From 26a0ba5d1654f11d1c786eb54f60a916b070ea6b Mon Sep 17 00:00:00 2001 From: Luca Weiss Date: Mon, 1 May 2023 17:01:45 -0700 Subject: [PATCH] Input: drv260x - sleep between polling GO bit [ Upstream commit efef661dfa6bf8cbafe4cd6a97433fcef0118967 ] When doing the initial startup there's no need to poll without any delay and spam the I2C bus. Let's sleep 15ms between each attempt, which is the same time as used in the vendor driver.
