Subject: [PATCH v3 3/5] arm64: dts: rockchip: Add GPIO_MUTE pin support to rk3328
Date: Thu, 31 May 2018 11:27:51 +0800	[thread overview]
Message-ID: <1527737273-8387-4-git-send-email-djw@t-chip.com.cn> (raw)
In-Reply-To: <1527737273-8387-1-git-send-email-djw@t-chip.com.cn>

From: Levin Du <djw@t-chip.com.cn>

Adding a new gpio controller named "gpio_mute" to rk3328, providing
access to the GPIO_MUTE pin, which is manupulated by the GRF_SOC_CON10
register.

The GPIO_MUTE pin is referred to as <&gpio_mute 0>.

Signed-off-by: Levin Du <djw@t-chip.com.cn>

---

Changes in v3:
- Use dedicated "rockchip,rk3328-gpio-mute" driver

Changes in v2:
- Rename gpio_syscon10 to gpio_mute in rk3328.dtsi

Changes in v1:
- Split from V0 and add to rk3328.dtsi for general use.
