* of: use 'const void *' for struct of_device_id.dataAntony Pavlov2015-04-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 2011 barebox' of_device_id struct uses unsigned long type for data field: struct of_device_id { char *compatible; unsigned long data; }; Almost always struct of_device_id.data field are used as pointer and need 'unsigned long' casting. E.g. see 'git grep -A 4 of_device_id drivers/' output: drivers/ata/sata-imx.c:static __maybe_unused struct of_device_id imx_sata_dt_ids[] = { drivers/ata/sata-imx.c- { drivers/ata/sata-imx.c- .compatible = "fsl,imx6q-ahci", drivers/ata/sata-imx.c- .data = (unsigned long)&data_imx6, drivers/ata/sata-imx.c- }, { Here is of_device_id struct in linux kernel v4.0: struct of_device_id { char name[32]; char type[32]; char compatible[128]; const void *data; }; Changing of_device_id.data type to 'const void *data' will increase barebox' linux kernel compatibility and decrease number of 'unsigned long' casts. Part of the patch was done using the 'coccinelle' tool with the following semantic patch: @rule1@ identifier dev; identifier type; identifier func; @@ func(...) { <... - dev_get_drvdata(dev, (unsigned long *)&type) + dev_get_drvdata(dev, (const void **)&type) ...> } @rule2@ identifier dev; identifier type; identifier func; identifier data; @@ func(...) { <... - dev_get_drvdata(dev, (unsigned long *)&type->data) + dev_get_drvdata(dev, (const void **)&type->data) ...> } Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci: core: Check return value of dev_add_param_boolWadim Egorov2015-03-191-1/+2
| | | | | | | | | | | | Commit 03b59bdb64e83ebcdb9111681775117ebce0e03b changed the return values of dev_add_param_* to ERR_PTR(-ENOSYS) and broke a few boards. We have now to care about the return value of dev_add_param_bool() in mci_register(). Also set the ret variable when dev_add_param_bool() fails.

* mci: Fix version handlingSascha Hauer2014-02-141-9/+19
| | | | | | | | | | | | Currently the version defines reflect the digits in the version number. MMC_VERSION_4_41 is defined as 0x441 and MMC_VERSION_4_5 is defined as 0x405. This results in MMC_VERSION_4_5 < MMC_VERSION_4_41 becoming true which was surely not intended. Fix this by redefining the versions as 0x<major><minor><micro>. This makes the string generation more complicated but makes versions comparable again. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The eMMC and the SD-Card specifications describe the optional SET_DSR command. During measurements at our lab we found that some cards implementing this feature having really strong driver strengts per default. This can lead to voltage peaks above the specification of the host on signal edges for data sent from a card to the host. Since availability of a given card type may be shorter than the time a certain hardware will be produced it is useful to have support for this command (Alternative would be changing termination resistors and adapting the driver strength of the host to the used card.)
