2017-02-07ARM: ux500: cut some platform dataLinus Walleij1-16/+0
This platform data is revoked: the drivers are getting the DMA configuration from the device tree, it has been done like that since the DMA support was merged and this data has not been used since. The remaining auxdata is also unused. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2016-07-12ARM: ux500: consolidate base platform filesArnd Bergmann1-0/+87
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.

2016-07-12ARM: ux500: move soc_id driver to drivers/socArnd Bergmann1-4/+2
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.

2016-07-12ARM: ux500: call ux500_setup_id laterArnd Bergmann1-8/+0
ux500_setup_id is currently called from u8500_map_io(), which is really early, but nothing relies on the ID any more, other than a printk message that is not really all that important to have early during boot. If we move the call to ux500_setup_id() into ux500_soc_device_init(), that file becomes usuable almost entirely standalone, and we can kill off the u8500_map_io() callback as it just does the default debug_ll_io_init() now.

2016-07-12ARM: ux500: consolidate soc_device code in id.cArnd Bergmann1-27/+1
Nothing else uses the global dbx500_asic_id structure, so we can merge the two small files that reference it into one. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-07-12ARM: ux500: move l2x0 init to .init_irqArnd Bergmann1-1/+2
The generic IRQ init function also enables the l2 cache implicitly when the machine descriptor sets an .l2c_aux_mask. Let's use that on ux500 and remove the ux500_l2x0_init() along with the cpu_is_u8500_family checks.

2016-07-12mfd: db8500 stop passing around platform dataArnd Bergmann1-15/+2

2016-07-12ARM: ux500: move ab8500_regulator_plat_data into driverArnd Bergmann1-2/+0
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.

2015-08-06ARM: ux500: simplify secondary CPU bootLinus Walleij1-1/+0
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.

Get rid of all the static assignments everywhere, delete it from the driver, platform data and the board files in one swift strike.
