Subject: [PATCH v5 4/5] soc: renesas: rz-sysc: Move RZ/V2H SoC detection to the SYS driver
As per the other SoC variant of the same family, the system controller
provides SoC ID in its own registers.
Signed-off-by: John Madieu <john.madieu.xa@...renesas.com>
---
Changes:
v5: Do not use common included file with RZ/G3E and set proper hex values for
register offset and mask definition
v3 -> v4: No changes
v3: New patch
