Subject: [PATCH v4 2/4] arm64: dts: rockchip: add GRF GPIO controller to rk3328
Date: Tue, 31 Jul 2018 13:59:20 +0800 [thread overview]
Message-ID: <1533016762-5268-3-git-send-email-djw@t-chip.com.cn> (raw)
In-Reply-To: <1533016762-5268-1-git-send-email-djw@t-chip.com.cn>
From: Levin Du <djw@t-chip.com.cn>
Adding a GRF GPIO controller labled "grf_gpio" to rk3328, currently
providing access to the GPIO_MUTE pin, which is manupulated by the
GRF_SOC_CON10 register.
The GPIO_MUTE pin is referred to as <&grf_gpio 0>.
Signed-off-by: Levin Du <djw@t-chip.com.cn>
---
Changes in v4:
- Use binding of "rockchip,rk3328-grf-gpio"
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.
