[U-Boot] [PATCH] arm: mvebu: switch clearfog to use device-tree i2c and gpio
From: Jon Nettleton jon@solid-run.com
This switches the clearfog boards to use DM based gpio and i2c drivers. The io expanders are configured via their device-tree entries.

The context lines in this patch depend on the patch adding SATA support.

Will this actually work? As far as I can see u-boot lacks a gpio-hog implementation so despite the fact that these are all enumerated in the dts they won't have the same effect.

I asked Jon (back on Cc) exactly that before submitting this patch. His response:
I think that is fine. They can still be toggled and controlled via the gpio interface within u-boot. I assume once a proper patch is mainline this will just start to work.
My testing showed now regression because of this patch.
Thanks for reviewing, baruch

OK. Did you test with a power cycle? I know some of the pca gpio chips don't have a reset line so the state may be different depending on if you power cycled or just used the reset/reboot command. It could also be that u-boot doesn't access these devices so there's no problem.
I kinda was hoping for "here's a gpio-hog implementation @ patchwork/1234" :) but I guess I'll have to look into making one myself.
Thanks for reviewing,
Assuming there's no problem with power-on behaviour

I would prefer to not drop these I2C accesses from the ClearFog board C code now, as we don't have a way to do this via the DT right now. Why are they dropped with this patch? Because of the I2C API changes? Please move to the DM I2C API then (dm_i2c_read/write).

Stefan,
These do not need to be setup independently any longer. Moving to DM_GPIO allows the PCI driver to handle the reset lines. The USB3 reset and current limiter should be handled in board_xhci_enable() which can be done, although I have never seen an issue using USB3 with this configuration since I have implemented it. Since u-boot doesn't understand the SFP setup at all I would prefer if it left SFP configuration up to Linux. Just enabling TX on an SFP module without understanding any of the specifics of the configuration is a bit dangerous when dealing with modules that aren't just SGMII 1000base-Tx.
I will follow up with a patch for board_xhci_enable().
Thanks, Jon

Thanks for the explanation. With this I'm okay with removing the I2C code from the board file:
