2007-02-04tifm_sd: use kmap_atomic instead of kmap for PIO data bufferAlex Dubov1-27/+25
Data buffer for PIO transfer used to be mapped in advance with kmap. Abolish it in favor of on-demand kmap_atomic. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-02-04tifm_sd: alter order of the states in the command handlerAlex Dubov1-20/+37
Previously, stop command was issued right after BRS (block received/sent) event. Stop command completion event could interfere with the card busy event, causing miscount of the written blocks. This patch ensures that stop command issued as last action for a particular command, after DMA sompletion event and written block count verification.

2007-02-04mmc: Add support for SDHC cardsPhilip Langdale2-29/+119
Thanks to the generous donation of an SDHC card by John Gilmore, and the surprisingly enlightened decision by the SD Card Association to publish useful specs, I've been able to bash out support for SDHC. The changes are not too profound: i) Add a card flag indicating the card uses block level addressing and check it in the block driver. As we never took advantage of byte-level addressing, this simply involves skipping the block -> byte translation when sending commands. ii) The layout of the CSD is changed - a set of fields are discarded to make space for a larger C_SIZE. We did not reference any of the discarded fields except those related to the C_SIZE. iii) Read and write timeouts are fixed values and not calculated from CSD values. iv) Before invoking SEND_APP_OP_COND, we must invoke the new SEND_IF_COND to inform the card we support SDHC.

2007-02-04mmc: Power quirk for ENE controllersDarren Salt1-3/+19
Support for these devices was broken for 2.6.18-rc1 and later by commit 146ad66eac836c0b976c98f428d73e1f6a75270d, which added voltage level support. This restores the previous behaviour for these devices by ensuring that when the voltage is changed, only one write to set the voltage is performed. It may be that both writes are needed if the voltage is being changed between two non-zero values or that it's safe to ensure that only one write is done if the hardware only supports one voltage; I don't know whether either is the case nor can I test since I have only the one SD reader (1524:0550), and it supports just the one voltage.

2007-02-04mmc: let host be parent of cardsPierre Ossman1-1/+1

2007-02-04mmc: replace host->card_busyPierre Ossman1-8/+8

2006-12-11AT91 MMC update for 2.6.19Andrew Victor1-17/+24
The driver is usable on the newer SAM9 processors so replace all text references to AT91RM9200 with just AT91. The controller bug where all the words are byte-swapped is fixed on the AT91SAM9 processors. The byte-swapping work-around therefore only needs to be done if cpu_is_at91rm9200(). [Original patch from Wojtek Kaniewski] The AT91RM9200 and AT91SAM9260 processors support two MMC/SD slots - the slot which is connected is now passed via the platform_data and the correct slot selected in the AT91_MCI_SDCR register. The driver should not be calling at91_set_gpio_output() since the VCC pin should have already been configured as an output in the processor/board setup code. The driver should call at91_set_gpio_value(). Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2006-12-08[PATCH] LOG2: Implement a general integer log2 facility in the kernelDavid Howells1-1/+1
This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

Modern SD cards support a clock speed of 50 MHz. Make sure we test for this capability and do the song and dance required to activate it.

2006-12-01mmc: Add support for mmc v4 wide-bus modesPhilip Langdale1-14/+37
This change adds support for the mmc4 4-bit wide-bus mode. The mmc4 spec defines 8-bit and 4-bit transfer modes. As we do not support any 8-bit hardware, this patch only adds support for the 4-bit mode, but it can easily be built upon when the time comes. The 4-bit mode is electrically compatible with SD's 4-bit mode but the procedure for turning it on is different. This patch implements only the essential parts of the procedure as defined by the spec. Two additional steps are recommended but not compulsory. I am documenting them here so that there's a record. 1) A bus-test mechanism is implemented using dedicated mmc commands which allow for testing the functionality of the data bus at the electrical level. This is pretty paranoid and they way the commands work is not compatible with the mmc subsystem (they don't set valid CRC values). 2) MMC v4 cards can indicate they would like to draw more than the default amount of current in wide-bus modes. We currently will never switch the card into a higher draw mode. Supposedly, allowing the card to draw more current will let it perform better, but the specs seem to indicate that the card will function correctly without the mode change. Empirical testing supports this interpretation. Signed-off-by: Philip Langdale <philipl@overt.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2006-12-01[PATCH] mmc: Add support for mmc v4 high speed modePhilip Langdale1-2/+119

The TI controller can only go up to 24MHz, but everything helps. Another person has taken this basic patch and used it on a Nokia 770 to get a bigger boost because that controller can run at 48MHZ.
