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 v6:
- fix static const struct of_device_id sp_of_table
Changes in v5:
- remove empty "static struct sja1000_of_data nxp_data", again
- add additional check for of_id->data
Changes in v4:
- add sp_ prefix to technologic functions
- add empty "static struct sja1000_of_data nxp_data"
- make "struct sja1000_of_data technologic_data" static
- get rid of "?" operator in sp_probe()
Changes in v3:
- moved sp_of_table above sp_probe as it is used in this function
- removed functions added in v2 and do everyting in sp_probe
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
