Subject: [PATCH v2 04/65] PCI: designware: Fix PORT_LOGIC_LINK_WIDTH_MASK
Date: Sun, 16 Dec 2018 21:18:24 -0800 [thread overview]
Message-ID: <20181217051925.17582-5-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20181217051925.17582-1-andrew.smirnov@gmail.com>
Port of a Linux commit ed8b472df44af6dc4cb18e828dc9bb2d57f14b9e
The value under PORT_LOGIC_LINK_WIDTH_MASK is 0x1, 0x2, 0x4, 0x8. In IP
v4.2, bits [16:8] are defined for NUM_OF_LANES. But in IP v4.4, bits[12:8]
are defined for NUM_OF_LANES, bits [16:13] are for other usages (bit 16 is
AUTO_LANE_FLIP_CTRL_EN, bits [15:13] are PRE_DET_LANE).
As there is no conflict about NUM_OF_LANES between v4.2 and v4.4, change
the mask value to avoid future problems.
