From a8dad3e1e333051ecc24d2349cfcd9b95225af87 Mon Sep 17 00:00:00 2001 From: Loic Poulain Date: Tue, 24 Mar 2020 11:07:52 +0100 Subject: [PATCH] arm64: dts: hikey960: pinctrl: Fix spi2/spi3 pinconf Only the pinmux was selected, not the pinconf, leading to spi issues. Increase drive strength so that max speed (25Mhz) can be achieved.
