* sh: intc - primary priority masking fixesMagnus Damm2007-09-20
| | | | | | | | | | | | | | | | | | | | This patch contains various intc fixes for problems reported by Markus Brunner on the linuxsh-dev mailing list: http://marc.info/?l=linuxsh-dev&m=118701948224991&w=1 Apart from added comments, the fixes are: - add intc_set_priority() function prototype to hw_irq.h - fix off-by-one error in intc_set_priority() - make sure _INTC_WIDTH() is set for primary priority masking Big thanks to Markus for finding these problems. Version two fixes a compile error and an inverted primary check.

* sh: intc - mark data structures as __initdataMagnus Damm2007-09-20
| | | | | | | | | | | With the intc core improved it is now possible to put the intc data structures in the initdata section. Version two of this patch puts the __initdata inside DECLARE_INTC_DESC() and removes the __initdata included in the board specific r2d code.

* sh: intc - convert board specific r2d codeMagnus Damm2007-09-20
| | | | | | | | | | | | | | | | | | | | | 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 - rework core codeMagnus Damm2007-09-20
| | | | | | | | | | | | | | | | | This patch reworks the intc core, implementing the following features: - Support dual priority registers - one set and one clear register - All 8/16/32 bit register combinations are now supported - Both single mask and single enable bitmap register are supported - Add code to set interrupt priority - Speedup sense and priority configuration code - Allocate data using bootmem, allows intc data structures to be __initdata - Save memory - allocated memory footprint is smaller than intc structures Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: intc - convert voyagergx codeMagnus Damm2007-09-20
| | | | | | | | | | | | | | | | | | | | 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 Damm2007-09-20
| | | | | | | | | | | | 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 shminMagnus Damm2007-09-20

* sh: intc - remove redundant irq code for sh03, snapgear and titanMagnus Damm2007-09-20
| | | | | | | | | | | | | | 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 Mundt2007-09-20
| | | | | | | | | | | | | | 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. The patch also adds the SIM block to the serial port platform data. Version two of this patch fixes MMCIF problems reported by Manuel Lauss.

* sh: intc - add support for SH7706, SH7707, SH7708, SH7709Magnus Damm2007-09-20
| | | | | | | | | | | | | | | | | | | 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.

* | signalfd simplificationDavide Libenzi2007-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies signalfd code, by avoiding it to remain attached to the sighand during its lifetime. In this way, the signalfd remain attached to the sighand only during poll(2) (and select and epoll) and read(2). This also allows to remove all the custom "tsk == current" checks in kernel/signal.c, since dequeue_signal() will only be called by "current". I think this is also what Ben was suggesting time ago. The external effect of this, is that a thread can extract only its own private signals and the group ones. I think this is an acceptable behaviour, in that those are the signals the thread would be able to fetch w/out signalfd.
