7a73465e4c fbdev/clps711x-fb: Do not set struct fb_info.apertures
Generic fbdev drivers use the apertures field in struct fb_info to
control ownership of the framebuffer memory and graphics device. Do
not set the values in clps711x-fb.

8d0268585b fbdev: Move fbdev drivers from strlcpy to strscpy
Follow the advice of the below link and prefer 'strscpy' in this
subsystem. Conversion is 1:1 because the return value is not used.

6fbe0cc53a video: fbdev: clps711x-fb: Use syscon_regmap_lookup_by_phandle
Since version 5.13, the standard syscon bindings have been added
to all clps711x DT nodes, so we can now use the more general
syscon_regmap_lookup_by_phandle function to get the syscon pointer.

8a48ac3393 video: constify fb ops across all drivers
Now that the fbops member of struct fb_info is const, we can start
making the ops const as well.

This does not cover all drivers; some actually modify the fbops struct,
for example to adjust for different configurations, and others do more
involved things that I'd rather not touch in practically obsolete
drivers. Mostly this is the low hanging fruit where we can add "const"
and be done with it.

v3:
- un-constify atyfb, mb862xx, nvidia and uvesabf (0day)

v2:
- fix typo (Christophe de Dinechin)
- use "static const" instead of "const static" in mx3fb.c
- also constify smscufx.c

supported chip (EP7209). Since the DT-support for this CPU is not yet
announced, this change is safe.

Logic CLPS711X CPUs.
FB features:
- 1-2-4 bits per pixel.
- Programmable panel size to a maximum of 1024x256 at 4 bps.
- Relocatible Frame Buffer (SRAM or SDRAM).
- Programmable refresh rates.
- 16 gray scale values.
This new driver is designed to usage with devicetree only.
The driver have been tested with custom board equipped
Cirrus Logic EP7312.
