From mboxrd@z Thu Jan 1 00:00:00 1970 From: k.kozlowski@samsung.com (Krzysztof Kozlowski) Date: Thu, 02 Apr 2015 16:36:16 +0200 Subject: [PATCH 2/2] ARM: dts: Fix pinctrl settings for S2MPS11 RTC alarm IRQ on Arndale Octa In-Reply-To: <1427985376-20420-1-git-send-email-k.kozlowski@samsung.com> References: <1427985376-20420-1-git-send-email-k.kozlowski@samsung.com> Message-ID: <1427985376-20420-3-git-send-email-k.kozlowski@samsung.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org On Arndale Octa the S2MPS11 RTC alarm interrupt was not handled at all because of wrong configuration of interrupt and gpx3-2. 1. Interrupt is signaled by falling edge. 2. This GPIO line is hard-wired on the board to PVDD_APIO_1V8 through a resistor so pull-up/down must be disabled.
