reset: intel: add unspecified HAS_IOMEM dependency

2020-02-10T10:11:55Z

Currently CONFIG_RESET_INTEL_GW=y implicitly depends on CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get the following build error: /usr/bin/ld: drivers/reset/reset-intel-gw.o: in function `intel_reset_probe': drivers/reset/reset-intel-gw.c:185: undefined reference to `devm_platform_ioremap_resource' Fix the build error by adding the unspecified dependency.

Reset controller updates for v5.6 This tag adds support for the Nuvoton NPCM, Intel Gatway SoC, and Broadcom BCM7216 RESCAL reset controllers, adds missing SCSSI reset controls for newer Uniphier SoCs, aligns the program flow in the devm_reset_controller_register, __devm_reset_control_get, and devm_reset_control_array_get functions for better consistency, and allows to build the Qcom AOSS reset driver as a module. This is based on v5.5-rc3 because the core patch depends on commit db23808615e2 ("reset: Do not register resource data for missing resets"). * tag 'reset-for-5.6' of git://git.pengutronix.de/pza/linux: reset: qcom-aoss: Allow CONFIG_RESET_QCOM_AOSS to be a tristate reset: Add Broadcom STB RESCAL reset controller dt-bindings: reset: Document BCM7216 RESCAL reset controller reset: intel: Add system reset controller driver dt-bindings: reset: Add YAML schemas for the Intel Reset controller reset: uniphier: Add SCSSI reset control for each channel reset: Align logic and flow in managed helpers reset: npcm: add NPCM reset controller driver dt-bindings: reset: Add binding constants for NPCM7xx reset controller dt-bindings: reset: add NPCM reset controller documentation Link: https://lore.kernel.org/r/dbbb2ca7490a0146d9ba632fd4d9f38063e03e9f.camel@pengutronix.de Signed-off-by: Olof Johansson

Merge tag 'cpuidle_psci-v5.5-rc4' of git://git.linaro.org/people/ulf.hansson/linux-pm into arm/drivers

2020-01-08T18:26:29Z

Initial support for hierarchical CPU arrangement, managed by PSCI and its corresponding cpuidle driver. This support is based upon using the generic PM domain, which already supports devices belonging to CPUs. Finally, these is a DTS patch that enables the hierarchical topology to be used for the Qcom 410c Dragonboard, which supports the PSCI OS-initiated mode. * tag 'cpuidle_psci-v5.5-rc4' of git://git.linaro.org/people/ulf.hansson/linux-pm: (611 commits) arm64: dts: Convert to the hierarchical CPU topology layout for MSM8916 cpuidle: psci: Add support for PM domains by using genpd PM / Domains: Introduce a genpd OF helper that removes a subdomain cpuidle: psci: Support CPU hotplug for the hierarchical model cpuidle: psci: Manage runtime PM in the idle path cpuidle: psci: Prepare to use OS initiated suspend mode via PM domains cpuidle: psci: Attach CPU devices to their PM domains cpuidle: psci: Add a helper to attach a CPU to its PM domain cpuidle: psci: Support hierarchical CPU idle states cpuidle: psci: Simplify OF parsing of CPU idle state nodes cpuidle: dt: Support hierarchical CPU idle states of: base: Add of_get_cpu_state_node() to get idle states for a CPU node firmware: psci: Export functions to manage the OSI mode dt: psci: Update DT bindings to support hierarchical PSCI states cpuidle: psci: Align psci_power_state count with idle state count Linux 5.5-rc4 locks: print unsigned ino in /proc/locks riscv: export flush_icache_all to modules riscv: reject invalid syscalls below -1 riscv: fix compile failure with EXPORT_SYMBOL() & !MMU ...

reset: qcom-aoss: Allow CONFIG_RESET_QCOM_AOSS to be a tristate

2020-01-08T09:26:14Z

Allow CONFIG_RESET_QCOM_AOSS to be set as as =m to allow for the driver to be loaded from a modules. Also replaces the builtin_platform_driver() line with module_platform_driver() and adds a MODULE_DEVICE_TABLE() entry.

reset: Add Broadcom STB RESCAL reset controller

2020-01-06T09:02:03Z

On BCM7216 there is a special purpose reset controller named RESCAL (reset calibration) which is necessary for SATA and PCIe0/1 to operate correctly. This commit adds support for such a reset controller to be available. Signed-off-by: Jim Quinlan Signed-off-by: Florian Fainelli Signed-off-by: Philipp Zabel

reset: intel: Add system reset controller driver

2020-01-03T10:01:27Z

Add driver for the reset controller present on Intel Gateway SoCs for performing reset management of the devices present on the SoC. Driver also registers a reset handler to peform the entire device reset. Signed-off-by: Dilip Kota Signed-off-by: Philipp Zabel

reset: uniphier: Add SCSSI reset control for each channel

2020-01-02T11:25:05Z

SCSSI has reset controls for each channel in the SoCs newer than Pro4, so this adds missing reset controls for channel 1, 2 and 3. And more, this moves MCSSI reset ID after SCSSI.

reset: Align logic and flow in managed helpers

2020-01-02T11:25:05Z

__devm_reset_control_get() and devm_reset_control_array_get() are very similar, but they do not look similar, due to inverted logic. Make them more similar, following the "bail out early" paradigm. Adjust the logic and flow in devm_reset_controller_register() to match the two other functions. Signed-off-by: Geert Uytterhoeven Signed-off-by: Philipp Zabel
