2011-10-05fix cache coherence issues with bounce buffersMian Yousaf Kaukab
[Rabin VINCENT] This is for I$-D$ coherence issues when bounce buffers are used for the MMC driver and code is executed from a file system on eMMC. IMO a better fix is to either change flush_kernel_dcache_page() to flush the D$ even on VIPT non-aliasing caches or to replace the flush_kernel_dcache_page() in lib/scatterlist.c with flush_dcache_page().

2011-10-05x86, AMD: Fix APIC timer erratum 400 affecting K8 Rev.A-E processorsBoris Ostrovsky
commit e20a2d205c05cef6b5783df339a7d54adeb50962 upstream. Older AMD K8 processors (Revisions A-E) are affected by erratum 400 (APIC timer interrupts don't occur in C states greater than C1). This, for example, means that X86_FEATURE_ARAT flag should not be set for these parts. This addresses regression introduced by commit b87cf80af3ba4b4c008b4face3c68d604e1715c6 ("x86, AMD: Set ARAT feature on AMD processors") where the system may become unresponsive until external interrupt (such as keyboard input) occurs. This results, for example, in time not being reported correctly, lack of progress on the system and other lockups.

2011-10-05ARM: Implement a timer based __delay() loopStephen Boyd
udelay() can be incorrect on SMP machines that scale their CPU frequencies independently of one another (as pointed out here http://article.gmane.org/gmane.linux.kernel/977567). The delay loop can either be too fast or too slow depending on which CPU the loops_per_jiffy counter is calibrated on and which CPU the delay loop is running on. udelay() can also be incorrect if the CPU frequency switches during the __delay() loop, causing the loop to either terminate too early, or too late. Forcing udelay() to run on one CPU is unreasonable and taking the penalty of a rather large loops_per_jiffy in udelay() when the CPU is actually running slower is bad for performance. Solve the problem by adding a timer based__delay() loop unaffected by CPU frequency scaling. Machines should set this loop as their __delay() implementation by calling set_timer_fn() during their timer initialization. The kernel is already prepared for a timer based approach (evident by the read_current_timer() function). If an arch implements read_current_timer(), calibrate_delay() will use calibrate_delay_direct() to calculate loops_per_jiffy (in which case loops_per_jiffy should really be renamed to timer_ticks_per_jiffy). Since the loops_per_jiffy will be based on timer ticks, __delay() should be implemented as a loop around read_current_timer(). Doing this makes the expensive loops_per_jiffy calculation go away (saving ~150ms on boot time on my machine) and fixes udelay() by making it safe in the face of independently scaling CPUs. The only prerequisite is that read_current_timer() is monotonically increasing across calls (and doesn't overflow within ~2000us). There is a downside to this approach though. BogoMIPS is no longer "accurate" in that it reflects the BogoMIPS of the timer and not the CPU. On most SoC's the timer isn't running anywhere near as fast as the CPU so BogoMIPS will be ridiculously low (my timer runs at 4.8 MHz and thus my BogoMIPS is 9.6 compared to my CPU's 800). This shouldn't be too much of a concern though since BogoMIPS are bogus anyway (hence the name). This loop is pretty much a copy of AVR's version.

2011-10-05ARM: Allow machines to override __delay()Stephen Boyd
Some machines want to implement their own __delay() routine based on fixed rate timers. Expose functionality to set the __delay() routine at runtime. This should allow two machines with different __delay() routines to happily co-exist within the same kernel with minimal overhead. Russell expressed concern that using a timer based __delay() would cause problems when an iomapped device isn't mapped in prior to a delay call being made (see http://article.gmane.org/gmane.linux.ports.arm.kernel/78543 for more info). We can sidestep that issue with this approach since the __delay() routine _should_ only be pointed to a timer based delay once the timer has been properly mapped. Up until that point __delay() and udelay() will use delay_loop() which is always safe to call. This patch is inspired by x86's delay.c Reviewed-by: Saravana Kannan <skannan@codeaurora.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Change-Id: I269f101b40ba50c2b635dc92d50f6e82bb934b32 Reviewed-on: http://gerrit.lud.stericsson.com/gerrit/13563 Tested-by: Mattias WALLIN <mattias.wallin@stericsson.com> Reviewed-by: Jonas ABERG <jonas.aberg@stericsson.com>
2011-10-05ARM: Translate delay.S into (mostly) CPhilippe Langlais
We want to allow machines to override the __delay() implementation at runtime so they can use a timer based __delay() routine. It's easier to do this using C, so let's write udelay and friends in C. We lose the #if 0 code, which according to Russell is used "to make the delay loop more stable and predictable on older CPUs" (see http://article.gmane.org/gmane.linux.kernel/888867 for more info). We shouldn't be too worried though, since we'll soon add functionality allowing a machine to set the __delay() loop themselves, thus allowing machines to resurrect the commented out code should they need it. Nico expressed concern that fixed lpj cmdlines will break due to compiler optimizations. That doesn't seem to be the case since before and after this patch I get the same lpj value when running my CPU at 19.2 MHz. That should be sufficiently slow enough to cover any machine running Linux.

This patch adds functions to flush and clean the entire data cache. Since the existing flush/clean range functions take more time to flush/clean the entire data cache, they cannot be used. Whenever the range of data to be flushed/cleaned from the data cache is more than some threshold value, it is better to do the entire data flush/clean, this will reduce the time taken and effectively increases the performance of the system.

2011-10-05backlight/leds: add low threshold to pwm backlight/ledPhilippe Langlais
The intensity of the backlight/led can be varied from a range of max_brightness to zero. Though most, if not all the pwm based backlight/led devices start flickering at lower brightness value. And also for each device there exists a brightness value below which the backlight appears to be turned off though the value is not equal to zero. If the range of brightness for a device is from zero to max_brightness. A graph is plotted for brightness Vs intensity fo the pwm based backlight/led device has to be a linear graph. intensity | / | / | / |/ --------- 0 max_brightness But pratically on measuring the above we note that the intensity of backlight/led goes to zero(OFF) when the value in not zero almost nearing to zero(some x%). so the graph looks like intensity | / | / | / | | ------------ 0 x max_brightness In order to overcome this drawback knowing this x% i.e nothing but the low threshold beyond which the backlight/led is off and will have no effect, the brightness value is being offset by the low threshold value(retaining the linearity of the graph). Now the graph becomes intensity | / | / | / | / ------------- 0 max_brightness With this for each and every digit increment in the brightness from zero there is a change in the intensity of backlight/led. Devices having this behaviour can set the low threshold brightness(lth_brightness) and pass the same as platform data else can have it as zero.

2011-10-05PM: Add support for device power domainsRafael J. Wysocki
The platform bus type is often used to handle Systems-on-a-Chip (SoC) where all devices are represented by objects of type struct platform_device. In those cases the same "platform" device driver may be used with multiple different system configurations, but the actions needed to put the devices it handles into a low-power state and back into the full-power state may depend on the design of the given SoC. The driver, however, cannot possibly include all the information necessary for the power management of its device on all the systems it is used with. Moreover, the device hierarchy in its current form also is not suitable for representing this kind of information. The patch below attempts to address this problem by introducing objects of type struct dev_power_domain that can be used for representing power domains within a SoC. Every struct dev_power_domain object provides a sets of device power management callbacks that can be used to perform what's needed for device power management in addition to the operations carried out by the device's driver and subsystem. Namely, if a struct dev_power_domain object is pointed to by the pwr_domain field in a struct device, the callbacks provided by its ops member will be executed in addition to the corresponding callbacks provided by the device's subsystem and driver during all power transitions.

2011-10-05i2c-nomadik: Change the TX and RX ThresholdPhilippe Langlais
1) Increase RX FIFO threshold so that there is a reduction in the number of interrupts handled to complete a transaction. 2) Fill TX FIFO in the write function.

2011-10-05i2c-nomadik: Add code to retry on timeout failure and set i2c clock to 400KHzPhilippe Langlais
It is seen that i2c-nomadik controller randomly stops generating the interrupts leading to a i2c timeout. As a workaround to this problem add retries, to the on going transfer on failure. Since this behaviour does not get changed with a wait for longer duration, the timeout can be reduced to a lower value, leading to a quicker retry attempt.
