Hello,
this patch series add support for the at91_can core on the upcoming
at91sam9x5 SOC series.
The original at91_can driver supports the at91sam9263 which has 16
mailboxes, but the CAN core on the at91sam9x5 has only 8. Most constants
used in the RX and TX path are derived from the number of mailboxes.
This patch series changes the driver from a static, compile time setup
of the mailboxes to a dynamic one. Patches 1-4 clean up the driver, 5+6
simplify the usage of the constants, patch 7 converts all derived constants
into functions. Patch 8 will add id_table support to the driver then all
remaining constants are converted into functions using the run time
selected mailbox constants. The next patch (9) takes care about an
at91sam9263 specific errata fix. Patch 10 and 11 will finally add supoprt
for the at91sam9x5 SOC.
This patch series applies to current net-next-2.6/master and has been tested
on a sam9263 and sam9x5ek.
(Allthough, the sam9x5 support is not mainline yet).
please review and consider to apply,
Marc
