> Yes regmap & reg_field framework was something we evaluated before writing the driver initially as I was quite intrigued with the caching facility it provided for e.g. with regcache_sync_region we can restore the register context on resume, but this image encoder (similar to many other video codecs) did not require any caching of registers for suspend/resume and I did not want to go ahead with regmap/reg_field approach simply for updating fields as it goes through a layer of functions calls before reaching readl/write and these also involve some sort of locking too.
>
Locking is a good thing, how do you handle locking? I don't see
any register access exclusion in this driver. For instance
write_reg_field_not_busy() polls for a busy bit unset, then
does the write, what happens if another write makes it busy
again in-between? etc..
> Secondly, just to share, the current approach was much simpler to implement as the macro's present in e5010-core-regs.h and e5010-mmu-regs.h were shared by Imagination (possibly auto-generated).
>
I figured those are auto-generated given some of the definition names..
JASPER_CHROMA_QUANTIZATION_TABLE15_CR_CHROMA_QUANTIZATION_TABLE_74_MASK (!)
what is the point of these? Each table is 4 bytes from the last and each
mask is <<8 from the last, just calculate that when you use it. These definitions
are somehow worse than just using magic numbers. :/
All the more reason you should switch to regmap, makes you think about things
like that and make them more sane.

> I can get rid of one line helpers even now and call write_reg_field and write_reg_field_not_busy directly from *.c but the one line helpers (for e.g. e5010_hw_enable_picture_done_irq) were put deliberately from a design perspective to provide abstraction and simplicity as I wanted to keep all reg write stuff in *-hw.c, and provide a simple API for the driver to set stuff like width/height etc using a simple wrapper API without giving control to low-level reg access.

> This is similar to what is done in other codec drivers too [1] and I possibly don't see any of the codec drivers [2] utilizing regmap/reg_field approach so it doesn't seem to be a popular option or a mandatory thing either at least for the video codecs.
>
drivers/media has been around for a long time, not every driver is a good example
of current best practices. In fact one of your examples is more than a decade old
and predates regmap itself..
Plus, I *do* see media drivers using regmap and even regmap_field.
> To summarize for all the above reasons, I would personally prefer to stick to current approach, also the functions used in this approach (e5010-jpeg-enc-hw.c) were reviewed previously of which the comments were handled in this series, so I would like to hear from others too in case we want to change the approach.

You have had lots of other things to fix in each revision, having something
not be called out in the other 3 posting doesn't imply approval for it.
