From e023cc4abde3c01b895660b0e5a8488deb36b8c1 Mon Sep 17 00:00:00 2001 From: Jeff LaBundy Date: Tue, 3 Jan 2023 11:58:59 -0600 Subject: Input: iqs269a - increase interrupt handler return delay The time the device takes to deassert its RDY output following an I2C stop condition scales with the core clock frequency. To prevent level-triggered interrupts from being reasserted after the interrupt handler returns, increase the time before returning to account for the worst-case delay (~140 us) plus margin.
