Subject: arm64: dts: rockchip: Make Jaguar PCIe-refclk pin use pull-up config
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=f45d4356feeba1c8dac3414b688f59292ddfc9f9;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: rockchip: Make Jaguar PCIe-refclk pin use pull-up config

The hardware PU/PD config of the pin after reset is to pull-up and on
Jaguar this will also keep the device in reset until the driver actually
enables the pin. So restore this boot pull-up config of the pin on Jaguar
instead of setting it to pull-none.
