* mmc: dw_mmc: Handle unaligned data submission correctlyMarkos Chandras2013-03-221-9/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit f9c2a0dc42a6938ff2a80e55ca2bbd1d5581c72e "mmc: dw_mmc: Fix PIO mode with support of highmem" introduced a regression since v3.2 making the mmc_test hang on test #13 with a "Data starvation by host timeout" interrupt. This is because, sg_mapping_iter is used to iterate through the data which spans on multiple pages. The problem is detected on unaligned data submission where the code previously checked for !(sg_next(host->sg)) which is true because we only have a single scatter/gather list which then expands to multiple pages. Therefore, the driver incorrectly assumed that this was the last list item and submitted unaligned data to the mmc device. This overflowed the FIFO on the device before all the data were written to it. The code was fixed to only submit unaligned data when we are handling the last sg_miter item by checking whether we reached the desired data length or not. The patch was tested against mmc_test and all the tests passed.

* mmc: dw_mmc: Don't loop when handling an interruptMarkos Chandras2013-03-221-7/+4
| | | | | | | | | | | | There is no reason to loop when handling an interrupt. The "if" clauses will handle all of them sequentially. This also eliminates the extra loop we used to take with no pending interrupts and we ended up breaking out of the while loop.

* mmc: dw_mmc: setpower on MMC_POWER_{UP,OFF}James Hogan2013-03-221-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Call the setpower platform callback in response to set_ios with ios->power_mode == MMC_POWER_UP or MMC_POWER_OFF, instead of from the card detect work function. This appears to fix a problem I have where a card stuck in a funny state doesn't get properly cleared by the power being turned off, presumably due to lack of power sequencing. This resulted in the following log messages after boot: mmc0: error -110 whilst initialising SD card mmc_host mmc0: Bus speed (slot 0) = 99840000Hz (slot req 300000Hz, actual 298922HZ div = 167) mmc0: error -110 whilst initialising SD card mmc_host mmc0: Bus speed (slot 0) = 99840000Hz (slot req 200000Hz, actual 199680HZ div = 250) mmc0: error -110 whilst initialising SD card mmc_host mmc0: Bus speed (slot 0) = 99840000Hz (slot req 195765Hz, actual 195764HZ div = 255) mmc0: error -110 whilst initialising SD card mmc_host mmc0: Bus speed (slot 0) = 99840000Hz (slot req 400000Hz, actual 399360HZ div = 125) mmc0: error -110 whilst initialising SD card mmc_host mmc0: Bus speed (slot 0) = 99840000Hz (slot req 300000Hz, actual 298922HZ div = 167) Signed-off-by: James Hogan <james.hogan@imgtec.com> Acked-by: Seungwon Jeon <tgih.jun@samsung.com> Acked-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Chris Ball <cjb@laptop.org>

* mmc: core: enhance card removal judgement for slow removalKevin Liu2013-03-221-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Function _mmc_detect_card_removed will be called to know whether the card is still present when host->bus_ops->detect is called. In current code, the return value of this function generally only depend on the result of sending cmd13 to card, which may not safe for card with detection support like slot gpio detection. Because the communication status between host and card may out of sync with the detect status if remove the card slowly or hands shake during the process. The direct reason is the async between card detect switch and card/slot pad contaction in hardware, which is defined by spec. The spec define card insert/remove sequence as below (both standard size SD card and MicroSD card have the same sequence): "Part 1 Standard Size SD Card Mechanical Addendum Ver4.00 Final, Appendix C: Card Detection Switch" (Take normally open type as example) a)SD card insertion sequence: The card detection switch should be turned on after all SD card contact pads are connected to the host connector contact pads. b)SD removal sequence: The card detection switch should be turned off when the SD card is just going to be removed and before any SD card contact pad is disconnected from the host connector contact pad. Below is the sequence when this issue occur (Take slot gpio detection as example and remove the card slowly during the process): 1. gpio level changed and card detect interrupt triggered. 2. mmc_rescan was launched. 3. the card pads were still contacted with the slot pads because of slow removal. So _mmc_detect_card_removed and mmc_rescan think card was still present (cmd13 succeed). 4. card pads were discontacted from the card slot pads. So the card was actually removed finally but the card removal event has been missed by system. The interval length between step 1 and step 4 depends on the card removal speed. If it's longer than the detect work schedule delay which is 200ms, this issue will likely happen. This patch add the card detect status check in function _mmc_detect_card_removed if cmd13 check succeed and host->ops->get_cd provided. If get_cd detect no card present then schedule another detect work 200ms later.

External SoC interrupts (from HWSTATEXT and friends) are vectored onto the TR2 core trigger for the current thread. This is demultiplexed in irq-metag-ext.c to individual Linux IRQs for each external SoC interrupt. The external irqchip has devicetree bindings for configuring the number of irq banks and the type of masking available.

That commit was written under the assumption that some controllers may take a very long time to turn off their async and periodic schedules. It now appears that in fact the schedules do get turned off reasonably quickly, but some controllers occasionally leave the schedules' status bits turned on and consequently ehci-hcd can't tell that the schedules are off. VIA controllers in particular have this problem. ehci-hcd tells the hardware to turn off the async schedule, the schedule does get turned off, but the status bit remains on. Since the EHCI spec requires that the schedules not be re-enabled until the previous disable has taken effect, with an unlimited timeout the async schedule never gets turned back on. The resulting symptom is that the system is unable to communicate with USB devices.
