Subject: [PATCH v2 01/21] PCI: keystone: Use quirk to limit MRRS for K2G
Date: Wed, 17 Oct 2018 13:10:54 +0530	[thread overview]
Message-ID: <20181017074114.28239-2-kishon@ti.com> (raw)
In-Reply-To: <20181017074114.28239-1-kishon@ti.com>

PCI controller in K2G also has a limitation that memory read request
size (MRRS) must not exceed 256 bytes. Use the quirk to limit MRRS
(added for K2HK, K2L and K2E) for K2G as well.
