usb: Make sure usb/phy/of gets built-in

2017-05-20T12:28:35Z

commit 3d6159640da9c9175d1ca42f151fc1a14caded59 upstream. DWC3 driver uses of_usb_get_phy_mode() which is implemented in drivers/usb/phy/of.c and in bare minimal configuration it might not be pulled in kernel binary. In case of ARC or ARM this could be easily reproduced with "allnodefconfig" +CONFIG_USB=m +CONFIG_USB_DWC3=m.

ipmi: add an Aspeed BT IPMI BMC driver

2016-09-30T00:05:06Z

This patch adds a simple device driver to expose the iBT interface on Aspeed SOCs (AST2400 and AST2500) as a character device. Such SOCs are commonly used as BMCs (BaseBoard Management Controllers) and this driver implements the BMC side of the BT interface. The BT (Block Transfer) interface is used to perform in-band IPMI communication between a host and its BMC. Entire messages are buffered before sending a notification to the other end, host or BMC, that there is data to be read. Usually, the host emits requests and the BMC responses but the specification provides a mean for the BMC to send SMS Attention (BMC-to-Host attention or System Management Software attention) messages. For this purpose, the driver introduces a specific ioctl on the device: 'BT_BMC_IOCTL_SMS_ATN' that can be used by the system running on the BMC to signal the host of such an event. The device name defaults to '/dev/ipmi-bt-host' Signed-off-by: Alistair Popple Signed-off-by: Jeremy Kerr Signed-off-by: Joel Stanley [clg: - checkpatch fixes - added a devicetree binding documentation - replace 'bt_host' by 'bt_bmc' to reflect that the driver is the BMC side of the IPMI BT interface - renamed the device to 'ipmi-bt-host' - introduced a temporary buffer to copy_{to,from}_user - used platform_get_irq() - moved the driver under drivers/char/ipmi/ but kept it as a misc device - changed the compatible cell to "aspeed,ast2400-bt-bmc" ] Signed-off-by: Cédric Le Goater Acked-by: Arnd Bergmann [clg: - checkpatch --strict fixes - removed the use of devm_iounmap, devm_kfree in cleanup paths - introduced an atomic-t to limit opens to 1 - introduced a mutex to protect write/read operations] Acked-by: Rob Herring Signed-off-by: Cédric Le Goater Signed-off-by: Corey Minyard

clk: probe common clock drivers earlier

2016-09-23T11:00:04Z

Several SoCs implement platform drivers for clocks rather than CLK_OF_DECLARE(). Clocks should come earlier because they are prerequisites for many of other drivers. It will help to mitigate EPROBE_DEFER issues. Also, drop the comment since it does not carry much value. Signed-off-by: Masahiro Yamada Acked-by: Michael Turquette Signed-off-by: Greg Kroah-Hartman

2016-07-27T02:16:01Z

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.8 kernel cycle. The big news is the completion of the chardev ABI which I'm very happy about and apart from that it's an ordinary, quite busy cycle. The details are below. The patches are tested in linux-next for some time, patches to other subsystem mostly have ACKs. I got overly ambitious with configureing lines as input for IRQ lines but it turns out that some controllers have their interrupt-enable and input-enabling in orthogonal settings so the assumption that all IRQ lines are input lines does not hold. Oh well, revert and back to the drawing board with that. Core changes: - The big item is of course the completion of the character device ABI. It has now replaced and surpassed the former unmaintainable sysfs ABI: we can now hammer (bitbang) individual lines or sets of lines and read individual lines or sets of lines from userspace, and we can also register to listen to GPIO events from userspace. As a tie-in we have two new tools in tools/gpio: gpio-hammer and gpio-event-mon that illustrate the proper use of the new ABI. As someone said: the wild west days of GPIO are now over. - Continued to remove the pointless ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB Kconfig symbols. I'm patching hexagon, openrisc, powerpc, sh, unicore, ia64 and microblaze. These are either ACKed by their maintainers or patched anyways after a grace period and no response from maintainers. Some archs (ARM) come in from their trees, and others (x86) are still not fixed, so I might send a second pull request to root it out later in this merge window, or just defer to v4.9. - The GPIO tools are moved to the tools build system. New drivers: - New driver for the MAX77620/MAX20024. - New driver for the Intel Merrifield. - Enabled PCA953x for the TI PCA9536. - Enabled PCA953x for the Intel Edison. - Enabled R8A7792 in the RCAR driver. Driver improvements: - The STMPE and F7188x now supports the .get_direction() callback. - The Xilinx driver supports setting multiple lines at once. - ACPI support for the Vulcan GPIO controller. - The MMIO GPIO driver supports device tree probing. - The Acer One 10 is supported through the _DEP ACPI attribute. Cleanups: - A major cleanup of the OF/DT support code. It is way easier to read and understand now, probably this improves performance too. - Drop a few redundant .owner assignments. - Remove CLPS711x boardfile support: we are 100% DT" * tag 'gpio-v4.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (67 commits) MAINTAINERS: Add INTEL MERRIFIELD GPIO entry gpio: dwapb: add missing fwnode_handle_put() in dwapb_gpio_get_pdata() gpio: merrifield: Protect irq_ack() and gpio_set() by lock gpio: merrifield: Introduce GPIO driver to support Merrifield gpio: intel-mid: Make it depend to X86_INTEL_MID gpio: intel-mid: Sort header block alphabetically gpio: intel-mid: Remove potentially harmful code gpio: rcar: add R8A7792 support gpiolib: remove duplicated include from gpiolib.c Revert "gpio: convince line to become input in irq helper" gpiolib: of_find_gpio(): Don't discard errors gpio: of: Allow overriding the device node gpio: free handles in fringe cases gpio: tps65218: Add platform_device_id table gpio: max77620: get gpio value based on direction gpio: lynxpoint: avoid potential warning on error path tools/gpio: add install section tools/gpio: move to tools buildsystem gpio: intel-mid: switch to devm_gpiochip_add_data() gpio: 74x164: Use spi_write() helper instead of open coding ...

leds: Only descend into leds directory when CONFIG_NEW_LEDS is set
