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 Maccarrone3-0/+720
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 Zhuang3-90/+175
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: Don't allow WM8350 to be built modularMark Brown1-3/+3

2010-03-07mfd: Convert WM8350 to genirqMark Brown1-68/+87

2010-03-07rtc: Suppress duplicate enable/disable of WM8350 update interruptMark Brown1-0/+7

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 Torvalds1-1/+0
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.

2010-03-06usbfs: fix deadlock on 'usbfs_mutex', clean up pollLinus Torvalds1-42/+24
The caller of usbfs_conn_disc_event() in some cases (but not always) already holds usbfs_mutex, so trying to protect the event counter with that lock causes nasty deadlocks. The problem was introduced by commit 554f76962d ("USB: Remove BKL from poll()") when the BLK protection was turned into using the mutex instead. So fix this by using an atomic variable instead. And while we're at it, get rid of the atrocious naming of said variable and the waitqueue it is associated with. This also cleans up the unnecessary locking in the poll routine, since the whole point of how the pollwait table works is that you can just add yourself to the waiting list, and then check the condition you're waiting for afterwards - avoiding all races. It also gets rid of the unnecessary dynamic allocation of the device status that just contained a single word. We should use f_version for this, as Dmitry Torokhov points out. That simplifies everything further.
