commit 54fb3fe0f211d4729a2551cf9497bd612189af9d upstream.

This reverts commit 193d00a2b35ee3353813b4006a18131122087205.

Commit 951d48855d86 ("of: Make of_dma_get_range() work on bus nodes")
reworked the logic such that of_dma_get_range() works correctly
starting from a bus node containing "dma-ranges".

Since on Juno we don't have a SoC level bus node and "dma-ranges" is
present only in the root node, we get the following error:

OF: translation of DMA address(0) to CPU address failed node(/sram@2e000000)
OF: translation of DMA address(0) to CPU address failed node(/uart@7ff80000)
...
OF: translation of DMA address(0) to CPU address failed node(/mhu@2b1f0000)
OF: translation of DMA address(0) to CPU address failed node(/iommu@2b600000)
OF: translation of DMA address(0) to CPU address failed node(/iommu@2b600000)
OF: translation of DMA address(0) to CPU address failed node(/iommu@2b600000)

So let's fix it by dropping the "dma-ranges" property for now. This
should be fine since it doesn't represent any kind of device-visible
restriction; it was only there for completeness, and we've since given
in to the assumption that missing "dma-ranges" implies a 1:1 mapping
anyway.

We can add it later with a proper SoC bus node and moving all the
devices that belong there along with the "dma-ranges" if required.

Turns out when introducing the eMMC version the gpmi node required for
NAND flash support got enabled exclusively on Colibri iMX7D 512MB.

commit 4a132f60808ae3a751e107a373f8572012352d3c upstream.

The EDIMM STARTER KIT i.Core 1.5 MIPI Evaluation is based on
the 1.5 version of the i.Core MX6 cpu module. The 1.5 version
differs from the original one for a few details, including the
ethernet PHY interface clock provider.

With this commit, the ethernet interface works properly:
SMSC LAN8710/LAN8720 2188000.ethernet-1:00: attached PHY driver

While before using the 1.5 version, ethernet failed to startup
do to un-clocked PHY interface:
fec 2188000.ethernet eth0: could not attach to PHY

Similar fix has merged for i.Core MX6Q but missed to update for DL.

commit 37c045d25e90038682b845de0a1db43c8301694d upstream.

The 1.5 version of Engicam's i.Core MX6 CPU module features a different clock
provider for the ethernet's PHY interface. Adjust the FEC ptp clock to
reference CLK_ENET_REF clock source, and set SION bit of
MX6QDL_PAD_GPIO_16__ENET_REF_CLK to adjust the input path of that pin.

The newly introduced imx6ql-icore-1.5.dtsi allows to collect in a single
place differences between version '1.0' and '1.5' of the module.

commit ab6a2114433a3b5b555983dcb9b752a85255f04b upstream.

set_cache_qos_cfg() is leaking memory when the given level is not
RDT_RESOURCE_L3 or RDT_RESOURCE_L2. At the moment, this function is
called with only valid levels but move the allocation after the valid
level checks in order to make it more robust and future proof.

commit 4911ee401b7ceff8f38e0ac597cbf503d71e690c upstream.

The EFI mixed mode entry code goes through the ordinary startup_32()
routine before jumping into the kernel's EFI boot code in 64-bit
mode. The 32-bit startup code must be entered with paging disabled,
but this is not documented as a requirement for the EFI handover
protocol, and so we should disable paging explicitly when entering
the kernel from 32-bit EFI firmware.

commit a006483b2f97af685f0e60f3a547c9ad4c9b9e94 upstream.

If the SME and SEV features are present via CPUID, but memory encryption
support is not enabled (MSR 0xC001_0010[23]), the feature flags are cleared
using clear_cpu_cap(). However, if get_cpu_cap() is later called, these
feature flags will be reset back to present, which is not desired.

Change from using clear_cpu_cap() to setup_clear_cpu_cap() so that the
clearing of the flags is maintained.
