can: pch_can: fix error passive level test

2012-02-02T23:25:22+00:00

The test (((errc & PCH_REC) >> 8) > 127) would always be false because
the receive error counter ((errc & PCH_REC) >> 8) is at most 127, where
PCH_REC is defined as 0x7f00.  To test whether the receive error counter
has reached the error passive level, the RP bit (15) should be used.

pch_can: fix tseg1/tseg2 setting issue

2011-02-10T00:46:21+00:00

Previous patch "[PATCH 1/3] pch_can: fix 800k comms issue" is wrong.
I should have modified tseg1_min not tseg2_min.
This patch reverts tseg2_min to 1 and set tseg1_min to 2.

The cause is bus-master is not set in pch_can.
Thus, add enabling bus-master processing.

pch_can: fix rmmod issue

2011-02-09T00:37:19+00:00

Currently, when rmmod pch_can, kernel failure occurs.
The cause is pci_iounmap executed before pch_can_reset.
Thus pci_iounmap moves after pch_can_reset.

pch_can: fix 800k comms issue

2011-02-09T00:37:19+00:00

Currently, 800k comms fails since prop_seg set zero.
(EG20T PCH CAN register of prop_seg must be set more than 1)
To prevent prop_seg set to zero, change tseg2_min 1 to 2.

Since this driver is implemented as NAPI,
