These patches is not about changing naming conventions. Only changes, necessary to have a clean and consistent namespace after integrating PCM driver, have been made.
Agree, but you already are changing the prefix from s3c24xx to s3c.
I also agree with this - if we're renaming this driver anyway then changing the prefix for it while we're at it seems reasonable, it means one less change in the future.
renaming is a box of worms which i dont wanna be the first to open. I would wait for a complete discussion on the naming conventions to happen and have a decision made before I do renaming. Though, I can resend the patch with samsung_ prefix too, if everyone is willing to hold their peace forever.
but if we try so, we have the following
- s3c24xx_pcm_dma_params -> s3c_dma_dma_params
- s3c24xx_pcm_preallocate_dma_buffer -> s3c_dma_preallocate_dma_buffer
- s3c24xx_pcm_dmamask -> s3c_dma_dmamask
none of which seem very nice.
You can modify the names for the consistent prefix. If you use s3c_dma_ prefix, for example, s3c24xx_pcm_dma_params can be to s3c_dma_params.
I tend to agree with this. The actual rename needs to happen to free up the PCM name for the driver for the PCM hardware.
So taking into account the aforementioned point as well, you suggest
- s3c24xx_pcm_dma_params -> samsung_dma_params
- s3c24xx_pcm_preallocate_dma_buffer -> samsung_preallocate_dma_buffer
- s3c24xx_pcm_dmamask -> samsung_dmamask
- s3c24xx_pcm_XXX -> samsung_dma_XXX
Hmm, i was missing about the DMA on the prior mail. We should consider the DMA with this. The DMA chip(PL330) of s5p CPUs differs with s3c CPUs. We first should desided whether use the existing DMA interface of s3c. If we use it, this prefix is better samsung than s3c.
The other option is using the DMA subsystem about s5p DMA. This need also implementing ASoC platform driver of s5p for DMA, so it is better two each different prefix than samsung. I have posted the s5p DMA driver using the DMA subsystem. http://lists.infradead.org/pipermail/linux-arm-kernel/2009-September/000810....
