Subject: [PATCH v2 0/3] can: sja1000: support for technologic version
Date: Thu, 24 Dec 2015 12:42:50 -0500 [thread overview]
Message-ID: <1450978973-30417-1-git-send-email-damien.riegel@savoirfairelinux.com> (raw)
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
