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.

As pointed out by Reuben Dowle and Lothar Waßmann, the TWRN_INT, RWRN_INT, BOFF_INT interrupt sources need to be cleared as well to avoid interrupt flooding, at least for the Flexcan on i.MX28 SOCs. Furthermore, the interrupts are only cleared, if really one of those interrupt sources are pending (which is not the case for rx and tx done).

module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. (Thanks to Joe Perches for suggesting coccinelle for 0/1 -> true/false). Cc: "David S.

This patch adds support for legacy Bosch CC770 and Intel AN82527 CAN controllers on the ISA or PC-104 bus. The I/O port or memory address and the IRQ number must be specified via module parameters: insmod cc770_isa.ko port=0x310,0x380 irq=7,11 for ISA devices using I/O ports or: insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 for memory mapped ISA devices. Indirect access via address and data port is supported as well: insmod cc770_isa.ko port=0x310,0x380 indirect=1 irq=7,11 Furthermore, the following mode parameter can be defined: clk: External oscillator clock frequency (default=16000000 [16 MHz]) cir: CPU interface register (default=0x40 [DSC]) bcr: Bus configuration register (default=0x40 [CBY]) cor: Clockout register (default=0x00) Note: for clk, cir, bcr and cor, the first argument re-defines the default for all other devices, e.g.: insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000 is equivalent to insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000,24000000 Signed-off-by: NWolfgang Grandegger <wg@grandegger.com> Acked-by: NMarc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: NDavid S.

This patch adds support for SJW user settings to not set the synchronization jump width (SJW) to 1 in any case when using the in-kernel bittiming calculation. The ip-tool from iproute2 already supports to pass the user defined SJW value. The given SJW value is sanitized with the controller specific sjw_max and the calculated tseg2 value. As the SJW can have values up to 4 providing this value will lead to the maximum possible SJW automatically. A higher SJW allows higher controller oscillator tolerances.

由 Julia Lawall 提交于
In this code, the failure_cleanup label calls the function plx_pci_del_card, which frees everything in the card->net_dev array. dev is placed in this array immediately after allocation, so the two subsequent jumps to failure_cleanup should not also call free_sja1000dev, but the second one does. If plx_pci_check_sja1000 fails, then free_sja1000dev is also called on dev. Because dev is already in the card->net_dev array, this implies that when plx_pci_del_card is later called, it may get freed again. So that entry is reset to NULL after the free. Finally, if there is a problem with one channel, there will be a hole in the array. card->channels counts the number of channels that have succeeded, and does not keep track of the index of the largest element in the array that is valid. So the loop in plx_pci_del_card is changed to go up to PLX_PCI_MAX_CHAN, which is only 2. Signed-off-by: NJulia Lawall <julia@diku.dk> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
