* ARM: i.MX27: Fix gpt compatible for latest device treesSascha Hauer2016-03-161-0/+3
| | | | | | | | In v4.2-rc3 the "fsl,imx1-gpt" compatible was replaced with "fsl,imx21-gpt" so i.MX27 currently ends up without clocksource. Fix this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* 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.

* ARM: imx: clocksource: add new DT compatibleStefan Christ2016-02-171-0/+3
| | | | | | | | | | Since commit 0ff58575c9d66 ("dts: update to v4.5-rc1") the compatible "fsl,imx6q-gpt" was removed from imx6dl.dtsi. Now there is only the Solo/DualLite specific compatible "fsl,imx6dl-gpt". Adapt the driver for that change.

* ARM: imx: clocksource: add new DT compatibleLucas Stach2015-10-261-0/+3
| | | | | | | | | | The i.MX6 DL/S DT has been changed to use more specific compatibles as GPTv2 has a different programming model for modes used in Linux. This difference doesn't matter for Barebox, but the old mx31 compatible has been dropped from the DT, so we need to match on the one still present.

* of: use 'const void *' for struct of_device_id.dataAntony Pavlov2015-04-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* ARM: i.MX clocksource: return successful for multiple instancesSascha Hauer2014-01-291-1/+1

* ARM: i.MX: Make timer available earlierSascha Hauer2013-06-181-1/+1
| | | | | | | | This moves the CCM drivers to core_initcall since this has no dependencies. This way we can be sure that the clock for the clocksource is available in at postcore_initcall time. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
