New IPC command supported in SCU FW for VBus power control. USB OTG driver will switch to such commands instead of direct access to PMIC register for safety and SCU FW will handle the actual work after got the request(IPC command). Due to this change, usb driver should wait more time for sync OTGSC with USBCFG by SCU. Update wait time from 2ms to 5ms.

OMAP4 supports 2 types of transceiver interface. 1. UTMI: The PHY is embedded within OMAP4. The transceiver functionality is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY functionality is embedded within the OMAP4430. There is no direct interactions between the MUSB controller and TWL6030 chip to communicate the session-valid, session-end and ID-GND events. It has to be done through a software by setting/resetting bits in one of the control module register of OMAP4430 which in turn toggles the appropriate signals to MUSB controller. The internal transceiver has functional clocks and powerdown bits to powerdown the PHY for power saving. Since there is no option available for having 2 transceiver drivers for one USB controller, internal PHY specific APIs are passed through plaform_data function pointers to use in the twl6030-usb transceiver driver. 2. ULPI interface is provided for off-chip transceivers.

* USB: otg: twl4030: fix phy initialization(v1)Ming Lei2010-09-201-27/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 461c317705eca5cac09a360f488715927fd0a927(into 2.6.36-v3) is put forward to power down phy if no usb cable is connected, but does introduce the two issues below: 1), phy is not into work state if usb cable is connected with PC during poweron, so musb device mode is not usable in such case, follows the reasons: -twl4030_phy_resume is not called, so regulators are not enabled i2c access are not enabled usb mode not configurated 2), The kernel warings[1] of regulators 'unbalanced disables' is caused if poweron without usb cable connected with PC or b-device. This patch fixes the two issues above: -power down phy only if no usb cable is connected with PC and b-device -do phy initialization(via __twl4030_phy_resume) if usb cable is connected with PC(vbus event) or another b-device(ID event) in twl4030_usb_probe. This patch also doesn't put VUSB3V1 LDO into active mode in twl4030_usb_ldo_init until VBUS/ID change detected, so we can save more power consumption than before. This patch is verified OK on Beagle board either connected with usb cable or not when poweron. [1]. warnings of 'unbalanced disables' of regulators.

* USB: otg: twl4030: fix wrong assumption of starting stateFelipe Balbi2010-08-231-1/+5
| | | | | | | | | | | | | | | | | The reset state of twl4030-usb is not sleeping, it starts up awaken and we need to disable it if we have booted with a disconnected cable to avoid over consumption on the default state. To avoid problems later, we read the current state of the transceiver from the PHY_PWR_CTRL register. The bootloader can, anyways, put the device to sleep before us. Tested on a custom OMAP board.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-304-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
