Pull ARM SoC driver updates from Arnd Bergmann: "This contains driver changes that are tightly connected to SoC specific code. Aside from smaller cleanups and bug fixes, here is a list of the notable changes. New device drivers: - The Turris Mox router has a new "moxtet" bus driver for its on-board pluggable extension bus. The same platform also gains a firmware driver. - The Samsung Exynos family gains a new Chipid driver exporting using the soc device sysfs interface - A similar socinfo driver for Qualcomm Snapdragon chips. - A firmware driver for the NXP i.MX DSP IPC protocol using shared memory and a mailbox Other changes: - The i.MX reset controller driver now supports the NXP i.MX8MM chip - Amlogic SoC specific drivers gain support for the S905X3 and A311D chips - A rework of the TI Davinci framebuffer driver to allow important cleanups in the platform code - A couple of device drivers for removed ARM SoC platforms are removed. Most of the removals were picked up by other maintainers, this contains whatever was left" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (123 commits) bus: uniphier-system-bus: use devm_platform_ioremap_resource() soc: ti: ti_sci_pm_domains: Add support for exclusive and shared access dt-bindings: ti_sci_pm_domains: Add support for exclusive and shared access firmware: ti_sci: Allow for device shared and exclusive requests bus: imx-weim: remove incorrect __init annotations fbdev: remove w90x900/nuc900 platform drivers spi: remove w90x900 driver net: remove w90p910-ether driver net: remove ks8695 driver firmware: turris-mox-rwtm: Add sysfs documentation firmware: Add Turris Mox rWTM firmware driver dt-bindings: firmware: Document cznic,turris-mox-rwtm binding bus: moxtet: fix unsigned comparison to less than zero bus: moxtet: remove set but not used variable 'dummy' ARM: scoop: Use the right include dt-bindings: power: add Amlogic Everything-Else power domains bindings soc: amlogic: Add support for Everything-Else power domains controller fbdev: da8xx: use resource management for dma fbdev: da8xx-fb: drop a redundant if fbdev: da8xx-fb: use devm_platform_ioremap_resource() ...

+Turris Mox rWTM firmware driver
+
+Required properties:
+ - compatible : Should be "cznic,turris-mox-rwtm"
+ - mboxes : Must contain a reference to associated mailbox
+
+This device tree node should be used on Turris Mox, or potentially another A3700
+compatible device running the Mox's rWTM firmware in the secure processor (for
+example it is possible to flash this firmware into EspressoBin).
+
+Example:
+
+ firmware {
+ turris-mox-rwtm {
+ compatible = "cznic,turris-mox-rwtm";
+ mboxes = <&rwtm 0>;
+ status = "okay";
+ };
+ };
