* mmc: f-sdh30: fix order of function calls in sdhci_f_sdh30_removeYangtao Li2023-08-151-4/+7

* mmc: sunplus: Fix error handling in spmmc_drv_probe()Harshit Mogalapalli2023-08-091-11/+3
| | | | | | | | | | | | | | | | | | When mmc allocation succeeds, the error paths are not freeing mmc. Fix the above issue by changing mmc_alloc_host() to devm_mmc_alloc_host() to simplify the error handling. Remove label 'probe_free_host' as devm_* api takes care of freeing, also remove mmc_free_host() from remove function as devm_* takes care of freeing.

* mmc: sunplus: fix return value check of mmc_add_host()Wei Chen2023-08-091-4/+12
| | | | | | | | | | | | | | | | | mmc_add_host() may return error, if we ignore its return value, 1. the memory allocated in mmc_alloc_host() will be leaked 2. null-ptr-deref will happen when calling mmc_remove_host() in remove function spmmc_drv_remove() because deleting not added device. Fix this by checking the return value of mmc_add_host(). Moreover, I fixed the error handling path of spmmc_drv_probe() to clean up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | For a completed request, after the mmc_blk_mq_complete_rq(mq, req) function is executed, the bitmap_tags corresponding to the request will be cleared, that is, the request will be regarded as idle. If the request is acquired by a different type of process at this time, the issue_type of the request may change. It further caused the value of mq->in_flight[issue_type] to be abnormal, and a large number of requests could not be sent. p1: p2: mmc_blk_mq_complete_rq blk_mq_free_request blk_mq_get_request blk_mq_rq_ctx_init mmc_blk_mq_dec_in_flight mmc_issue_type(mq, req) This strategy can ensure the consistency of issue_type before and after executing mmc_blk_mq_complete_rq.

| * ARM/mmc: Convert old mmci-omap to GPIO descriptorsLinus Walleij2023-05-241-2/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent change to the OMAP driver making it use a dynamic GPIO base created problems with some old OMAP1 board files, among them Nokia 770, SX1 and also the OMAP2 Nokia n8x0. Fix up all instances of GPIOs being used for the MMC driver by pushing the handling of power, slot selection and MMC "cover" into the driver as optional GPIOs. This is maybe not the most perfect solution as the MMC framework have some central handlers for some of the stuff, but it at least makes the situtation better and solves the immediate issue.

The code is currently using the cached status from the command IRQ in ->busy_status as a state to select what to do next: if this state is non-zero we are waiting for IRQs and if it is zero we treat the state as the starting point for a busy detect wait cycle. Make this explicit by creating a state machine where the ->busy_complete callback moves between three states. The Ux500 busy detect code currently assumes this order: we enable the busy detect IRQ, get a busy start IRQ, then a busy end IRQ, and then we clear and mask this IRQ and proceed. We insert debug prints for unexpected states. This works as before on most cards, however on a problematic card that is not working with busy detect, and which I have been debugging, the following happens a lot: [ 3.380554] mmci-pl18x 80005000.mmc: no busy signalling in time [ 3.387420] mmci-pl18x 80005000.mmc: no busy signalling in time [ 3.394561] mmci-pl18x 80005000.mmc: lost busy status when waiting for busy start IRQ This probably means that the busy detect start IRQ has already occurred when we start executing the ->busy_complete() callbacks, and the busy detect end IRQ is counted as the start IRQ, and this is what is causing the card to not be detected properly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The busy detect callback for Ux500 checks for an error in the status in the first if() clause. The only practical reason is that if an error occurs, the if()-clause is not executed, and the code falls through to the last if()-clause if (host->busy_status) which will clear and disable the irq. Make this explicit instead: it is easier to read.

This is because the card detection procedure is being managed from a workqueue, rather than synchronously from the mmc host's ->probe() routine. To allow the card detect to be synchronous, let's simply skip using the workqueue at the first initialization attempt from mmc_start_host().

The platforms that already have ICE support will use the API as library since there will not be a devicetree node, but instead they have reg range. In this case, the of_qcom_ice_get will return an ICE instance created for the consumer's device. But if there are platforms that do not have ice reg in the consumer devicetree node and instead provide a dedicated ICE devicetree node, theof_qcom_ice_get will look up the device based on qcom,ice property and will get the ICE instance registered by the probe function of the ice driver. The ICE clock is now handle by the new driver. This is done by enabling it on the creation of the ICE instance and then enabling/disabling it on SDCC runtime resume/suspend.

The workflow of the SD Express card in GL9767 is as below. 1. GL9767 operates in SD mode and set MMC_CAP2_SD_EXP flag. 2. If card is inserted, Host send CMD8 to ask the capabilities of the card. 3. If the card has PCIe capability, then init_sd_express() will be invoked. 4. If the card has been put in write protect state then the SD features supported by SD mode but not supported by PCIe mode, therefore GL9767 switch to SD mode. 5. If the card has not been put in write protect state then GL9767 switch from SD mode to PCIe/NVMe mode and mmc driver handover control to NVMe driver. 6. If card is removed, GL9767 will return to SD mode.

The hardware limitation is reasonable for below reasons: 1.Normal flow should set DMA working mode first, then do DMA-transfer-related configuration, such as system address. 2.The hardware limitation may avoid the software to configure wrong higher 32bit address at 32bits addressing mode although it is redundant. The change that set 32bits/64bits addressing mode before set ADMA address, has no side-effect to other host IPs for below reason: The setting order is reasonable and standard: DMA Mode setting first and then DMA address setting.

Define a new blk_mode_t instead for use in blkdev_get_by_{dev,path}, ->open and ->ioctl and stop abusing fmode_t.
