IDMAC may not be cleaned in driver probe if it has been already used in boot time. So IDMAC needs sw reset newly. And DMA interface reset precedes the internal DMAC reset. Additionally SDMMC_IDMAC_SWRESET is replaced with magic code.

DTO interrupt can be later than transmit interrupt(IDMAC) in case of write. Current handling of IDMAC interrupt sets EVENT_DATA_COMPLETE as well as EVENT_XFER_COMPLETE regardless of DTO rising. This makes the current request finish in tasklet and permits the next request even though current data transfer is still in progress. As a result, sequence is broken and lock-up happens. Setting EVENT_DATA_COMPLETE is not proper after IDMAC interrupt. It should be taken after DTO interrupt is generated.

3bdc9ba8 ("mmc: use really long write timeout to deal with crappy cards") in 3.4 increased the write timeout that the core sends to host drivers to 3 seconds. This makes sdhci's "requested timeout too large" warning trigger on every write; so, change this pr_warning() to a DBG().

First mci IPs (mainly on rm9200 and 9261) don't have the r/w proof capability.

The variable 'dw_mci_card_workqueue' is a global variable shared between multiple instances of the dw_mmc host controller. Due to this, data corruption has been noticed when multiple instances of dw_mmc controllers are actively reading/writing the media.

the current i.MX clock support groups together unrelated clocks to a single clock which is then used by the driver. This can't be accomplished with the generic clock framework so we instead request the individual clocks in the driver. For i.MX there are generally three different clocks: ipg: bus clock (needed to access registers) ahb: dma relevant clock, sometimes referred to as hclk in the datasheet per: bit clock, pixel clock This patch changes the driver to request the individual clocks. Currently all clk_get will get the same clock until the SoCs are converted to the generic clock framework Signed-off-by: NSascha Hauer <s.hauer@pengutronix.de>

This driver is broken since 2.6.31 when the traditional i.MX1 support was removed. In theory the i.MX1 mmc controller can be supported by the mxcmmc driver which basically is the same hardware. However, the i.MX1 controller has severe bugs which made several workarounds necessary which resulted in a different driver structure. At that time it seemed easier to write a second driver to support hardware without bugs. As noone cared for the i.MX1 driver for a long time and it does not compile, remove it.
