Subject: [PATCH v2 01/10] dt-bindings: soc: mobileye: set `#clock-cells = <1>` for all compatibles
Date: Wed, 06 Nov 2024 17:03:52 +0100	[thread overview]
Message-ID: <20241106-mbly-clk-v2-1-84cfefb3f485@bootlin.com> (raw)
In-Reply-To: <20241106-mbly-clk-v2-0-84cfefb3f485@bootlin.com>

Some compatibles expose a single clock. For those, we used to let them
using `#clock-cells = <0>` (ie <&olb> reference rather than <&olb 0>).

Switch away from that: enforce a cell for all compatibles. This is more
straight forward, and avoids devicetree changes whenever a compatible
goes from exposing a single clock to multiple ones. Also, dt-bindings
get simpler.

*This is an ABI break*. Change it while EyeQ5 platform support is at its
infancy, without any user. More clocks might hide in each OLB as some
registers are still unknown.
