2020-04-21ARM: dts: am574x-idk: Disable m_can nodeFaiz Abbas-0/+4
Since commit bcbb63b80284 ("ARM: dts: dra7: Separate AM57 dtsi files"), the m_can node was inherited from dra76x.dtsi but the IP is not connected on the idk board. Disable the node to reflect this. Signed-off-by: Faiz Abbas <> Signed-off-by: Tony Lindgren <>
2019-11-20ARM: dts: am571x-idk: enable for new cpsw switch dev driverGrygorii Strashko-0/+5
Add DT nodes for new cpsw switchdev driver for am571x-idk board for now to enable testing of the new solution. Signed-off-by: Grygorii Strashko <> Signed-off-by: David S. Miller <>
2019-06-27ARM: dts: am57xx: Disable voltage switching for SD cardFaiz Abbas-6/+1
If UHS speed modes are enabled, a compatible SD card switches down to 1.8V during enumeration. If after this a software reboot/crash takes place and on-chip ROM tries to enumerate the SD card, the difference in IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card. The fix for this is to have support for power cycling the card in hardware (with a PORz/soft-reset line causing a power cycle of the card). Because the beaglebone X15 (rev A,B and C), am57xx-idks and am57xx-evms don't have this capability, disable voltage switching for these boards. The major effect of this is that the maximum supported speed mode is now high speed(50 MHz) down from SDR104(200 MHz). commit 88a748419b84 ("ARM: dts: am57xx-idk: Remove support for voltage switching for SD card") did this only for idk boards. Do it for all affected boards. Signed-off-by: Faiz Abbas <> Signed-off-by: Tony Lindgren <>
2019-04-12ARM: dts: dra7: Separate AM57 dtsi filesRoger Quadros-2/+2
AM5 and DRA7 SoC families have different set of modules in them so the SoC sepecific dtsi files need to be separated. e.g. Some of the major differences between AM576 and DRA76 DRA76x AM576x USB3 x USB4 x ATL x VCP x MLB x ISS x PRU-ICSS1 x PRU-ICSS2 x This patch only deals with disabling USB3, USB4 and ATL for AM57 variants.

The IO lines of MMC2 in am57xx-beagle-x15/am57xx-idk is connected to 3.3v. Use "ddr_3_3v" instead of "ddr_1_8v" to indicate DDR mode works in 3.3v on these boards. Signed-off-by: Kishon Vijay Abraham I <> Signed-off-by: Tony Lindgren <>
2018-05-03ARM: dts: am574x-idk: Add pinmux configuration for MMCSekhar Nori-0/+20
Include dra76x-mmc-iodelay.dtsi which has pinmux and IODelay configuration values for the various MMC modes for am574x SoC and use it in the pinctrl properties of MMC devicetree nodes present in am574x-idk.dts.

2017-12-21ARM: dts: am57xx: Add support for am574x-idkLokesh Vutla-0/+22
am574x-idk is similar to am572x-idk with am574x SoC. So create a common file for both evms and include SoC dtsi as needed. Signed-off-by: Lokesh Vutla <> Signed-off-by: Tony Lindgren <>
