* tifm_sd: restructure initialization, removal and command handlingAlex Dubov2007-02-041-95/+110
| | | | | | | | | | | | | | | | | | | In order to support correct suspend and resume several changes were needed: 1. Switch from work_struct to tasklet for command handling. When device suspend is called workqueues are already frozen and can not be used. 2. Separate host initialization code from driver's probe and don't rely on interrupts for host initialization. This, in turn, addresses two problems: a) Resume needs to re-initialize the host, but can not assume that device interrupts were already re-armed. b) Previously, probe will return successfully before really knowing the state of the host, as host interrupts were not armed in time. Now it uses polling to determine the real host state before returning. 3. Separate termination code from driver's remove. Termination may be caused by resume, if media changed type or became unavailable during suspend. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm_sd: fix hardware timeout setupAlex Dubov2007-02-041-8/+7

* tifm_sd: Switch software timeout handler from work_struct to timerAlex Dubov2007-02-041-21/+13
| | | | | | | | | | | Two changes are introduced to software timeout handler in order to simplify its management: 1. The implementation is switched from work_struct to timer 2. Previously, software timeout was rearmed with each interrupt. Now, current request must complete entirely within timeout interval.

* tifm_sd: alter order of the states in the command handlerAlex Dubov2007-02-041-20/+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.

* mmc: Add support for SDHC cardsPhilip Langdale2007-02-042-29/+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.

* mmc: Power quirk for ENE controllersDarren Salt2007-02-041-3/+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.

* AT91 MMC update for 2.6.19Andrew Victor2006-12-111-17/+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>

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.

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>
| | * | [PATCH] mmc: Add support for mmc v4 high speed modePhilip Langdale2006-12-011-2/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the high-speed modes defined by mmc v4 (assuming the host controller is up to it). On a TI sdhci controller, it improves read speed from 1.3MBps to 2.3MBps. 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.
