2018-01-15soc: bcm: brcmstb: Be multi-platform compatibleThierry Reding1-9/+29
We were making a bunch of wrong assumptions that turned out to blow out on non-Broadcom STB platforms: - we would return -ENODEV from brcmstb_soc_device_early_init() if we could not find the sun_top_ctrl device node, this is not an error in the context of a multi-platform kernel - we would still try to register the Broadcom STB SoC device, even if we are not running on such a platform While at it, also fix the sun_top_ctrl device_node leaks while we change the flow of brcmstb_soc_device_init() and brcmstb_soc_device_early_init().

2018-01-11soc: brcmstb: Only register SoC device on STB platformsThierry Reding1-0/+5
After moving the SoC device initialization to an early initcall in commit f780429adfbc ("soc: brcmstb: biuctrl: Move to early_initcall"), the Broadcom STB SoC device is registered on all platforms if support for the device is enabled in the kernel configuration. This causes an additional SoC device to appear on platforms that already register a native one. In case of Tegra the STB SoC device is registered as soc0 (with totally meaningless content in the sysfs attributes) and causes various scripts and programs to fail because they don't know how to parse that data. To fix this, duplicate the check from brcmstb_soc_device_early_init() that already prevents the code from doing anything nonsensical on non- STB platforms.

Currently this is handled in device-specific drivers by explicitly increasing the use count of the module clock when the device is configured as a wakeup source. However, the proper way to prevent the device from being stopped is to inform this requirement to the genpd core, by setting the GENPD_FLAG_ACTIVE_WAKEUP flag. Note that this will only affect devices configured as wakeup sources." * tag 'renesas-soc2-for-v4.16' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: soc: renesas: rcar-sysc: Keep wakeup sources active during system suspend Signed-off-by: Olof Johansson <olof@lixom.net>

2017-12-20soc: qcom: smsm: fix child-node lookupJohan Hovold1-2/+4
Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children. Note that the original premature free of the parent node has already been fixed separately. Also note that this pattern of looking up the first child node with a given property is rare enough that a generic helper is probably not warranted.

2017-12-20soc: renesas: rcar-sysc: Keep wakeup sources active during system suspendGeert Uytterhoeven1-1/+1
If an R-Car SYSC slave device is part of the CPG/MSTP or CPG/MSSR Clock Domain and to be used as a wakeup source, it must be kept active during system suspend. Currently this is handled in device-specific drivers by explicitly increasing the use count of the module clock when the device is configured as a wakeup source. However, the proper way to prevent the device from being stopped is to inform this requirement to the genpd core, by setting the GENPD_FLAG_ACTIVE_WAKEUP flag. Note that this will only affect devices configured as wakeup sources.

2017-12-13soc/tegra: pmc: Consolidate Tegra186 supportThierry Reding4-175/+131
Move Tegra186 support to the consolidated PMC driver to reduce some of the duplication and also gain I/O pad functionality on the new SoC as a side-effect. Signed-off-by: Thierry Reding <treding@nvidia.com>
2017-12-13soc/tegra: pmc: Parameterize driverThierry Reding1-54/+121
Parameterize some aspects of the driver in preparation for Tegra186 PMC support. Initially the Tegra186 driver had been split off into an extra driver, but it turns out the backwards-compatibility break isn't as bad as originally assumed, so with a little parameterization the same code can be used to keep supporting all SoC generations.
