Hi Mark,
I'm looking at the omap-serial driver and saw that you added rts-gpio
binding in commit 4a0ac0f55b18dc297a87a85417fcf068658bf103 (OMAP: add
RS485 support) but, as it turns out, gpio0_13 and gpio2_15 are both
actual RTS signals.
Instead of
We have a custom AM335x board where the USB0_ID pin has been left floating.
By default, this puts the USB controller into peripheral mode, but we need
to force it into host mode.
This can be achieved in s/w by setting some bits in the relevant USB mode
register (see TRM 16.5.2.35).
This mode
The IDDIG input pin is normally used to determine the USB mode
(i.e. HOST or DEVICE).
On some systems (e.g. AM335x) leaving this pin floating allows
the USB mode to be set via software.
This patch adds support for this via the device tree.

Before I dig any deeper, can anyone tell me if the bootarg mpurate is meant to
be supported for AM335x SoCs ?
I've tried it on our custom board using 3v8, but no joy.
The boot log shows:-

I'm hitting an issue where I want to register my GPMC connected NAND on CS0 at
address 0x0.
Here's the relevant error from the boot messages:-

Just found the existing thread that already covers this.
Sorry for the noise.

Okay ... I have made some progress, but it's not ideal.
Currently I've hacked the GPMC DT driver (gpmc_probe_dt(), etc) so it now
handles setting up the
chip selects and timings for NOR devices, e.g.
gpmc: gpmc@5000 {

But the physmap driver (of_flash_probe()) is unable to use this information.
It seems that although
I can call of_flash_probe() from my NOR setup code, the platform_device being

There's plenty of DT support going in for NAND flash, but is there any work

flash ?
And how about SRAM chips or other memory mapped devices ?
