After the recent ixp4xx cleanups, the ptp driver has gained a
build failure in some configurations:
drivers/net/ethernet/xscale/ptp_ixp46x.c: In function 'ptp_ixp_init':
drivers/net/ethernet/xscale/ptp_ixp46x.c:290:51: error: 'IXP4XX_TIMESYNC_BASE_VIRT' undeclared (first use in this function)
Avoid the last bit of hardcoded constants from platform headers
by turning the ptp driver bit into a platform driver and passing
the IRQ and MMIO address as resources.
This is a bit tricky:
- The interface between the two drivers is now the new
ixp46x_ptp_find() function, replacing the global
ixp46x_phc_index variable. The call is done as late
as possible, in hwtstamp_set(), to ensure that the
ptp device is fully probed.
- As the ptp driver is now called by the network driver, the
link dependency is reversed, which in turn requires a small
Makefile hack
- The GPIO number is still left hardcoded. This is clearly not
great, but it can be addressed later. Note that commit
