* bcm2835: introduce mach-bcm283xAlexander Aring2016-01-042-4/+4
| | | | | | | | | | | | This patch changes the most part of mach-bcm2835 to mach-bcm283x. This prepares to add RPi2 support which is a bcm2836. This patch changes the Kconfig entry namens to BCM283X for drivers only. These drivers should working the same in bcm2836. While updating defconfig I added LED support/trigger option.

* MCI: init device_node for MCI mainarea cdevLucas Stach2015-12-101-0/+3
| | | | | | | | | | | | | This fixes a regression, where boards specifying the environment path using the form device-path = &phandle, "partname:part" would be unable to find their env. This is due to of_find_path() switching to cdev_by_device_node() internally, which expects the device_node member of the main area cdev to be initialized.

* mci: dw_mmc: Add support for high speed modesTrent Piepho2015-11-191-0/+2
| | | | | | | | | | | | | | | | The Synopsys DesignWare core supports 52 MHz MMC mode and 50 MHz SD mode, so add the cap flags so they are used. This works on socfpga. The other user of this driver is Rockchip and the datasheet I found for the RK30xx indicated it supported highspeed modes as well. The Linux kernel has DT properties, e.g. "cap-mmc-highspeed", but none of the drivers in barebox support this at all. They all specify flags in their code.

* mci: dw_mmc: socfpga: Supply bus-width in platform_dataTrent Piepho2015-11-191-11/+13
| | | | | | | | | | | | | | | | | Since there is no OF support in the xloader on socfpga it uses the platform_data system. There needs to be a way to supply the equivalent of the DT property bus-width this way to support devices that need to use a smaller bus. So that we don't need to put every flag that might get added to the MMC_CAP list into platform_data, just put the bus width ones into platform_data. The socfpga dts sources specify a bus-width of 4 so use that in the platform_data for socfpga.

* mci: core: bus-width property should override driver defaultTrent Piepho2015-11-191-16/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | The OF code for parsing bus-width would only add the specified width to those the driver might have already set capability flags for. Because of this, if the driver had set 8 or 4 bit width, it wasn't possible for the DT to specify that fewer pins were used on the board and a smaller width was necessary. Change this so the width in the DT overrides whatever widths the driver says it supports. There is no reason to have an incorrect device tree and it makes far more sense for the DT to override the driver default than for the driver default to override the DT. The widths the driver puts in host_caps before calling mci_of_parse() are considered the default if the DT doesn't specify bus-width. This should cause the least amount of change to existing boards, as despite a comment that no bus-width meant to use 1 bit, using the driver default is what was really happening. Unfortunately, half of existing drivers default to the largest width they support while the other half default to the smallest. Boards should just stick the width in the device tree.

* 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>
