Alex:

    you can superseded this serie. According to mirquel's suggestion,

I splitted into 4 parts:
	1. svc driver fix patches: https://lore.kernel.org/imx/ZvwpMBWzNjTXpPZF@lizhi-Precision-Tower-5810/T/#t
	2. i3c master fix patches with miquel's ack
	   a: https://lore.kernel.org/imx/20241001162608.224039-1-Frank.Li@nxp.com/T/#u
	   b: https://lore.kernel.org/imx/20241001162232.223724-1-Frank.Li@nxp.com/T/#u
	3. ongoing discussion on about dt assigne address:
	   https://lore.kernel.org/imx/20241001-i3c_dts_assign-v1-0-6ba83dc15eb8@nxp.com/T/#t

    I hope above help you manage these patches.
