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.

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.

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.

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.

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).

The SSBI bus is exclusive to the Qualcomm MSM targets, and all SoCs using it will be using device tree. Convert this driver to indentify with device tree.

SSBI is the Qualcomm single-wire serial bus interface used to connect the MSM devices to the PMIC and other devices. Since SSBI only supports a single slave, the driver gets the name of the slave device passed in from the board file through the master device's platform data. SSBI registers pretty early (postcore), so that the PMIC can come up before the board init. This is useful if the board init requires the use of gpios that are connected through the PMIC. Based on a patch by Dima Zavin <dima@android.com> that can be found at: http://android.git.kernel.org/?p=kernel/msm.git;a=commitdiff;h=eb060bac4 This patch adds PMIC Arbiter support for the MSM8660. The PMIC Arbiter is a hardware wrapper around the SSBI 2.0 controller that is designed to overcome concurrency issues and security limitations. A controller_type field is added to the platform data to specify the type of the SSBI controller (1.0, 2.0, or PMIC Arbiter).
