2010-03-07mfd: Remove leftover from discontinued TWL4030 battery patchChristoph Egger2-25/+1
The TWL4030_BCI_BATTERY config option originates from a patch to the omap git tree. However inclusion in linux was seemingly rejected and the functionality nears inclusion under a different name so this removes the bits of the old version that made it into the mainline kernel again.

2010-03-07mfd: Fix debugfs code in AB3100 OTP driverLinus Walleij1-6/+7
This fixes the aged and unreachable debugfs code in the AB3100 OTP driver so that it's (A) reachable and (B) works. Bug detected in parallell by Christoph Egger using VAMOS and Robert P. J.

2010-03-07mfd: Use AB3100 MFD core IRQ for interrupt randomnessLinus Walleij2-10/+11
This reintroduces the entropy sampling of the AB3100 IRQ as the IRQF_SAMPLE_RANDOM is going out according to the feature removal schedule. I'm trying to do this the right way then, so CC:ing some random people for a quick review. We add entropy for interrupt events in the AB3100 which are truly random in nature, like external cables being connected, voltages on batteries dropping below certain ranges, ADC triggers or overheating.

2010-03-07mfd: Add HTCPLD driverCory Maccarrone4-0/+744
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: Support 88pm8606 in 860x driverHaojian Zhuang4-114/+203
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 Walleij2-33/+13
This converts the AB3100 core MFD driver to use a threaded interrupt handler instead of the explicit top/bottom-half construction with a workqueue.

2010-03-07mfd: Update WM8350 drivers for changed interrupt numbersMark Brown2-3/+3
The headphone detect and charger are using the IRQ numbers so need to take account of irq_base with the genirq conversion. I obviously picked the wrong system for initial testing. Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2010-03-07mfd: Don't allow WM8350 to be built modularMark Brown1-3/+3
The genirq implementation does not allow modules to implement irq_chips so the conversion of WM8350 to genirq means we can no longer allow the driver to be built as a module. Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2010-03-07mfd: Convert WM8350 to genirqMark Brown2-81/+118
This gives us use of the diagnostic facilities genirq provides and will allow implementation of interrupt support for the WM8350 GPIOs. Stub functions are provided to ease the transition of the individual drivers, probably after additional work to pass the IRQ numbers via the struct devices.

2010-03-07rtc: Suppress duplicate enable/disable of WM8350 update interruptMark Brown2-0/+8
Unlike the wm8350-custom code genirq nests enable and disable calls so we can't just unconditionally mask or unmask the interrupt, we need to remember the state we set and only mask or unmask when there is a real change.

2010-03-07mfd: Correct use after free for t7l66xbJulia Lawall1-1/+1
The structure t7l66xb should not be freed before the subsequent references to its fields in the arguments to clk_put. Furthermore, this structure is allocated near the beginning of the function, and a goto to the label err_noirq appears after a successful allocation, so it would seem that the kfree should be moved down below this label. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,e; identifier f; iterator I; statement S; @@ *kfree(x); ... when != &x when != x = e when != I(x,...) S *x->f // </smpl> Signed-off-by: Julia Lawall <[email protected]>

2010-03-07Revert "lib: build list_sort() only if needed"Linus Torvalds4-7/+1
This reverts commit a069c266ae5fdfbf5b4aecf2c672413aa33b2504. It turns ou that not only was it missing a case (XFS) that needed it, but perhaps more importantly, people sometimes want to enable new modules that they hadn't had enabled before, and if such a module uses list_sort(), it can't easily be inserted any more. So rather than add a "select LIST_SORT" to the XFS case, just leave it compiled in. It's not all _that_ big, after all, and the inconvenience isn't worth it.
