From ed11f1ead54bf0398a4303b51125622113c9c9e1 Mon Sep 17 00:00:00 2001 From: Doug Anderson Date: Wed, 23 Apr 2014 08:56:05 -0700 Subject: [PATCH] regulator: tps65090: Make FETs more reliable by adding retries An issue was discovered with tps65090 where sometimes the FETs wouldn't actually turn on when requested (they would report overcurrent). The most problematic FET was the one used for the LCD backlight on the Samsung ARM Chromebook (FET1). Problems were especially prevalent when the device was plugged in to AC power (when the backlight voltage was higher). Mitigate the problem by adding retries on the enables of the FETs, which works around the problem fairly effectively.
