csid_isr() only checks for the reset irq, so enabling any other irqs
doesn't make sense. The "RDI irq" comment is also wrong, the register
should be CSID_CSI2_RDIN_IRQ_MASK. Without this fix there may be an
excessive amount of irqs.

This is a leftover from my original patches, it doesn't serve any purpose.
(it was a reminder to figure out how downstream sets a particular field in
the register).

Use the "HALT_CMD_RESUME_AT_FRAME_BOUNDARY" define instead of a "1" which
is otherwise confusing, and add a "HALT_CMD_HALT_AT_FRAME_BOUNDARY" which
is set when disabling.

This isn't used and only works because devm_regulator_get() returns a dummy
regulator.

Delete vfe_isr_ops. In all cases the right function can just be called
directly.
From vfe_hw_ops:
- enable_irq_common is completely dead
- isr_read/violation_read dont need ops (call right function directly)
- reg_update/reg_update_clear moved to gen1 ops, vfe-170 can call the
right function directly
This reveals dead function in vfe-170 which are deleted. comp_done IRQ
handling is also removed for vfe-170 - only RDI is supported.

This function waits for halt_complete but doesn't do anything to cause
it to complete, and always hits the "VFE halt timeout" error. Just delete
this code for now.

Add support for VFE found on SM8250 (Titan 480). This implementation is
based on the titan 170 implementation. It supports the normal and lite VFE,
and only supports the RDI0 capture path.

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.

Move these before ports. (DT) properties first then nodes.

Should be separate phy nodes? Same/similar DPHY or CPHY as QCom DSI PHY?

This is not a new driver, this series only adds support for a new SoC -
the design has already been decided (and this binding is similar to
qcom,sdm845-camss.yaml).
The hardware supports D-PHY and C-PHY, but the driver isn't aware of
this and assumes D-PHY. sdm845 and msm8996 hardware also support C-PHY,
so it isn't a problem specific to this series.

Hi Jonathan,
I've given this patchset a try on RB3 board (SDM845) with ov8856 camera sensor - works OK,
no regressions.
Thanks,
Andrey
