Merge tag 'arm-ffa-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/drivers Arm Firmware Framework for ARMv8-A(FFA) interface driver The Arm FFA specification describes a software architecture to leverages the virtualization extension to isolate software images provided by an ecosystem of vendors from each other and describes interfaces that standardize communication between the various software images including communication between images in the Secure world and Normal world. Any Hypervisor could use the FFA interfaces to enable communication between VMs it manages. The Hypervisor a.k.a Partition managers in FFA terminology can assign system resources(Memory regions, Devices, CPU cycles) to the partitions and manage isolation amongst them. This is the initial and minimal support for the FFA interface to enable communication between secure partitions and the normal world OS. * tag 'arm-ffa-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Add support for MEM_* interfaces firmware: arm_ffa: Setup in-kernel users of FFA partitions firmware: arm_ffa: Add support for SMCCC as transport to FFA driver firmware: arm_ffa: Add initial Arm FFA driver support firmware: arm_ffa: Add initial FFA bus support for device enumeration arm64: smccc: Add support for SMCCCv1.2 extended input/output registers Link: https://lore.kernel.org/r/20210601095838.GA838783@bogusSigned-off-by:

This adds support for the power domains founds on i.MX8MN. The Nano has fewer domains than the Mini, and the access to some of these domains is different than that of the Mini, the Mini power domains cannot be reused. Signed-off-by:

There is no point in having all these definitions at the SMC bus level, these are extremely tight to the NAND controller driver implementation, are not particularly generic, imply more boilerplate than needed, do not really follow the device model by receiving no argument and some of them are actually buggy. Let's get rid of these right now as there is no current user and keep this driver at a simple level: only the SMC bare initializations. The NAND controller driver which I am going to introduce will take care of redefining properly all these helpers and using them directly. Signed-off-by:

To be fully valid, the NAND controller node in the example should be named nand-controller instead of flash, should be at the address @0,0 instead of @e1000000 and should have a couple of: - #address-cells - #size-cells properties. The label is being renamed nfc0 as well which is more usual than nand_0. Signed-off-by:

These nodes are given as examples and are not described nor used anywhere else. There is also no hardware of my knowledge compatible with these yet. If we want to be backward compatible, then we should avoid partially describing nodes and their content while there are no users. Plus, the examples are wrong (the addresses should be updated) so let's drop them before converting this file to yaml (only the NAND node, which will be fixed in the example and described somewhere else is kept).

The driver defined several functions related to handling of frequency and voltage changes: - freq_post_notify_handling - freq_pre_notify_handling - volt_notify_handling All these are static, not used inside or outside of driver, and marked as unused with comment: "TODO: voltage notify handling should be hooked up to regulator framework as soon as the necessary support is available in mainline kernel. This function is un-used right now.". These have been added with commit a93de288 ("memory: emif: handle frequency and voltage change events") in 2012 and are unused since then. Additionally mentioned regulator and clock hooking did not happen since then. If it did not happen for nine years, let's assume it will not happen suddenly now. Remove all unused functions which also allows removal of "t_ck" static variable "t_ck" and "addressing" member of private structure. No functionality is lost. Signed-off-by:
