This is a note to let you know that I've just added the patch titled mfd: cpcap: Fix interrupt to use level interrupt to the 4.11-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: mfd-cpcap-fix-interrupt-to-use-level-interrupt.patch and it can be found in the queue-4.11 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From ac89473213c602b98172d92e40f5e78032b1aba0 Mon Sep 17 00:00:00 2001 From: Tony Lindgren <tony@xxxxxxxxxxx> Date: Mon, 3 Apr 2017 20:15:54 -0700 Subject: mfd: cpcap: Fix interrupt to use level interrupt From: Tony Lindgren <tony@xxxxxxxxxxx> commit ac89473213c602b98172d92e40f5e78032b1aba0 upstream. I made a mistake assuming the device tree configuration for interrupt triggering was somehow passed to the SPI device but it's not. In the Motorola Linux kernel tree CPCAP PMIC is configured as a rising edge triggered interrupt, but then then it's interrupt handler keeps looping until the GPIO line goes down. So the CPCAP interrupt is clearly a level interrupt and not an edge interrupt. Earlier when I tried to configure it as level interrupt using the device tree, I did not account that the triggering only gets passed to the SPI core and it also needs to be specified in the CPCAP driver when we do devm_regmap_add_irq_chip().
