Particularly discordant in this scheme is the subtle reliance on VFE and VFE Lite declaration ordering in our resources. VFE id is used to determine if a VFE is lite or not and consequently if a VFE requires power-domain attachment. VFE Lite though is not a correct delineation between power-domain and non power-domain state since early SoCs have neither VFE Lite nor power-domains attached to VFEs. Introduce has_pd to the VFE resource structure to allow the CAMSS code to understand if it needs to try to attach a power-domain for a given VFE. As a side-effect from this we no longer need to care about VFE Lite or non-Lite or the id number associated with either and which order the VFE/VFE Lite was declared in.

In effect this hard-codes VFE indexes to power-domain indexes in the dtsi and mandates a very particular ordering of power domains in the dtsi, which bears no relationship to a real hardware dependency. As a first step to rationalising the VFE power-domain code and breaking the magic indexing in dtsi use per-VFE pointers to genpd linkages. The top-level index in msm_vfe_subdev_init is still used to attain the initial so no functional or logical change arises from this change.

Not always done but applicable to all. - device_link_add (DL_FLAG_STATELESS | DL_FLAG_PM_RUNTIME | DL_FLAG_RPM_ACTIVE); - Error check returning -EINVAL on error. - Return 0 Reduce the pattern down to a common callback. VFE 4.1 is a special case which to me also indicates that it is worthwhile maintaining an indirection for the vfe_pm_domain_{on|off} for now. Otherwise lets chuck out a bunch of needlessly replicated code.

Separation of concerns and functional decomposition. vfe.c should be responsible for and know best how manage power-domains for a VFE, excising from camss.c follows this principle. 2. Embedding a pointer to genpd in struct camss_vfe{} meas that we can dispense with a bunch of kmalloc array inside of camss.c. 3. Splitting up titan top gdsc from vfe/ife gdsc provides a base for breaking up magic indexes in dtsi.

Adding support for named power-domains means the declaration in the dtsi can come in any order. After this change we continue to support the old indexing - if a SoC resource declaration or the in-use dtb doesn't declare power-domain names we fall back to the default legacy indexing. From this point on though new SoC additions should contain named power-domains, eventually we will drop support for legacy indexing.
