Subject: [PATCH v5 4/9] arm64: dts: realtek: rtd129x: Add irq muxes and UART interrupts
Date: Thu, 21 Nov 2019 06:02:03 +0100 [thread overview]
Message-ID: <20191121050208.11324-5-afaerber@suse.de> (raw)
In-Reply-To: <20191121050208.11324-1-afaerber@suse.de>
Add iso and misc IRQ mux DT nodes to RTD129x SoC family.
Update the UART DT nodes with interrupts from these muxes,
so that UART0 can be used without earlycon.
Signed-off-by: Andreas Färber <afaerber@suse.de>
---
v4 -> v5: Unchanged
v3 -> v4:
* Rebased onto chip-info and r-bus
* Dropped schema-violating second interrupts for UART1 and UART2
v2 -> v3:
* Added nodes to rtd129x.dtsi instead of rtd1295.dtsi
* Adopted misc compatible string
* Renamed node label from irq_mux to misc_irq_mux for clarity
v1 -> v2:
* Rebased
