From 9905370560d9c29adc15f4937c5a0c0dac05f0b4 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 10 Oct 2022 07:44:13 -0400 Subject: [PATCH] arm64: dts: qcom: sdm845-db845c: correct SPI2 pins drive strength The pin configuration (done with generic pin controller helpers and as expressed by bindings) requires children nodes with either: 1. "pins" property and the actual configuration, 2. another set of nodes with above point. The qup_spi2_default pin configuration uses alreaady the second method with a "pinmux" child, so configure drive-strength similarly in "pinconf". Otherwise the PIN drive strength would not be applied.
