[PATCH 02/14] soc: renesas: Identify R-Car H3e-2G and M3e-2G

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add support for identifying the R-Car H3e-2G (R8A779M1) and R-Car M3e-2G
(R8A779M3) SoCs.

As these are different gradings of the already supported R-Car H3 ES3.0
(R8A77951) and M3-W+ (R8A77961) SoCs, support for them is enabled
through the existing ARCH_R8A77951 and ARCH_R8A77961 configuration
symbols.

Question: Should we drop fam_rcar_gen3e and soc_rcar_[hm]3e, and just
	  use the existing soc_rcar_h3 and soc_rcar_m3_w?
