| Subject: [PATCH] arm64: tegra: Fix 'active-low' warning for Jetson TX1 |
| regulator |
| |
| commit 1e5e929c009559bd7e898ac8e17a5d01037cb057 upstream. |
| |
| Commit 34993594181d ("arm64: tegra: Enable HDMI on Jetson TX1") |
| added a regulator for HDMI on the Jetson TX1 platform. This regulator |
| has an active high enable, but the GPIO specifier for enabling the |
| regulator incorrectly defines it as active-low. This causes the |
| following warning to occur on boot ... |
| |
| WARNING KERN regulator@10 GPIO handle specifies active low - ignored |
| |
| The fixed-regulator binding does not use the active-low flag from the |
| gpio specifier and purely relies of the presence of the |
| 'enable-active-high' property to determine if it is active high or low |
| (if this property is omitted). Fix this warning by setting the GPIO |
| to active-high in the GPIO specifier which aligns with the presense of |
| the 'enable-active-high' property. |
