| Subject: arm64: tegra: Make BCM89610 PHY interrupt as active low |
| |
| From: Bhadram Varka <vbhadram@nvidia.com> |
| |
| [ Upstream commit 9df50ba76ac1485b844beffa1f3f5d9659d9cdaf ] |
| |
| 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. |
