Plus this breaks compatibility. Actually, it has glue layer, such as wakeup controller. Remote wakeup have not implement at layerscape platform yet. But this register distribute to difference place with other module misc controller registers. It is difference for difference chips. I can think deep how to handle this. but anyways, it will break compatibility. I have not find good way to keep compatibility and add glue layer, such as wakeup support.

If so, I'll wait until > you resolve this issue and review the rest. Rob: I checked many dwc3-of-simple.c compatible string, which have not 'reg' and just have some clocks and reset. Is it okay to add missed clock and fsl,rcpm for usb wakeup support in gluelayer node? Frank > > BR, > Thinh

New usb glue layer driver support enable dma-coherent. So put dwc3 usb node under glue layer node and enable dma-coherent. Signed-off-by: Frank Li <Frank.Li@nxp.com> --- arch/arm64/boot/dts/freescale/fsl-ls1028a.dtsi | 43 ++++++++++++++++---------- 1 file changed, 26 insertions(+), 17 deletions(-)
