2017-10-14ARM: dts: imx7d: Invert legacy PCI irq mappingAndrey Smirnov1-4/+4
According to i.MX7D reference manual (Rev. 0.1, table 7-1, page 1221) legacy PCI interrupt mapping is as follows: - PCIE INT A is IRQ 122 - PCIE INT B is IRQ 123 - PCIE INT C is IRQ 124 - PCIE INT D is IRQ 125 Invert the mapping information in corresponding DT node to reflect that.

2016-08-17ARM: dts: imx7d: add clock-frequency to CPU nodesStefan Agner1-0/+2
Add clock-frequency property to CPU nodes. Avoids warnings like "/cpus/cpu@0 missing clock-frequency property". Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2016-08-17ARM: dts: imx7d: move CPU operating points to imx7d.dtsiStefan Agner1-0/+8
Only i.MX 7Dual SoC supports CPU frequencies of up to 1GHz. The i.MX 7Solo can run with up to 800MHz and does so without making use of DVFS usually. While the device tree clearly specified a too fast operating point for i.MX 7Solo, the kernel did not used it in practise so far because the CPUfreq driver does not get loaded on i.MX 7Solo devices (since the fsl,imx7s compatible string is not in the list of devices making use of the cpufreq-dt driver...).

2016-08-15ARM: dts: imx7d: move ARM platform peripherals inside soc nodeStefan Agner1-15/+17
Since we have a SoC level node we should make use of it and have all nodes which are within the SoC, inside that node. This also saves an extra interrupt-parent properties. While at it, also order the Coresight nodes according to register addresses. Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2016-06-28ARM: dts: imx7d: recreate imx7d.dtsi with i.MX 7Dual specificsStefan Agner1-0/+128
The i.MX 7Solo implements a subset of features available on i.MX 7Dual. Recreate imx7s.dtsi as the base device tree for i.MX 7Dual boards. The i.MX 7Dual's additional features over i.MX 7Solo are: - Second Cortex-A7 core - Second Gigabit Ethernet controller - EPD (Electronc Paper Display, not yet part of the device tree) - PCIe (not yet part of the device tree) - Additional USB2.0 OTG controller Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2016-06-28ARM: dts: imx7d: use imx7s.dtsi as base device treeStefan Agner1-1007/+0
The i.MX 7 series currently consists of two SoCs: i.MX 7Solo and 7Dual. The former has a subset of features of the latter, hence use imx7s.dtsi as the new base device tree. To keep diffstat nice, just move imx7d.dtsi to imx7s.dtsi temporarily and recreate imx7d.dtsi in a second commit.

Building with W=1 option leads to several warnings like: Warning (unit_address_vs_reg): Node /soc/aips-bus@02000000/anatop@020c8000/regulator-1p1@110 has a unit name, but no reg property Fix them by removing the unneeded unit-addresses.

2016-02-29ARM: dts: imx7d: add arch timerFrank Li1-0/+9
Since uboot v2016.01-rc2, which supported basic psci for i.mx7d. So imx7d's second core can be enabled by psci. Without arch timer, every timer event will be boardcasted to each core. arch timer has local timer irq for each core.
