2010-03-07Driver core: create lock/unlock functions for struct deviceGreg Kroah-Hartman
In the future, we are going to be changing the lock type for struct device (once we get the lockdep infrastructure properly worked out) To make that changeover easier, and to possibly burry the lock in a different part of struct device, let's create some functions to lock and unlock a device so that no out-of-core code needs to be changed in the future. This patch creates the device_lock/unlock/trylock() functions, and converts all in-tree users to them.

2010-03-07sysfs: Document sysfs_attr_init and sysfs_bin_attr_initEric W. Biederman
I have added a new requirement to the external sysfs interface that dynamically allocated sysfs attributes must call sysfs_attr_init if lockdep is enabled. For the time being callying sysfs_attr_init is only mandatory if lockdep is enabled, so we can live with a few unconverted instances until we find them all. As this is part of the public interface of sysfs it is a good idea to document these pseudo functions so someone inspeciting the code can find out what has happened. Signed-off-by: Eric W.

2010-03-07sysfs: Use one lockdep class per sysfs attribute.Eric W. Biederman
Acknowledge that the logical sysfs rwsem has one instance per sysfs attribute with different locking depencencies for different attributes. There is a sysfs idiom where writing to one sysfs file causes the addition or removal of other sysfs files. Lumping all of the sysfs attributes together in one lock class causes lockdep to generate lots of false positives. This introduces the requirement that non-static sysfs attributes need to be initialized with sysfs_attr_init or sysfs_bin_attr_init. Strictly speaking this requirement only exists when lockdep is enabled, and when lockdep is enabled we get a bit fat warning if this requirement is not met. Signed-off-by: Eric W.

2010-03-07driver core: Add class_attr_string for simple read-only stringAndi Kleen
Several drivers just export a static string as class attributes. Use the new extensible attribute support to define a simple CLASS_ATTR_STRING() macro for this.

2010-03-07driver-core: Add attribute argument to class_attribute show/storeAndi Kleen
Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. This makes the class attributes the same as sysdev_class attributes and plain attributes. This will allow further cleanups in drivers. Full tree sweep converting all users. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-03-07sysfs: Add attribute array to sysdev classesAndi Kleen
Add a attribute array that is automatically registered and unregistered to struct sysdev_class. This is similar to what struct class has. A lot of drivers add list of attributes, so it's better to do this easily in the common sysdev layer. This adds a new field to struct sysdev_class. I audited the whole tree and there are no dynamically allocated sysdev classes, so this is fully compatible.

2010-03-07sysdev: Pass attribute in sysdev_class attributes show/storeAndi Kleen
Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. Similar to sysdev_attributes and normal attributes. This is a tree-wide sweep, converting everything in one go. No functional changes in this patch other than passing the new argument everywhere. Tested on x86, the non x86 parts are uncompiled.

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.

2010-03-07mfd: Add HTCPLD driverCory Maccarrone
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.

2010-03-07mfd: Add irq support in 88pm860xHaojian Zhuang
88PM860x is a complex PMIC device. It contains touch, charger, sound, rtc, backlight, led, and so on. Host communicates to 88PM860x by I2C bus. Use thread irq to support this usage case. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2010-03-07mfd: Support 88pm8606 in 860x driverHaojian Zhuang
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.

2010-03-07mfd: Convert AB3100 driver to threaded IRQLinus Walleij
This converts the AB3100 core MFD driver to use a threaded interrupt handler instead of the explicit top/bottom-half construction with a workqueue. This saves some code and make it more similar to other modern MFD drivers. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
