* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-3/+5

Replace them with dev_request_mem_resource where possible.

| * of: use 'const void *' for struct of_device_id.dataAntony Pavlov2015-04-302-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | Registering mbus driver as platform driver is a little late for some register accesses to work. We have to make sure boot-up mbus windows are disabled early, so call mbus driver directly from SoC init.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current fixup code is slightly wrong, and only works when the root address cell number is one. However, Armada XP has a root address cell number of two. In this case we are currently applying the fixup on the child high base address, while it should be applied on the child low base address. Fix it and add some detailed explanation to avoid having to figure this out each time.

| | | | | | | | | | | | | | | | | | | | A resource_size is defined as res->end - res->start + 1. Marvell MBUS driver gets some ranges from DT as start and size but mis-calculates end of range.

| * ARM: mvebu: allow to fixup mbus rangesSebastian Hesselbarth2014-07-251-1/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Marvell MVEBU SoCs internal registers are usually remapped from reset default. While Dove and Kirkwood always had their registers remapped, some Armada 370 and XP where shipped with bootloaders that did not remap them. On Barebox these registers are remapped early and on all MVEBU SoCs, so provided DTs should always reflect that in their mbus ranges property. This patch registers a fixup for DTBs and allows individual SoCs to add specific remap ranges to the fixup list. The fixup is registered on pure_initcall to even allow to fixup pbl or appended DTBs.

* bus: mvebu: add mbus driverSebastian Hesselbarth2014-02-103-6/+757
| | | | | | | | | | | | This imports the Marvell mbus driver from Linux. The mbus is the main downstream bus found on all Marvell Orion SoCs. The driver deals with re-configurable address windows which are currently parsed from DT. Also enable the driver as default on all MVEBU SoCs.
