Hi Geert and Laurent,
This series adds support to control the drive strength for none GPIO
pins. All pins which can have its drive strength controlled is now supported. I
have also added the new pins to the correct groups, or added groups to mimic
other sh-pfc drivers. One notable exception is the group avb_mdc which on other
SoC are called avb_mdio, see commit 3/4 for explanation.
The series is based on top of v4.9-rc3 and tested on Salvator-X. My test
is a bit crude and is setting a few of the AVB pins to a higher
drive-strength value then the others and observing that the AVB fails to
work after the pfc settings are applied (NFS root failing to mount after
kernel is fetched over TFTP). I also tested setting the drive strength for
individual pins and for whole groups.
Changes since v1
- Add comment about that it's the R-Car H3SiP pin matrix which is used to
generate a unique id number for each pin. Even if the pin matrix are
different on other packages all the driver care about is that it's a unique
number.
- Add FSCLKST pin after discussion with Geert
- Moved avb_mii group relative to other avb pin groups for a more logical
order, thanks Sergei for pointing this out
- Add Acked-by and Reviewed-by tags
- Fixed spelling error
