2010-10-28rapidio: fix IDLE2 bits corruptionAlexandre Bounine1-7/+2
RapidIO spec v.2.1 adds Idle Sequence 2 into LP-Serial Physical Layer. The fix ensures that corresponding bits are not corrupted during error handling.

2010-10-28rapidio: add handling of redundant routesAlexandre Bounine3-51/+54
Detects RIO link to the already enumerated device and properly sets links between device objects. Changes to the enumeration/discovery logic: 1. Use Master Enable bit to signal end of the enumeration - agents may start their discovery process as soon as they see this bit set (Component Tag register was used before for this purpose). 2. Enumerator sets Component Tag (!= 0) immediately during device setup. This allows to identify the device if the redundant route exists in a RIO system.

2010-10-28synclink_gt: fix per device lockingPaul Fulghum1-13/+15
Fix a long standing bug with per device locking. Each device has an associated spinlock for synchronizing access to hardware and state information with the ISR. A single hardware card has one or more devices. Bug: Non ISR code correctly acquires and releases the per device lock. ISR incorrectly always acquires and releases the lock of the first device on the card. The decoupled and list based nature of the ISR and deferred processing interaction allowed this to work in normal operation. Exceptional events like an application forcing hardware shutdown, reset, or reconfiguration while active can trigger the bug. Fixed ISR to acquire and release the per device lock. One exception is manipulation of the GPIO card resource which is global and effectively owned by the first device of the card. Non-ISR access to GPIO resource is changed to use lock of first device on card.

2010-10-28fbmem: fix fb_read, fb_write unaligned accessesJames Hogan1-32/+14
fb_{read,write} access the framebuffer using lots of fb_{read,write}l's but don't check that the file position is aligned which can cause problems on some architectures which do not support unaligned accesses. Since the operations are essentially memcpy_{from,to}io, new fb_memcpy_{from,to}fb macros have been defined and these are used instead. For Sparc, fb_{read,write} macros use sbus_{read,write}, so this defines new sbus_memcpy_{from,to}io functions the same as memcpy_{from,to}io but using sbus_{read,write}b instead of {read,write}b.

I tested savagefb on 3 different Savage 4 cards: Diamond Stealth III S520 Number Nine SR9 Datapath Horizon 2S (two savage chips on a PCI card) it worked except the DDC which did not work on any of them. Looking at the BIOS code, it does not use MMIO register 0xff20 but CRT register 0xa0 or 0xb1 - depending on the chip revision and something in register 0xa6. With this patch, DDC works fine on all 3 cards (even on the second head of Horizon 2S - although it does not display anything as it's misconfigured because of missing BIOS).

Change RTC initialization method in probe(). The 'rtc_valid_tm(tm)' can check whether RTC BCD is valid or not. And change the method of checking because the previous method cannot validate RTC BCD registers properly.

The alarm_irq_enable function should be implemented to support RTC alarm. And fix tabs instead of white space around the proc field.

Current s3c_rtc_getalarm() sets missing field of alarm time with 0xff. But this value should be -1 according to drivers/rtc/interface.c.

2010-10-28rtc: omap: let device wakeup capability be configured from chip init logicSekhar Nori1-5/+7
The rtc-omap driver currently hardcodes the RTC wakeup capability to be "not capable". While this seems to be true for existing OMAP1 boards which are not wired for this, the DA850/OMAP-L138 SoC, the RTC can always be wake up source from its "deep sleep" mode. This patch lets the wakeup capability be set from platform data and does not override the setting from the driver. For DA850/OMAP-L138, this is done from arch/arm/mach-davinci/devices-da8xx.c:da8xx_register_rtc() Note that this patch does not change the behavior on any existing OMAP1 board since the platform device registration sets the wakeup capability to 0 by default.
