soc: mtk-pmic-wrap: avoid integer overflow warning

2016-05-19T13:20:24Z

On ARM64, the mtk-pmic-wrap driver causes a harmless warning: mtk-pmic-wrap.c:1062:16: warning: large integer implicitly truncated to unsigned type [-Woverflow] mtk-pmic-wrap.c:1074:16: warning: large integer implicitly truncated to unsigned type [-Woverflow] mtk-pmic-wrap.c:1086:16: warning: large integer implicitly truncated to unsigned type [-Woverflow] .int_en_all = ~(BIT(31) | BIT(1)), The problem is that the result of the BIT() macro is an 'unsigned long', so taking the bitwise NOT operation of that results in an integer with the upper 32 bits all set and that cannot be assigned to a 'u32' variable without loss of information. This is harmless because we were never interested in the upper bits here anyway, so we can shut up the warning by adding a simple cast to 'u32'. Signed-off-by: Arnd Bergmann

Pull ARM SoC driver updates from Arnd Bergmann: "Driver updates for ARM SoCs, these contain various things that touch the drivers/ directory but got merged through arm-soc for practical reasons. For the most part, this is now related to power management controllers, which have not yet been abstracted into a separate subsystem, and typically require some code in drivers/soc or arch/arm to control the power domains. Another large chunk here is a rework of the NVIDIA Tegra USB3.0 support, which was surprisingly tricky and took a long time to get done. Finally, reset controller handling as always gets merged through here as well" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (97 commits) arm-ccn: Enable building as module soc/tegra: pmc: Add generic PM domain support usb: xhci: tegra: Add Tegra210 support usb: xhci: Add NVIDIA Tegra XUSB controller driver dt-bindings: usb: xhci-tegra: Add Tegra210 XUSB controller support dt-bindings: usb: Add NVIDIA Tegra XUSB controller binding PCI: tegra: Support per-lane PHYs dt-bindings: pci: tegra: Update for per-lane PHYs phy: tegra: Add Tegra210 support phy: Add Tegra XUSB pad controller support dt-bindings: phy: tegra-xusb-padctl: Add Tegra210 support dt-bindings: phy: Add NVIDIA Tegra XUSB pad controller binding phy: core: Allow children node to be overridden clk: tegra: Add interface to enable hardware control of SATA/XUSB PLLs drivers: firmware: psci: make two helper functions inline soc: renesas: rcar-sysc: Add support for R-Car H3 power areas soc: renesas: rcar-sysc: Add support for R-Car E2 power areas soc: renesas: rcar-sysc: Add support for R-Car M2-N power areas soc: renesas: rcar-sysc: Add support for R-Car M2-W power areas soc: renesas: rcar-sysc: Add support for R-Car H2 power areas ...

Pull ARM DT updates from Arnd Bergmann: "These are all the updates to device tree files for 32-bit platforms, which as usual makes up the bulk of the ARM SoC changes: 462 non-merge changesets, 450 files changed, 23340 insertions, 5216 deletions. The three platforms that are added with the "soc" branch are here as well, and we add some related machine files: - For Aspeed AST2400/AST2500, we get the evaluation platform and the Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC - For Oxnas 810SE, the Western Digital "My Book World Edition" is added as the only platform at the moment. - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7) are supported On the ARM Realview development platform, we now support all machines with device tree, previously only the board files were supported, which in turn will likely be removed soon.

2016-05-18T00:39:42Z

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for kernel cycle v4.7: Core infrastructural changes: - Support for natively single-ended GPIO driver stages. This means that if the hardware has registers to configure open drain or open source configuration, we use that rather than (as we did before) try to emulate it by switching the line to an input to get high impedance. This is also documented throughly in Documentation/gpio/driver.txt for those of you who did not understand one word of what I just wrote. - Start to do away with the unnecessarily complex and unitelligible ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from the time when the GPIO subsystem was unmaintained. Archs can now just select GPIOLIB and be done with it, cleanups to arches will trickle in for the next kernel. Some minor archs ACKed the changes immediately so these are included in this pull request. - Advancing the use of the data pointer inside the GPIO device for storing driver data by switching the PowerPC, Super-H Unicore and a few other subarches or subsystem drivers in ALSA SoC, Input, serial, SSB, staging etc to use it. - The initialization now reads the input/output state of the GPIO lines, so that each GPIO descriptor knows - if this callback is implemented - whether the line is input or output. This also reflects nicely in userspace "lsgpio". - It is now possible to name GPIO producer names, line names, from the device tree. (Platform data has been supported for a while). I bet we will get a similar mechanism for ACPI one of those days. This makes is possible to get sensible producer names for e.g. GPIO rails in "lsgpio" in userspace. New drivers: - New driver for the Loongson1. - The XLP driver now supports Broadcom Vulcan ARM64. - The IT87 driver now supports IT8620 and IT8628. - The PCA953X driver now supports Galileo Gen2. Driver improvements: - MCP23S08 was switched to use the gpiolib irqchip helpers and now also suppors level-triggered interrupts. - 74x164 and RCAR now supports the .set_multiple() callback - AMDPT was converted to use generic GPIO. - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994 support the new single ended callback for open drain and in some cases open source. - Implement the .get_direction() callback for a few more drivers like PL061, Xgene. Cleanups: - Paul Gortmaker combed through the drivers and de-modularized those who are not really modules. - Move the GPIO poweroff DT bindings to the power subdir where they belong. - Rename gpio-generic.c to gpio-mmio.c, which is much more to the point.
