This includes the newly added Nextthing GR8 platform, which is derived from sun5i/A13. - Some integrator (arm32) changes rely on clk driver changes. - A single patch for lpc32xx has no such dependency but wasn't added until just before the merge window" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (99 commits) ARM: dts: lpc32xx: add device node for IRAM on-chip memory ARM: dts: sun8i: Add accelerometer to polaroid-mid2407pxe03 ARM: dts: sun8i: enable UART1 for iNet D978 Rev2 board ARM: dts: sun8i: add pinmux for UART1 at PG dts: sun8i-h3: add I2C0-2 peripherals to H3 SOC dts: sun8i-h3: add pinmux definitions for I2C0-2 dts: sun8i-h3: associate exposed UARTs on Orange Pi Boards dts: sun8i-h3: split off RTS/CTS for UART1 in seperate pinmux dts: sun8i-h3: add pinmux definitions for UART2-3 ARM: dts: sun9i: a80-optimus: Disable EHCI1 ARM: dts: sun9i: cubieboard4: Add AXP806 PMIC device node and regulators ARM: dts: sun9i: a80-optimus: Add AXP806 PMIC device node and regulators ARM: dts: sun9i: cubieboard4: Declare AXP809 SW regulator as unused ARM: dts: sun9i: a80-optimus: Declare AXP809 SW regulator as unused ARM: dts: sun8i: Add touchscreen node for sun8i-a33-ga10h ARM: dts: sun8i: Add touchscreen node for sun8i-a23-polaroid-mid2809pxe04 ARM: dts: sun8i: Add touchscreen node for sun8i-a23-polaroid-mid2407pxe03 ARM: dts: sun8i: Add touchscreen node for sun8i-a23-inet86dz ARM: dts: sun8i: Add touchscreen node for sun8i-a23-gt90h ARM64: dts: meson-gxbb-vega-s95: Enable USB Nodes ...
