dt-bindings: leds: gpio: Add optional retain-state-shutdown property

2017-08-29T00:48:16+00:00

On Baseboard Management Controller (BMC) systems it's sometimes necessary for a LED to retain its state across a BMC reset (which is independent of the host system state). Add a devicetree property to describe this behaviour. The property would typically be used in conjunction with 'default-state = "keep"'.

Documentation: dt-bindings: aspeed-pwm-tacho cooling device.

2017-08-14T05:02:47+00:00

It's add support for cooling device creation to aspeed-pwm-tacho. Cooling device could be bound to a thermal zone for the thermal control.

Documentation: dt-bindings: Document bindings for ASPEED AST2400/AST2500 PWM and Fan tach controller device driver

2017-08-14T05:02:47+00:00

This binding provides interface for adding values related to ASPEED AST2400/2500 PWM and Fan tach controller support. The PWM controller can support upto 8 PWM output ports. The Fan tach controller can support upto 16 tachometer inputs.

dt-bindings: fsi: Add optional property no-scan-on-init

2017-08-08T12:59:53+00:00

Add an optional FSI master property 'no-scan-on-init. This can be specified to indicate that a master should not be automatically scanned at init time. This is required in cases where a scan could interfere with another FSI master on the same bus. OpenBMC-Staging-Count: 1 Signed-off-by: Christopher Bostic Signed-off-by: Joel Stanley

dt-bindings: max31785: Add use-stored-presence property

2017-08-01T04:09:03+00:00

It's a system design decision with regards to managing the default values of registers such as FAN_CONFIG_1_2. Do not assume the hardware is configured such as the fans are marked as installed, rather expose a devicetree property to inform the driver of whether it should treat the devicetree or the device state as canonical.

dt-bindings: watchdog: aspeed: External reset signal properties

2017-07-31T23:42:23+00:00

For the AST2500 and compatible watchdog controllers the external reset signal can be configured for push-pull or open-drain drive types, and in the case of open-drain driving, active low or high.

drivers/serial: Add driver for Aspeed virtual UART

2017-07-31T09:28:36+00:00

This change adds a driver for the 16550-based Aspeed virtual UART device. We use a similar process to the of_serial driver for device probe, but expose some VUART-specific functions through sysfs too. The VUART is two UART 'front ends' connected by their FIFO (no actual serial line in between). One is on the BMC side (management controller) and one is on the host CPU side. This driver is for the BMC side. The sysfs files allow the BMC userspace, which owns the system configuration policy, to specify at what IO port and interrupt number the host side will appear to the host on the Host <-> BMC LPC bus. It could be different on a different system (though most of them use 3f8/4). OpenPOWER host firmware doesn't like it when the host-side of the VUART's FIFO is not drained. This driver only disables host TX discard mode when the port is in use. We set the VUART enabled bit when we bind to the device, and clear it on unbind. We don't want to do this on open/release, as the host may be using this bit to configure serial output modes, which is independent of whether the devices has been opened by BMC userspace.
