2015-11-23	d9ba9c9 Browse files » reset: Add gpio reset support ... If a device has the reset-gpios property we can support this through the reset controller API, so drivers do not have to open code the support for this property each time themselves as done a few dozen times in the kernel.

	00c8cfb Browse files » reset: Allow dummy reset lines ... Treat NULL as a dummy reset line which is returned by the reset core when there is no reset line connected to a device (that is, no reset is described in the device tree). With this consumers can just use the reset functions without having to check for existence. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 23 Nov 2015
	42c797b Browse files » video: pwm-backlight: Honour discrete brightness levels from dt ... If probed from device tree we have an array of pwm duty cycle levels in the brightness-levels property. Although the driver parsed the property, the values have been ignored. Make use of these flags so that the driver can work for example with inverted PWMs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 23 Nov 2015

	7454e17 Browse files » net: usb: asix: make rx_fixup ax_skb buffer aligned ... ax_skb receive buffer unalignment leads to consequent unalignment data access in network stack routines, especially in net_checksum(). By-turn unalignment data accesses lead to performance penalty. Moreover on classic MIPS CPUs without hardware unalignment access support this leads to undesirable exceptions. At the moment barebox on MIPS can't parry these unalignment access exceptions, so the Asix USB Ethernet chips, that need receive fixup workaround, are completely unusable on MIPS without this patch.

Marvell NAND controller allows to enable an Auto Read Status feature that will automatically monitor NAND status during Erase and Program operations.
