arm: use of_platform_default_populate() to populate

2016-06-23T20:00:39Z

Use helper of_platform_default_populate() in linux/of_platform when possible, instead of calling of_platform_populate() with the default match table.

ARM: versatile: move flash registration to the device tree

2016-04-04T08:33:16Z

This moves the boardfile definition of the flash memory in the Versatile board into the device tree. The flash was already defined with the property "arm,versatile-flash" which was not handled by the kernel: instead define it as compatible also with "cfi-flash" so it detects properly, and delete the corresponding boardfile code so we get a smooth transition. The old compatible string "arm,versatile-flash" is reused to indicate to the MTD physmap subsystem that this flash requires special VPP handling. (See separate patch.)

ARM: versatile: move restart to the device tree

2016-02-15T08:58:08Z

We have a power/reset driver for the Versatile family in drivers/power/reset so let's just activate that driver and use it and get rid of some non-DT remnants. Cc: Rob Herring Signed-off-by: Linus Walleij

ARM: versatile: convert to multi-platform

2015-12-15T22:54:48Z

Now that all the prerequisites are in place, we can enable Versatile boards for multi-platform kernels. Signed-off-by: Rob Herring Cc: Russell King Cc: Linus Walleij Signed-off-by: Arnd Bergmann

ARM: versatile: merge mach code into a single file

2015-12-15T22:54:43Z

With DT-only support now in place and most of the legacy code removed, the separation of core.c and versatile_dt.c makes little sense. The headers in mach include directory also have to move for multi-platform support, but with a single .c file the remaining definitions needed can also be moved into the versatile_dt.c. In the move, the system registers and IB2 registers are converted to run-time mappings and all register accesses converted to use readl/writel.

ARM: versatile: switch to DT only booting and remove legacy code

2015-12-15T22:53:21Z

With DT support for clocks, irqchips, timers, and PCI now in place, DT based booting has feature parity with non-DT legacy boot. The final piece is actually enabling common clock support on Versatile. Enabling full DT support requires either removing the old Versatile clock code, updating the legacy boot to use the common clock code, or making DT and legacy boot mutually exclusive. Given that removing legacy boot code is the goal anyway, I am going with the 1st option. Signed-off-by: Rob Herring Cc: Russell King Cc: Linus Walleij Cc: Mike Turquette Signed-off-by: Arnd Bergmann

ARM: versatile: add DT based PCI detection

2015-12-15T22:53:10Z

Disable the Versatile PCI DT node when no PCI backplane is detected. This will prevent the Versatile PCI driver from probing when PCI is not populated. Signed-off-by: Rob Herring Cc: Russell King Cc: Linus Walleij Signed-off-by: Arnd Bergmann

ARM: 8366/1: move Dual-Timer SP804 driver to drivers/clocksource

2015-06-02T08:58:18Z

The ARM Dual-Timer SP804 module is peripheral found not only on ARM32 platforms but also on ARM64 platforms. This patch moves the driver out of arch/arm to driver/clocksource so that it can be used on ARM64 platforms also.

ARM: 8365/1: introduce sp804_timer_disable and remove arm_timer.h inclusion

2015-06-02T08:58:18Z

The header asm/hardware/arm_timer.h is included in various machine specific files to access TIMER_CTRL and initialise to a known state. This patch introduces a new function sp804_timer_disable to disable the SP804 timers and uses the same for initialising the timers to known(off) state, thereby removing the dependency on the header asm/hardware/arm_timer.h This change is in prepartion to move sp804 timer support out of arch/arm so that it can be used on ARM64 platforms.

ARM: make arrays containing machine compatible strings const

2015-02-19T08:44:17Z

The definition static const char *axxia_dt_match[] __initconst = { ... defines a changable array of constant strings. That is you must not do: *axxia_dt_match[0] = 'k'; but axxia_dt_match[0] = "different string"; is fine. So the annotation __initconst is wrong and yields a compiler error when other really const variables are added with __initconst. As the struct machine_desc member dt_compat is declared as const char *const *dt_compat; making the arrays const is the better alternative over changing all annotations to __initdata.
