0be4b0b651 reset: Return 0 if ops unimplemented and remove empty functions
In case the ops is not implemented, return 0 in the core right away.
This is better than having multiple copies of functions which just
return 0 in each reset driver. Drop all those empty functions.

f10643cf8a dm: core: Access device ofnode through functions
At present ofnode is present in the device even if it is never used. With
of-platdata this field is not used, so can be removed. In preparation for
this, change the access to go through inline functions.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

702e57e113 treewide: convert devfdt_get_addr_ptr() to dev_read_addr_ptr()
When you enable CONFIG_OF_LIVE, you will end up with a lot of
conversions.

To help this tedious work, this commit converts devfdt_get_addr_ptr()
to dev_read_addr_ptr() by coccinelle. I also removed redundant casts
because dev_read_addr_ptr() returns an opaque pointer.

To generate this commit, I ran the following semantic patch
excluding include/dm/.

  <smpl>

  type T;
  expression dev;

  -(T *)devfdt_get_addr_ptr(dev)
  +dev_read_addr_ptr(dev)

336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

9e6082198a reset: socfpga: Poll for reset status after deassert reset
In Cyclone 5 SoC platform, the first USB probing is failed but second
probing is success. DWC2 USB driver read gsnpsid register right after
de-assert reset, but controller is not ready yet and it returns gsnpsid 0.
Polling reset status after de-assert reset to solve the issue.

Retry with this fix more than 10 times without issue.

ef72ba0b87 sysreset: add support for socfpga sysreset
This moves sysreset support for socfgpa from ad-hoc code in mach-socfpga
to a UCLASS_SYSRESET based dm driver.

A side effect is that gen5 and a10 can now select between cold and warm
reset.

ede6e7b64f reset: socfpga: add reset handling for old kernels
This adds code to take peripherals out of reset based on an environment
variable. This is in preparation for removing the code that does this from
SPL.

However, some drivers even in current Linux cannot handle peripheral reset,
so until this works, we need a compatibility workaround.

This workaround is implemented in the 'assert' and 'remove' callbacks of
this reset driver: the 'assert' callback does not disable peripherals that
were already taken out of reset, while the 'remove' callback, which is
called on OS_PREPARE, deasserts all peripheral resets if the environment
variable "socfpga_legacy_reset_compat" is set to 1, which is what the gen5
SPL did up to now.

This is in preparation to clean up the SPL and implementing proper reset
handling for U-Boot.

1ea975010d reset: socfpga: rename membase ptr to modrst_base
The only member of this driver's priv struct is a pointer, which is
called 'membase'. However, since this driver handles multiple sub-
architectures, this is not the base address from dts but the base
address of some common registers of those sub-arches.

Reflect this better in sourcecode by renaming 'membase' to 'modrst_base'.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.
