drivers: Introduce dev_set_name()
...
Introduce dev_set_name() in order to hide implementation details of
setting device's name so it'd be easier to change it.

driver: replace dev_request_mem_region with dev_request_mem_resource
...
dev_request_mem_region doesn't work properly one some SoCs on which
PTR_ERR() values clash with valid return values from dev_request_mem_region.
Replace them with dev_request_mem_resource where possible.

of: use 'const void *' for struct of_device_id.data
...
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)

usb: musb: dsps: Do not use priv pointer
...
Use container_of instead of dev->priv pointer. dev->priv is
used by the musb core layer (which maybe should not be the
case, but using container_of is good anyway).

USB: MUSB: Add barebox specific changes
...
This changes the MUSB support from the original Kernel state to
be usable with barebox. Tested on a custom board and the Beaglebone
Black. The host port on the Beaglebone works, the OTG port works
in device mode, but not yet in host mode.
Based on the initial MUSB port from Rolf Evers Fischer.
