Define a truly synchronous API for the bus Tx path by putting all pending request to the write list and wait for the interrupt tx handler to wake us up. The ___mei_cl_send() out path is also slightly reworked to make it look more like main.c:mei_write(). Signed-off-by:

The pm8921 driver has been broken for a while now, but was prevented from compiling because the SSBI bus driver was missing. Now that SSBI is present, pm8921 causes compile fails. Until the pm8921 driver is fixed, mark it as BROKEN to prevent compiles from failing. Reported-by:

Merge tag 'arizona-extcon-asoc' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc into char-misc-next Mark writes: ASoC/extcon: arizona: Fix interaction between HPDET and headphone outputs This patch series covers both ASoC and extcon subsystems and fixes an interaction between the HPDET function and the headphone outputs - we really shouldn't run HPDET while the headphone is active. The first patch is a refactoring to make the extcon side easier.

Mark Brown authored
Running HPDET while the headphone outputs are enabled can disrupt the operation of HPDET. In order to avoid this HPDET needs to disable the headphone outputs and ASoC needs to not enable them while HPDET is running. For extcon instead of checking if the headphone output is enabled when doing magic application unconditionally disable the output and restore the state which ASoC wants set when undoing the magic.

Running HPDET while the headphone outputs are enabled can disrupt the operation of HPDET. In order to avoid this HPDET needs to disable the headphone outputs and ASoC needs to not enable them while HPDET is running. Do the ASoC side of this by storing the enable state in the core driver structure and only writing to the device if a flag indicating that the accessory detection side is in a state where it can have the headphone output stage enabled.

of_get_property returns value in Big Endian format. Before using this value it should be converted to little endian using be32_to_cpup(). Custom configs of emif are read from dt using of_get_property, but these are not converted to litte endian format. Correcting the same here. Signed-off-by:

ERRATA DESCRIPTION : The EMIF supports power-down state for low power. The EMIF automatically puts the SDRAM into power-down after the memory is not accessed for a defined number of cycles and the EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE bit field is set to 0x4. As the EMIF supports automatic output impedance calibration, a ZQ calibration long command is issued every time it exits active power-down and precharge power-down modes. The EMIF waits and blocks any other command during this calibration. The EMIF does not allow selective disabling of ZQ calibration upon exit of power-down mode. Due to very short periods of power-down cycles, ZQ calibration overhead creates bandwidth issues and increases overall system power consumption. On the other hand, issuing ZQ calibration long commands when exiting self-refresh is still required. WORKAROUND : Because there is no power consumption benefit of the power-down due to the calibration and there is a performance risk, the guideline is to not allow power-down state and, therefore, to not have set the EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE bit field to 0x4. This is applicable only for EMIF4D IP used in OMAP4 Soc's. Signed-off-by:

Some machine or kernel variants might have missed implementation of power off handlers. We DONOT want to let the system be in "out of spec" state in this condition. So, WARN and attempt a machine restart in the hopes of clearing the out-of-spec temperature condition. NOTE: This is not the safest option, but safer than leaving the system in unstable conditions.

As per JESD209-2E specification for LPDDR2, http://www.jedec.org/standards-documents/results/jesd209-2E Table 73, LPDDR2 memories come in two flavors - Standard and Extended. The Standard types can operate from -25C to +85C However, beyond that and upto +105C can only be supported by Extended types. Unfortunately, it seems there is no info in MR0(device info) or MR[1,2](device feature) for run time detection of this capability as far as seen on the spec. Hence, we provide a custom_config flag to be populated by platforms which have these "extended" type memories. For the "Standard" memories, we need to consider MR4 notifications of temperature triggers >85C as equivalent to thermal shutdown events (equivalent to Spec specified thermal shutdown events for "extended" parts).
