Due to a reversed dependency, it is possible to build
the lower ptp driver as a loadable module and the actual
driver using it as built-in, causing a link error:

Change the Makefile logic to always build the ptp module
the same way as the rest. Another option would be to
just add it to the same module and remove the exports,
but I don't know if there was a good reason to keep them
separate.

This is the driver for the NXP SJA1105 automotive Ethernet switch
|
|
family. These are 5-port devices and are managed over an SPI
|
|
interface. Probing is handled based on OF bindings and so is the
|
|
linkage to PHYLINK. The driver supports the following revisions:
|
|
- SJA1105E (Gen. 1, No TT-Ethernet)
|
|
- SJA1105T (Gen. 1, TT-Ethernet)
|
|
- SJA1105P (Gen. 2, No SGMII, No TT-Ethernet)
|
|
- SJA1105Q (Gen. 2, No SGMII, TT-Ethernet)
|
|
- SJA1105R (Gen. 2, SGMII, No TT-Ethernet)
|
|
- SJA1105S (Gen. 2, SGMII, TT-Ethernet)

This enables support for timestamping and PTP clock manipulations in
|

the SJA1105 DSA driver.
