From 0fe52ae0b5e2e2625119ab5f6791c396380d5e86 Mon Sep 17 00:00:00 2001 From: Priit Laes Date: Wed, 21 Nov 2018 20:05:33 +0200 Subject: [PATCH] arm: sunxi: Reduce inrush current on Olimex OLinuXino-A20-Lime2-eMMC The lime2 features a too large capacitor on the LDO3 output, which causes the PMIC to shutdown when enabling power. To be able to still boot up however, we must gradually enable power on LDO3 for this board. We do this by enabling both the inrush quirk and the maximum slope the AXP209 supports.
