Subject: [PATCH 0/2] arm64: dts: renesas: Upgrade to PSCI v1.0 to support Suspend-to-RAM
Date: Fri, 17 Feb 2017 18:00:30 +0100	[thread overview]
Message-ID: <1487350832-29820-1-git-send-email-geert+renesas@glider.be> (raw)

	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.

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!
