  Well, like I said, I'd rather see the CLK_OF_DECLARE stuff be
  made to work on PPC rather than have the driver carry around
  two binding methods.

 I guess that is an existing problem, and not related directly to
 this patch? This patch is essentially just renames (though the
 V1.0/V2.0 stuff seems weird).
   
This patch is adding CLK_OF_DECLARE.
  
   I'm fine taking this patch but your comments are still unresolved.
   What do you think needs to be done to fix the problems that you see?
  
  CLK_OF_DECLARE is totally worked on PPC. I will do it in a separate patch.
  Regarding V1.0 and V2.0, it is not wired just same for now. But we are not 
  sure
 if it is same for v3.0 in the future.
 
  Besides updating drivers/cpufreq/Kconfig.powerpc, there is one more thing I
 am not comfortable with:
  This patch uses  fixed-clock as sysclk's compatible string, while on PPC 
  we
 treated it as  fsl,qoriq-sysclk-[1-2].0.
  That's inconsistent on both ARM and PPC platforms, neither did on bindings.
 
 fsl,qoriq-sysclk-XXX is the way it is because of compatibility with the 
 fixups in
 existing U-Boots.  It shouldn't be used as a model.
 
 That said, I don't think you really mean this patch, as it doesn't contain 
 the
 device tree updates, and fixed-clock does not appear.
 
fixed-clock will appear when ls102x platform DTS gets upstreamed eventually.
That would be fine if you don't think fsl,qoriq-sysclk-xxx having different 
meaning on ARM and PowerPC is a issue.

Thanks,
Yuantian

I think you need to also update drivers/cpufreq/Kconfig.powerpc to use the
renamed config option.


Thanks, I will update that selected config option of CLK_PPC_CORENET.

Re: [PATCHv4] clk: ppc-corenet: rename to ppc-qoriq and add CLK_OF_DECLARE support

2014-09-25 Thread Mike Turquette
Quoting Scott Wood (2014-09-25 13:08:00)
 Well, like I said, I'd rather see the CLK_OF_DECLARE stuff be made to
 work on PPC rather than have the driver carry around two binding
 methods.

I guess that is an existing problem, and not related directly to this
patch? This patch is essentially just renames (though the V1.0/V2.0
stuff seems weird).

Regards,
Mike

  Subject: [PATCHv4] clk: ppc-corenet: rename to ppc-qoriq and add
  CLK_OF_DECLARE support
  
  The IP is shared by PPC and ARM, this renames it to qoriq for better
  represention, and this also adds the CLK_OF_DECLARE support for being
  initialized by of_clk_init() on ARM.

  changes in v4:
   remove corenet literals omitted in v3 remove.
  
  changes in v3:
   generate the patch with -M -C option
  
  changes in v2:
   rename the driver name to ppc-qoriq.c for shared on PPC and ARM.
