2010-10-29OMAP: musb: Remove the omap_hwmod_lookup call in the interrupt disabled context.Hema HK
omap_hwmod_lookup() is not meant to be used in the interrupt disabled context. Calling this creates a problem as there is mutex_lock which might_sleep. Removed the usage of this function in the interrupt disabled context. Signed-off-by: Hema HK <hemahk@ti.com>
2010-10-29usb: musb:Fix for core retention with usb disabledHema HK
The internal phy is default put in operation mode which generates the 60MHz clock to musb. this will block the core retention incase of not enabling the usb. Powerdown the phy when there is no usb enabled. Signed-off-by: Hema HK <hemahk@ti.com>
2010-10-29omap4: l2x0: Set share override bit of Pl310Santosh Shilimkar
Clearing bit 22 in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
2010-10-11OMAP4: PM: Dynamically calculate vsel values for diff PMICRajendra Nayak
Different versions of twl6030 which can be used on various OMAP4430 based SDP's have different interpretation of vsel values. Hence dynamically populate the vsel values based on the twl6030 version rather than hardcoding. Signed-off-by: Rajendra Nayak <rnayak@ti.com>
2010-10-11Context save and restore of McBSP SYSCONFIG registerKishon Vijay Abraham I
When ABE power domain goes to retention, the contents of MCBSP is lost. The value of SYSCONFIG register in MCBSP is set to SMARTIDLE and ENWAKEUP by the hwmod framework. But once the ABE power domain goes to retention, the contents of MCBSP register is lost and set to reset values (NOIDLE and DISABLE WAKEUP). This patch creates two API's to save and restore the contents of MCBSP SYSCONFIG register. Save API is called in probe to save the content of SYSCONFIG register and restore API is called in request after pm_runtime_get_sync. Also omap_mcbsp_read() is modified to update the cache when reading from the register.

The musb_notifier_call function declaration was under CONFIG_PM check and the use was done unconditionally. Declared it outside the CONFIG_PM as this function will be used for non-pm build also.

changes. Disable the nop transciever call from the panda boardfile Enabled the OTG stack by default in omap_4430sdp_defconfig. Registered the notification for VBUS and IDGND events from TWL6030 OTG transciever. Handle the VBUS events(configure the control module register to set the session valid, VBUS valid and session end bits. Configure the control module IDGND bit to inform mentor controller about the change in IDGND. Wait for the mentor to be ready as A device or Bdevice based on the IDGND input,call the TWL6030 api to set the VBUS on/off. During port suspend enable the SUSPENDM to suspend the phy which will cut the 60MHz clock. This will allow the core domain transitioning to retention when device is supended. With this changes if the USB device is connected with micro converter (ID will be grounded) The the device will be enumerated as hosy. If the micro cable is connected to host, it is enumerated as device. Cleaned up the powerdown code as the phy powerdown will be handled based on the connect/disconnect events.

2010-10-06OMAP4: hmwod: Do not reset dsp at initRajendra Nayak
Since dsp/tesla today is not handled by syslink, making it come out of reset at hwmod init leaves it active and gates CHIP retention. Hence do not reset dsp during hwmod init. This patch can later be reverted once syslink does handle dsp/tesla and takes care of putting it to sleep once its not in use. Signed-off-by: Rajendra Nayak <rnayak@ti.com>

Each core sys/app were requesting gpt3/4, respectively, as bios timer source clock.

2010-10-06omap:iommu-event notification shouldn't be blocking callHari Kanigeri
iommu_notify_event function is called from interrupt context, and this function is using internally blocking_notifier_call_chain call that could sleep. The fix is changing blocking_notifier to raw_notifier and let the callers of the iommu_notify_event handle the protection. iommu_notify_event is used for 2 purposes. One is for MMU FAULT notification to the device handler where the devh sets the error state to Fault and prevents the broadcasting of any iommu close notifications. This shouldn't be blocking. Second, it is used to broadcast the notifications of the Process ID that closed the iommu handle to remote processor. This could be blocking.

2010-10-05OMAP4: PM: Enable Device RET supportRajendra Nayak
This patch configures VC on OMAP4 to enable Device RET support. The vc_config structure is updated to support additional VDD on omap4. This structure needs cleanup to use an ARRAY based on no of VDD's supported on platform. The prescale and count settings are conservative and needs a relook to optimize. They are also assumed to be independent of PMIC, if found otherwise they need to find a place in the vc_config struct as well. Signed-off-by: Rajendra Nayak <rnayak@ti.com>

2010-09-30OMAP: hwmod: Disable clocks when hwmod enable failsRajendra Nayak
In cases where a module(hwmod) does not become accesible on enabling the main clocks (can happen if there are external clocks needed for the module to become accesible), make sure the clocks are not left enabled. This ensures that when the requisite external depenedencies are met a omap_hwmod_enable and omap_hwmod_idle/shutdown would rightly enable and disable clocks using clk framework. Leaving the clocks enabled in the error case causes additional usecounting at the clock framework level leaving the clock enabled forever.
