* OMAP4: Update ARM errata options.Kyle Repinski2014-10-031-3/+2
| | | | | | | | WARNING: NOT FOR OMAP4430! OMAP4460 apparently uses PL310 r3p1-50rel0, which according to the existing config docs and this link don't effect it: http://www.spinics.net/lists/arm-kernel/msg343612.html The newly added ones do effect it.

* OMAP4470: battery: correct temperature conversion.Oleksandr Dmytryshyn2014-10-011-0/+9
| | | | | | | | | | | TWL6032 has 12-bit ADC, TWL6030 has 10-bit ADC, battery temperature table is calculated for the TWL6030. So battery temperature measured correctly only for OMAP4430 and OMAP4460. Patch rejects two lower bits of ADC channel for TWL6032 and temperature measured correctly for all OMAP controllers.

| | | | | | | | | | | | | Battery driver reads ADC channel 1 to wich NTC resistor is connected to detect battery temperature. There is a table that matches ADC value to temperature. The driver, for looking corresponding temperature uses ADC value converted to millivolts, instead of ADC value, which is incorrect. Use ADC value for temperature conversion.

If the temperature is less then -2 degrees Celsius then -2 degrees Celsius returned and if the temperature is more then +62 degrees Celsius then +62 degrees Celsius returned.

* twl6030 battery: use gas gauge for capacity estimationAnand Gadiyar2014-10-011-0/+50
| | | | | | | | | | | | | | | | | | | | Use the gas gauge in twl6030 to estimate the remaining battery capacity. At bootup, we use an estimate of initial capacity using the measured battery voltage at bootup. From that point on, all future battery capacity estimations are done by using the gas gauge to measure all addition/removal of charge from the battery. Clamp battery value to 99% if the measured value exceeds 99%. A later patch will add the code to update the initial estimate once the battery is fully charged.

| | | | | | | | | | | | | | | | | Add a lookup table for estimating battery capacity at bootup using the battery voltage measrued at that time. The table was constructed using actual measured values for Blaze Tablets. The values don't correspond to the arbitrary values currently used in the driver. This table is something that a board file should pass to the driver. This will be introduced in a later patch - for now, we keep the values in the driver just like the current design.

* OMAP4430/60: EMIF: errata: Prohibit usage of Power-Down modeGrygorii Strashko2014-10-011-0/+38
| | | | | | | | | | | | | | | | | | | | | A ZQ calibration long command is issued every time on exit from active power-down and precharge power-down modes when EMIF is configured to use Power-down mode (EMIF_PWR_MGMT_CTRL.REG_LP_MODE=0x4). Due to very short periods of power-down cycles, ZQ calibration overhead creates bandwidth issues and increases overall system power consumption. As result, the guideline is to not allow Power-down mode and, therefore, to not have set the EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE bit field to 0x4.

* OMAP4: DPLL cascading: remove unused CM_SHADOW_FREQ_CONFIG2Eugen Mandrenko2014-10-011-42/+1
| | | | | | | | | | | | | | | The value from CM_SHADOW_FREQ_CONFIG2 can't be applied because GPMC is always active and can't be entered in idle state. The GPMC is always active because on OMAP4, CPU accesses on unmapped addresses are redirected to GPMC by L3 interconnect. CPU is speculative nature and such accesses are possible which can lead to indirect access to GPMC and if it's clock is not running, it can result in hang/abort on the platform. See path d60565948468b for more information. Change-Id: Ia62d8bf8c59ac3a06445b6f5f9e08ad0c9369c5b Signed-off-by: Eugen Mandrenko <ievgen.mandrenko@ti.com>
* ARM: OMAP4: omap-twl: Fix setting VSEL code for max_voltageOleg_Kosheliev2014-10-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | Errata ProDB00121179 says voltage overshoot may occur if switch from DVS to non-DVS ranges on TWL6032. - DVS range VSEL codes 0x01-0x39 - non-DVS range VSEL codes 0x3A-0x3E Max_volt settings (1.418V) were converted to VSEL=0x3A. This VSEL code is in non-DVS range while all other codes are in DVS range. Thus using this code leads to voltage overshoot due to errata. Now max_volt 1.418V is converted to code VSEL=0x39 which corresponds to 1.417960V and is in the safe range. The voltages higher than 1.418V aren't used for both 6030 and 6032. Thus replacing VSEL code 0x3A by 0x39 does not impact performance. If used SMPS_OFFSET=0 (default only for twl6030 es1.0 and is not used on twl6032) the max voltage of 1.35V is recalculated to VSEL=0x3A and is not affected by the patch.
