Subject: Re: [PATCH v6 06/14] irqchip: gicv3-its: platform-msi: refactor its_pmsi_init() to prepare for ACPI
Date: Tue, 3 Jan 2017 08:41:29 +0100 [thread overview]
Message-ID: <8cdc4bfa-18a3-b9f6-aaba-0efe1f75fb40@semihalf.com> (raw)
In-Reply-To: <1483363905-2806-7-git-send-email-hanjun.guo@linaro.org>
Hi,
Can we merge patch 4 & 6 into one patch so that we keep refactoring part
as one piece ? I do not see a reason to keep them separate or have patch
5 in between. You can refactor what needs to be refactored, add
necessary functions to iort.c and then support ACPI for
irq-gic-v3-its-platform-msi.c
Thanks,
Tomasz
