* clocksource: nomadik-mtu: fix up clocksource/timerLinus Walleij2013-04-261-0/+1
| | | | | | | | | The Nomadik clocksource driver has had a bad define making it impossible to use it for sched_clock() for a while. Fix this and also enable it for the Nomadik. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net>
* ARM: nomadik: hide MACH_NOMADIK_8815NHK in KconfigArnd Bergmann2013-03-191-0/+2
| | | | | | | | | The nomadik multiplatform support made it possible to select MACH_NOMADIK_8815NHK without selecting ARCH_NOMADIK, which leads to build errors when we also select ARMv6/v7 targets. Adding the ifdef here restores the intended behavior. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
* ARM: nomadik: delete remnant include filesLinus Walleij2013-03-073-70/+0
| | | | | | | | This deletes the leftover <mach/timex.h> and <mach/uncompress.h> and Makefile.boot that have no role in a multiplatform environment. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: nomadik: convert to multiplatformLinus Walleij2013-03-071-3/+19
| | | | | | | | | | | This converts the Nomadik to run in multiplatform mode, including the defconfig change. After this the "uImage" target in the kernel tree will no longer work, but we do not care about this. Instead we generate the uImage from the zImage using mkimage or update the bootloader to accept bootz. Some minor updates to the defconfig are done as part of this.

| * ARM: nomadik: delete old board filesLinus Walleij2013-01-286-533/+4
| | | | | | | | | | | | | | | | The Device Tree support on Nomadik can do everything the old board files could do, so delete the old board files and make the nomadik select CONFIG_OF. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

| | | | | | | | | | | | | | | | | | This moves over the MMC/SD card support to the device tree probe path. The special GPIO to bias the card detect line is kept, but the pin property is moved to the device tree as part of the MMC/SD card node. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
| * ARM: nomadik: convert SMSC91x ethernet to device treeLinus Walleij2013-01-282-0/+36
| | | | | | | | | | | | | | | | | | | | This converts the SMSC91x ethernet controller to use device tree. The existing solution from the board file, to request the GPIO triggering the ethernet IRQ from the board file is kept for the time being, but the GPIO number assignment is moved over to the device tree.

| * ARM: nomadik: move GPIO and pinctrl to device treeLinus Walleij2013-01-281-4/+17

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the FSMC NAND driver and flash partitions to the Nomadik device tree. The only compatible string accepted by this driver is currently "st,spear600-fsmc-nand" which is inappropriate for this system, so this patch adds the compatible value "stericsson,fsmc-nand" as well.

| * ARM: nomadik: initial devicetree supportLinus Walleij2013-01-284-1/+87
| | | | | | | | | | | | | | | | | | | | | | Support basic device tree boot on the Nomadik. Implement the support in the cpu file with the intent of deleting the board files later. At this stage IRQ controllers, system timer, l2x0 cache, UARTs and thus console boot is fully functional. Patch out the code adding devices by initcalls for now so as not to disturb the boot.

| | | | | | | | | | | | | | | | | | | | The I2C pins were still set up using custom nmk_* calls, move these to use the pinctrl mapping table instead. There was also a remaining call to turn the Ethernet pin to GPIO, and this is now done implicitly by the GPIO-to-pinctrl range translation calls.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bump the IRQ numbers from offset at 1 (right above NO_IRQ) to 32. This is the painful way to learn that if you're using SPARSE_IRQ and avoid to define .nr_irqs in your machine, the first 16 IRQs will be pre-allocated, and the IRQdomain code (as the VIC core code before it) will then assume that all IRQ descriptors are pre-allocated, and 16 of them are - by somebody else. So mapping the IRQs will fail in irq_create_mapping(). Moving the offset upward rids us of this problem.

As this moves the last file being compiled to an object out of arch/arm/plat-nomadik, we have to "turn off the light" and delete the plat-nomadik directory, because it is not allowed to have an empty Makefile in a plat-* directory. This is probably also a desired side effect of depopulating the arch/arm directory of drivers. Luckily we have just deleted all the <plat/*> include files prior to this so by moving the last one we may delete the directory. After this all the Ux500 and Nomadik device drivers live outside of the arch/arm hierarchy.

Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines.

It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while.
