[Patch v2 2/3] arm64: dtsi: ls1028a: Update flexcan properties

[Kuldeep Singh <kuldeep.singh@nxp.com>]

LS1028A supports two flexcan controllers similar to LX2160A.

There's already a compatible entry defined i.e "fsl,lx2160ar1-flexcan"
which can be further reused for LS1028A.
Please note, "fsl,ls1028ar1-flexcan" compatible entry doesn't exists and
can be safely removed.

LS1028A has a single peripheral clock (i.e platform clock) source
connected to both "ipg" and "per" and therefore, remove "sysclk" as
clock source from device-tree.

Hi Shawn,
I would like to mention the motivation behind compatible string change.
There's no ls1028a compatible entry i.e " fsl,ls1028ar1-flexcan" in flexcan
driver. See below.
https://elixir.bootlin.com/linux/latest/source/drivers/net/can/flexcan.c#L1913

And the documentation says that ls1028a entry should be followed by lx2160a.
https://elixir.bootlin.com/linux/latest/source/Documentation/devicetree/bindings/net/can/fsl,flexcan.yaml#L42

Since ls1028a entry is not present, anyway lx2160a entry will be eventually used.
Please let me know your views.
