This patchset introduces support for the technologic version of the
SJA1000. Access to IP's registers are proxied through a window,
requiring two bus accesses to read or write a register. These accesses
must be protected by a spinlock to prevent race conditions. Currently,
there is no easy way to allocate and initialize this spinlock.

SJA1000 already provides a way to allocate private data, but
sja1000_platform.c makes no use of it.

Patch 1 adds the capability to allocate and initialize private data on a
per-compatible basis in sja1000_platform.c.

Patch 2 updates device tree documentation to add the technologic
version.

Patch 3 updates the driver to implement the technologic version

Changes in v2:
 - added a patch to allocate and initialize private data
 - changed device tree documentation
 - added a spinlock to protect bus accesses
 - changed sp_{read,write}_reg16 to io{read,write}16

Damien Riegel (3):
  can: sja1000: of: add per-compatible init hook
  can: sja1000: add documentation for Technologic Systems version
  can: sja1000: of: add compatibility with Technologic Systems version
