_gpuvm code is already present in one way or another in MIT-licensed code.
