* [ARM] pxa: fix issue of muxed GPIO irq_chip functions touching non-muxed GPIOsEric Miao2009-04-271-4/+19
| | | | | | | | | | pxa_gpio_irq_type() and pxa_unmask_muxed_gpio() will touch non-muxed GPIOs (0 and 1 on PXA2xx/PXA3xx) bits in GRERx and GFERx, which is incorrect. Actually, only those bits should get updated if the corresponding bits are set in c->irq_mask as well. Fix this by updating only those relevant bits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Symbols like SOFT_RESET are way too generic to be exported at large. To avoid this, let's move the mbus bridge register defines into a separate file and include it where needed. This affects mach-kirkwood, mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all share code in plat-orion which relies on those defines. Some other defines have been moved to narrower scopes, or simply deleted when they had no user. This fixes compilation problem with mpt2sas on the above listed platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Firstly, this patch makes the palm27x asoc driver a little more sane. Also, since all affected devices use GPIO95 as AC97_nRESET, this patch sets that properly. Affected are PalmT5, TX and LifeDrive.

| | * [ARM] pxa/mioa701: use GPIO95 as AC97 reset lineRobert Jarzmik2009-04-151-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MioA701 board's GPIO95 is the AC97 line. The other GPIO113 is not connected to the sound chip, but to the GSM chip as a wakeup line. It happens that when the pxa2xx_ac97 driver reconfigures the gpio as an "out gpio" for AC97 reset (bug workaround), it hangs the GSM chip. As AC97 platform data now enables to specify the AC97 reset line, use it. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Eric Miao <eric.miao@marvell.com>
| | * [ARM] pxa: merge AC97 platform data structuresMark Brown2009-04-151-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there are two possible platform datas for the PXA AC97 driver: one supported by the generic AC97 driver only which provides callbacks to allow board-specific configuration at stream startup and teardown, and another for pxa2xx-ac97-lib which allows configuration of the reset GPIO for PXA2xx CPUs. Obviously this won't actually work when using the generic AC97 driver since the drivers will attempt to parse the platform data in both formats. Fix this by merging the two structures.

These syscalls simply take five long-sized parameters, so they should have no calling-convention/ABI issues in the kernel. Tested on armv5tel eabi using a preadv/pwritev test program posted on linuxppc-dev earlier this month. It would be nice to get this into the kernel before 2.6.30 final, so that glibc's kernel version feature test for these syscalls doesn't have to special-case ARM.

Otherwise the address and size cell counts are wrong and we don't calculate the final physical device resource values correctly at all. Commit 5280267c1dddb8d413595b87dc406624bb497946 ("sparc: Fix handling of LANCE and ESP parent nodes in of_device.c") was meant to fix this problem, but that only influences the inner loop of build_device_resources(). We need this logic to also kick in at the beginning of build_device_resources() as well, when we make the first attempt to determine the device's immediate parent bus type for 'reg' property element extraction.

This was safe, because the SATA driver re-enabled it. But with commit a5bfc471 ("ahci: drop intx manipulation on msi enable"), the driver no longer does this, and so SATA support on the 8610 HPCD is broken. The original quirk function disabled INTx because it caused some other interrupt problem during early development on this board, but no one remembers any more what that problem was, and it doesn't seem to occur any more.

* | | | | | FRV: Fix the section attribute on UP DECLARE_PER_CPU()David Howells2009-04-216-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In non-SMP mode, the variable section attribute specified by DECLARE_PER_CPU() does not agree with that specified by DEFINE_PER_CPU(). This means that architectures that have a small data section references relative to a base register may throw up linkage errors due to too great a displacement between where the base register points and the per-CPU variable. On FRV, the .h declaration says that the variable is in the .sdata section, but the .c definition says it's actually in the .data section. The linker throws up the following errors: kernel/built-in.o: In function `release_task': kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o To fix this, DECLARE_PER_CPU() should simply apply the same section attribute as does DEFINE_PER_CPU(). However, this is made slightly more complex by virtue of the fact that there are several variants on DEFINE, so these need to be matched by variants on DECLARE.

This is required because the CPU's window onto the PCI bus address space is considerably smaller than the CPU's full address space and non-PCI devices lie outside of the PCI window that we might want to access. Without this patch, the PCI root bus uses the platform-level bus resources, and these are then confined to the PCI window, thus making platform_device_add() reject devices outside of this window.
