V3: - Adds RB/AB as indicated - Konrad - Replaces >= SDM845 with helper function per discussion - bod/Konrad - Leaves out constraining VFE clock names sizes. A full pass for resource strings will happen later. - bod - Clarifies commit log resulting in updated patch title also "Add support for setting CSIPHY clock name csiphyX" -> "Fix support for setting CSIPHY clock name csiphyX" - Adds patch to remove dead integer return type in vfe_disable() - Adds patch to comment CSID dt_id meanining which I personally find non-obvious right now - bod Link: https://git.codelinaro.org/bryan.odonoghue/kernel/-/commits/09e7805a733b488c5dc19b301eb3b77cb0fad3d6 V2: - Replaces &camss->res with pointer to res - Konrad - Squashes patch for NULL removal - Konrad - Left suggestion on ICC initialisation points alone, doesn't seem to fit Konrad/bod Link: https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/linux-next-23-08-07-db410c-rb3-camss-dts-v3+maintenance-bugfixes-v2 V1: - I forgot to include patch # 14 in V0 of this series. This patch leverages previous changes to unwind the fixed polling of RDI[0..2] allowing driver data to articulate on a per-VFE basis how many RDIs to poll. Link: https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/linux-next-23-08-07-db410c-rb3-camss-dts-v3+maintenance-bugfixes-v1 V0: This second series of bugfixes stacks ontop of the Fixes series sent earlier. Link: https://lore.kernel.org/linux-arm-msm/20230814141007.3721197-1-bryan.odonoghue@xxxxxxxxxx/T/#t Rather than send both series as one giant series, I opted to send a pure Fixes series above, with this second series a non-backport series i.e. no Fixes tags in this series. The existing CAMSS code relies on some hard-coded parameters buried inside of the driver, instead of passed via compat .data as arguably ought to be the case. This brittle model is an extending morass of spaghetti code. More than that in CAMSS Video Front Ends (VFEs) and the number of Raw Data Interfaces (RDIs) per VFE can vary from SoC to SoC. Indeed sm8250 has VFE and VFE Lite blocks which have a different number of RDIs per block. The use of defines as opposed to per-compat parameters inside of ISRs leads to either under-polling or over-polling the number of RDIs. On top of all of that we have some hard-coded statements for clock names which breaks easily. We can solve the under/over polling loop problem by transitioning loop controls from macros to parameters passed via probe(). Similarly and unsurprisingly we can also solve the hard-coded clock problem by adding some string processing routines that take passed arguments. There is still some additional maintenance work to be done in this driver but before adding one more SoC the code needs to be made more extensible and less brittle.
