PCI: dwc: Remove dependency of designware on CONFIG_PCI

2017-02-21T21:00:26Z

CONFIG_PCI is used to enable host mode PCI. In preparation for adding endpoint mode support to designware driver, remove the dependency of designware on CONFIG_PCI and make only the host-specific part depend on CONFIG_PCI. Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Bjorn Helgaas

ptp_clock: Allow for it to be optional

2016-11-16T08:26:34Z

In order to break the hard dependency between the PTP clock subsystem and ethernet drivers capable of being clock providers, this patch provides simple PTP stub functions to allow linkage of those drivers into the kernel even when the PTP subsystem is configured out. Drivers must be ready to accept NULL from ptp_clock_register() in that case. And to make it possible for PTP to be configured out, the select statement in those driver's Kconfig menu entries is converted to the new "imply" statement. This way the PTP subsystem may have Kconfig dependencies of its own, such as POSIX_TIMERS, without having to make those ethernet drivers unavailable if POSIX timers are cconfigured out. And when support for POSIX timers is selected again then the default config option for PTP clock support will automatically be adjusted accordingly. The pch_gbe driver is a bit special as it relies on extra code in drivers/ptp/ptp_pch.c. Therefore we let the make process descend into drivers/ptp/ even if PTP_1588_CLOCK is unselected.

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
