SMD edge contains subnodes representing devices related to the remote processor. With limietd number of remote processors, there is a limited set of such devices. List all of them in smd-edge bindings so schema can strictly check for subnodes. Additional benefit is requirement of "qcom,smd-channels" for such subnodes, because their schema cannot enforce it (few devices like APR or FastRPC can be part of either SMD or GLINK edge).

GLINK edge contains subnodes representing devices related to the remote processor. Each of such device (e.g. APR or FastRPC) must have a "qcom,glink-channels" property. However the APR or FastRPC device can be also part of other communication - SMD - thus their schema does not require "qcom,glink-channels". To make the GLINK edge bindings strict, require "qcom,glink-channels" for its children. Signed-off-by:

If the properties 'linux,initrd-start' and 'linux,initrd-end' of the chosen node populated from the bootloader, eg. U-Boot, are so that start > end, then the phys_initrd_size calculated from end - start is negative that subsequently gets converted to a high positive value for being unsigned long long. Then, the memory region with the (invalid) size is added to the bootmem and attempted being paged in paging_init() that results in the kernel fault. For example, on the FVP ARM64 system I'm running, the U-Boot populates the 'linux,initrd-start' with 8800_0000 and 'linux,initrd-end' with 0. The phys_initrd_size calculated is then ffff_ffff_7800_0000 (= 0 - 8800_0000 = -8800_0000 + ULLONG_MAX + 1). paging_init() then attempts to map the address 8800_0000 + ffff_ffff_7800_0000 and oops'es as below. It should be stressed, it is generally a fault of the bootloader's with the kernel relying on it, however we should not allow the bootloader's misconfiguration to lead to the kernel oops. Not only the kernel should be bullet proof against it but also finding the root cause of the paging fault spanning over the bootloader, DT, and kernel may happen is not so easy.

In commit 853a78a7 (dt-bindings: leds: Add LED_COLOR_ID definitions, Sun Jun 9 20:19:04 2019 +0200) the most basic color definitions where added. However, there's a little more very common LED colors. While the documentation states 'add what is missing', engineers tend to be lazy and will just use what currently exists. So this patch will take (a) list from online retailers [0], [1], [2] and use the common LED colors from there, this being reasonable as this is what is currently available to purchase. Note, that LIME seems to be the modern take to 'Yellow-green' or 'Yellowish-green' from some older datasheets.

For K3 devices the clock fed into the RNG module is shared with the rest of the Crypto module, it is not dedicated to the RNG module and cannot be controlled by the RNG driver. The driver does not require this clock to always be defined and the DT binding should not force it either. Remove this so we can start dropping out the clock properties as needed. Signed-off-by:

New pr_err(), a copy of preceeding pr_debug(), faciliates debugging. This change was inspired by a long lasting debugging of the octeon_irq_init_ciu() which fails completely silently and leaves the interrupt controller half-way configured which in turn had very non-obvious effects. Signed-off-by:

Convert Qualcomm FastRPC bindings to yaml format, so that we could validate dt-entries correctly and any future additions can go into yaml format. Use compute-cb@ subnodes instead of just cb@. Add qcom,glink-channels and qcom,smd-channels missing properties to make sure dtbs_check doesn't fail right off the bat. Correct the name of the parent node in the example from smd-edge to glink-edge. Since now the qcom,fastrpc bindings document is yaml, update the reference to it in qcom,glink-edge and also use $ref. Also update the MAINTAINERS file to point to the yaml version. Co-developed-by:

A GICv3 implementation without virtualization, such as the base QEMU virt machine (without -M virtualization=on), does not issue maintenance interrupts. Therefore its device-tree node does not need an 'interrupts' property. Currently, validating the QEMU virt device-tree throws a warning that 'interrupts' is missing. Make it optional. Signed-off-by:

Even PSCI v1.0 compliant implementations may support v0.1 clients (i.e. "arm,psci"). Relax the compatible schema such that an implementation can claim 1.0, 0.2, and 0.1 compatibility.
