| | * | | soc: renesas: rcar-sysc: Fix power domain control after system resumeGeert Uytterhoeven2018-12-061-19/+9

Currently this is handled in the driver's probe() routine, and set up for every domain present, even if it will not be controlled directly by SYSC (CPU domains are powered through the APMU on R-Car Gen2 and later). On R-Car Gen3, PSCI powers down the SoC during system suspend, thus losing any configured interrupt state. Hence after system resume, power domains not controlled through the APMU (e.g. A3IR, A3VC, A3VP) fail to power up. Fix this by replacing the global interrupt setup in the probe() routine by a domain-specific interrupt setup in rcar_sysc_power(), where the domain's power is actually controlled. This brings the code more in line with the flowchart in the Hardware User's Manual.

However, this failed to realize that parent power domains must be powered up before their children anyway, and that this thus must be reflected by the order in the PM Domain tables.

As they are just one-line wrappers around rcar_sysc_power(), it makes sense to just remove them. This also avoids a bool/helper/bool conversion in rcar_sysc_power_cpu(), where a bool is checked to call one of two helper functions, which just call rcar_sysc_power() with hardcoded boolean values again.

As we leave the function, this will point to nowhere-land, and things will end-up badly.

This contains a firmware "ioctl" interface that was a little controversial at first, but the version we merged solved that by not exposing arbitrary firmware calls to user space. - The Amlogic Meson platform gains a "canvas" driver that is used for video processing and shared between different high-level drivers. The rest is more of the usual, mostly related to SoC specific power management support and core drivers in drivers/soc: - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new features related to power and reset control. - The Mediatek mt8183 and mt6765 SoC platforms gain support for their respective power management chips. - A new driver for NXP i.MX8, which need a firmware interface for power management. - The SCPI firmware interface now contains support estimating power usage of performance states - The NVIDIA Tegra "pmc" driver gains a few new features, in particular a pinctrl interface for configuring the pads. - Lots of small changes for Qualcomm, in particular the "smem" device driver. - Some cleanups for the TI OMAP series related to their sysc controller.
