| * | | mmc: mxs: fix card detection function for broken card detectDaniel Willmann2014-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Return -ENOSYS in get_cd if broken-cd is specified in the device tree. Commit a91fe279ae75 (mmc: mxs: use standard flag for broken card detection) sets MMC_CAP_NEEDS_POLL when broken-cd is specified. This driver sets this flag unconditionally as it does not support a card detect interrupt. Instead, broken-cd means that there is no card detect signal connected. The mmc core checks the get_cd function return value to determine if a card is present. Only for a non-zero return value it will attempt to initialize the card. So retuning -ENOSYS will allow the card to be initialized. For comparison, mmc_gpio_get_cd in slot-gpio.c also returns -ENOSYS if the card detect GPIO is not valid.

In this case we should not wait for a PRG_DONE IRQ after sending the stop command: it will not get raised when the busy flag is not set, causing the request to fail with a timeout.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds HS400 mode support for eMMC5.0 device. HS400 mode is high speed DDR interface timing from HS200. Clock frequency is up to 200MHz and only 8-bit bus width is supported. In addition, tuning process of HS200 is required to synchronize the command response on the CMD line because CMD input timing for HS400 mode is the same as HS200 mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SDIO controllers found on Marvell Kirkwood SoCs seem to cause a late, spurious irq although all interrupts have been disabled. This irq doesn't do any harm, neither to HW nor driver. To avoid some "unexpected irq" warning later, we workaround above issue by bailing out of irq handler early, if we didn't expect any.

Signalling is not required to begin at 3.3v and, if the host and card both support a particular VCC/VCCQ combination, it can be used immediately. In contrast, SD Cards must begin with 3.3v signalling and may switch to a lower voltage signalling if instructed to do so in CMD11. A message is required to coordinate this operation because the card only receives a 3.3v VDD and must know when to use the 1.8v produced by its internal regulator. It makes sense for the core to begin with 3.3v signalling but when that can't be set, 1.8v and 1.2v signalling also should be attempted. This is especially important when an external regulator with a limited range is used to supply VCCQ to an eMMC part.

This means the sdio func device will be suspend before the card device and thus resumed after. The consequence are the mmc core don't explicity need to protect itself from receiving sdio requests in suspended state. Instead that can be handled from the sdio bus, which is thus invokes the PM callbacks instead of old dummy function. In the case were the sdio func driver don't implement the PM callbacks the mmc core will in the early phase of system suspend, remove the card from the driver model and thus power off it.
