* of: use 'const void *' for struct of_device_id.dataAntony Pavlov2015-04-301-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* mfd: mc13xxx: move to coredevice_initcallSascha Hauer2014-05-191-11/+21
| | | | | | | | The PMIC is often a dependency for other devices, so make sure it's initialized early. While at it, merge the spi/i2c registration into a single initcall and use IS_ENABLED instead of ifdefs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mfd: mc13xxx: Allow to set callback for mc13xxxSascha Hauer2014-05-191-0/+18
| | | | | | | | | | | | | Some boards have to initialize the PMIC before other devices can be initialized. This requires three levels of initcalls: one level in which the PMIC is probed, one in which the board can call mc13xxx_get() and the third one to initialize the PMIC dependent devices. Allow to register a callback which is called once the PMIC is initialized. This way mc13xxx_get() is no longer necessary and the number of required initcalls levels is reduced to two.
