2013-02-20ARM: prima2: remove duplicate v7_invalidate_l1Arnd Bergmann1-40/+0
Patch c08e20d "arm: Add v7_invalidate_l1 to cache-v7.S" added a generic version of this function and removed all platform specific versions, while 4898de3 "ARM: PRIMA2: add new SiRFmarco SMP SoC infrastructures" added another one, leading to a link error. I verified that the two are identical, so we can just remove the one in mach-prima2. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2013-02-14ARM: prima2: fix __init section for cpu hotplugArnd Bergmann2-2/+3
The code in arch/arm/mach-prima2/headsmp.S is used for both boot time initialization and for cpu hotplug, so it must not be discarded after the initial boot is complete. This replaces the __INIT annotation with __CPUINIT, and marks the sirfsoc_cpu_die as __ref to annotate that it correctly uses the sections. Without this patch, building prima2_defconfig results in: WARNING: arch/arm/mach-prima2/built-in.o(.cpuinit.text+0x130): Section mismatch in reference from the function sirfsoc_boot_secondary() to the function .init.text:sirfsoc_secondary_startup() The function __cpuinit sirfsoc_boot_secondary() references a function __init sirfsoc_secondary_startup(). If sirfsoc_secondary_startup is only used by sirfsoc_boot_secondary then annotate sirfsoc_secondary_startup with a matching annotation.

2012-12-24ARM: delete struct sys_timerStephen Warren3-8/+4
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.

2012-10-15pinctrl: sirf: remove sirfsoc_gpio_set_pull functionArnd Bergmann1-13/+0
The prima2 platform advertises needing no mach/gpio.h header file, but its pinctrl driver now has a sirfsoc_gpio_set_pull function that uses constants defined in arch/arm/mach-prima2/include/mach/gpio.h, which fails to build. Fortunately, the sirfsoc_gpio_set_pull is not used anywhere in the kernel, so we can safely remove it. Any out of tree drivers using it will have to be converted to use proper pinctrl functions to do the same. Without this patch, building prima2_defconfig results in: drivers/pinctrl/pinctrl-sirf.c: In function 'sirfsoc_gpio_set_pull': drivers/pinctrl/pinctrl-sirf.c:1331:7: error: 'SIRFSOC_GPIO_PULL_NONE' undeclared (first use in this function) drivers/pinctrl/pinctrl-sirf.c:1331:7: note: each undeclared identifier is reported only once for each function it appears in drivers/pinctrl/pinctrl-sirf.c:1334:7: error: 'SIRFSOC_GPIO_PULL_UP' undeclared (first use in this function) drivers/pinctrl/pinctrl-sirf.c:1338:7: error: 'SIRFSOC_GPIO_PULL_DOWN' undeclared (first use in this function) Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Barry Song <Baohua.Song@csr.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-10-13ARM: config: sort select statements alphanumericallyRussell King1-1/+1
As suggested by Andrew Morton: This is a pet peeve of mine. 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.

Pull ARM soc multiplatform enablement from Olof Johansson: "This is a pretty significant branch. 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.

2012-08-02ARM: PRIMA2: delete redundant codes to restore LATCHED when timer resumesBarry Song1-3/+3
The only way to write LATCHED registers to write LATCH_BIT to LATCH register, that will latch COUNTER into LATCHED.e.g. writel_relaxed(SIRFSOC_TIMER_LATCH_BIT, sirfsoc_timer_base + SIRFSOC_TIMER_LATCH); Writing values to LATCHED registers directly is useless at all.

In SiRFprimaII, Each GPIO pin can be configured as input or output independently. If a GPIO is configured as input, it can also be enabled as an interrupt source (either edge or level triggered). These pins must be either MUXed as GPIO or other function pads.

2012-02-16irq_domain: Remove irq_domain_add_simple()Grant Likely1-1/+1
irq_domain_add_simple() was a stop-gap measure until complete irq_domain support was complete. This patch removes the irq_domain_add_simple() interface. This patch also drops the explicit irq_domain initialization performed by the mach-versatile code because the versatile interrupt controller already has irq_domain support built into it. This was a bug that was hanging around quietly for a while, but with the full irq_domain which actually verifies that irq_domain ranges are available it would cause the registration to fail and the system wouldn't boot. v4: Fixed number of irqs in mx5 gpio code v2: Updated to pass in host_data pointer on irq_domain allocation.

Remove the now empty arch_reset() from all the mach/system.h includes, and remove its callsite. Remove arm_machine_restart() as this function no longer does anything useful. For samsung platforms, remove the include of mach/system-reset.h and plat/system-reset.h from their respective mach/system.h headers as these just define their arch_reset functions. As a result, the s3c2410 and plat-samsung system-reset.h files are no longer referenced, so remove these files entirely.
