Commit Message

Refactor renesas_sdhi_probe() to avoid increasing numbers of
sdhi_quirks_match[] entry when we add other stable SoCs like
r8a779m*.

Note that the sdhi_quirks_match[] is only needed on
renesas_sdhi_internal_dmac.c so that of_data of
renesas_sdhi_sys_dmac.c keeps as-is.

Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>
Reported-by: kernel test robot <lkp@intel.com> # build fix on RFC
---
 - I tested this patch on r8a77951 (ES3.0), r8a77960 (ES1.0) and r8a77965.
 - Also I tested this patch on r8a7791.

 Changes from RFC v2:
 - Remove "RFC" mark from the subject.
 - Add a comment to the Reported-by tag.
 - Move all quirks to internal_dmac.c so that expands the renesas_sdhi_probe()
   arguments. So, update the commit subject and description.
 - Don't modify the renesas_sdhi_sys_dmac.c's of_data.
 - Replace tabs with a space in of_data_with_quirks variables.
 https://lore.kernel.org/linux-renesas-soc/20210629102033.847369-1-yoshihiro.shimoda.uh@renesas.com/

 Changes from RFC v1:
 - Fix build error in sys_dmac.c, reported by kernel test robot, so that
   add Reported-by tag.
 - Always set quirks, not using else statement.
 - Fix a NULL dereference if of_device_get_match_data() returns NULL.

Hi Shimoda-san,

Thanks for your patch!

Cool, then we won't need "[PATCH 04/14] mmc: renesas_sdhi: Add support
for R-Car H3e-2G and M3e-2G"
(https://lore.kernel.org/r/22b4c393bf5074b53791d2797d8fe74deb8ea9a7.1623315732.git.geert+renesas@glider.be).

I would drop this tag, as it is basically a test/review comment for
an older version of a patch.

I think the code would be easier to read without the interleaving of
of_device_get_match_data() and soc_device_match() based matching, ...

... and without using the ternary operator, like:

    of_data_quirks = of_device_get_match_data(&pdev->dev);
    quirks = of_data_quirks->quirks;

    attr = soc_device_match(soc_dma_quirks);
    if (attr)
            global_flags |= (unsigned long)attr->data;

    attr = soc_device_match(sdhi_quirks_match);
    if (attr)
            quirks = attr->data;

    [...]

    return renesas_sdhi_probe(pdev, &renesas_sdhi_internal_dmac_dma_ops,
                              of_data_quirks->of_data, quirks);

Regardless, as this doesn't impact functionality:
