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 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
