media: qcom: camss: Flag CSID-lites to support more CSIDs Some platforms such as SC7280 have 3 CSIDs and 2 CSID-lites but current code has hardcoded 2 as the maximum number of CSIDs. Remove the hardcoded maximum number of VFEs to handle all possible combinations of CSIDs and CSID-lites.

We represent these blocks as v4l subdevices. The name "struct camss_subdev_resources" is a more descriptive and accurate name.

media: camss: sm8250: Virtual channels for CSID CSID hardware on SM8250 can demux up to 4 simultaneous streams based on virtual channel (vc) or datatype (dt). The CSID subdevice entity now has 4 source ports that can be enabled/disabled and thus can control which virtual channels are enabled. Datatype demuxing not tested. In order to keep a valid internal state of the subdevice, implicit format propagation from the sink to the source pads has been preserved. However, the format on each source pad can be different and in that case it must be configured explicitly. CSID's s_stream is called when any stream is started or stopped. It will call configure_streams() that will rewrite IRQ settings to HW. When multiple streams are running simultaneously there is an issue when writing IRQ settings for one stream while another is still running, thus avoid re-writing settings if they were not changed in link setup, or by fully powering off the CSID hardware.

media: camss: Add regulator_bulk support Add the ability to enable or disable multiple regulators in bulk with camss. This is useful for sm8250, sdm845 and it looks like sdm660 where we have more than one CSI regulator to do at once. It should just work for standalone existing vdda regulators and parts which don't have an explicitly defined CSI regulator.

media: camss: add support for SM8250 camss The Titan 480 camss found on SM8250 has 6 CSIPHY and 4 VFE/CSID. CSID is compatible with the Titan 170 CSID, but the Titan 480 CSID are inside the VFE region (between the "top" and "bus" registers), so a workaround is added to avoid ioremap failure.

media: camss: Add missing format identifiers The CSI-2 spec defines format identifier for Data Type (DT), and how the Decode Format (DF) & Encode Format (EF) are implemented. The spec does however not define the DF, EF or Plain Format (PF) identifiers, as those are vendor specific. Plain formats describe the size of the pixels written by the RDI units to memory. PLAIN8 for example has the size 8 bits, and PLAIN32 32 bits. The appropriate Plain Format is determined by the Decode Format used. The smallest Plain Format that is able to contain a pixel of the used Decode Format is the appropriate one to use. As the vendor specific identifiers differ between hardware generations, split them out into separate headers.
