| | | | | | | | | | | | | | | | | | | | Use DT_MACHINE_START() on the r8a7740 based armadillo 800 eva board. Also include a tiny DTS file to describe the board and update the Kconfig dependencies to select CONFIG_USE_OF. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J.

* ARM / mach-shmobile: Use preset_lpj with calibrate_delay()Magnus Damm2012-05-121-1/+2
| | | | | | | | | | | | | | | | | | | | Update the mach-shmobile shared delay calibration code for late timers. All existing in-tree non-DT socs are however using early timers today and they are unaffected by this change. The patch modifies shmobile_setup_delay() from using lpj_fine to preset_lpj. This change allows us to preset the worst case loops-per-jiffy value to all CPU cores on the system. The old code which made use of lpj_fine did not affect the secondary CPU cores which made it impossible to boot on SMP without early timers. Needed for SMP SoCs using late timers like EMEV2 or any other mach-shmobile SMP SoC that makes use of late timers via DT. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is the sh7372 INTC demux rework V2. Updates the sh7372 INTCS demuxer to not hook into the INTCA interrupt controller. The mask register for the chained INTCS interrupt source happens to be located in the INTCS register range instead of the INTCA as expected. To allow each INTCA and INTCS interrupt controller to work in their own IRQ range this patch moves the INTCS vector away. Needed for future IRQ domain support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Damm2012-04-111-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This patch removed shmobile_twd_init() which is no longer needed Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J.
