| | | | | | | | | | | The original author provided a random return value check which is redundant and seemingly floating.

* mfd: Always assign of_node in mfd_add_device()Stephen Warren2014-01-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | mfd_add_device() assigns .of_node in the device objects it creates only if the mfd_cell for the device has the .of_compatible field set and the DT node for the top-level MFD device contains a child whose compatible property matches the cell's .of_compatible field. This leaves .of_node unset in many cases. When this happens, entries in the DT /aliases property which refer to the top-level MFD DT node will never match the MFD child devices, hence causing the requested alias not to be honored. Solve this by setting each MFD child device's .of_node equal to the top- level MFD device's .of_node field in the cases where it would otherwise remain unset. The first use-case for this will be aliases for the TPS6586x's RTC device. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

* regulator: tps6586x: Add and use correct voltage tableStefan Agner2014-01-211-19/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Depending on the regulator version, the voltage table might be different. Use version specific regulator tables in order to select correct voltage table. For the following regulator versions different voltage tables are now used: * TPS658623: Use correct voltage table for SM2 * TPS658643: New voltage table for SM2 Both versions are in use on the Colibri T20 module. Make use of the correct tables by requesting the correct SM2 voltage of 1.8V. This change is not backward compatible since an old driver is not able to correctly set that value. The value 1.8V is out of range for the old driver and will refuse to probe the device. The regulator starts with default settings and the driver shows appropriate error messages. On Colibri T20, the old value used to work with TPS658623 since the driver applied a wrong voltage table too. However, the TPS658643 used on V1.2 devices uses yet another voltage table and those broke that pseudo-compatibility. The regulator driver now has the correct voltage table for both regulator versions and those the correct voltage can be used in the device tree.

| * mfd: input: iio: ti_amm335x: Rework TSC/ADC synchronizationSebastian Andrzej Siewior2014-01-072-28/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ADC driver always programs all possible ADC values and discards them except for the value IIO asked for. On the am335x-evm the driver programs four values and it takes 500us to gather them. Reducing the number of conversations down to the (required) one also reduces the busy loop down to 125us. This leads to another error, namely the FIFOCOUNT register is sometimes (like one out of 10 attempts) not updated in time leading to EBUSY. The next read has the FIFOCOUNT register updated. Checking for the ADCSTAT register for being idle isn't a good choice either. The problem is that if TSC is used at the same time, the HW completes the conversation for ADC *and* before the driver noticed it, the HW begins to perform a TSC conversation and so the driver never seen the HW idle. The next time we would have two values in the FIFO but since the driver reads everything we always see the current one. So instead of polling for the IDLE bit in ADCStatus register, we should check the FIFOCOUNT register. It should be one instead of zero because we request one value. This change in turn leads to another error. Sometimes if TSC & ADC are used together the TSC starts generating interrupts even if nobody actually touched the touchscreen. The interrupts seem valid because TSC's FIFO is filled with values for each channel of the TSC. This condition stops after a few ADC reads but will occur again. Not good. On top of this (even without the changes I just mentioned) there is a ADC & TSC lockup condition which was reported to me by Jeff Lance including the following test case: A busy loop of "cat /sys/bus/iio/devices/iio\:device0/in_voltage4_raw" and a mug on touch screen. With this setup, the hardware will lockup after something between 20 minutes and it could take up to a couple of hours. During that lockup, the ADCSTAT register says 0x30 (or 0x70) which means STEP_ID = IDLE and FSM_BUSY = yes. That means the hardware says that it is idle and busy at the same time which is an invalid condition. For all this reasons I decided to rework this TSC/ADC part and add a handshake / synchronization here: First the ADC signals that it needs the HW and writes a 0 mask into the SE register. The HW (if active) will complete the current conversation and become idle. The TSC driver will gather the values from the FIFO (woken up by an interrupt) and won't "enable" another conversation. Instead it will wake up the ADC driver which is already waiting. The ADC driver will start "its" conversation and once it is done, it will enable the TSC steps so the TSC will work again. After this rework I haven't observed the lockup so far. Plus the busy loop has been reduced from 500us to 125us. The continues-read mode remains unchanged.

| * mfd: ti_am335x_tscadc: Don't read back REG_SESebastian Andrzej Siewior2014-01-073-8/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The purpose of reg_se_cache has been defeated. It should avoid the read-back of the register to avoid the latency and the fact that the bits are reset to 0 after the individual conversation took place. The reason why this is required like this to work, is that read-back of the register removes the bits of the ADC so they do not start another conversation after the register is re-written from the TSC side for the update. To avoid the not required read-back I introduce a "set once" variant which does not update the cache mask. After the conversation completes, the bit is removed from the SE register anyway and we don't plan a new conversation "any time soon". The current set function is renamed to set_cache to distinguish the two operations. This is a small preparation for a larger sync-rework.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds max14577 core/irq driver to support MUIC(Micro USB IC) device and charger device and support irq domain method to control internal interrupt of max14577 device. Also, this patch supports DT binding with max14577_i2c_parse_dt(). The MAXIM 14577 chip contains Micro-USB Interface Circuit and Li+ Battery Charger. It contains accessory and USB charger detection logic. It supports USB 2.0 Hi-Speed, UART and stereo audio signals over Micro-USB connector. The battery charger is compliant with the USB Battery Charging Specification Revision 1.1. It has also SFOUT LDO output for powering USB devices.

This allows proper waking from suspend to RAM and also fixes broken interrupts after resuming: [ 42.705703] sec_pmic 7-0066: Failed to read IRQ status: -5 Interrupts stop working after first resume initiated by them (e.g. by RTC Alarm interrupt) because interrupt registers were not cleared properly. When device is woken up from suspend by RTC Alarm, an interrupt occurs before resuming I2C bus controller. The interrupt is handled by regmap_irq_thread which tries to read RTC registers. This read fails (I2C is still suspended) and RTC Alarm interrupt is disabled. Disable the S5M8767 interrupts during suspend (disable_irq()) and enable them during resume so the device will be still woken up but the interrupt won't happen before resuming I2C bus.
