Fix the led device naming for the sdhci driver. The led class documentation defines the led name to have the form "devicename:colour:function" while not applicable sections should be left blank. To comply with the documentation the led device name is changed from "mmc*" to "mmc*::". Signed-off-by: NHelmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

This commit fixes the regression what was added by commit 088a78af "s3cmci: Support transfers which are not multiple of 32 bits." fifo_free() now returns amount of available space in FIFO buffer in bytes. But do_pio_write() writes to FIFO 32-bit words. Condition for return from cycle is (fifo_free() == 0), but when fifo has 1..3 bytes of free space then this condition will never be true and system hangs. This patch changes condition in the while() to (fifo_free() > 3).

With the PXA270 MMC hardware, there seems to be an issue of data corruption on writes where a 4KB data block is offset by one byte.

This patch adds support for the ST Microelectronics version of the PL180 PrimeCell. They use designer ID 0x80 and have a few alterations/bugfixes related to open drain and HW flow control. They also add some SDIO registers, I am unsure if these are in ST HW only or if this is things also added in later ARM revisions, but they are included in the mmci.h file for completeness.

This patch adds a MX2/MX3 specific SDHC driver. The hardware is basically the same as in the MX1, but unlike the MX1 controller the MX2 controller just works as expected. Since the MX1 driver has more workarounds for bugs than anything else I had no success with supporting MX1 and MX2 in a sane way in one driver.

Simply, if a client wants any dmaengine channel then prevent all dmaengine modules from being removed. Once the clients are done re-enable module removal. Why?, beyond reducing complication: 1/ Tracking reference counts per-transaction in an efficient manner, as is currently done, requires a complicated scheme to avoid cache-line bouncing effects. 2/ Per-transaction ref-counting gives the false impression that a dma-driver can be gracefully removed ahead of its user (net, md, or dma-slave) 3/ None of the in-tree dma-drivers talk to hot pluggable hardware, but if such an engine were built one day we still would not need to notify clients of remove events. The driver can simply return NULL to a ->prep() request, something that is much easier for a client to handle.

The latest generation of laptops are shipping with a newer model of Ricoh chip where the firewire controller is the primary PCI function but a cardbus controller is also present.

When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

The s3cmci driver uses the host->pio_ptr field to point to the current position into the buffer for data transfer. During the transfers it does the following: while (fifo_words--) *(host->pio_ptr++) = readl(from_ptr); This is inefficent, as host->pio_ptr is not used in any other part of the transfer but the compiler emits code which does the following: while (fifo_words--) { u32 *ptr = host->pio_ptr; *ptr = readl(from_ptr); ptr++; host->pio_ptr = ptr; } This is obviously a waste of a load and store each time around the loop, which could be up to 16 times depending on how much needs to be transfered. Move the ptr accesses to outside the while loop so that we do not end up reloading/re-writing the pointer. Note, this seems to make the code 16 bytes larger.

To be able to do SDIO the s3cmci driver has to support non-word-sized transfers. Change pio_words into pio_bytes and fix up all the places where it is used. This variant of the patch will not overrun the buffer when reading an odd number of bytes. When writing, this variant will still read past the end of the buffer, but since the driver can't support non-word- aligned transfers anyway, this should not be a problem, since a word-aligned transfer will never cross a page boundary. This has been tested with a CSR SDIO Bluetooth Type A device on a Samsung S3C24A0 processor.
