2011-09-15OMAP: omap_device: decouple platform_device from omap_deviceKevin Hilman
Rather than embedding a struct platform_device inside a struct omap_device, decouple them, leaving only a pointer to the platform_device inside the omap_device. Use the arch-specific data field of the platform_device (pdev_archdata) to add an omap_device pointer after the platform_device has been created. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-09-15OMAP: omap_device: _disable_idle_on_suspend() takes platform_device pointerKevin Hilman
Public omap_device functions need to take platform_device pointers, conversion to omap_device pointers is done internal to the omap_device layer. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-09-15OMAP: omap_device: device register functions now take platform_device pointerKevin Hilman
The internal device register functions do not need or use any omap_device internals, so pass in a platform_device pointer instead of an omap_device pointer. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-09-15OMAP: omap_device: when building return platform_device instead of omap_deviceKevin Hilman
All of the device init and device driver interaction with omap_device is done using platform_device pointers. To make this more explicit, have omap_device return a platform_device pointer instead of an omap_device pointer. All current users of the omap_device pointer were only using it to get at the platform_device pointer or struct device pointer, so fixing all of the users was trivial. This also makes it more difficult for device init code to directly access members of struct omap_device, and allows for easier changing of omap_device internals.

2011-09-15OMAP: omap_device: remove internal functions from omap_device.hKevin Hilman

2011-09-15OMAP: omap_device: make latency autoadjust messages debugGrazvydas Ignotas
During normal system operation warning messages similar to this are appearing quite often: omap_device: omap4-keypad.-1: new worst case activate latency 0: 61035 This doesn't seem to be reporting a problem, nor is it very useful for non-developers, so reduce it to debug level.

2011-09-15OMAP: omap_device: replace debug/warning/error prints with dev_* macrosKevin Hilman
For consistency in kernel printk output for devices, use dev_dbg(), dev_warn(), dev_err() instead of pr_debug(), pr_warning() and pr_err(), some of which currently use direct access of name from platform_device and others of which use dev_name(). Using the dev_* versions uses the standard device naming from the driver core. Some pr_* prints were not converted with this patch since they are used before the platform_device and struct device are created so neither the dev_* prints or dev_name() is valid.

2011-09-15OMAP4: PM: TWL6030: add cmd registerNishanth Menon
Without the command register, ON/ONLP/RET/OFF voltages are useless. and TWL will be unable to use these Signed-off-by: Nishanth Menon <nm@ti.com>
2011-09-15OMAP4: PM: TWL6030: fix ON/RET/OFF voltagesPatrick Titiano
According to latest OMAP4430 Data Manual v0.4 dated March 2011: - Retention voltage shall be set to 0.83V. See tables 2.2, 2.4 and 2.6 in DM. This allows saving a little more power in retention states. - OPP100 IVA nominal voltage is 1.188V. See table 2.4 in DM. This allows saving a little power when CPU wakes up until Smart-Reflex is not yet resumed.

2011-09-15OMAP4: PM: TWL6030: fix uv to voltage for >0x39Nishanth Menon
using 1.35V as a check is not correct, we know that beyond 0x39, voltages are non linear - hence use the conversion iff uV greater than that for 0x39. For example, with 709mV as the smps offset, the max linear is actually 1.41V(0x39vsel)! Signed-off-by: Nishanth Menon <nm@ti.com>
2011-09-15OMAP4: PM: TWL6030: fix voltage conversion formulaPatrick Titiano
omap_twl_vsel_to_uv() and omap_twl_uv_to_vsel() functions used to convert voltages to TWL6030 SMPS commands (a.k.a "vsel") implement incorrect conversion formula. It uses legacy OMAP3 formula, but OMAP4 Power IC has different offset and voltage step: - Voltage Step is now 12.66mV (instead of 12.5mV) - Offset is either 607.7mV or 709mV depending on TWL6030 chip revision (instead of 600mV) This leads to setting voltages potentially higher than expected, and so potentially some (limited) power overconsumption. For reference, see formula and tables in section 8.5.2.3 "Output Voltage Selection (Standard Mode / Extended Mode with or without offset)" in TWL6030 functional specifications document.

2011-09-15OMAP2+: VC: more registers are per-channel starting with OMAP5Kevin Hilman
Starting with OMAP5, the following registers are per-channel and not common to a all VC channels: - SMPS I2C slave address - SMPS voltage register address offset - SMPS cmd/value register address offset - VC channel configuration register Move these from the channel-common struct into the per-channel struct to support OMAP5.

2011-09-15OMAP3+: voltage: update nominal voltage in voltdm_scale() not VC post-scaleKevin Hilman
Currently, the nominal voltage is updated in the VC post-scale function which is common to both scaling methods. However, this has readabiliy problems as this update is not where it might be expected. Instead, move the updated into voltdm_scale() upon a successful return of voltdm->scale() Signed-off-by: Kevin Hilman <khilman@ti.com>

combine VPCONFIG init voltage setup into common function and use from both vp_enable and from vp_forceupdate_scale(). NOTE: this patch changes the sequence of when the initVDD bit is cleared. The bit is now cleared immediately after it was written. Since only the rising edge of this bit has any affect according to the TRM, the exact timing of clearing of this bit should not have any effect. Signed-off-by: Kevin Hilman <khilman@ti.com>

2011-09-15OMAP: VP: Explicitly mask VPVOLTAGE fieldTodd Poynor

2011-09-15OMAP3+: VC: use last nominal voltage setting to get current_vselKevin Hilman
Instead of reading current vsel value from the VP's voltage register, just use current nominal voltage translated into vsel via the PMIC. Doing this allows VC bypass scaling to work even without a VP configured. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-09-15OMAP3+: PM: VC: handle mutant channel config for OMAP4 MPU channelKevin Hilman
On OMAP3+, all VC channels have the the same bitfield ordering for all VC channels, except the OMAP4 MPU channel. This appears to be a freak accident as all other VC channel (including OMAP5) have the standard configuration. Handle the mutant case by adding a per-channel flag to signal the deformity and handle it during VC init.

2011-09-15OMAP3+: VC: make I2C config programmable with PMIC-specific settingsKevin Hilman
Remove hard-coded I2C configuration in favor of settings that can be configured from PMIC-specific values. Currently only high-speed mode and the master-code value are supported, since they were the only fields currently used, but extending this is now trivial.

2011-09-15OMAP3+: VC: abstract out channel configurationKevin Hilman
VC channel configuration is programmed based on settings coming from the PMIC configuration. Currently, the VC channel to PMIC mapping is a simple one-to-one mapping. Whenever a VC channel parameter is configured (i2c slave addres, PMIC register address, on/ret/off command), the corresponding bits are enabled in the VC channel configuration register. If necessary, the programmability of channel configuration settings could be extended to board/PMIC files, however, because this patch changes the channel configuration to be programmed based on existing values from the PMIC settings, it may not be required. Also note that starting with OMAP4, where there are more than 2 channels, one channel is identified as the "default" channel. When any of the bits in the channel config for the other channels are zero, it means to use the default channel. The OMAP4 TRM (at least through NDA version Q) is wrong in describing which is the default channel. The default channel on OMAP4 is MPU, not CORE as decribed in the TRM.
