PM / OPP: Remove useless check

2016-05-04T23:42:19Z

Regulators are optional for devices using OPPs and the OPP core shouldn't be printing any errors for such missing regulators. It was fine before the commit 0c717d0f9cb4, but that failed to update this part of the code to remove an 'always true' check and an extra unwanted print message. Fix that now.

device property: Avoid potential dereferences of invalid pointers

2016-04-27T21:40:02Z

Since fwnode may hold ERR_PTR(-ENODEV) or it may be NULL, the fwnode type checks is_of_node(), is_acpi_node() and is is_pset_node() need to consider it. Using IS_ERR_OR_NULL() to check it.

regmap: spmi: Fix regmap_spmi_ext_read in multi-byte case

2016-04-15T09:11:45Z

Specifically for the case of reads that use the Extended Register Read Long command, a multi-byte read operation is broken up into 8-byte chunks. However the call to spmi_ext_register_readl() is incorrectly passing 'val_size', which if greater than 8 will always fail. The argument should instead be 'len'.

PM / wakeirq: fix wakeirq setting after wakup re-configuration from sysfs

2016-04-07T20:23:47Z

Now wakeirq stops working for device if wakeup option for this device will be reconfigured through sysfs, like: echo disabled > /sys/devices/platform/extcon_usb1/power/wakeup echo enabled > /sys/devices/platform/extcon_usb1/power/wakeup Once above set of commands is executed the device's wakeup_source opject will be recreated and dev->power.wakeup->wakeirq field will contain NULL. As result, device_wakeup_arm_wake_irqs() will not arm wakeirq for the affected device. Hece, lets try to fix it in the following way: check for dev->wakeirq field when device_wakeup_attach() is called and if !NULL re-attach wakeirq to the device Signed-off-by: Grygorii Strashko Acked-by: Tony Lindgren Signed-off-by: Rafael J.

regmap: mmio: Explicitly say little endian is the defualt in the bus config

2016-03-31T20:41:12Z

Otherwise the DT parsing will default to big endian if nothing is specified. Reported-by: Krzysztof Kozlowski Signed-off-by: Mark Brown

regmap: mmio: Parse endianness definitions from DT

2016-03-30T15:46:15Z

Since we changed to do formatting in the bus we now skip all the format parsing that the core does for its data marshalling code. This means that we skip the DT parsing it does which breaks some systems, we need to add an explict call in the MMIO code to do this.

regmap: Fix implicit inclusion of device.h

2016-03-30T15:46:11Z

internal.h is using dev_name() but doesn't include device.h which defines it. Add an explicit include to avoid build problems due to this. Tested-by: Alexander Stein Signed-off-by: Mark Brown
