* ENGR00278646-11 mmc: sdhci-esdhc-imx: improve sd3.0 stabilityDong Aisheng2014-04-16
| | | | | | | | | | We observed on some sd3.0 cards(Toshiba SDHC U1) that it may require to reset host controller before sending the next tuning command or the tuning may fail and cause the card can not work on uhs mode. The root cause why the card fails on tuning without reset is still unknow. This could be treated as a workaround before finding root cause. Signed-off-by: Dong Aisheng <b29396@freescale.com>

* ENGR00278646-8 mmc: sdhci-esdhc: correct pre_div for imx6qDong Aisheng2014-04-16
| | | | | | | | | | According to spec, the pre_div for imx6q should be 1, or the biggest clock rate we can get is a half of host clock rate. This may cause we can not get the proper clock rate as we want. e.g. if the desired clock is 200Mhz, however, the host clock is 200Mhz too, then it causes the actual clock we get is 100Mhz due to pre_div is 2.

* ENGR00278646-6 sdhci: sdhci-esdhci-imx: add sd3.0 clock tuning supportDong Aisheng2014-04-16
| | | | | | | | | | | | | | | | | Freescale i.MX6Q/DL uSDHC clock tuning progress is a little different from the standard tuning process defined in host controller spec v3.0. Thus we use platform_execute_tuning instead of standard sdhci tuning. The main difference are: 1) not only generate Buffer Read Ready interrupt when tuning is performing. It generates all other DATA interrupts like the normal data command. 2) SDHCI_CTRL_EXEC_TUNING is not automatically cleared by HW, instead it's controlled by SW. 3) SDHCI_CTRL_TUNED_CLK is not automatically set by HW, it's controlled by SW. 4) the clock delay for every tuning is set by SW.

* ENGR00278646-4 sdhci: sdhci-esdhc-imx: support real clock on and off for imx6qDong Aisheng2014-04-16
| | | | | | | | | | | | | | | | | | The signal voltage switch follow requires to shutdown and output clock in a specific sequence according to standard host controller v3.0 spec. In that timing, the card must really receive clock or not. However, for i.MX6Q, the uSDHC will not output clock even the clock is enabled until there is command or data in transfer on the bus, which will then cause singal voltage switch always to fail. For i.MX6Q, we clear ESDHC_VENDOR_SPEC_FRC_SDCLK_ON bit to let controller to gate off clock automatically and set that bit to force clock output if clock is on. This is required by SD3.0 support.

* ENGR00278646-3 mmc: sdhci-esdhci: move common esdhc_set_clock to platform driverDong Aisheng2014-04-16
| | | | | | | | | | | | | We need a lot of imx6 specific things into common esdhc_set_clock for support SD3.0 and eMMC DDR mode which is not needed for power pc platforms, so esdhc_set_clock seems not so common anymore. Instead of keeping add platform specfics things into this common API, we choose to move that code into platform driver itself to handle. This can also exclude the dependency between imx and power pc on this headfile and is easy for maintain in the future. Signed-off-by: Dong Aisheng <b29396@freescale.com>

* mmc: sdhci: improve card removal check in sdhci_card_event()Shawn Guo2014-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9668d765eab78d58e656177db2acb57c249b9c01 upstream. The following error randomly appears on an imx6q board where gpio is used to implement card-detection when mounting EXT4 rootfs during boot. mmc1: Card removed during transfer! mmc1: Resetting controller. mmcblk0: unknown error -123 sending read/write command, card status 0x900 end_request: I/O error, dev mmcblk0, sector 106744 EXT4-fs error (device mmcblk0p2): ext4_find_entry:1312: inode #5011: comm swapper/0: reading directory lblock 0 It turns out that the error message comes from the card removal check in function sdhci_card_event(). While we have a well implemented function sdhci_do_get_cd() handling all the possible cases of CD, the current code only checks controller internal CD case. That causes problem for other CD cases like gpio on above imx6q board. Improve the check by using sdhci_do_get_cd() to cover all possible CD cases, so that above error on the imx6q board gets fixed.

* mmc: sdhci: request irq after sdhci_init() is calledShawn Guo2014-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generally request_irq() should be called after hardware has been initialized into a sane state. However, sdhci driver currently calls request_irq() before sdhci_init(). At least, the following kernel panic seen on i.MX6 is caused by that. The sdhci controller on i.MX6 may have noisy glitch on DAT1 line, which will trigger SDIO interrupt handling once request_irq() is called. But at this point, the SDIO interrupt handler host->sdio_irq_thread has not been registered yet. Thus, we see the NULL pointer access with wake_up_process(host->sdio_irq_thread) in mmc_signal_sdio_irq(). sdhci-pltfm: SDHCI platform and OF driver helper mmc0: no vqmmc regulator found mmc0: no vmmc regulator found Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = 80004000 [00000000] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.10.0+ #3 task: 9f860000 ti: 9f862000 task.ti: 9f862000 PC is at wake_up_process+0xc/0x44 LR is at sdhci_irq+0x378/0x93c ...

* mmc: atmel-mci: fix timeout errors in SDIO mode when using DMALudovic Desroches2014-02-13
| | | | | | | | | | | | | | | | commit 66b512eda74d59b17eac04c4da1b38d82059e6c9 upstream. With some SDIO devices, timeout errors can happen when reading data. To solve this issue, the DMA transfer has to be activated before sending the command to the device. This order is incorrect in PDC mode. So we have to take care if we are using DMA or PDC to know when to send the MMC command.

* mmc: fix host release issue after discard operationRay Jui2014-02-13
| | | | | | | | | | | | | | | | | | | | | commit f662ae48ae67dfd42739e65750274fe8de46240a upstream. Under function mmc_blk_issue_rq, after an MMC discard operation, the MMC request data structure may be freed in memory. Later in the same function, the check of req->cmd_flags & MMC_REQ_SPECIAL_MASK is dangerous and invalid. It causes the MMC host not to be released when it should. This patch fixes the issue by marking the special request down before the discard/flush operation.

* mmc: block: fix a bug of error handling in MMC driverKOBAYASHI Yoshitake2013-12-08
| | | | | | | | | | | | | | | | | | | | | | | commit c8760069627ad3b0dbbea170f0c4c58b16e18d3d upstream. Current MMC driver doesn't handle generic error (bit19 of device status) in write sequence. As a result, write data gets lost when generic error occurs. For example, a generic error when updating a filesystem management information causes a loss of write data and corrupts the filesystem. In the worst case, the system will never boot. This patch includes the following functionality: 1. To enable error checking for the response of CMD12 and CMD13 in write command sequence 2. To retry write sequence when a generic error occurs Messages are added for v2 to show what occurs.

* mmc: tmio_mmc_dma: fix PIO fallback on SDHISergei Shtylyov2013-09-26
| | | | | | | | | | | | | | | | | | | | commit f936f9b67b7f8c2eae01dd303a0e90bd777c4679 upstream. I'm testing SH-Mobile SDHI driver in DMA mode with a new DMA controller using 'bonnie++' and getting DMA error after which the tmio_mmc_dma.c code falls back to PIO but all commands time out after that. It turned out that the fallback code calls tmio_mmc_enable_dma() with RX/TX channels already freed and pointers to them cleared, so that the function bails out early instead of clearing the DMA bit in the CTL_DMA_ENABLE register. The regression was introduced by commit 162f43e31c5a376ec16336e5d0ac973373d54c89 (mmc: tmio: fix a deadlock). Moving tmio_mmc_enable_dma() calls to the top of the PIO fallback code in tmio_mmc_start_dma_{rx|tx}() helps.

* mmc: sdhci-esdhc-imx: fix multiblock reads on i.MX53Lucas Stach2013-05-26
| | | | | | | | | | | | | | | | | | | The eSDHC controller on the i.MX53 needs an additional, non spec compliant CMD12 after a multiblock read with a predefined number of blocks. Otherwise the internal state machine won't go back to the idle state. This commit effectively reverts 5b6b0ad6 (mmc: sdhci-esdhc-imx: fix for mmc cards on i.MX5), which fixed part of the problem by making multiblock reads work, however this fix was not sufficient when multi- and singleblock reads got intermixed. This implements the recommended workaround (Freescale i.MX Reference Manual, section 29.6.8 "Multi-block Read") by manually sending a CMD12 with the RSPTYP bits cleared.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently SDIO interrupts do not work on i.MX53 and maybe others. This was observed with a Marvell 8787 based SDIO wifi adapter using the mwifiex driver and firmware from the Marvell git repository. The symptom was a timeout after firmware download. Observing the SDIO_DAT1 line showed that an interrupt was requested (level 0) but no interrupt was generated in software, the line stayed low until a timeout ocurred and the card was reset. There is a Freescale errata ENGcm11186 "eSDHC misses SDIO interrupt when CINT is disabled" The workaround suggested by this errata is already implemented and involves clearing and then setting the D3CD bit in the host control register [see esdhc_writel_le()] However, when esdhc_writeb_le() is later used to write to SDHCI_HOST_CONTROL it always resets the D3CD bit. To fix this simply add the D3CD bit to the set of bits not modified by esdhc_writeb_le(). Signed-off-by: Martin Fuzzey <mfuzzey@parkeon.com> Signed-off-by: Chris Ball <cjb@laptop.org>

Since chained SDHC DMA transfers are not supported on mpc512x, limit 'max_segs' tunable parameter to one and initialise it to 64 only when running on i.MX platforms.
