[PATCH 11/16] soc: renesas: rcar-rst: Add support for R-Car S4-8

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

 



Add support for R-Car S4-8 (R8A779F0) to the R-Car RST driver.
The register map of R-Car S4-8 is the same as R-Car V3U so that
renames "V3U" and "r8a779a0" with "Gen4".
