DRA7 CAN IP suffers from a problem which causes it to be prevented from fully turning OFF (i.e. stuck in transition) if the module was disabled while there was traffic on the CAN_RX line. To work around this issue we select the SLEEP pin state by default on probe and use the DEFAULT pin state on CAN up and back to the SLEEP pin state on CAN down.

Some SoCs e.g. (TI DRA7xx) need a START pulse to start the RAMINIT sequence i.e. START bit must be set and cleared before checking for the DONE bit status. Signed-off-by: NRoger Quadros <rogerq@ti.com> Signed-off-by: NMarc Kleine-Budde <mkl@pengutronix.de>

Some TI SoCs like DRA7 have a RAMINIT register specification different from the other AMxx SoCs and as expected by the existing driver. To add more insanity, this register is shared with other IPs like DSS, PCIe and PWM. Provides a more generic mechanism to specify the RAMINIT register location and START/DONE bit position and use the syscon/regmap framework to access the register.

We want to have more data than just can_dev_id to be present in the driver data e.g. TI platforms need RAMINIT register description. Introduce the c_can_driver_data structure and move the can_dev_id into it. Tidy up the way it is used on probe().

TI's RAMINIT DONE mechanism is buggy on AM43xx SoC and may not always be set after the START bit is set. Although it seems to work fine even in that case. So add a timeout mechanism to c_can_hw_raminit_wait_ti(). Don't bail out in that failure case but just print an error message.

Eric Dumazet says: ==================== net: provide common RSS key infrastructure RSS (Receive Side Scaling) uses a 40 bytes key to provide hash for incoming packets to select appropriate incoming queue on NIC. Hash algo (Toeplitz) is also well known and documented by Microsoft (search for "Verifying the RSS Hash Calculation") Problem is that some drivers use a well known key. It makes very easy for attackers to target one particular RX queue, knowing that number of RX queues is a power of two, or at least some small number. Other drivers use a random value per port, making difficult tuning on bonding setups. Lets add a common infrastructure, so that host gets an unique RSS key, and drivers do not have to worry about this. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

RSS (Receive Side Scaling) typically uses Toeplitz hash and a 40 or 52 bytes RSS key. Some drivers use a constant (and well known key), some drivers use a random key per port, making bonding setups hard to tune. Well known keys increase attack surface, considering that number of queues is usually a power of two. This patch provides infrastructure to help drivers doing the right thing. netdev_rss_key_fill() should be used by drivers to initialize their RSS key, even if they provide ethtool -X support to let user redefine the key later. A new /proc/sys/net/core/netdev_rss_key file can be used to get the host RSS key even for drivers not providing ethtool -x support, in case some applications want to precisely setup flows to match some RX queues. Tested: myhost:~# cat /proc/sys/net/core/netdev_rss_key 11:63:99:bb:79:fb:a5:a7:07:45:b2:20:bf:02:42:2d:08:1a:dd:19:2b:6b:23:ac:56:28:9d:70:c3:ac:e8:16:4b:b7:c1:10:53:a4:78:41:36:40:74:b6:15:ca:27:44:aa:b3:4d:72 myhost:~# ethtool -x eth0 RX flow hash indirection table for eth0 with 8 RX ring(s): 0: 0 1 2 3 4 5 6 7 RSS hash key: 11:63:99:bb:79:fb:a5:a7:07:45:b2:20:bf:02:42:2d:08:1a:dd:19:2b:6b:23:ac:56:28:9d:70:c3:ac:e8:16:4b:b7:c1:10:53:a4:78:41 Signed-off-by: NEric Dumazet <edumazet@google.com> Signed-off-by: NDavid S.

This reverts commit e5a2c899. Commit e5a2c899 introduced an alternative_call, arch_fast_hash2, that selects between __jhash2 and __intel_crc4_2_hash based on the X86_FEATURE_XMM4_2. Unfortunately, the alternative_call system does not appear to be suitable for use with C functions, as register usage is not handled properly for the called functions. The __jhash2 function in particular clobbers registers that are not preserved when called via alternative_call, resulting in a panic for direct callers of arch_fast_hash2 on older CPUs lacking sse4_2. It is possible that __intel_crc4_2_hash works merely by chance because it uses fewer registers. This commit was suggested as the source of the problem by Jesse Gross <jesse@nicira.com>.
