2018-06-26	edb4379 Browse files » watchdog: rave-sp-wdt: Explicitly access EEPROM for bootsource ... RAVE SP firmware versions found on RDU2 provide decicated bootsource manipulation commands, which, under the hood, are just thin wrappers around write/read to a particular location in EEPROM. Unfortunately, RAVE SP firmware found on RDU1, does not provide any dedicated bootsource commands and its users are expected to access EEPROM directly. In order to avoid having separate code paths for handling those two cases, convert the code to access EEPROM directly via NVMEM API.

	9d7d333 Browse files » usb: imx: implement support for limiting host to full speed ... This is needed when host is known to not work properly in high speed mode. In linux, chipidea driver supports 'maximum-speed' device tree property. When that is set to "full-speed", driver sets PFSC bit in PORTSC register, which disallows use of high speed mode. This patch implements same support for barebox. Important technical detail is that PFSC bit is cleared by port reset, thus setting it has to be done in ehci->init() callback which is called after ehci_reset().

While this is a fine default for PWM backlights, a user might wish to change this slew time to meet other constraints or even completely disable it for some backlight devices. Add a parameter and provide the default value from the backlight device.

If an attached bb device was removed before the actual mtd device the code would try due to a missing pointer reset to access the no more present bb device handle which leads to a page fault.
