Hi All,
This patch series adds support to identify the Renesas RZ/Five SoC.
Below is the output tested on SMARC EVK based on RZ/Five SoC:
/ # dmesg | grep Detect
[ 0.065230] Detected Renesas RZ/Five r9a07g043 Rev 0
/ # cat /sys/devices/soc0/family

/ # cat /sys/devices/soc0/revision

/ # cat /sys/devices/soc0/soc_id

Document RZ/Five (R9A07G043) SYSC bindings. The SYSC block found on the
RZ/Five SoC is almost identical to one found on the RZ/G2UL (and alike)
SoC's. "renesas,r9a07g043-sysc" compatible string will be used on the
RZ/Five SoC so to make this clear, update the comment to include RZ/Five
SoC.
The SYSC block on RZ/Five has no interrupts to the core so to accommodate
this SoC make interrupts{,-names} properties optional.

i.e. will queue in renesas-devel for v6.1.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
