* 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.

|/ | | | | | | | | | Upcoming patches will put I2C/SPI on their own busses with spi_register_driver / i2c_register_driver which will only be available if the subsystem is enabled. We could provide static inlines, but it wouldn't make much sense to compile a spi/i2c driver if the corresponding subsystem is disabled. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | This patch provide setup for SPI clk frequency global to driver. For MC13783 maximum clock frequency is 20 MHz, for MC13892 maximum clock frequency is 26 MHz, so we define 20 MHz as a maximum SPI clk.

| | | | | | | | | The mc13xxx driver correctly bails out on failure, but leaves mc_dev initialized, so a later mc13xxx_get won't fail but returns an invalid pointer. Fix this. While at it, remove some superfluous code from mc13xxx_get. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
