2017-07-27ARM: sirf: mark sirfsoc_init_late as __maybe_unusedArnd Bergmann1-1/+1
sirfsoc_init_late is called by each of the three individual SoC definitions, but in a randconfig build, we can encounter a situation where they are all disabled: arch/arm/mach-prima2/common.c:18:123: warning: 'sirfsoc_init_late' defined but not used [-Wunused-function] While that is not a useful configuration, the warning also doesn't help, so this patch marks the function as __maybe_unused to let the compiler know it is there intentionally. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2015-02-19ARM: make arrays containing machine compatible strings constUwe Kleine-König1-3/+3
The definition static const char *axxia_dt_match[] __initconst = { ... defines a changable array of constant strings. That is you must not do: *axxia_dt_match[0] = 'k'; but axxia_dt_match[0] = "different string"; is fine. So the annotation __initconst is wrong and yields a compiler error when other really const variables are added with __initconst. As the struct machine_desc member dt_compat is declared as const char *const *dt_compat; making the arrays const is the better alternative over changing all annotations to __initdata.

2015-01-20ARM: sirf: move to debug_ll_io_init and drop map_ioBarry Song1-7/+0
This patch moves to debug_ll_io_init(), then finally drops CSR map_io() machine callbacks. Signed-off-by: Barry Song <Baohua.Song@csr.com> Acked-by: Arnd Bergmann <arnd@arndb.de>
2015-01-20ARM: sirf: move platsmp to support Atlas7 SoCZhiwu Song1-1/+0
This patch breaks Marco SMP support, but Marco project has been dropped. So it corrects cpu1 jump/flag address for Atlas7 and removes scu related logic as scu doesn't expose in cortex-a7.

2014-05-30ARM: l2c: prima2: convert to generic l2c OF initialisationRussell King1-0/+6
Remove the explicit call to l2x0_of_init(), converting to the generic infrastructure instead. Along with this change, we can delete l2x0.c from prima2. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2014-03-17ARM: prima2: build reset code standaloneArnd Bergmann1-3/+0
The prima2 platform code currently depends on the rstc implementation and that in turn depends on the reset controller framework. This removes the platform dependency by letting the driver access arm_pm_restart directly to turn the driver into a standalone entity, and also removes the dependency on the reset controller framework by using "if (IS_ENABLED(CONFIG_RESET_CONTROLLER))". This will cause all code that is used for the reset controller to be dropped by the compiler if the framework is disabled. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2013-09-29ARM: prima2: remove custom .init_time hookSebastian Hesselbarth1-11/+0

2013-09-29clk: prima2: declare OF clock providerSebastian Hesselbarth1-2/+2
Common clock framework allows to register clock providers to get called on of_clk_init() by using CLK_OF_DECLARE.

Most notable here is the removal of support for ATAGS based OMAP4 systems. Since all OMAP4 machines are fully functional with DT based booting in 3.10, we can remove a lot of code here. Also noteworthy is Maxime Ripard's cleanup of the machine descriptors, which means we need no machine descriptors in a lot more cases and can boot additional machines by just having the respective device drivers enabled." * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (76 commits) ARM: picoxcell: remove .nr_irqs reference ARM: s5p64x0: avoid build warning for uncompress.h ARM: SAMSUNG: Remove unused plat/regs-watchdog.h header ARM: SAMSUNG: Remove legacy watchdog reset code ARM: SAMSUNG: Let platforms use the new watchdog reset driver ARM: SAMSUNG: Add watchdog reset driver ARM: SAMSUNG: Use local definitions of watchdog registers watchdog: s3c2410_wdt: Use local register definitions ARM: S5P64X0: Use common uncompress.h part for plat-samsung ARM: SAMSUNG: Consolidate uncompress subroutine ARM: at91: drop rm9200dk board support ARM: dts: msm: Fix merge resolution ARM: OMAP1: Remove dma.h ARM: OMAP1: Remove legacy irda.h and irda setup from board files ARM: OMAP1: Remove duplicated DMA channel definitions ARM: OMAP1: Remove McBSP DMA channel definitions ARM: OMAP2+: Remove dma.h ARM: OMAP2+: hwmod: Remove remaining DMA channel definitions ARM: OMAP2+: Remove duplicated DMA channel definitions ARM: OMAP2+: Remove AES crypto device DMA channel definitions ...
2013-06-03arm: prima2: use of_platform_populate instead of of_platform_bus_probeBarry Song1-13/+0
use of_platform_populate to populate platform devices, it is suitable for creating devices which are children of the root node, then makes things like pcm work. this patch removes sirfsoc_mach_init() function and lets arm core do of_platform_populate: static int __init customize_machine(void) { /* * customizes platform devices, or adds new ones * On DT based machines, we fall back to populating the * machine from the device tree, if no callback is provided, * otherwise we would always need an init_machine callback. */ if (machine_desc->init_machine) machine_desc->init_machine(); else of_platform_populate(NULL, of_default_bus_match_table, NULL, NULL); return 0; } Signed-off-by: Barry Song <Baohua.Song@csr.com> Signed-off-by: Rongjun Ying <Rongjun.Ying@csr.com>

2013-01-22ARM: PRIMA2: add new SiRFmarco SMP SoC infrastructuresBarry Song1-1/+39
this patch adds tick timer, smp entries and generic DT machine for SiRFmarco dual-core SMP chips. with the added marco, we change the defconfig, using the same defconfig, we get a zImage which can work on both prima2 and marco.

2013-01-22ARM: PRIMA2: irq: make prima2 irq can work even we enable GIC for MarcoBarry Song1-0/+3
in Marco, we will use GIC. this patch prepares the handle_irq for prima2 to avoid the compiling errors since we want only one defconfig and zImage for both prima2 and marco that means we will need handle_irq for both. Signed-off-by: Baohua Song <Baohua.Song@csr.com>
2013-01-22ARM: PRIMA2: mv timer to timer-prima2 as we will add timer-marcoBarry Song1-1/+1
Marco timer has different timer IP with prima2, so rename the current timer to timer-prima2 so that we can add timer-marco. at the same time, if we don't find prima2 timer node in dt, don't panic the system as we will make prima2 and marco use same kernel image.

2012-12-24ARM: delete struct sys_timerStephen Warren1-1/+1
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.
