2013-05-30mfd: adp5520: Restore mode bits on resumeLars-Peter Clausen
commit c6cc25fda58da8685ecef3f179adc7b99c8253b2 upstream. The adp5520 unfortunately also clears the BL_EN bit when the nSTNDBY bit is cleared. So we need to make sure to restore it during resume if it was set before suspend.

2013-01-03mfd: Only unregister platform devices allocated by the mfd coreCharles Keepax
commit b9fbb62eb61452d728c39b2e5020739c575aac53 upstream. mfd_remove_devices would iterate over all devices sharing a parent with an mfd device regardless of whether they were allocated by the mfd core or not. This especially caused problems when the device structure was not contained within a platform_device, because to_platform_device is used on each device pointer. This patch defines a device_type for mfd devices and checks this is present from mfd_remove_devices_fn before processing the device.

2012-08-19ARM: pxa: remove irq_to_gpio from ezx-pcap driverArnd Bergmann
commit 59ee93a528b94ef4e81a08db252b0326feff171f upstream. The irq_to_gpio function was removed from the pxa platform in linux-3.2, and this driver has been broken since. There is actually no in-tree user of this driver that adds this platform device, but the driver can and does get enabled on some platforms. Without this patch, building ezx_defconfig results in: drivers/mfd/ezx-pcap.c: In function 'pcap_isr_work': drivers/mfd/ezx-pcap.c:205:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Haojian Zhuang <haojian.zhuang@gmail.com> Cc: Samuel Ortiz <sameo@linux.intel.com> Cc: Daniel Ribeiro <drwyrm@gmail.com> Signed-off-by: Ben Hutchings <ben@decadent.org.uk>

2012-08-10random: make 'add_interrupt_randomness()' do something saneTheodore Ts'o
commit 775f4b297b780601e61787b766f306ed3e1d23eb upstream. We've been moving away from add_interrupt_randomness() for various reasons: it's too expensive to do on every interrupt, and flooding the CPU with interrupts could theoretically cause bogus floods of entropy from a somewhat externally controllable source. This solves both problems by limiting the actual randomness addition to just once a second or after 64 interrupts, whicever comes first. During that time, the interrupt cycle data is buffered up in a per-cpu pool. Also, we make sure the the nonblocking pool used by urandom is initialized before we start feeding the normal input pool. This assures that /dev/urandom is returning unpredictable data as soon as possible. (Based on an original patch by Linus, but significantly modified by tytso.)

2012-04-13mfd: Clear twl6030 IRQ status register only onceNishanth Menon
commit 3f8349e6e98ba0455437724589072523865eae5e upstream. TWL6030 family of PMIC use a shadow interrupt status register while kernel processes the current interrupt event. However, any write(0 or 1) to register INT_STS_A, INT_STS_B or INT_STS_C clears all 3 interrupt status registers. Since clear of the interrupt is done on 32k clk, depending on I2C bus speed, we could in-adverently clear the status of a interrupt status pending on shadow register in the current implementation. This is due to the fact that multi-byte i2c write operation into three seperate status register could result in multiple load and clear of status and result in lost interrupts. Instead, doing a single byte write to INT_STS_A register with 0x0 will clear all three interrupt status registers without the related risk.

2011-12-20mfd: Use request_threaded_irq for twl4030-irq instead of irq_set_chained_handlerNeilBrown
irq_set_chained_handler sets 'desc->handle_irq'. However this irq is called by handle_nested_irq from handle_twl4030_pih, and that uses action->thread_fn. So the handled set with irq_set_chained_handler is never called. So change to use request_threaded_irq instead - that sets the correct field. Tested on GTA04 Phoenux.

2011-10-24mfd: Convert db8500-prcmu panic() into pr_crit()Linus Walleij
panic() is too heavy for this, indeed the PRCMU is critical for the system but not to the point that we should stop everything, if we can still get a prompt or so. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2011-10-24mfd: Refactor db8500-prcmu request_clock() functionLinus Walleij
This refactors the mfd/dbx500-prcmu drivers to use a switch() statement rather than nested if/else-construction. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2011-10-24mfd: Rename db8500-prcmu init functionLinus Walleij
This renames the PRCMU clock force initialization function to have a less generic name. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2011-10-24mfd: Fix db5500-prcmu definesLinus Walleij

2011-10-24mfd: db8500-prcmu tweak for modem wakeupMattias Nilsson
This is a tweak for the case where the modem goes to sleep while emitting the AC_WAKE_ACK anyway. Also print the modem errors as critical, since they jeopardize the entire platform when they occur.

2011-10-24mfd: Move to the new db500 PRCMU APIMattias Nilsson
Now that we have a shared API between the DB8500 and DB5500 PRCMU's, switch to using this neutral API instead. We delete the parts of db8500-prcmu.h that is now PRCMU-neutral, and calls will be diverted to respective driver. Common registers are in dbx500-prcmu-regs.h and common accessors and defines in <linux/mfd/dbx500-prcmu.h> This way we get a a lot more abstraction and code reuse.

2011-10-24mfd: Initialize DB8500 PRCMU regsMattias Nilsson
Some clocks may be force enabled when we probe the driver, but they need to be turned off by default so we have a known state. We call this the register initialization function if we need more stuff in there in the future.
