Subject: [PATCH v2 16/22] pinctrl: mediatek: extend struct mtk_pin_desc which per-pin driver depends on
Date: Sat, 8 Sep 2018 19:07:32 +0800 [thread overview]
Message-ID: <8706de60fe75838b595d3be73681bbca344734a8.1536404280.git.sean.wang@mediatek.com> (raw)
In-Reply-To: <cover.1536404280.git.sean.wang@mediatek.com>
From: Sean Wang <sean.wang@mediatek.com>
Because the pincrl-mtk-common.c is an implementation for per-pin binding,
its pin descriptor includes more information than pinctrl-mtk-common-v2
so far can support. So, we complement these data before writing a driver
using pincrl-mtk-common-v2.c for per-pin binding. By the way, the size of
struct mtk_pin_desc would be larger than struct pinctrl_pin_desc can hold,
so it's necessary to have a copy before the pins information is being
registered into the core.

Subject: [PATCH v2 16/22] pinctrl: mediatek: extend struct mtk_pin_desc which per-pin driver depends on
Date: Sat, 8 Sep 2018 19:07:32 +0800 [thread overview]
Message-ID: <8706de60fe75838b595d3be73681bbca344734a8.1536404280.git.sean.wang@mediatek.com> (raw)
In-Reply-To: <cover.1536404280.git.sean.wang@mediatek.com>
From: Sean Wang <sean.wang@mediatek.com>
Because the pincrl-mtk-common.c is an implementation for per-pin binding,
its pin descriptor includes more information than pinctrl-mtk-common-v2
so far can support. So, we complement these data before writing a driver
using pincrl-mtk-common-v2.c for per-pin binding. By the way, the size of
struct mtk_pin_desc would be larger than struct pinctrl_pin_desc can hold,
so it's necessary to have a copy before the pins information is being
registered into the core.
