+From 3eeb897a627e26083472f14e7512f53276a5e7ce Mon Sep 17 00:00:00 2001
+From: Yingjoe Chen <yingjoe.chen@mediatek.com>

+Subject: [PATCH 50/76] pinctrl: mediatek: data struct optimize and remove
+ unused member
+
+struct mtk_desc_pin.chip, mtk_pinctrl_devdata.invser_offset
+and mtk_pinctrl_devdata.chip_type are never used in code.
+Remove them.
+
+Some per-pin data are using int for pin number and offsets.
+Change to short and rearrange to reduce const data size.
