* da9053: add dt_ids to be probed by devicetreeMichael Grzeschik2017-01-101-0/+9
| | | | | | | | We add the da9052 compatible to get this driver probed by devicetree users. Signed-off-by: Michael Grzeschik <m.grzeschik@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* da9053: reset FAULTLOG after readMichael Grzeschik2017-01-101-0/+4
| | | | | | | | | | The driver has to reset the FAULTLOG register after every read by writing the value back. In the current case the FALUTLOG register keep its value over every software reset and will only reset on power-off. This drives the reset-source value unreliable.

| | | | | | | | | | | | | | | | | | | | | | | | Follow Linux Kernel change introduced in bdb0066df96e74a4002125467ebe459feff1ebef and avoid device/driver model for DT-based platforms. See the original kernel commit for the rationale. Also make syscon_base_lookup_by_pdevname() behave the same way as its kernel counterpart in the case whern "property" argument is NULL.

| | | | | | | | | | | | | | | | | | | | The preset SPI frequency for mc13xxx PMIC introduced with patch 6e18b3a48ee4 ("mc13xxx: Define maximum SPI clock frequency global to driver") is not desirable or working on all boards.

* | mfd: syscon: Don't call request_iomem_region()Andrey Smirnov2016-07-191-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On platforms that mix dedicated IP block register space with miscellaneous registers it is necessary to share register window between syscon and dedicated IP block driver. Calling request_iomem_region() implies exclusive ownership of the region, which, in the case above could not happen. This change also makes this driver's behaviour to that of its Linux kernel counterpart. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

|/ | | | | | | | | | | Fixing the i.MX6 specific issue this way breaks things on CLPS711x target. Better fix for the problem is to follow this patch.

* syscon: Decrease driver registration priorityAndrey Smirnov2016-05-181-1/+1
| | | | | | | | | | | | | | | A number of devices on i.MX6 list "syscon" as second compatibility string, among them, most importantly, is "iomuxv3" pinmux driver, which gets probed at "postcore_initcall". Probing this driver at "core_initcall" results in "syscon" driver usurping pinmux device and preventing "iomuxv3" driver from loading and correctly initializing pinmux of the system (which in turn results in a lot of sadness). Moving this driver to be initialized at "device_initcall" time resolves the issue. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* string: Fix (v)asprintf prototypesSascha Hauer2016-04-151-2/+2
| | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

* 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>

| | | | | | | | 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.
