Subject: [PATCH v2 0/5] fbdev: Use regular I/O function for framebuffers
Date: Fri, 28 Apr 2023 11:27:06 +0200 [thread overview]
Message-ID: <20230428092711.406-1-tzimmermann@suse.de> (raw)
(was: fbdev: Move framebuffer I/O helpers to <asm/fb.h>)
Fbdev provides helpers for framebuffer I/O, such as fb_readl(),
fb_writel() or fb_memcpy_to_fb(). The implementation of each helper
depends on the architecture, but they all come down to regular I/O
functions of similar names. So use the regular functions instead.
The first patch a simple whitespace cleanup.
Until now, <linux/fb.h> contained an include of <asm/io.h>. As this
will go away patches 2 to 4 prepare include statements in the various
drivers. Source files that use regular I/O helpers, such as readl(),
now include <linux/io.h>. Source files that use framebuffer I/O
helpers, such as fb_readl(), also include <linux/io.h>.
Patch 5 replaces the architecture-based if-else branching in
<linux/fb.h> by define statements that map to Linux' I/O fucntions.
After this change has been merged and included in a few release
without complains, we can update the drivers to regular I/O functions
and remove the fbdev-specific defines.
The patchset has been built for a variety of platforms, such as x86-64,
arm, aarch64, ppc64, parisc, m64k, mips and sparc.
v2:
* use Linux I/O helpers (Sam, Arnd)
Thomas Zimmermann (5):
fbdev/matrox: Remove trailing whitespaces
ipu-v3: Include <linux/io.h>
fbdev: Include <linux/io.h> in various drivers
fbdev: Include <linux/io.h> in drivers
