From 6f0f6941624d6ded57d362e47e07f8ffe77fa394 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Fri, 7 Jul 2023 10:31:52 +0200 Subject: fbdev: Add fb_ops init macros for framebuffers in DMA-able memory Add initializer macros for struct fb_ops for framebuffers in DMA-able memory areas. Also add a corresponding Kconfig token. As of now, this is equivalent to system framebuffers and mostly useful for labeling drivers correctly. A later patch may add a generic DMA-specific mmap operation. Linux offers a number of dma_mmap_*() helpers for different use cases.
