2013-04-23pm: mach-hs: workaround, reinit uart when 'no_console_suspend'topic-suspend-resume-m3Guodong Xu
If 'no_consle_suspend' is set in kernel cmdline, debuguart needs to be reinitialized when system resumes. If 'no_console_suspend' is not set, reinitialization is not required. Note: this is only a workaround way. To solve the issue, either we don't shutdown some resources in serail driver's suspend; or we need to dynamically find out which uart is being used as console (here we hardcoded it as uart0).

While hi6421 SoC interrupt occurs, it always locks spinlock even calling child irq handler. If child irq handler accesses pmic registers, it will be dead lock since accessing function also uses spinlock. Signed-off-by: Haojian Zhuang <haojian.zhuang@linaro.org>

Avoid to use mutex lock in rmw operation. Use spin lock with irq disabled instead.

2013-03-13pinctrl: check pinctrl ready for gpio rangeHaojian Zhuang
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>
