From 156f721704b5c9e8fae02270f606f09d710ff27e Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Tue, 22 Feb 2022 12:11:44 +0100 Subject: [PATCH] pinctrl: mediatek: common-v1: Commonize spec_ies_smt_set callback All of the MediaTek pinctrl drivers registering with pinctrl-mtk-common that are offering a .spec_ies_smt_set() callback are declaring their own function which is doing exactly the same on all drivers: calling mtk_pconf_spec_set_ies_smt_range() with their struct and a simple check. Commonize this callback by adding the ies and smt structure pointers to struct mtk_pinctrl_devdata and changing the callback signature to take it. Removing the callback and checking for the existance of the spec_smt and/or spec_ies data would allow us to staticize the function mtk_pconf_spec_set_ies_smt_range(), but this solution was avoided as to keep flexibility, as some SoCs may need to perform a very different operation compared to what this commonized function is doing.
