Subject: [PATCH v10 12/12] ARM: dts: zte: Declare zx297520v3 CRM device nodes
Date: Mon, 10 Aug 2026 10:03:10 +0300 [thread overview]
Message-ID: <20260810070311.1110849-1-stefandoesinger@gmail.com> (raw)
In-Reply-To: <20260810-zx29clk-v10-0-63846490712c@gmail.com>
This makes use of the driver added in the previous patches. It wires up
the uart clocks and resets and allows getting rid of the placeholder
uartclk node.
Signed-off-by: Stefan Dösinger <stefandoesinger@gmail.com>
---
Version 10: Fix issues with dt-check-style --mode=strict in newly added
code, but left issues in existing nodes alone.
Version 9:
Sort new nodes by mmio address
rename syscon-reboot to "reboot"
adjust to changes in bindings
Version 7:
Add phy nodes to topcrm
Remove syscon from matrixclk again
Adapt remove now-removed extra clk inputs from matrix
Add reset to LSP
osc26m -> clock-26m for the fixed rate clocks, likewise for 32k
Version 6:
Add syscon to matrixclk
Version 5:
Re-name from *clk to *crm
Add the syscon-reboot node here because the binding requires it
Re-add accidentally dropped uart2 IRQ
