Subject: [PATCH] sh: sh7757: switch RSPI clock to dev ID match

From: Geert Uytterhoeven <[email protected]>

Switch the RSPI MSTP clock on SH7757 from a con ID match to a dev ID
match, so we can start looking it up using clk_get() with a NULL ID.

Signed-off-by: Geert Uytterhoeven <[email protected]>

Untested, as I don't have the hardware, but this is a prerequisite for
"spi: rspi: Use NULL as the clock ID".

Is there anyone who can test this?

"spi: rspi: Use NULL as the clock ID" is queued for v3.15:
https://git.kernel.org/cgit/linux/kernel/git/broonie/spi.git/commit/drivers/spi/spi-rspi.c?h=for-next&id=29f397b739ceef90c8b848f6579cbacd088e896e
and this patch should go in first.

Thanks!

I could test this patch. And then, the patch worked correctly.

Thanks, I will add your Tested-by and send it to Andrew Morton.
