* mci i.MX esdhc: Allow to specify devicename from platformdataSascha Hauer2012-12-171-0/+3
| | | | | | For boards which need to have persistent names for the device file. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci i.MX esdhc: turn error message into debug messageSascha Hauer2012-12-051-1/+1
| | | | | | | | During card probe the mci core may send commands to the card which the card doesn't understand. This is intended, so do not print an error message here. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * ARM i.MX: Remove old clock supportSascha Hauer2012-10-041-1/+0
| | | | | | | | | | | | | | The old clock support is now unused. Remove it. The former i.MX clko command is superseeded by generic clock manipulation commands. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

|/ | | | | | | | platform_driver/device_register now register_driver and register_device are for bus only usage. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>

| * Treewide: remove address of the Free Software FoundationSascha Hauer2012-09-171-4/+0
| | | | | | | | | | | | | | The FSF address has changed in the past. Instead of updating it each time the address changes, just drop it completely treewide. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* / mci imx-esdhc: increase write timeoutSascha Hauer2012-09-291-1/+1
|/ | | | | | | | | | The timeout for wating for the bus to be idle is too short when the card does internal garbage collection. This was triggered with filling an SD card under Linux with /dev/urandom, then doing a saveenv under barebox afterwards. Linux has timeouts here up to 300ms. Use a second to be safe.

* MMC i.MX esdhc: Fix sparse warningsSascha Hauer2012-06-301-10/+10

* mci i.MX esdhc: make 8bit modes platform dependentSascha Hauer2012-02-091-1/+5
| | | | | | | | Whether the controller works in 8bit mode is not only dependent on the controller but also on the board having wired up 8 data lines, so put a capabilities field in platform data. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci i.MX esdhc: use timeout loopsSascha Hauer2012-02-091-7/+20
| | | | | | | | Too often I have waited to get a reaction from this driver when something goes wrong. Use timeout loops instead of inifinite polling loops. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci: remove unused device argument from set_iosSascha Hauer2012-02-091-2/+1
| | | | | | This argmuent is unused in all drivers, so remove it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci core: replace discrete ios values with struct iosSascha Hauer2012-02-091-4/+12
| | | | | | | As we'll need more arguments to set_ios over time put them in a struct mci_ios like the kernel does. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* introduce io.hSascha Hauer2011-09-221-1/+1
| | | | | | | To allow for some generic io accessors introduce io.h and use this instead of asm/io.h throughout the tree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci: parent fixupsSascha Hauer2011-08-171-0/+1

* MCI imx-esdhc: Fix multiblock transfers on i.MX53Sascha Hauer2011-07-251-8/+13
| | | | | | | | | | | | | | | | | | | In the Kernel this bug is described like this: > The CMDTYPE of the CMD register (offset 0xE) should be set to > "11" when the STOP CMD12 is issued on imx53 to abort one > open ended multi-blk IO. Otherwise the TC INT wouldn't > be generated. > In exact block transfer, the controller doesn't complete the > operations automatically as required at the end of the > transfer and remains on hold if the abort command is not sent. > As a result, the TC flag is not asserted and SW received timeout > exeception. Bit1 of Vendor Spec registor is used to fix it. We do not use exact block transfers in barebox, so we only need the first part of this fix. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
