- Link to v6: https://lore.kernel.org/all/[e-mail]/

v6:
- Add bus type property in dt-binding which will be limited

  to make sure new platform driver can set CSID_PAYLOAD_MODE_DISABLED
  to disable TPG

- Link to v5: https://lore.kernel.org/all/[e-mail]/

v5:
- Update dt-bindings required items order - Krzysztof
- Sort the reg order based on the comments in sc7280 dt-binding - Vladimir
- Change the irq type to IRQ_TYPE_EDGE_RISING - Vladimir
- Remove the Krzysztof's RB tag from dt-binding patch due to above

  driver - Vladimir, Bryan
- Use a standalone patch for the callback API of RUP and buf done update
- Use a standalone patch to make CSID TPG optional - Vladimir
- Link to v4: https://lore.kernel.org/all/[e-mail]/

v4:
- Update dt-bindings based on comments - Krzysztof, bod, Vladimir
- Move common code into csid core and vfe core driver - bod
- Remove *_relaxed in the csid and vfe drivers - Krzysztof

and reg update - bod
- Remove custom code to get csid base - bod
- Remove ISR function in vfe780 driver since it is never fired - bod
- Move csid_top_base to camss structure since we only have one csid
top block, and just need to get base once for csid top
- Add Vladimir's RB
- Remove prerequisite-patch-id in the cover letter since the changes
have been merged
- Add dtsi patch link for reference - Krzysztof
https://lore.kernel.org/all/[e-mail]/
- Link to v3: https://lore.kernel.org/all/[e-mail]/

v3:
- Rebased the change based on below change which will be merged firstly.
"Move camss version related defs in to resources"
Link: https://lore.kernel.org/all/[e-mail]/
- Rebased the change based on Bryan's csiphy optimization change and add
these changes into this series, so that the new csiphy-3ph driver don't
need to add duplicate code. This has got Bryan's permission to add his
patches into this series.
- Refactor some changes based on the comments to move the random code to
patches where they are used.
- Remove the vfe780 irq function since it isn't doing the actual work.
- Add dt-binding for sm8550 camss driver.
