This is commonly used on Android based devices, in order to reboot the device into fastboot or recovery mode.

As in sama5d3 or later chips, we don't have to shutdown the DDR controller before reset. Shutdown the DDR controller before reset is a workaround to avoid DDR signal driving the bus, but since sama5d3 and later chips there is no such a conflict. So in this patch: 1. the sama5d3 reset function only need to write the rstc register and return. 2. we can remove the code related with sama5d3 DDR controller as we don't use it at all.

We see an increasing number of non-modular drivers using modular_driver() type register functions. There are several downsides to letting this continue unchecked: - The code can appear modular to a reader of the code, and they won't know if the code really is modular without checking the Makefile and Kconfig to see if compilation is governed by a bool or tristate. - Coders of drivers may be tempted to code up an __exit function that is never used, just in order to satisfy the required three args of the modular registration function. - Non-modular code ends up including the <module.h> which increases CPP overhead that they don't need. - It hinders us from performing better separation of the module init code and the generic init code. So here we introduce similar macros for builtin drivers. Then we convert builtin drivers (controlled by a bool Kconfig) by making the following type of mapping: module_platform_driver() ---> builtin_platform_driver() module_platform_driver_probe() ---> builtin_platform_driver_probe(). The set of drivers that are converted here are just the ones that showed up as relying on an implicit include of <module.h> during a pending header cleanup. So we convert them here vs adding an include of <module.h> to non-modular code to avoid compile fails. Additonal conversions can be done asynchronously at any time. Once again, an unused module_exit function that is removed here appears in the diffstat as an outlier wrt all the other changes" * tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: drivers/clk: convert sunxi/clk-mod0.c to use builtin_platform_driver drivers/power: Convert non-modular syscon-reboot to use builtin_platform_driver drivers/soc: Convert non-modular soc-realview to use builtin_platform_driver drivers/soc: Convert non-modular tegra/pmc to use builtin_platform_driver drivers/cpufreq: Convert non-modular s5pv210-cpufreq.c to use builtin_platform_driver drivers/cpuidle: Convert non-modular drivers to use builtin_platform_driver drivers/platform: Convert non-modular pdev_bus to use builtin_platform_driver platform_device: better support builtin boilerplate avoidance

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This file depends on Kconfig options all of which are a bool, so we use the appropriate registration function, which avoids us relying on an implicit inclusion of <module.h> which we are doing currently. While this currently works, we really don't want to be including the module.h header in non-modular code, which we'd be forced to do, pending some upcoming code relocation from init.h into module.h. So we fix it now by using the non-modular equivalent.

But while the soc-level restarts are provided by the soc itself, gpio-restarts will most of the time be board-specfic and be used when some special board condition makes the soc-level restart only a second choice. The problem at hand manifested itself on the rk3288-veyron devices. While the soc-level restart can sucessfully restart all other rockchip boards I have, the veyron devices use an external restart mechanism that seems to not only reset the soc but also some external needed components. With both restart handlers having priority 128 in my tests the soc-specific variant took precedent in all cases. While it could restart the soc sucessfully in all cases, firmware then got an issue when talking to an external component, resulting in the device being put into recovery mode. So, give the board-specific restart handler a slight push and move it to priority 129 to make it more important than the generic soc-specific restart-handler.

| * power: reset: Add MFD_SYSCON depends for brcmstbFlorian Fainelli2015-05-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | The Broadcom STB reboot driver depends on MFD_SYSCON, it uses syscon_regmap_lookup_by_phandle() which will not lookup syscon phandles if MFD_SYSCON is disabled, and instead will return -ENOSYS since it is turned into an inline stub.

| * power: reset: ltc2952: Remove bogus hrtimer_start() return value checksThomas Gleixner2015-04-301-15/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The return value of hrtimer_start() tells whether the timer was inactive or active already when hrtimer_start() was called. The code emits a bogus warning if the timer was active already claiming that the timer could not be started. Remove it.
