2007-11-23sh: fix R2D-1 CF supportMagnus Damm1-0/+2
This patch fixes CF support for R2D-1 boards. Both R2D-1 and R2D-PLUS are equipped with CF IRQs, but the R2D-1 FPGA version seem to deliver IRQ spikes with certain CF cards during libata probing. This patch enables polling for R2D-1 as a workaround for this broken FGPA logic. R2D-1 CF support was recently introduced by commit: 43f4b8c7578b928892b6f01d374346ae14e5eb70.

2007-11-02sh: Fix up r7780rp highlander CF access size.Paul Mundt1-0/+31
R7780RP can't do byte-sized accesses to CF, so needs to do word sized access with low-byte masking. This same problem exists on older versions of the R2D, with the same workaround having been implemented in 43f4b8c7578b928892b6f01d374346ae14e5eb70 there. Follow that change for the highlander boards. This does not impact R7780MP or SH7785 based Highlander modules. If you're unfortunate enough to be stuck with an R7780RP, this patch is for you!

2007-10-30sh: add support for ax88796 and 93cx6 to highlander boardsMagnus Damm1-0/+40
This patch adds support for the ax88796 driver on highlander boards. Implemented using the 93cx6 EEPROM support introduced by commit-id 89e536a190f90d038bae7905a0c582cb7089b739. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-10-10sh: allow building for both r2d boards in same binary.Magnus Damm1-8/+1
This patch enables building for both R2D-PLUS and R2D-1 boards. All code is already in place except for the Kconfig limitation. This is useful if you want to run the same binary on both R2D-PLUS and R2D-1 boards. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-10-10sh: fix r2d board detectionMagnus Damm1-2/+5

2007-09-21sh: intc - rework higlander irq code for r7780mp and r7785rpMagnus Damm5-19/+152
This patch reworks the highlander irq code for r7780mp and r7785rp. The same strategy as for the new R2D code is used here - the board specific interrupts are now starting from HL_FPGA_IRQ_BASE. The code for r7780rp is not touched due to lack of hardware. Tested with CF, AX88796 on r7780mp and r7785rp. The touch switch interrupt has also been tested on r7780mp.

2007-09-21sh: minor fixesMagnus Damm1-1/+0
This patch contains the following fixes: - Adds sh7785 support to CONFIG_EARLY_SCIF_CONSOLE_PORT. - Removes duplicate include from rts7751r2d irq code. - Removes CONFIG_CPU_HAS_INTC from sh7720 Kconfig entry.

2007-09-21sh: Fix up heartbeat build and resource size.Paul Mundt3-4/+4
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>
2007-09-21sh: heartbeat driver update.Paul Mundt1-4/+12
Add some flags for the heartbeat driver, and kill off some duplication in the bit positions for the boards that don't have special cases. This also allows for variable access widths and inversion. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21sh: intc - mark data structures as __initdataMagnus Damm1-6/+4
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.

2007-09-21sh: replace sh specific CONFIG_VOYAGERGX with CONFIG_MFD_SM501Magnus Damm2-17/+24
This patch replaces all instances of CONFIG_VOYAGERGX with CONFIG_MFD_SM501. While at it we make sure the r2d code compiles both with and without SM501. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21sh: intc - convert board specific r2d codeMagnus Damm3-58/+147
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.

2007-09-21sh: x3proto: ILSEL IRQ support.Paul Mundt2-1/+152
This adds functionality for the on-board ILSEL IRQs that chain IRL mode events. Many on-board devices (ethernet, usb, etc.) rely on ILSEL IRQs directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21sh: Initial support for SH-X3 prototype board.Paul Mundt2-0/+55
This adds initial support for the SH-X3 prototype board. Only simple logic for the IRQ controller and the heartbeat driver for now. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21sh: intc - convert voyagergx codeMagnus Damm2-7/+4
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>
2007-08-03sh: fix cf support on r2d boardsMagnus Damm1-1/+8

2007-06-08sh: Kill off machvec aliases.Paul Mundt6-12/+6
We now throw all of the machvecs in to .machvec.init and either select one on the command line, or copy out the first (and usually only) one to sh_mv. The rest are freed as usual. This gets rid of all of the silly sh_mv aliasing and makes the selection explicit rather than link-order dependent. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Rework CPU/board dependencies.Paul Mundt1-3/+3
This was a big mess, rework the logic a bit so that we constrain to a particular subtype and figure out the board support based on that. This makes building subtype specific kernels supporting multiple boards possible again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-05-07sh: Add SH7785 Highlander board support (R7785RP).Paul Mundt6-68/+105
This adds preliminary support for the SH7785-based Highlander board. Some of the Highlander support code is reordered so that most of it can be reused directly. This also plugs in missing SH7785 checks in the places that need it, as this is the first board to support the CPU. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-03-05sh: Kill off I/O cruft for R7780RP.Paul Mundt3-254/+1

Tidy up the R7780RP I/O mapping routines and switch the pata_platform resources to IORESOURCE_MEM types, killing off the useless port->addr conversion. This fixes up R7780RP to boot after the recent devres conversion. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: heartbeat consolidation for banked LEDs.Paul Mundt6-96/+37
This consolidates the various board heartbeat LED implementations, used for strobing the load average across a LED bank. Those boards not implementing a full bank can hook in via the LED class. We leave the compat hook in the machvec for now until those non-banked boards are able to migrate to the drivers/leds. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

The iVDR clock enable bit happens to actually reside in a rather different place than what is documented, so fix it up accordingly. This fixes up SATA boot for some of the R7780RP boards that didn't default-enable the clock in the loader. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: platform_pata support for R7780RPPaul Mundt1-0/+29

2006-12-06sh: Drop CPU subtype IRQ headers.Paul Mundt1-0/+1
This drops the various IRQ headers that were floating around and primarily providing hardcoded IRQ definitions for the various CPU subtypes. This quickly got to be an unmaintainable mess, made even more evident by the subtle breakage introduced by the SH-2 and SH-2A changes. Now that subtypes are able to register IRQ maps directly, just rip all of the headers out. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-10-31sh: Fix IPR-IRQ's for IRQ-chip change breakage.Jamie Lenehan2-63/+54
The conversion from IPR-IRQ to IRQ-chip resulted in the ipr data being allocated in a local variable in make_ipr_irq - breaking anything using IPR interrupts. This changes all of the callers of make_ipr_irq to allocate a static structure containing the IPR data which is then passed to make_ipr_irq. This removes the need for make_ipr_irq to allocate any additional space for the IPR information. Signed-off-by: Jamie Lenehan <lenehan@twibble.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-10-19sh: Updates for irq-flow-type naming changes.Paul Mundt1-3/+3
