| * soc: renesas: Register SoC device earlyGeert Uytterhoeven2017-04-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The r8a7795 SYSC driver manages PM Domains, and thus is initialized from an early_initcall(). However, this means the driver cannot check the SoC revision, as the SoC device hasn't been registered yet. Change renesas_soc_init() from a core_initcall() to an early_initcall() to fix this (renesas-soc.o is listed before rcar-sysc.o in the Makefile).

* soc: renesas: Identify SoC and register with the SoC busGeert Uytterhoeven2016-11-231-0/+257
Identify the SoC type and revision, and register this information with the SoC bus, so it is available under /sys/devices/soc0/, and can be checked where needed using soc_device_match(). Identification is done using the Product Register or Common Chip Code Register, as declared in DT (PRR only for now), or using a hardcoded fallback if missing. Example: Detected Renesas R-Car Gen2 r8a7791 ES1.0 ... # cat /sys/devices/soc0/{machine,family,soc_id,revision} Koelsch R-Car Gen2 r8a7791 ES1.0 Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
