lcm() was defined to take integer-sized arguments. The supplied arguments are multiplied, however, causing us to overflow given sufficiently large input. That in turn led to incorrect optimal I/O size reporting in some cases (RAID over RAID). Switch lcm() over to unsigned long similar to gcd() and move the function from blk-settings.c to lib.

Use the completion interrupt generated by the device rather than polling for conversions to complete. As a backup we still check the status of the AUXADC if we don't get a completion, mostly for systems that don't have the WM831x interrupt infrastructure hooked up. Also reduce the timeout for completion of conversions to 5ms from the previous 10ms, the lower timeout should be sufficient.

New function twl4030_remove_script(u8 flags) takes a script type as defined in twl.h and prevents any script already loaded in that position from running. This is accomplished by programming SEQ_ADD_* to 0x3f, the END_OF_SCRIPT value, where SEQ_ADD_* is determined by flags. (Future) users of this function include OMAP board files for machines facing a race condition between sleep and warm reset.

Revision B of the WM831x devices changes the sense of the tristate bit for GPIO configuration, inverting it to become an enable instead. Take account of this in the gpiolib driver. A current sink regulation status bit has also been added in revision B, add a flag indicating if it's present but don't use it yet.

This patch disables TWL4030/5030 I2C1 adn I2C4(SR) internal pull-up, to use only the external HW resistor >=470 Ohm for the assured functionality in HS mode. While testing the I2C in High Speed mode, it was discovered that without a proper pull-up resistor, there is data corruption during multi-byte transfer. RTC(time_set) test case was used for testing. From the analysis done, it was concluded that ideally we need a pull-up of 1.6k Ohm(recomended) or atleast 470 Ohm or greater for assured performance in HS mode.

This change introduces a driver for the HTC PLD chip found on some smartphones, such as the HTC Wizard and HTC Herald. It works through the I2C bus and acts as a GPIO extender. Specifically: * it can have several sub-devices, each with its own I2C address * Each sub-device provides 8 output and 8 input pins * The chip attaches to one GPIO to signal when any of the input GPIOs change -- at which point all chips must be scanned for changes This driver implements the GPIOs throught the kernel's GPIO and IRQ framework. This allows any GPIO-servicing drivers to operate on htcpld pins, such as the gpio-keys and gpio-leds drivers.

88PM8606 and 88PM8607 are two discrete chips used for power management. Hardware designer can use them together or only one of them according to requirement. There's some logic tightly linked between these two chips. For example, USB charger driver needs to access both chips by I2C interface. Now share one driver to these two devices. Only one I2C client is identified in platform init data. If another chip is also used, user should mark it in companion_addr field of platform init data. Then driver could create another I2C client for the companion chip. All I2C operations are accessed by 860x-i2c driver. In order to support both I2C client address, the read/write API is changed in below. reg_read(client, offset) reg_write(client, offset, data) The benefit is that client drivers only need one kind of read/write API. I2C and MFD driver can be shared in both 8606 and 8607. Since API is changed, update API in 8607 regulator driver.

There are subsystems whose power management callbacks only need to invoke the callbacks provided by device drivers. Still, their system sleep PM callbacks should play well with the runtime PM callbacks, so that devices suspended at run time can be left in that state for a system sleep transition. Provide a set of generic PM callbacks for such subsystems and define convenience macros for populating dev_pm_ops structures. Signed-off-by: NRafael J. Wysocki <rjw@sisk.pl>

The current ELF dumper implementation can produce broken corefiles if program headers exceed 65535. This number is determined by the number of vmas which the process have. In particular, some extreme programs may use more than 65535 vmas. (If you google max_map_count, you can find some users facing this problem.) This kind of program never be able to generate correct coredumps. This patch implements ``extended numbering'' that uses sh_info field of the first section header instead of e_phnum field in order to represent upto 4294967295 vmas. This is supported by AMD64-ABI(http://www.x86-64.org/documentation.html) and Solaris(http://docs.sun.com/app/docs/doc/817-1984/). Of course, we are preparing patches for gdb and binutils.
