Subject: arm64: tegra: Make BCM89610 PHY interrupt as active low
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9df50ba76ac1485b844beffa1f3f5d9659d9cdaf;p=openwrt%2Fstaging%2Fblogic.git

arm64: tegra: Make BCM89610 PHY interrupt as active low

Need to configure PHY interrupt as active low for P3310 Tegra186
platform otherwise it results in spurious interrupts.

This issue wasn't seen before because the generic PHY driver without
interrupt support was used.
