| Subject: ARM: dts: exynos: Disable pull control for PMIC IRQ line on Artik5 |
| board |
| |
| From: Marek Szyprowski <m.szyprowski@samsung.com> |
| |
| [ Upstream commit 62623718fd31d08b26ebea6c8b40f24924153ab7 ] |
| |
| S2MPS14 PMIC interrupt line on Exynos3250-based Artik5 evaluation board |
| has external pull-up resistors, so disable any pull control for it in |
| controller node. This fixes support for S2MPS14 PMIC interrupts and |
| enables operation of wakeup from S2MPS14 RTC alarm. |
