During board bringups its useful to have a DSI test pattern
generator to isolate a DPU vs a DSI issue and focus on the relevant
hardware block.
To facilitate this, add an API which triggers the DSI controller
test pattern. The expected output is a rectangular checkered pattern.
This has been
Some bootloaders set the widebus enable bit in the INTF_CONFIG register,
but configuration of widebus isn't yet supported ensure that the
register has a known value, with widebus disabled.

Not all platforms has P0 at an offset of 0x1000 from the base address,
so add support for specifying each sub-region in DT. The code falls back
to the predefined offsets in the case that only a single reg is
specified, in order to support existing DT.

In order to deal with multiple memory ranges in the following commit
change the ioremap wrapper to not poke directly into the dss_io_data

Not all platforms has DP_P0 at offset 0x1000 from the beginning of the
DP block. So dss_io_data into representing each of the sub-regions, to
make it possible in the next patch to specify each of the sub-regions
individually.

The non-devres version of ioremap is used, which requires manual
cleanup. But the code paths leading here is mixed with other devres
users, so rely on this for ioremap as well to simplify the code.

reg was defined as one region covering the entire DP block, but the
memory map is actually split in 4 regions and obviously the size of
these regions differs between platforms.
Switch the reg to require that all four regions are specified instead.
It is expected that the implementation will
It turns out that sc8180x (among others) doesn't have the same internal layout
of the 4 subblocks. This series therefor modifies the binding to require all
four regions to be described individually and then extends the driver to read
these four regions. The driver will fall back to read the old
