From mboxrd@z Thu Jan 1 00:00:00 1970 From: andreas.herrmann@calxeda.com (Andreas Herrmann) Date: Fri, 17 Jan 2014 12:08:30 +0100 Subject: [PATCH v2 08/11] of: Increase MAX_PHANDLE_ARGS In-Reply-To: <1389876263-25759-9-git-send-email-andreas.herrmann@calxeda.com> References: <1389876263-25759-1-git-send-email-andreas.herrmann@calxeda.com> <1389876263-25759-9-git-send-email-andreas.herrmann@calxeda.com> Message-ID: <20140117110830.GW3471@alberich> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org arm-smmu driver uses of_parse_phandle_with_args when parsing DT information to determine stream IDs for a master device. Thus the number of stream IDs per master device is bound by MAX_PHANDLE_ARGS. To support Calxeda ECX-2000 hardware arm-smmu driver requires a slightly higher value for MAX_PHANDLE_ARGS as this hardware has 10 stream IDs for one master device. Increasing it to 16 seems a reasonable choice.
