* clk: select CLKDEV_LOOKUP from COMMON_CLKAhmad Fatoum2024-01-191-1/+0
| | | | | | | | | | All platforms that select COMMON_CLK also select CLKDEV_LOOKUP, therefore just select it in drivers/clk/Kconfig and drop the CLKDEV_LOOKUP all over the place.

* Rename struct device_d to deviceSascha Hauer2023-01-103-13/+13
| | | | | | | | | | | | | The '_d' suffix was originally introduced in case we want to import Linux struct device as a separate struct into barebox. Over time it became clear that this won't happen, instead barebox struct device_d is basically the same as Linux struct device. Rename the struct name accordingly to make porting Linux code easier.

* clocksource: assign non-zero priorities to all clocksourcesAhmad Fatoum2022-04-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most barebox clocksources have a zero priority and if multiple of them exist, but no higher priority ones, the first to call init_clock wins. Some supported boards like the Raspberry Pi additionally depended on initcall ordering to favor one zero-priority clocksource over another. With the move to deep probe and with Commit b641580deb8c ("of: platform: Ensure timers are probed early"), device tree blob iteration order could now dictate which clocksource is ultimately used. This led to a 20 times slower clock source being chosen on the Raspberry Pi, because the ARM architected timer was taken instead of the bcm2835 timer. Fix the root cause by assigning priorities to all clocksource drivers. Priorities chosen are: 50: device_initcall 60: coredevice_initcall 70: postcore_initcall 80: core_initcall These priorities are all below 100, which was previously the lowest positive priority and as they are positive, they win against the dummy clocksource. This should ensure no priority inversion happens.

| * restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.
