2020-06-18arm64: dts: imx8mn-ddr4-evk: correct ldo1/ldo2 voltage rangeRobin Gong
Correct ldo1 voltage range from wrong high group(3.0V~3.3V) to low group (1.6V~1.9V) because the ldo1 should be 1.8V. Actually, two voltage groups have been supported at bd718x7-regulator driver, hence, just corrrect the voltage range to 1.6V~3.3V. For ldo2@0.8V, correct voltage range too. Otherwise, ldo1 would be kept @3.0V and ldo2@0.9V which violate i.mx8mn datasheet as the below warning log in kernel: [ 0.995524] LDO1: Bringing 1800000uV into 3000000-3000000uV [ 0.999196] LDO2: Bringing 800000uV into 900000-900000uV Fixes: 3e44dd09736d ("arm64: dts: imx8mn-ddr4-evk: Add rohm,bd71847 PMIC support") Cc: stable@vger.kernel.org Signed-off-by: Robin Gong <yibin.gong@nxp.com> Reviewed-by: Dong Aisheng <aisheng.dong@nxp.com> Reviewed-by: Fabio Estevam <festevam@gmail.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2020-04-14arm64: dts: imx8mn-ddr4-evk: Add secondary cpus supplyAnson Huang
Each cpu-core is supposed to list its supply separately, add supply for secondary cpus. Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2019-12-09arm64: dts: imx8m: Add ddr controller nodesLeonard Crestez
This is used by the imx-ddrc devfreq driver to implement dynamic frequency scaling of DRAM. Support for proactive scaling via interconnect will come later. The high-performance bus masters which need that (display, vpu, gpu) are mostly not yet enabled in upstream anyway.

2019-10-28arm64: dts: imx8mn: Create EVK dtsi file for common useAnson Huang
i.MX8MN has different EVK boards to support different DDR types, the ONLY differences are DDR chips and PMIC, so most of the devices can be shared between these EVK boards, create a EVK dtsi file for common use.

2019-10-28arm64: dts: imx8mn: Move usdhc clocks assignment to board DTAnson Huang
usdhc's clock rate is different according to different devices connected, so clock rate assignment should be placed in board DT according to different devices connected on each usdhc port.
