2022-07-18net: stmmac: switch to use interrupt for hw crosstimestampingWong Vee Khee
Using current implementation of polling mode, there is high chances we will hit into timeout error when running phc2sys. Hence, update the implementation of hardware crosstimestamping to use the MAC interrupt service routine instead of polling for TSIS bit in the MAC Timestamp Interrupt Status register to be set.

The blamed commit introduce support for lan966x which use the same pinconf_ops as sparx5. The problem is that pinconf_ops is specific to sparx5. More precisely the offset of the bits in the pincfg register are different and also lan966x doesn't have support for PIN_CONFIG_INPUT_SCHMITT_ENABLE. Fix this by making pinconf_ops more generic such that it can be also used by lan966x. This is done by introducing 'ocelot_pincfg_data' which contains the offset and what is supported for each SOC.

The CSI receiver is a component separate from the ISP or the resizers. It is actually optional, not all device model include a CSI receiver. On some SoCs CSI-2 support can be provided through an external CSI-2 receiver, connected to the ISP's parallel input. To support those use cases, create a V4L2 subdev to model the CSI receiver.

The ISP supports multiple source subdevs, but can only capture from a single one at a time. The source is selected through link setup. The driver finds the active source in its .s_stream() handler using the media_entity_remote_pad() function. This fails to reject invalid configurations with multiple active sources. Fix it by using the media_pad_remote_pad_unique() helper instead, and inline rkisp1_isp_get_source() in rkisp1_isp_s_stream() as the function is small and has a single caller.
