Initially, this driver was designed to work with NWL driver as a
drm_bridge and it is required for this to work, otherwise it will defer.
When CONFIG_OF_DYNAMIC is used, the NWL bridge can be disabled by it's
remote endpoint, it that endpoint is an i2c capable device and it fails
to find a physical device on the expected i2c address.
If the NWL drm_bridge is disabled, since this driver it is required by

nothing, in order to not interfere with the other available devices

If RPMSG dma memory allocate from per-device mem pool by calling .dma_alloc_coherent(),
the size is bigger than 2M bytes and alignment with 2M (PMD_SIZE), then kernel dump by
calling .vmalloc_to_page().
Since per-device dma pool do vmap mappings by __ioremap(), __ioremap() might use
the hugepage mapping, which in turn will cause the vmalloc_page failed to return
the correct page due to the PTE not setup.
For exp, when reserve 8M bytes per-device dma mem pool, __ioremap() will use hugepage
mapping:
__ioremap
ioremap_page_range
ioremap_pud_range
ioremap_pmd_range
pmd_set_huge(pmd, phys_addr + addr, prot)
Commit:
029c54b09599 ("mm/vmalloc.c: huge-vmap: fail gracefully on unexpected huge
vmap mapping") ensure that vmalloc_to_page() does not go off into the weeds trying
to dereference huge PUDs or PMDs as table entries:
rpmsg_sg_init ->
vmalloc_to_page->
WARN_ON_ONCE(pmd_bad(*pmd));
In generally, .dma_alloc_coherent() allocate memory from CMA pool/DMA pool/atomic_pool,
or swiotlb slabs pool, the virt address mapping to physical address should be lineal,
so for the rpmsg scatterlist initialization can use pfn to find the page to avoid to
call .vmalloc_to_page().

MLK-21102 driver: thermal: fix the tmu out of range issue on imx8mm
Per design team's feadback, the 'V' bit is NOT very safe enough for
checking the validation of the temp value. So just check if the
temp value is in the sensor's valid measurment range.

MLK-21080-09 net: fec: Replace ARCH_MXC_ARM64 with HAVE_IMX_SC
Upstream rejected ARCH_MXC_ARM64 in favor of defining ARCH_MXC for
arm64.
Update the FEC driver to check for CONFIG_HAVE_IMX_SC around
SCFW-dependent code.

MLK-20958-2 imx8: Replace SC_R_LAST with SC_R_NONE in DTB
We are currently using SC_R_LAST as a marker for imx8 power domain tree
nodes without a resource attached. This value is compiled into dtb as
part of the linux build and used by uboot.
The SC_R_LAST constant changes frequently as SCFW resources are added
(by design) and every time we need to update linux and uboot headers
together or boot can fail.
Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE
defined to be 0xFFF0.
