* ixgbe: implement support for SDP/PPS output on X550 hardwareJacob Keller2019-06-051-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | Similar to the X540 hardware, enable support for generating a 1pps output signal on SDP0. This support is slightly different to the X540 hardware, because of the register layout changes. First, the system time register is now represented in 'cycles' and 'billions of cycles'. Second, we need to also program the TSSDP register, as well as the ESDP register. Third, the clock output uses only FREQOUT, instead of a full 64bit value for the output clock period. Finally, we have to use the ST0 bit instead of the SYNCLK bit in the TSAUXC register. This support should work even for the hardware with a higher frequency clock, as it carefully takes into account the multiply and shift of the cycle counter used. We also set the pps configuration to 1, since we now support generating a pulse per second output.

Then it makes use of those definitions to test for if IPsec has been disabled on the part and if so we do not enable it.

* ixgbe: use link instead of I2C combined abstractionEmil Tantilov2016-11-051-6/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce ixgbe_link_operations struct with the following changes: read_i2c_combined => read_link read_i2c_combined_unlocked => read_link_unlocked write_i2c_combined => write_link write_i2c_combined_unlocked => write_link_unlocked This will allow X550EM_a to override these methods for MDIO access while X550EM_x provides methods to use I2C combined access. This also adds a new structure, ixgbe_link_info, to hold information about the link. Initially this is just method pointers and a bus address. The functions involved in combined I2C accesses were moved from ixgbe_phy.c to ixgbe_x550.c. The underlying functions that carry out the combined I2C accesses were left in ixgbe_phy.c because they share some functions with other I2C methods. v2 - set hw->link.ops in probe. v3 - check ii->link_ops before setting it since we don't have it for all devices.

With the impending release of GCC 6 and its associated new warnings, some usages such as (1 << 31) have been noted within the ixgbe driver source. Fix these wholesale and prevent future issues by simply using BIT macro instead of hand coded bit shifts. Also fix a few shifts that are shifting values into place by using the 'u' prefix to indicate unsigned. It doesn't strictly matter in these cases because we're not shifting by too large a value, but these are all unsigned values and should be indicated as such.
