| * ARM: shmobile: Make rmobile_init_pm_domain() staticRafael J. Wysocki2012-09-03
| | | | | | | | | | | | | | | | | | | | Since rmobile_init_pm_domain() is not called anywhere outside of arch/arm/mach-shmobile/pm-rmobile.c any more, it can be made static and its header may be removed from pm-rmobile.h. Modify the code accordingly. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Magnus Damm <damm@opensource.se>

| | | | | | | | | | | | | | | | | | | | | | | | | | If the r8a7779's PM domains are given names, this SoC and its boards will be able to use rmobile_add_device_to_domain() for adding devices to those domains and r8a7779_add_device_to_domain(), which is not used anywhere at the moment anyway, may be dopped.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update mach-shmobile to use 0x3400 as INTCS_VECT_BASE. Since the ARM architecture a little while back added support for 10 bit irqs we can now undo the previously merged commit 9b7c23adb350a108737a993c9c781463c1439dc6 and use 0x3400 as INTCS vector base. This change is necessary to avoid overlapping of interrupt ranges so separate IRQ domains can be used for different INTC instances. Without this fix the vectors used by various INTC instances are overlapping on for instance sh7372 which works at the moment but breaks upcoming IRQ domain support.

| * | ARM: mach-shmobile: Introduce INTC_IRQ_PINS_16HMagnus Damm2012-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add INTC_IRQ_PINS_16H to allow broken out support of the the high 16 external interrupt pins. On SoCs with 32 external interrupt pins the interrupt vectors for the low 16 and the high 16 interrupt pins are sparesly populated. The low 16 are at 0x0200 and high 16 are at 0x3200 which with current macros results in a separation of 384 linux interrupts. This sparse population makes it unsuitable with a single IRQ domain to cover the full IRQ range, so this macro breaks out the 32 pins into two separate 16 bit controllers to allow two independent INTC instances with two separate IRQ domains.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | Add the function shmobile_setup_delay() to let platforms configure their maximum loops per jiffy delay. With this jiffies calculation done the dependency on early timer is removed. In the future this allows us to assign timers using the regular driver model via the device tree.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix SMP TWD boot regression on sh73a0 based platforms caused by: 4200b16 ARM: shmobile: convert to twd_local_timer_register() interface After the merge of the above commit it has been impossible to boot sh73a0 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The kernel crashes at smp_init_cpus() timing which is before the console has been initialized, so to the user this looks like a kernel lock up without any particular error message. This patch fixes the regression on sh73a0 by moving the TWD registration code from smp_init_cpus() to sys_timer->init() time.
