* | MFD: twl6040-codec: Add register cacheMisael Lopez Cruz2014-10-011-18/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add register cache and define register operations (read, write, set_bits, clear_bits) on cache only. So register operations performed on I2C registers are now differentiated. Register operations APIs exported by TWL6040 MFD are a wrapper to its I2C counterparts at the moment.

* | MFD: twl6040-codec: Add uEvent based event notificationChris Kelly2014-10-011-3/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | Add initial support for a kobject event based notification mechanism to inform userspace about TWL6040 events like handsfree overcurrent, vibrator overcurrent, thermal event. Since the events can be handled in other drivers apart from the MFD, a new API (twl6040_report_event) is created so that MFD clients can notify their events using a single kobject.

* | OMAP4: Regulator: Correct LDOs state in STATE_MEMOleksandr Dmytryshyn2014-10-011-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | All regulators have state_mem settings with flags 'enabled' and 'disabled'. If both flags have the same value (true or false) LDOs have incorrect setting and there are some warnings before entering the device to the sleep-mode. This patch correct settings for the LDO6, LDOLN and SYSEN for the TWL6032. Change-Id: I50b29ae503954826363279225b13967139106507 Signed-off-by: Oleksandr Dmytryshyn <oleksandr.dmytryshyn@ti.com>

* | MFD: twl6040-codec: Reinitialize completion in automatic power-upSivakumar Pothireddy2014-10-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TWL6040 automatic power-up sequence uses the completion interface. The completion is marked when CODEC driver receives the READYINT which indicates automatic sequence has finished. When the system is highly loaded it has been seen that the CODEC threaded interrupt handler (and complete() call) runs after timeout has expired. If the retry condition is met, then the call to wait_for_completion_timeout() will immediately return because of the previous completion. Therefore it's required to reinitialize the completion structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Turning off IO & PBIAS cells and then SD card VMMC as soon as we get disconnect interrupt. Failure to do so is causing current spikes (latch-up issue)which can potentially burn the I/O cells. Enabled Debounce logic in TWL6030 so that erroneous disconnect/connect interrupts will be suppressed. This will also fix issue where SD card disconnect event was not getting detected when SD card is very slowly plugged out.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.)

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.

| | | * mfd: Fix twl4030 dependencies for audio codecThomas Weber2011-11-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit f09ee0451a44a4e913a7c3cec3805508f7de6c54 upstream. The codec for Devkit8000 (TWL4030) was not detected except when build with CONFIG_SND_SOC_ALL_CODECS. twl-core.c still uses the CONFIG_TWL4030_CODEC for twl_has_codec(). In commit 57fe7251f5bfc4332f24479376de48a1e8ca6211 the CONFIG_TWL4030_CODEC was renamed into CONFIG_MFD_TWL4030_AUDIO, thatswhy the codec was not detected. This patch renames the CONFIG_ TWL4030_CODEC into CONFIG_MFD_TWL4030_AUDIO in twl-core.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During suspend/resume, TWL6040 is taking longer to complete automatic power-up sequence, so the timeout value is increased. This patch is to be reverted once the issue is root caused. Signed-off-by: Misael Lopez Cruz <misael.lopez@ti.com> Signed-off-by: Simon Wilson <simonwilson@google.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow TWL6040 MFD to make explicit use of external 32kHz clock. It's required for Power-On state, and can be disabled during Sleep state. Since external clocks might not be handled through clock framework, it's up to platforms/boards to implement the appropriate method as needed.
