Subject: arm64: dts: qcom: sdm845-db845c: correct SPI2 pins drive strength
From: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>
commit 9905370560d9c29adc15f4937c5a0c0dac05f0b4 upstream.
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.
