Ok, I made a mistake in the interrupt configuration, I'm using P5_8 which is IRQ0, here are the lines I modified:void __iomem *irc1 = IOMEM(0xfcfef802);__raw_writew((__raw_readw(irc1) & ~(0x3)),...

Hi,You should read the "RZ/A1H Group, RZ/A1M Group User’s Manual: Hardware" Rev.2.0, Feb 2015.I thinkrza1_pfc_pin_assign(P5_8, ALT8, DIR_OUT);should be:rza1_pfc_pin_assign(P5_8, ALT2,...

I've been setting IRQ pins to DIIO_PBDC_DIS which also seems to work finer7s72100_pfc_pin_assign(P5_8, ALT2, DIIO_PBDC_DIS); /* IRQ0 */

I tried both solutions, but if I try cat /proc/interrupts I see nothing.Also I'm still missing /dev/input/event0.Thank you again for your help!

Honestly, I would say at first, just comment out ret = wlcore_probe_of(&func->dev, &irq, &pdev_data);and just hard code the values to get the driver up and running.Yes, the correct...

I need to use the latest backported drivers from TI to support a radio with the RZA1. Previous versions of these drivers supported platform data set from a board file, or device tree data. Now, the...

Thanks Chris - it turns out I needed to some code in the TI kernel driver to clear the interrupt for the Renesas in the TI wl18xx.ko interrupt handler code... This at least allows the WiFi module to...

Thanks Chris - that is what I did. I removed the code that parsed the device tree and coded my IRQ to 38 and RISING edge. The driver now works.

Yes, writing a 0 to the IRQF bit in the IRQRR register is the correct way to cancel an interrupt.Like you are doing above, the chip wants to first see the cpu READ that bit as a '1' before you can...

Cool.If you get all this working, maybe you can post a list of what you did so I (or someone else) could try it themselves if they want.This chip seems to be getting popular for WiFi and BLE applications.
