Subject: [PATCH v6 06/14] irqchip: gicv3-its: platform-msi: refactor its_pmsi_init() to prepare for ACPI
Date: Mon, 2 Jan 2017 21:31:37 +0800 [thread overview]
Message-ID: <1483363905-2806-7-git-send-email-hanjun.guo@linaro.org> (raw)
In-Reply-To: <1483363905-2806-1-git-send-email-hanjun.guo@linaro.org>
Introduce its_pmsi_init_one() to refactor the code to isolate
ACPI&DT common code to prepare for ACPI later.
