ARM: ux500: resume the second core properly

2017-03-02T16:53:17Z

The pen hold/release scheme was copied over to Ux500 from the ARM reference designs like most of these at the time. It is not needed at all, and was mostly removed in commit c00def71efd9 "ARM: ux500: simplify secondary CPU boot". However on the suspend/resume path and hot plug/unplug of CPUs, the .cpu_die() callback was still waiting for the pen to be released which made it spin forever and the second core never come back online after suspend/resume. Fix this by simply replacing the strange custom .cpu_die() with a oneline wfi() just like e.g. the qcom platform does. This fixes the issue and makes the second core come up properly after suspend/resume. As a side effect, this rids us of the completely surplus local setup.h and hotplug.c files, and we just compile this into platsmp.c with everything else SMP.

ARM: ux500: remove deleted file from Makefile

2017-02-07T19:24:28Z

Cleanup removed the file, but Makefile was overlooked. Purge there too. Fixes: 4b483ed0be8b ('ARM: ux500: cut some platform data') Signed-off-by: Olof Johansson

ARM: ux500: consolidate base platform files

2016-07-12T09:24:09Z

The cpu.c and cache-l2x0.c files hold only two or three simple functions each, and they are all called from the machine descriptors, so we can just move them all into the same file for simplicity and consistency. Signed-off-by: Arnd Bergmann Signed-off-by: Linus Walleij

ARM: ux500: move soc_id driver to drivers/soc

2016-07-12T09:24:09Z

As the ux500 id code is basically a standalone driver, we can move it out of the arch code into drivers/soc/ux500. This is a user-visible change, as it moves all the devices in sysfs from /sys/devices/soc0/ to /sys/devices/ and leaves the soc0 node as a separate device. Originally the idea was to put all on-chip devices under the soc node, and ux500 was the first platform to have this device, but later platforms almost all didn't follow that pattern, so this makes the platform do the same thing as everyone else. Since the platform is really obsolete now, I am optimistic that nothing will break after moving the devices around. As the SoC driver no longer has access to the private header files, I'm changing the code to instead look up the address of the backupram from devicetree, which is a good idea anyway. Finally, having a separate Kconfig symbol means the driver is now optional and could even be a loadable module rather than always being built-in if we allowed that for soc_device.

ARM: ux500: move ab8500_regulator_plat_data into driver

2016-07-12T09:23:50Z

There is only one instance of ab8500_regulator_platform_data, and it's safe to assume we won't ever merge another one, so it's rather pointless to pass it through multiple levels of platform data pointers. This moves the structure and everything referenced by it into the driver that uses it. Signed-off-by: Arnd Bergmann Acked-by: Mark Brown Signed-off-by: Linus Walleij

ARM/clocksource: use automatic DT probing for ux500 PRCMU

2015-12-01T21:37:02Z

The ARM core kernel already calls clocksource_of_init() so why go to all the trouble of locating and probing this node in the machine. CLOCKSOURCE_OF_DECLARE() will take care of it in the clocksource driver, and thus we can also get rid of the dangling header file Suggested-by: Arnd Bergmann Acked-by: Thomas Gleixner Acked-by: Daniel Lezcano Signed-off-by: Linus Walleij Signed-off-by: Arnd Bergmann

ARM: ux500: simplify secondary CPU boot

2015-08-06T08:11:44Z

This removes a lot of ancient cruft from the Ux500 SMP boot. Instead of the pen grab/release, just point the ROM to secondary_boot() and start the second CPU there, then send the IPI. Use our own SMP enable method. This enables us to remove the last static mapping and get both CPUs booting properly. Tested this and it just works.

ARM: ux500: Initial support for PM domains

2014-10-28T09:48:23Z

The ux500 SoC uses the generic PM domain and requires the domains to be specified through DT. Currently the genpd callbacks for handling power gating|ungating are implemented as dummy functions. To be able to enable those to perform PM domain gating/ungating, each device that resides in the VAPE domain must be properly handled from a runtime PM perspective.

ARM: ux500: Remove redundant board file for mmci platform data

2014-05-12T10:52:44Z

Since all platform data has been transfered to DT, we don't need the container for the mmci platform data anymore. Remove the file and the corresponding references to it's data. Signed-off-by: Ulf Hansson Acked-by: Linus Walleij
