This patch is unreadable and needs to be split.
Also, why are you making duplicate copies of the same generic
functions?
Now you've copied these into mach-omap1/dma.c:
> +set_src_params(int lch, unsigned long src_start, int src_ei, int src_fi)
> +{
> + dma_write(src_start, CSSA, lch);
> +
> + dma_write(src_ei, CSEI, lch);
> + dma_write(src_fi, CSFI, lch);
> +}
> +
> +static void set_dest_params(int lch, unsigned long dest_start, int dst_ei,
> + int dst_fi)
> +{
> + dma_write(dest_start, CDSA, lch);
> +
> + dma_write(dst_ei, CDEI, lch);
> + dma_write(dst_fi, CDFI, lch);
> +}
...
And then again the same functions in mach-omap2/dma.c:
> +static void omap2_set_src_params(int lch, unsigned long src_start, int
> src_ei,
> + int src_fi)
> +{
> + dma_write(src_start, CSSA, lch);
> +
> + dma_write(src_ei, CSEI, lch);
> + dma_write(src_fi, CSFI, lch);
> +}
> +
> +static void omap2_set_dest_params(int lch, unsigned long dest_start, int
> dst_ei,
> + int dst_fi)
> +{
> + dma_write(dest_start, CDSA, lch);
> +
> + dma_write(dst_ei, CDEI, lch);
> + dma_write(dst_fi, CDFI, lch);
> +}
...
All the common functions should stay in plat-omap/dma.c.
