- Do not call hcd core adjust wakeup flag code. It may change wakeup flag, and cause port change detect(PCD) enable setting change. - For ID wakeup, it should not call host's fsl_usb_recover_hcd at ID interrupt. The coming ID switch event will resume host. - Do not need enable wakeup interrupt for host at platform driver resume routine, it may introduce unnessary wakeup interrupt during bus resume. The wakeup will be enabled again when usb host goes to controller again due to autosuspend. - When there is no gadget enabled, the otg port is still at host mode with interrupt enabled, so when male Micro-B to female A-type cable with usb device plugs in, there will be PCD interrupt before hcd core leaves suspend mode.

change to timeout semaphore to wait on irq. use no timeout semaphore have below issues: 1. since fbmem.c will hold the console_lock() before call PAN_DISPLAY ioictl, if have wrong happens on IPU, IRQ not come, any log printk will not ouput, it will become like a system hang, and developer don't know what's wrong. 2. semaphore don't have timeout, here we can't know irq not come, so hang it infintly. 3. semaphore lock and unlock in different context is a dangous operation. To fix these issue, use timedout version to wait on irq. But for better coding stly to align Kernel Coding Style Doc, better use complete to wait on irq, use semaphre little ugly.

2012-03-01ENGR00175261 - EPDC fb: Remove warning messages from EPDC initDanny Nold
- Remove screen update from probe function. This update is redundant. The update in mxc_epdc_fb_fw_handler() will update and show the tux logo if FB console is added, so this achieves the same effect as the update invocation that was removed. - Remove dmaengine_get(), because SDMA driver returns a failure when cycling through DMA channels. Since it is not essential to register with this call, it has been removed. dmaengine_put() also removed. - Added hw_inialization variable to track whether HW is in process of being initialized. In which case, we do not print an error message when an update is received. Signed-off-by: Danny Nold <dannynold@freescale.com>
2012-03-01mmc: block: add handling for two parallel block requests in issue_rw_rqPer Forlin
Change mmc_blk_issue_rw_rq() to become asynchronous. The execution flow looks like this: * The mmc-queue calls issue_rw_rq(), which sends the request to the host and returns back to the mmc-queue. * The mmc-queue calls issue_rw_rq() again with a new request. * This new request is prepared in issue_rw_rq(), then it waits for the active request to complete before pushing it to the host. * When the mmc-queue is empty it will call issue_rw_rq() with a NULL req to finish off the active request without starting a new request.

The way the request data is organized in the mmc queue struct, it only allows processing of one request at a time.

2012-03-01mmc: queue: let host controllers specify maximum discard timeoutAdrian Hunter
Some host controllers will not operate without a hardware timeout that is limited in value. However large discards require large timeouts, so there needs to be a way to specify the maximum discard size. A host controller driver may now specify the maximum discard timeout possible so that max_discard_sectors can be calculated. However, for eMMC when the High Capacity Erase Group Size is not in use, the timeout calculation depends on clock rate which may change. For that case Preferred Erase Size is used instead.

2012-03-01mmc: block: add checking of r/w command responseRussell King - ARM Linux

2012-03-01mmc: block: improve error recovery from command channel errorsRussell King - ARM Linux
Command channel errors fall into four classes: 1. The command was issued with the card in the wrong state 2. The command failed to be received by the card correctly 3. The cards response failed to be received by the host (CRC error) 4. The card failed to respond to the card For (1), in theory we should know that the card is in the correct state. However, a failed stop command (or other failure) may result in the card remaining in a data transfer state from the previous command. If we detect this condition, we try to recover by sending a stop command. For the initial commands (set block count and the read/write command) no data will have been transferred. All that we need deal with is retrying at this point. A failed stop command can be remedied as above. If we are unable to recover the card (eg, the card ignores our requests for status, or we don't recognise the error code) then we immediately fail the request.
