Subject: [PATCH v3 2/2] dt-bindings: gpio: add loongson series gpio
Date: Wed, 16 Nov 2022 14:53:35 +0800 [thread overview]
Message-ID: <20221116065335.8823-2-zhuyinbo@loongson.cn> (raw)
In-Reply-To: <20221116065335.8823-1-zhuyinbo@loongson.cn>
Add the Loongson series gpio binding with DT schema format using
json-schema.
Signed-off-by: Yinbo Zhu <zhuyinbo@loongson.cn>
---
Change in v3:
1. Separate some changes of MAINTAINERS file and enter the first patch.
Change in v2:
1. Drop "loongson,gpio_base" and "gpio-ranges" will cover it.
1. Drop "loongson,conf_offset", "loongson,out_offset", "loongson,in_offset",
"loongson,support_irq" and kernel driver will initial them that depend
compatible in kernel.
3. Fixup maintainer for this driver.
