Subject: [PATCH 7/9] dt-bindings: i2c: i2c-rk3x: Allow use of a power-domain
Date: Sun, 18 May 2025 22:06:54 +0000 [thread overview]
Message-ID: <20250518220707.669515-8-jonas@kwiboo.se> (raw)
In-Reply-To: <20250518220707.669515-1-jonas@kwiboo.se>
The I2C controllers in most Rockchip SoCs are part or power domains that
are always powered on, i.e. PD_BUS or PD_PMU.
On RK3528 the I2C controllers are spread out among the PD_RKVENC, PD_VO
and PD_VPU power domains.
Add support to describe power-domains for the I2C controllers.
