2019-06-05soc/tegra: fuse: Do not log error message on deferred probeThierry Reding1-2/+4
Recent changes have made it much more probable that clocks are not available yet when the FUSE driver is first probed. However, that is a situation that the driver can cope with just fine. To avoid confusion, don't output an error when this happens. Signed-off-by: Thierry Reding <treding@nvidia.com>

2019-05-20soc: fsl: qbman_portals: add APIs to retrieve the probing statusLaurentiu Tudor2-8/+33
Add a couple of new APIs to check the probing status of the required cpu bound qman and bman portals: 'int bman_portals_probed()' and 'int qman_portals_probed()'. They return the following values. * 1 if qman/bman portals were all probed correctly * 0 if qman/bman portals were not yet probed * -1 if probing of qman/bman portals failed Portals are considered successful probed if no error occurred during the probing of any of the portals and if enough portals were probed to have one available for each cpu. The error handling paths were slightly rearranged in order to fit this new functionality without being too intrusive. Drivers that use qman/bman portal driver services are required to use these APIs before calling any functions exported by these drivers or otherwise they will crash the kernel.

Pull more power management updates from Rafael Wysocki: "These fix a recent regression causing kernels built with CONFIG_PM unset to crash on systems that support the Performance and Energy Bias Hint (EPB), clean up the cpufreq core and some users of transition notifiers and introduce a new power domain flag into the generic power domains framework (genpd). Specifics: - Fix recent regression causing kernels built with CONFIG_PM unset to crash on systems that support the Performance and Energy Bias Hint (EPB) by avoiding to compile the EPB-related code depending on CONFIG_PM when it is unset (Rafael Wysocki). - Clean up the transition notifier invocation code in the cpufreq core and change some users of cpufreq transition notifiers accordingly (Viresh Kumar). - Change MAINTAINERS to cover the schedutil governor as part of cpufreq (Viresh Kumar). - Simplify cpufreq_init_policy() to avoid redundant computations (Yue Hu). - Add explanatory comment to the cpufreq core (Rafael Wysocki). - Introduce a new flag, GENPD_FLAG_RPM_ALWAYS_ON, to the generic power domains (genpd) framework along with the first user of it (Leonard Crestez)" * tag 'pm-5.2-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: soc: imx: gpc: Use GENPD_FLAG_RPM_ALWAYS_ON for ERR009619 PM / Domains: Add GENPD_FLAG_RPM_ALWAYS_ON flag cpufreq: Update MAINTAINERS to include schedutil governor cpufreq: Don't find governor for setpolicy drivers in cpufreq_init_policy() cpufreq: Explain the kobject_put() in cpufreq_policy_alloc() cpufreq: Call transition notifier only once for each policy x86: intel_epb: Take CONFIG_PM into account

2019-05-01soc: ti: Add MSI domain bus support for Interrupt AggregatorLokesh Vutla3-0/+153
With the system coprocessor managing the range allocation of the inputs to Interrupt Aggregator, it is difficult to represent the device IRQs from DT. The suggestion is to use MSI in such cases where devices wants to allocate and group interrupts dynamically. Create a MSI domain bus layer that allocates and frees MSIs for a device. APIs that are implemented: - ti_sci_inta_msi_create_irq_domain() that creates a MSI domain - ti_sci_inta_msi_domain_alloc_irqs() that creates MSIs for the specified device and resource. - ti_sci_inta_msi_domain_free_irqs() frees the irqs attached to the device. - ti_sci_inta_msi_get_virq() for getting the virq attached to a specific event.

2019-04-30soc: sunxi: Fix missing dependency on REGMAP_MMIOSamuel Holland1-0/+1
When enabling ARCH_SUNXI from allnoconfig, SUNXI_SRAM is enabled, but not REGMAP_MMIO, so the kernel fails to link with an undefined reference to __devm_regmap_init_mmio_clk. Select REGMAP_MMIO, as suggested in drivers/base/regmap/Kconfig. This creates the following dependency loop: drivers/of/Kconfig:68: symbol OF_IRQ depends on IRQ_DOMAIN kernel/irq/Kconfig:63: symbol IRQ_DOMAIN is selected by REGMAP drivers/base/regmap/Kconfig:7: symbol REGMAP default is visible depending on REGMAP_MMIO drivers/base/regmap/Kconfig:39: symbol REGMAP_MMIO is selected by SUNXI_SRAM drivers/soc/sunxi/Kconfig:4: symbol SUNXI_SRAM is selected by USB_MUSB_SUNXI drivers/usb/musb/Kconfig:63: symbol USB_MUSB_SUNXI depends on GENERIC_PHY drivers/phy/Kconfig:7: symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3 drivers/phy/broadcom/Kconfig:29: symbol PHY_BCM_NS_USB3 depends on MDIO_BUS drivers/net/phy/Kconfig:12: symbol MDIO_BUS default is visible depending on PHYLIB drivers/net/phy/Kconfig:181: symbol PHYLIB is selected by ARC_EMAC_CORE drivers/net/ethernet/arc/Kconfig:18: symbol ARC_EMAC_CORE is selected by ARC_EMAC drivers/net/ethernet/arc/Kconfig:24: symbol ARC_EMAC depends on OF_IRQ To fix the circular dependency, make USB_MUSB_SUNXI select GENERIC_PHY instead of depending on it. This matches the use of GENERIC_PHY by all but two other drivers.

This modernizes the IXP4xx platform and adds initial Device Tree Support. We migrate to MULTI_IRQ_HANDLER, bumps the IRQs to offset 16, converts to SPARSE_IRQ, then we add proper subsystem drivers in each subsystem for irqchip, GPIO and clocksource and switch over to using these new drivers. Next we modernize the NPE and QMGR drivers and push them down into drivers/soc. This has been tested on the IXP4xx NSLU2 and the Gateworks GW2358-4. * tag 'ixp4xx-for-armsoc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik: (31 commits) ARM: dts: Add queue manager and NPE to the IXP4xx DTSI soc: ixp4xx: qmgr: Add DT probe code soc: ixp4xx: qmgr: Add DT bindings for IXP4xx qmgr soc: ixp4xx: npe: Add DT probe code soc: ixp4xx: Add DT bindings for IXP4xx NPE soc: ixp4xx: qmgr: Pass resources soc: ixp4xx: Remove unused functions soc: ixp4xx: Uninline several functions soc: ixp4xx: npe: Pass addresses as resources ARM: ixp4xx: Turn the QMGR into a platform device ARM: ixp4xx: Turn the NPE into a platform device ARM: ixp4xx: Move IXP4xx QMGR and NPE headers ARM: ixp4xx: Move NPE and QMGR to drivers/soc ARM: dts: Add some initial IXP4xx device trees ARM: ixp4xx: Add device tree boot support ARM: ixp4xx: Add DT bindings gpio: ixp4xx: Add OF probing support gpio: ixp4xx: Add DT bindings clocksource/drivers/ixp4xx: Add OF initialization support clocksource/drivers/ixp4xx: Add DT bindings ...
