* pinctrl: single: create new gpio function rangeHaojian Zhuang2013-03-071-2/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since gpio driver could create gpio range in DTS, it could invoke pinctrl_request_gpio(). In the pinctrl-single driver, it needs to configure pins with gpio function mode. A new gpio function range should be created in DTS file in below. pinctrl-single,gpio-range = <phandle pin_offset nr_pins gpio_func>; range: gpio-range { #pinctrl-single,gpio-range-cells = <3>; }; The gpio-ranges property is used in gpio driver and the pinctrl-single,gpio-range property is used in pinctrl-single driver. 1. gpio-ranges is used for gpio driver in below. gpio-ranges = <phandle gpio_offset_in_chip pin_offset nr_pins> gpio-ranges = < &pmx0 0 89 1 &pmx0 1 89 1 &pmx0 2 90 1 &pmx0 3 90 1 &pmx0 4 91 1 &pmx0 5 92 1>; 2. gpio driver could get pin offset from gpio-ranges property. pinctrl-single driver could get gpio function mode from gpio_func that is stored in @gpiofuncs list in struct pcs_device. This new pinctrl-single,gpio-range is used as complement for gpio-ranges property in gpio driver.

* gpio: pl061: bind pinctrl by gpio requestHaojian Zhuang2013-03-071-0/+13
| | | | | | | | | | | | Add the pl061_gpio_request() to request pinctrl. Create the logic between pl061 gpio driver and pinctrl (pinctrl-single) driver. While a gpio pin is requested, it will request pinctrl driver to set that pin with gpio function mode. So pinctrl driver should append .gpio_request_enable() in pinmux_ops.

* pinctrl: check pinctrl ready for gpio rangeHaojian Zhuang2013-03-071-0/+36
| | | | | | | | | | | | | | | | | | | | pinctrl_get_device_gpio_range() only checks whether a certain GPIO pin is in gpio range. But maybe some GPIO pins don't have back-end pinctrl interface, it means that these pins are always configured as GPIO function. For example, gpio159 isn't related to back-end pinctrl device in Hi3620 while other GPIO pins are related to back-end pinctrl device. Append pinctrl_ready_for_gpio_range() that is used to check whether pinctrl device with GPIO range is ready. This function will be called after pinctrl_get_device_gpio_range() fails. If pinctrl device with GPIO range is found, it means that pinctrl device is already launched and a certain GPIO pin just don't have back-end pinctrl interface. Then pinctrl_request_gpio() shouldn't return -EPROBE_DEFER in this case. Signed-off-by: Haojian Zhuang <haojian.zhuang@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Meta hardware threads have 2 timers. The background timer (TXTIMER) is used as a free-running time base, and the interrupt timer (TXTIMERI) is used for the timer interrupt. Both counters traditionally count at approximately 1MHz. Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: John Stultz <johnstul@us.ibm.com> Cc: Thomas Gleixner <tglx@linutronix.de>

That commit was written under the assumption that some controllers may take a very long time to turn off their async and periodic schedules. It now appears that in fact the schedules do get turned off reasonably quickly, but some controllers occasionally leave the schedules' status bits turned on and consequently ehci-hcd can't tell that the schedules are off. VIA controllers in particular have this problem. ehci-hcd tells the hardware to turn off the async schedule, the schedule does get turned off, but the status bit remains on. Since the EHCI spec requires that the schedules not be re-enabled until the previous disable has taken effect, with an unlimited timeout the async schedule never gets turned back on. The resulting symptom is that the system is unable to communicate with USB devices.
