Subject: i2c-xiic driver changes from Cisco
Date: Tue, 2 Dec 2025 17:04:28 +0000 [thread overview]
Message-ID: <aS8cG4Otywg1kIcr@goliath> (raw)
Hi,
We have a slightly modified version of the Xilinx IP which the i2c-xiic.c
sources seem to support.
We made one (or at least one) change to the IP were we don't supply it with an
interrupt line. It doesn't appear the driver supports this configuration.
Is that accurate to your knowledge ?
If the drivers doesn't support some type of polling mode, is Xilinx willing to accept
changes which would make the driver compatible with a polling mode if an
interrupt is not supplied thru the device tree ?
It seems like it makes sense the driver should support a polling mode because
Xilinx customers may make a product where the interrupt line doesn't function
properly. In that case the customer would need a contingency which could be
polling for interrupts.
Daniel
