+Subject: [PATCH] pinctrl: rockchip: correct RK3328 iomux width flag for
+ GPIO2-B pins
+
+The base iomux offsets for each GPIO pin line are accumulatively
+calculated based off iomux width flag in rockchip_pinctrl_get_soc_data.
+If the iomux width flag is one of IOMUX_WIDTH_4BIT, IOMUX_WIDTH_3BIT or
+IOMUX_WIDTH_2BIT, the base offset for next pin line would increase by 8
+bytes, otherwise it would increase by 4 bytes.
+
+Despite most of GPIO2-B iomux have 2-bit data width, which can be fit
+into 4 bytes space with write mask, it actually take 8 bytes width for
+whole GPIO2-B line.
+
+Commit e8448a6c817c ("pinctrl: rockchip: fix pinmux bits for RK3328
+GPIO2-B pins") wrongly set iomux width flag to 0, causing all base
+iomux offset for line after GPIO2-B to be calculated wrong. Fix the
+iomux width flag to IOMUX_WIDTH_2BIT so the offset after GPIO2-B is
+correctly increased by 8, matching the actual width of GPIO2-B iomux.
+
