2017-09-25irqchip: bcm2836: Move SMP startup code to arch/arm (v2)Stefan Wahren1-1/+5
In order to easily provide SMP for BCM2837 on 32-bit and 64-bit the SMP startup code was placed in irq-bcm2836. That's not the right approach. So move this code where it belongs.

2017-09-25clk: bcm2835: remove remains from stub clk driverDanilo Krummrich1-7/+0
This commit removes the fixed clocks introduced as a stub clock driver added with commit 75fabc3f6448 ("ARM: bcm2835: add stub clock driver"). Originally they were used to drive the AMBA bus and PL011 uart driver. Now these clocks are derived by the CPRMAN clock driver and configured in DT. Additionally, get rid of init_machine function in bcm2835 board file as there's nothing to do any longer.

2016-06-23arm: Remove unnecessary of_platform_populate with default match tableKefeng Wang1-10/+0
After patch "of/platform: Add common method to populate default bus", it is possible for arch code to remove unnecessary callers of of_platform_populate with default match table.

2015-12-22ARM: bcm2835: Add a compat string for bcm2836 machine probeEric Anholt1-0/+5
Supporting the 2836 requires using the new interrupt controller, which we have support for. Signed-off-by: Eric Anholt <eric@anholt.net>
2015-05-14ARM: bcm2835: Move the restart/power_off handling to the WDT driverEric Anholt1-73/+0
Since the WDT is what's used to drive restart and power off, it makes more sense to keep it there, where the regs are already mapped and definitions for them provided. Note that this means you may need to add CONFIG_BCM2835_WDT to retain functionality of your kernel.

2015-05-14ARM: bcm2835: Skip doing our own iotable_init() initializationEric Anholt1-17/+0
The only thing we were using this 16MB mapping of IO peripherals for was the uart's early debug mapping. If we just drop the map_io hook, the kernel will call debug_ll_io_init() for us, which maps the single page needed for the device.

2014-02-24ARM: bcm2835: Move to mach-bcm directoryMarkus Mayer1-0/+137
Move the bcm2835 board file into the mach-bcm directory. This allows us to get rid of the mach-bcm2835 directory with the associated Kconfig and Makefile.
