Hello,
I've written a driver for snps,dw-mshc, which is compatible with SDHC spec.
Basically I've just copy pasted the dove-sdhci.c one and modified a few
lines to add:
* support for host_v4 mode
* 64 bit addressing
* 64-bit SDMA
* PIO mode
* Support for 10-bit clock divider (max divider of 2046 instead of 256)
Chosing between SDMA and PIO is done with Kconfig defines at compile
time. It's either one or the other.
Since snps,dw-mshc and dove-sdhci share the same code, because both
respect SDHC spec I would propose to rename dove-sdhci.c into sdhci.c
and remove all dove mentions inside.
Then write a dove-sdhci.c which registers via the sdhci generic layer
and same thing for dw-mshc.
This allows lot of code sharing between SDHC compatible devices and also
eases a lot the writing of new drivers.
Would that be OK?
Thanks!
Best regards,
