Subject: [PATCH v3 0/2] Delete MT8192 msdc gate (was "clk: mediatek: Delete MT8192 msdc gate")

From: Matthias Brugger <[email protected]>


The mt8192-msdc clock is only a single clock gate. This gate is accessed
from the mmc driver directly. With
4a1d1379ebf6 ("arm64: dts: mt8192: Add mmc device nodes")
the only consumer of this binding was deleted. Delete the binding
decription and the clock driver bound to it.

Changes in v3:
- Update commit message to explain better why we do ABI breakage here
- add Reviewed-by tag

Changes in v2:
- Delete compatible in binding descprition as well
- Add RvB tags
- add Reviewed-by tag

Subject: [PATCH v3 1/2] dt-bindings: ARM: Mediatek: Remove msdc binding of MT8192 clock

From: Matthias Brugger <[email protected]>

The code controlling msdc clock gate was moved inthe the consumer, the MMC
driver. This node did never represent a working implementation of any
peripheral. It was just a lonely clock gate that wasn't used. Delete the
binding description of this node.
