ixp4xx_eth: make ptp support a platform driver

2021-08-30T08:59:11Z

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 98ac0cc270b7 ("ARM: ixp4xx: Convert to MULTI_IRQ_HANDLER") changed the IRQ number to something meaningless. Passing the correct IRQ in a resource fixes this. - When the PTP driver is disabled, ethtool .get_ts_info() now correctly lists only software timestamping regardless of the hardware.

ptp: ixp46x: move adjacent to ethernet driver

2020-01-12T20:59:52Z

The ixp46x ptp driver has a somewhat unusual setup, where the ptp driver and the ethernet driver are in different directories but access the same registers that are defined a platform specific header file. Moving everything into drivers/net/ makes it look more like most other ptp drivers and allows compile-testing this driver on other targets.
