* ARM: spear: move all files to mach-spearArnd Bergmann2013-03-121-430/+0
| | | | | | | | | There are no conflicting files between the three mach-spear* directories and plat-spear any more, so we can now move all file to a common mach-spear directory. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>
* ARM: spear: make spear3xx/6xx mach/spear.h files identicalArnd Bergmann2013-03-121-6/+6
| | | | | | | | | | The two files are almost identical already basically just differ in the identifier names. By changing the identifiers to be the same, we are able to merge the two as a preparation to building a combined kernel.

|/ | | | | | | | | | | | | | | | | | Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

Nothing in the helper functions is ARM specific, so I hope that other implementations can consolidate some of their code by making use of these helpers. This has been sitting in linux-next most of the merge cycle, and has been tested by several OMAP folk. I've tested it on sa11x0 platforms, and given it my best shot on my broken platforms which have the amba-pl08x controller. The last point is the addition to feature-removal-schedule.txt, which will have a merge conflict. Between myself and TI, we're planning to remove the old TI DMA implementation next year."

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The register and irq definitions in mach/*.h for spear3xx and spear6xx are now mostly obsolete, after the platforms have been converted to device tree based probing and the data is now part of the device tree files. The misc_regs.h contents are moved into clock.c because that is the only user, aside from the DMA_CHN_CFG that should eventually get handled differently. Some of the contents of mach/spear.h still remain, because they are used to set up the static map table, timer, uart and auxdata tables, but almost everything got removed. We might remove everything but the map table as the DT conversion completes, but that is not a priority. I've also made sure to make both copies of spear.h more or less identical so we can eventually combine them. The spear3?0.h files were only used by the spear3?0.c files, so I merged the contents in there and removed the bits that were unused. This is something that should still be looked at.

* ARM: SPEAr600: Add device-tree support to SPEAr600 boardsStefan Roese2012-03-161-96/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a generic target for SPEAr600 board that can be configured via the device-tree. Currently the following devices are supported via the devicetree: - VIC interrupts - PL011 UART - PL061 GPIO - Synopsys DW I2C - Synopsys DW ethernet Other peripheral devices (e.g. SMI flash, FSMC NAND flash etc) will follow in later patches. Only the spear600-evb is currently supported. Other SPEAr600 based boards will follow later. Since the current mainline SPEAr600 code only supports the SPEAr600 evaluation board, with nearly zero peripheral devices (only UART and GPIO), it makes sense to switch over to DT based configuration completely now. So this patch also removes all non-DT stuff, mainly platform device data. The files spear600.c and spear600_evb.c are removed completely.
