2011-05-28ALSA: fix hda AZX_DCAPS_NO_TCSEL quirk check in driver_capsLinus Torvalds1-1/+1
Commit 9477c58e3308 ("ALSA: hda - Reorganize controller quriks with bit flags") changed the driver type compares into various quirk bits. However, the check for AZX_DCAPS_NO_TCSEL got reverted: instead of clearing TCSEL for chipsets that have that standard capability, it cleared then when the NO_TCSEL bit was set. This can lead to noise and repeated sounds - a weird "echo" behavior. As the comment just above says: "Ensuring these bits are 0 clears playback static on some HD Audio codecs". Which is definitely true at least on my Core i5 Westmere system. Cc: Takashi Iwai <tiwai@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The software division functions never had unwinding annotations added. Currently, when a division by zero occurs the backtrace shown will stop at Ldiv0 or some completely unrelated function. Add unwinding annotations in hopes of getting a more useful backtrace when a division by zero occurs.

2011-05-27inetpeer: fix race in unused_list manipulationsEric Dumazet1-15/+27
Several crashes in cleanup_once() were reported in recent kernels. Commit d6cc1d642de9 (inetpeer: various changes) added a race in unlink_from_unused(). One way to avoid taking unused_peers.lock before doing the list_empty() test is to catch 0->1 refcnt transitions, using full barrier atomic operations variants (atomic_cmpxchg() and atomic_inc_return()) instead of previous atomic_inc() and atomic_add_unless() variants. We then call unlink_from_unused() only for the owner of the 0->1 transition. Add a new atomic_add_unless_return() static helper With help from Arun Sharma.

Adding support for the twl6025. Major difference in the twl6025 is the group functionality has been removed from the chip so this affects how regulators are enabled and disabled. The names of the regulators also changed. The DCDCs of the 6025 are software controllable as well. Since V1 Use the features variable passed via platform data instead of calling global function. Change the very switch like if statements to be a more readable switch statement. Since V2 twl6025 doesn't use remap so remove it from the macros. Since V3 enable/disable functions for 4030/6030 were seperated upstream so rebase on top of this. Change DCDC reference to SMPS as this is used in TRM. Change list_voltage slightly to have less code.

2011-05-27TPS65911: Comparator: Add comparator driverJorge Eduardo Candelaria2-0/+192
This driver adds functionality to the tps65911 chip driver. Two of the comparators are configurable by software and measures VCCS voltage to detect high or low voltage scenarios.

2011-05-27TPS65911: Add support for added GPIO linesJorge Eduardo Candelaria2-86/+33
GPIO 1 to 8 are added for TPS65911 chip version. The gpio driver now handles more than one gpio lines. Subsequent versions of the chip family can add new GPIO lines with minimal driver changes.

2011-05-27TPS65911: Add new irq definitionsJorge Eduardo Candelaria2-14/+75
TPS65911 adds new interrupt sources, as well as two new registers to handle them, one for interrupt status and one for interrupt masking. The added irqs are: -VMBCH2 - Low and High threshold -GPIO1-8 - Rising and falling edge detection -WTCHDG - Watchdog interrupt -PWRDN - PWRDN reset interrupt The code should handle these new registers only when the chip version is TPS65911.

2011-05-27regulator: tps65911: Add new chip versionJorge Eduardo Candelaria2-35/+332
The tps65911 chip introduces new features, including changes in the regulator module. - VDD1 and VDD2 remain unchanged. - VDD3 is now named VDDCTRL and has a wider voltage range. - LDOs are now named LDO1...8 and voltage ranges are sequential, making LDOs easier to handle.

2011-05-27MFD: TPS65910: Add support for TPS65911 deviceJorge Eduardo Candelaria2-1/+49
The TPS65911 is the next generation of the TPS65910 family of PMIC chips. It adds a few features: - Watchdog Timer - PWM & LED generators - Comparators for system control status It also adds a set of Interrupts and GPIOs, among other things. The driver exports a function to identify between different versions of the tps65910 family, allowing other modules to identify the capabilities of the current chip.

2011-05-27regulator: Remove ↵Axel Lin2-10/+6
MAX8997_REG_BUCK1DVS/MAX8997_REG_BUCK2DVS/MAX8997_REG_BUCK5DVS macros In current implementation, the original macro implementation assumes the caller pass the parameter starting from 1 (to match the register names in datasheet). Thus we have unneeded plus one then minus one operations when using MAX8997_REG_BUCK1DVS/MAX8997_REG_BUCK2DVS/MAX8997_REG_BUCK5DVS macros. This patch removes these macros to avoid unneeded plus one then minus one operations without reducing readability.
