* sh: intc - irl mode update for sh7780 and sh7785Magnus Damm2007-09-213-4/+85
| | | | | | | | | | | | | | This patch contains the following fixes and improvements: - Fix address typo for INTMSK2 / INTMSKCLR2 registers on sh7780. - Adds IRQ_MODE_IRLnnnn_MASK using intc controller for IRL masking. - Good old IRQ_MODE_IRLnnnn should not register any intc controller. - plat_irq_setup_pins() now selects IRL or IRQ mode. - the holding function is now disabled using ICR0. By default all external pin interrupts are disabled. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* fb: pvr2fb: Shared IRQ for dreamcast pvr2.Adrian McMenamin2007-09-211-1/+1
| | | | | | | | | | | The maple bus driver (http://lkml.org/lkml/2007/9/4/165) uses hardware synchronisation between the maple bus and the VBLANK to poll the maple bus. This patch makes the interrupt shareable. By definition the interrupt is for both devices. Signed-off by: Adrian McMenamin <adrian@mcmen.demon.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: remove CONFIG_CPU_HAS_INTC_IRQMagnus Damm2007-09-213-25/+1
| | | | | | | | | All processor specific interrupt code is now converted to make use of the new intc code. The config option CONFIG_CPU_HAS_INTC_IRQ is because of that pointless. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix up heartbeat build and resource size.Paul Mundt2007-09-2111-15/+15
| | | | | | | | | We were abusing the resource size for the number of bits, this has been reworked using proper platform data, so this can be tidied up now. Boards in general only have a 1-byte wide resource, which the ioremap_nocache() case already handles. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: defconfigs for R2D-PLUS and for R2D-1Magnus Damm2007-09-212-329/+1310
| | | | | | | | | | | | | | This patch removes the old r2d config file named rts7751r2d_defconfig and adds separate config files for the two r2d board versions. The two new defconfigs are identical with the exception of board selection: - rts7751r2dplus_defconfig selects CONFIG_RTS7751R2D_PLUS=y - rts7751r2d1_defconfig selects CONFIG_RTS7751R2D_1=y Please remember to update both files with r2d changes in the future.

* sh: Overhaul spinlocks and rwlocks for SH-4A SMP.Paul Mundt2007-09-212-46/+146
| | | | | | | | | | This rips out some of the old spinlock and rwlock behaviour that the SH-2 parts were using and reworks them for LL/SC semantics on the SH-4A. This is primarily only useful for SH-X3 multi-cores, but can also be used for building CONFIG_SMP=y testing kernels on SH-4A UP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | With the intc core improved it is now possible to put the intc data structures in the initdata section.

* sh: intc - convert board specific r2d codeMagnus Damm2007-09-215-97/+181
| | | | | | | | | | | | | | | | | | | | | This patch converts the board specific interrupt code for r2d to make use of intc. While at it we improve the Kconfig to avoid confusion. - Two sets of interrupt tables exist - one for R2D-1 and one for R2D-PLUS. - R2D-1 and R2D-PLUS use the same irq constants. - R2D-1 has AX88796 support, R2D-PLUS does not hook up that IRQ. - R2D-PLUS has KEY support, R2D-1 does not hook up that IRQ. - The number and order of IRQ values are disconnected from register bits. - Interrupt sources now start from IRQ 100. - The machvec demux function converts from irlm IRQ 0-14 to IRQ 100++. Tested on R2D-1 and R2D-PLUS boards. Version 2 adds CONFIG_RTS7751R2D_1 and CONFIG_RTS7751R2D_PLUS together with intc structured as __initdata.

* sh: intc - convert voyagergx codeMagnus Damm2007-09-214-143/+95
| | | | | | | | | | | | | | | | | | | | This patch converts the sh-specific voyagergx interrupt code to make use of intc. A lot of "interesting" old cruft gets replaced with intc tables and some simple demux code. - All interrupt sources in the sm501 data sheet are now in the header. - The number and order of IRQ values are disconnected from register bits. - Interrupt sources now start from IRQ 200. - set_irq_chained_handler() is now used to hook up the demux function. In the future it would probably make sense to move the interrupt demuxer into into the mfd driver, but this is probably a nice step in the right direction until that happens. Tested on a R2D-1 board using the serial port hooked up to the sm501. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - add single bitmap register supportMagnus Damm2007-09-212-11/+63
| | | | | | | | | | | | This patch adds single bitmap register support to intc. The current code only handles 16 and 32 bit registers where a set bit means interrupt enabled, but this is easy to extend in the future. The INTC_IRQ() macro is also added to provide a way to hook in interrupt controllers for FPGAs in boards or companion chips.

* sh: intc - remove redundant irq code for sh03, snapgear and titanMagnus Damm2007-09-218-109/+19
| | | | | | | | | | | | | | This patch removes redundant board specific interrupt code for boards using sh775x processors and 4 IRQ lines in "Individual Interrupt Mode" aka IRLM. Three boards are affected: sh03, snapgear and titan. The right way to do this is to use cpu specific code provided by intc. A nice side effect is that sh03 now compiles, board not BROKEN any more.

* rtc: rtc-sh: Support 4-digit year on SH7705/SH7710/SH7712.Paul Mundt2007-09-214-21/+58
| | | | | | | | | | | | | | All SH-4 parts have a 4-digit year, while the SH-3 parts typically only use a 2-digit one. The SH7705, SH7710, and SH7712 SH-3 parts however opted to extend it to 4-digit and still look and act like an SH-3 RTC in all other ways. This adds a capability flag (RTC_CAP_4_DIGIT_YEAR) that these corner-case CPU subtypes can set in their platform data and cleans up some of the ifdef mess in the driver as a result.

New vectors are also added to match the information provided by the datasheet. Vectors for IRQ4-IRQ7 are enabled by default. Use plat_irq_setup_pins() if pins IRL0-3 should be used in IRLM mode.

* sh: intc - add support for SH7706, SH7707, SH7708, SH7709Magnus Damm2007-09-215-194/+220
| | | | | | | | | | | | | | | | | | | This patch unifies the cpu specific interrupt setup code for sh7706, sh7707, sh7708 and sh7709 and moves the code into a new file called setup-sh770x.c. It makes sense to share the setup code between these processors because most hardware blocks are identical from a software point of view. With this patch the sh770x processors now have a complete set of vectors that match with the information provided by the data sheets. This is a big improvement for sh7708. Vectors for IRQ4 and IRQ5 are enabled by default. Use plat_irq_setup_pins() if pins IRQ0-3 should be used in IRQ mode. This patch also unifies the platform device setup code which means that the rtc driver now has platform data for all sh770x processors.
