unicore32/PCI: Remove pci=firmware command line parameter handling

2016-06-23T22:15:33Z

Remove support for the "pci=firmware" command line parameter, which was way to keep the kernel from changing any PCI BAR assignments. This was copied from ARM, but is not actually needed on unicore32. The corresponding ARM support was removed by 903589ca7165 ("ARM: 8554/1: kernel: pci: remove pci=firmware command line parameter handling"). Signed-off-by: Bjorn Helgaas

exit_thread: remove empty bodies

2016-05-21T00:58:30Z

Define HAVE_EXIT_THREAD for archs which want to do something in exit_thread. For others, let's define exit_thread as an empty inline.

Merge tag 'gpio-v4.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

2016-03-18T04:05:32Z

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for kernel v4.6. There is quite a lot of interesting stuff going on. The patches to other subsystems and arch-wide are ACKed as far as possible, though I consider things like per-arch as essentially a part of the GPIO subsystem so it should not be needed. Core changes: - The gpio_chip is now a *real device*. Until now the gpio chips were just piggybacking the parent device or (gasp) floating in space outside of the device model. We now finally make GPIO chips devices. The gpio_chip will create a gpio_device which contains a struct device, and this gpio_device struct is kept private. Anything that needs to be kept private from the rest of the kernel will gradually be moved over to the gpio_device. - As a result of making the gpio_device a real device, we have added resource management, so devm_gpiochip_add_data() will cut down on overhead and reduce code lines. A huge slew of patches convert almost all drivers in the subsystem to use this. - Building on making the GPIO a real device, we add the first step of a new userspace ABI: the GPIO character device. We take small steps here, so we first add a pure *information* ABI and the tool "lsgpio" that will list all GPIO devices on the system and all lines on these devices. We can now discover GPIOs properly from userspace. We still have not come up with a way to actually *use* GPIOs from userspace. - To encourage people to use the character device for the future, we have it always-enabled when using GPIO. The old sysfs ABI is still opt-in (and can be used in parallel), but is marked as deprecated. We will keep it around for the foreseeable future, but it will not be extended to cover ever more use cases. Cleanup: - Bjorn Helgaas removed a whole slew of per-architecture includes. This dates back to when GPIO was an opt-in feature and no shared library even existed: just a header file with proper prototypes was provided and all semantics were up to the arch to implement. These patches make the GPIO chip even more a proper device and cleans out leftovers of the old in-kernel API here and there. Still some cruft is left but it's very little now. - There is still some clamping of return values for .get() going on, but we now return sane values in the vast majority of drivers and the errorpath is sanitized. Some patches for powerpc, blackfin and unicore still drop in. - We continue to switch the ARM, MIPS, blackfin, m68k local GPIO implementations to use gpiochip_add_data() and cut down on code lines. - MPC8xxx is converted to use the generic GPIO helpers. - ATH79 is converted to use the generic GPIO helpers. New drivers: - WinSystems WS16C48 - Acces 104-DIO-48E - F81866 (a F7188x variant) - Qoric (a MPC8xxx variant) - TS-4800 - SPI serializers (pisosr): simple 74xx shift registers connected to SPI to obtain a dirt-cheap output-only GPIO expander. - Texas Instruments TPIC2810 - Texas Instruments TPS65218 - Texas Instruments TPS65912 - X-Gene (ARM64) standby GPIO controller" * tag 'gpio-v4.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (194 commits) Revert "Share upstreaming patches" gpio: mcp23s08: Fix clearing of interrupt. gpiolib: Fix comment referring to gpio_*() in gpiod_*() gpio: pca953x: Fix pca953x_gpio_set_multiple() on 64-bit gpio: xgene: Fix kconfig for standby GIPO contoller gpio: Add generic serializer DT binding gpio: uapi: use 0xB4 as ioctl() major gpio: tps65912: fix bad merge Revert "gpio: lp3943: Drop pin_used and lp3943_gpio_request/lp3943_gpio_free" gpio: omap: drop dev field from gpio_bank structure gpio: mpc8xxx: Slightly update the code for better readability gpio: mpc8xxx: Remove *read_reg and *write_reg from struct mpc8xxx_gpio_chip gpio: mpc8xxx: Fixup setting gpio direction output gpio: mcp23s08: Add support for mcp23s18 dt-bindings: gpio: altera: Fix altr,interrupt-type property gpio: add driver for MEN 16Z127 GPIO controller gpio: lp3943: Drop pin_used and lp3943_gpio_request/lp3943_gpio_free gpio: timberdale: Switch to devm_ioremap_resource() gpio: ts4800: Add IMX51 dependency gpiolib: rewrite gpiodev_add_to_list ...

arch: Set IORESOURCE_SYSTEM_RAM flag for System RAM

2016-01-30T08:49:57Z

Set IORESOURCE_SYSTEM_RAM in flags of resource ranges with "System RAM", "Kernel code", "Kernel data", and "Kernel bss". Note that: - IORESOURCE_SYSRAM (i.e. modifier bit) is set in flags when IORESOURCE_MEM is already set. IORESOURCE_SYSTEM_RAM is defined as (IORESOURCE_MEM|IORESOURCE_SYSRAM). - Some archs do not set 'flags' for children nodes, such as "Kernel code". This patch does not change 'flags' in this case.

unicore: gpio: Be sure to clamp return value

2016-01-25T17:02:26Z

As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1]. We do this by using the ret = !!(val) design pattern. Cc: Guan Xuetao Signed-off-by: Linus Walleij

Pull pwm updates from Thierry Reding: "This round contains a couple of new drivers for the Marvell Berlin family of SoCs, various SoCs from Renesas and Broadcom as well as the backlight PWM present on MediaTek SoCs. Further existing drivers are extended to support a wider range of hardware. The remaining patches are minor fixes and cleanups across the board. Note that one of the patches included in this pull request is against arch/unicore32. I've included it here because I couldn't get a response from Guan Xuetao and I consider the change low-risk.

unicore32: nb0916: Use PWM lookup table

2015-11-10T12:06:44Z

Use a PWM lookup table to provide the PWM to the pwm-backlight device. The driver has a legacy code path that is required only because boards still use the legacy method of requesting PWMs by global ID. Replacing these usages allows that legacy fallback to be removed.
