* xhci: Remove segments from radix tree on failed insert.Sarah Sharp2014-03-041-26/+81
| | | | | | | | | | | | | | | | | | | | If we're expanding a stream ring, we want to make sure we can add those ring segments to the radix tree that maps segments to ring pointers. Try the radix tree insert after the new ring segments have been allocated (the last segment in the new ring chunk will point to the first newly allocated segment), but before the new ring segments are linked into the old ring. If insert fails on any one segment, remove each segment from the radix tree, deallocate the new segments, and return. Otherwise, link the new segments into the tree. HdG: Add a check to only update stream mappings in xhci_ring_expansion when the ring is a stream ring.

* xhci: For streams the dequeue ptr must be read from the stream ctxHans de Goede2014-03-042-7/+16
| | | | | | | | | | | | | | This fixes TR dequeue validation failing on Intel XHCI controllers with the following warning: Mismatch between completed Set TR Deq Ptr command & xHCI internal state. Interestingly enough reading the deq ptr from the ep ctx after a TR Deq Ptr command does work on a Nec XHCI controller, it seems the Nec writes the ptr to both the ep and stream contexts when streams are used.

* xhci: Check size rather then number of streams when allocating stream ctxsHans de Goede2014-03-041-8/+8
| | | | | | | | | | Before this a device needing ie 32 stream ctxs would end up with an entry from the small_streams_pool which has 256 bytes entries, where as 32 stream ctxs need 512 bytes. Things actually keep running for a surprisingly long time before crashing because of this.

* xhci: Free streams when they are still allocated on a set_interface callHans de Goede2014-03-041-1/+20
| | | | | | | | | | | | | | | | | And warn about this, as that would be a driver bug. Like wise drivers should ensure that streams are properly free-ed before a device is reset. So lets warn about that too. This already causes warnings in the form of: [ 96.982398] xhci_hcd 0000:01:00.0: WARN Can't disable streams for endpoint 0x81 , streams are already disabled! [ 96.982400] xhci_hcd 0000:01:00.0: WARN xhci_free_streams() called with non-streams endpoint But it is better to also warn about the actual cause of this later warnings.

* xhci: fix usb3 streamsGerd Hoffmann2014-03-042-43/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | xhci maintains a radix tree for each stream endpoint because it must be able to map a trb address to the stream ring. Each ring segment must be added to the ring for this to work. Currently xhci sticks only the first segment of each stream ring into the radix tree. Result is that things work initially, but as soon as the first segment is full xhci can't map the trb address from the completion event to the stream ring any more -> BOOM. You'll find this message in the logs: ERROR Transfer event for disabled endpoint or incorrect stream ring This patch adds a helper function to update the radix tree, and a function to remove ring segments from the tree. Both functions loop over the segment list and handles all segments instead of just the first. [Note: Sarah changed this patch to add radix_tree_maybe_preload() and radix_tree_preload_end() calls around the radix tree insert, since we can now insert entries in interrupt context. There are now two helper functions to make the code cleaner, and those functions are moved to make them static.] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>

* usb/xhci: Change how we indicate a host supports Link PM.Sarah Sharp2014-03-043-17/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The xHCI driver currently uses a USB core internal field, udev->lpm_capable, to indicate the xHCI driver knows how to calculate the LPM timeout values. If this value is set for the host controller udev, it means Link PM can be enabled for child devices under that host. Change the code so the xHCI driver isn't mucking with USB core internal fields. Instead, indicate the xHCI driver doesn't support Link PM on this host by clearing the U1 and U2 exit latencies in the roothub SuperSpeed Extended Capabilities BOS descriptor. The code to check for the roothub setting U1 and U2 exit latencies to zero will also disable LPM for external devices that do that same. This was already effectively done with commit ae8963adb4ad8c5f2a89ca1d99fb7bb721e7599f "usb: Don't enable LPM if the exit latency is zero." Leave that code in place, so that if a device sets one exit latency value to zero, but the other is set to a valid value, LPM is only enabled for the U1 or U2 state that had the valid value. This is the same behavior the code had before. Also, change messages about missing Link PM information from warning level to info level. Only print a warning about the first device that doesn't support LPM, to avoid log spam. Further, cleanup some unnecessary line breaks to help people to grep for the error messages.

Fixes to 2 Capella light sensor drivers where the units of the integration time reported to userspace were out be a factor of a thousand. These patches are as large as they are purely due to a variable rename tied up with the incorrect scale. The actual change is only a couple of lines. 1 patch dropping L3GD20H from the st gyroscope driver. It never actually worked as the address set is different from any others supported by the driver currently. An additional patch enables correct support for this part but is too large to sensibly apply as a fix to some support that never actually allowed the driver to be successfully probed on this part.

The correct value of L3GD20H wai is 0xd7 instead of 0xd4. Dropped support for the sensor.

But cm32181_read_als_it function return IIO_VAL_INT. So fixed to return IIO_VAL_INT_PLUS_MICRO. Next, add .write_raw_get_fmt callback function for call iio_str_to_fixpoint. v2: cm32181_write_als_id function fixed as it was.

But, print more then the thousand second. when call *_integration_time attribute. Because read_integration_time function return IIO_VAL_INT. read integration time function is changed return IIO_VAL_INT_PLUS_MICRO; And then .write_raw_get_fmt callback function for parse a fixed-point number from a string.

A single line patch fixing a regression that was introduced in 3.13 in the reworking of the mxs touch screen and ADC drivers to be interrupt rather than polling driven. It resulted in a stray double reporting of the release coordinate in the touch screen driver. The bug lay in the adc side of the driver which left the statemachine in the wrong state.

Due to this the release coordinate will be reported again by accident when the next touchscreen event happens. This change sets up the correct state when waiting for the next touchscreen event. This has led to reported issues with calibrating the touchscreen. Bug was introduced somewhere in the series that began with 18da755de59b406ce2371a55fb15ed676eb08ed2 Staging/iio/adc/touchscreen/MXS: add proper clock handling in which the way this driver worked was substantially changed to be interrupt driven rather than relying on a busy loop. This was a regression in the 3.13 kernel.
