| Subject: [PATCH] arm64: dts: rockchip: fix Rockpro64 RK808 interrupt line |
| |
| commit deea9f5fc32040fd6f6132f2260ba410fb5cf98c upstream. |
| |
| Fix the pinctrl and interrupt specifier for RK808 to use GPIO3_B2. On the |
| Rockpro64 schematic [1] page 16, it shows GPIO3_B2 used for the interrupt |
| line PMIC_INT_L from the RK808, and there's a note which translates as: |
| "PMU termination GPIO1_C5 changed to this". |
| |
| Tested by setting an RTC wakealarm and checking /proc/interrupts counters. |
| Without this patch, neither the rockchip_gpio_irq counter for the RK808, |
| nor the RTC alarm counter increment when the alarm time is reached. |
| With this patch, both interrupt counters increment by 1 as expected. |
