fbdev: atyfb: only use ioremap_uc() on i386 and ia64

2023-11-08T13:08:57+00:00

[ Upstream commit c1a8d1d0edb71dec15c9649cb56866c71c1ecd9e ]

ioremap_uc() is only meaningful on old x86-32 systems with the PAT
extension, and on ia64 with its slightly unconventional ioremap()
behavior, everywhere else this is the same as ioremap() anyway.

Change the only driver that still references ioremap_uc() to only do so
on x86-32/ia64 in order to allow removing that interface at some
point in the future for the other architectures.

On some architectures, ioremap_uc() just returns NULL, changing
the driver to call ioremap() means that they now have a chance
of working correctly.

fbdev: atyfb: Remove unused clock determination

2023-05-20T05:02:12+00:00

Just below the removed lines par->clk_wr_offset is hard coded to 3 so
there is no use in determining a different clock just to then ignore it
anyway. This also removes the only I/O port use remaining in the driver
allowing it to be built without CONFIG_HAS_IOPORT.

fbdev: Rename fb_mem*() helpers

2023-05-18T09:07:54+00:00

Update the names of the fb_mem*() helpers to be consistent with their
regular counterparts. Hence, fb_memset() now becomes fb_memset_io(),
fb_memcpy_fromfb() now becomes fb_memcpy_fromio() and fb_memcpy_tofb()
becomes fb_memcpy_toio(). No functional changes.

v6:
	* update new file fb_io_fops.c

fbdev/radeon: use pci aperture helpers

2023-04-04T12:55:58+00:00

It's not exactly the same since the open coded version doesn't set
primary correctly. But that's a bugfix, so shouldn't hurt really.

fbdev: radeon: Use backlight helper

2023-01-09T08:57:50+00:00

Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all
this and insulates this from future changes.

The implementation of strscpy() is more robust and safer.
That's now the recommended way to copy NUL-terminated strings.
