* clk: of: fix clk_of_table generationSascha Hauer2015-06-112-2/+3
| | | | | | | | | | | | | | We used to collect all sections beginning with __clk_of_table_ in a single section in the linker using KEEP(*(.__clk_of_table_*)). That the sentinel entry ended up as the last entry was pure luck, but not always the case. Instead of putting all entries in different sections we now put all entries in the same section. Only the sentinel entry gets its own section and is collected by the linker separately.

| * state: backend: support phandle and of_path referencesMarc Kleine-Budde2015-05-151-3/+4
| | | | | | | | | | | | | | | | | | | | | | This patch improves the backend property, it can be either a phandle or a of_path. During probe() of the state driver the backend property is dereferenced and the resulting of_path is saved in the state context. In a later patch it will be used to generate a phandle reference to the backend during DT fixup.

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.

The linux kernel also uses this timeout value for the control packets. For the musb the increase in timeout helps successfully probing USB devices (at least on one test hardware), but on the other hand doesn't slow down the system, if there are no devices, i.e. the timeout never hits. That means, that the USB core correctly aborts instead of timing out. Why and how the 100ms was chosen in the first place, can not be deduced from the git history, just that it seems to work fine for most boards. Change USB_CNTL_TIMEOUT to 5000ms and replace all occurences of `USB_CNTL_TIMEOUT * x` with just `USB_CNTL_TIMEOUT`, as the timeout is now large enough without it.
