Hi Simon, Magnus,
This patch series upgrades the version of the PSCI firmware, as
advertised in DT on Renesas R-Car Gen3 systems, from v0.2 to v1.0.
Note that this series does not have any runtime effects: as of PSCI
v0.2, PSCI provides a VERSION API. Hence Linux always detected the
actual version, regardless of what was stated in DT, and enabled v1.0
features like system suspend:
PSCIv1.0 detected in firmware.
However, it is better to have the real hardware^H^H^H^H^H^H^H^Hfirmware
description in DT.
Changes compared to v1:
- Keep "arm,psci-0.2".
Tested on Salvator-X (both H3 and M3-W) with firmware v2.16.0, but I do
have old boot logs showing that PSCIv1.0 has been detected for a long
time.
Thanks for applying!
