* ARM: dts: stm32mp: report psci v0.2 at leastAhmad Fatoum2019-11-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | ARM TF-A reports compatibility with PSCI v1.1 since v1.5. Upstream ARM TF-A support for STM32MP was introduced with v1.6. It's thus safe to assume that the STM32MP barebox will never have to interact with a secure monitor implementing PSCI v0.1. Overwrite the psci device tree compatible to specify v0.2. This is the first version that implements PSCI_VERSION, which allows the barebox psci client driver selected in this commit to query the actual PSCI version and fix it up into the device tree. This fixes an issue where resetting via PSCI fails in Linux because the upstream device tree compatible: reboot: Restarting system Reboot failed -- System halted Reported-by: Michael Olbrich <mol@pengutronix.de> Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | ARM: dts: imx25-karo-tx25: include Linux dts instead of duplicating itUwe Kleine-König2019-09-122-96/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reduces duplicated information and benefits automatically from some changes that were done in Linux since the board was last touched in barebox. Also the intended differences are more obvious this way. To not include dts/src/arm/imx25.dtsi twice (which undoes some intended changes) it is necessary to drop the respective include from arch/arm/dts/imx25.dtsi. This is not a problem as tx25 is its only consumer. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | ARM: dts: drop skeleton.dtsiUwe Kleine-König2019-09-128-20/+27
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the Linux dts files skeleton.dtsi was dropped (in commit abe60a3a7afb ("ARM: dts: Kill off skeleton{64}.dtsi") for v5.1-rc1). At least one reason for this also applies for barebox: memory nodes are supposed to have a unit address and so adding a memory node without address isn't sensible. There are only four dtsi files that use skeleton.dtsi. Add some of the nodes and properties defined in skeleton.dtsi to its includers. I dropped adding empty alias nodes as neither barebox nor Linux depend on its presence. All consumers override reg in the memory node, so add the device_type property there. The remaining properties are added unchanged. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ATSAMA5D27-SOM1-EK1 is Microchip's evaluation kit for the SAMA5D2 System in Packages (SiPs). The ATSAMA5D27C-D1G-CU SIP embeds 128 MB of DDR2 DRAM and the SoM has a PMIC, QSPI flash and a 100Mbps PHY. barebox already supports the sama5d2 clocks, GPIO/Pinctrl, QSPI controller and Ethernet MAC. Most notable omission is the sama5d2 variant of the SDHCI, which differs from the MCI used by previous AT91 boards, but we kernel boot over the network works, so lets add the board now and have the SDHCI follow later.
