The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").
These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:
"Node /memory has a reg or ranges property, but no unit name"
The disassembled DTB are almost the same besides an empty chosen
node being removed and nodes reordered, so it shouldn't have
functional changes.
Since no am4372 based board had a memory node defined, a dummy node
is added so the compiled DTB memory node is the same than before.

But these boards don't have a memory node defined, so removing the
skeleton.dtsi inclusion from omap3.dtsi will cause a change in the
compiled DTB. Add a dummy memory node so the compiled DTB doesn't
change if the skeleton.dtsi is removed from omap3.dtsi.
Eventually the correct starting addresses and sizes should be used
but I didn't find that information.

Current clocks tree definition for CPSW/CPTS doesn't
correspond TRM for dra7/am57 SoCs.
CPTS: has to be sourced from gmac_rft_clk_mux clock
CPSW: DPLL_GMAC -> CLKOUT_M2 -> GMAC_250M_CLK -> 1/2 ->
-> GMAC_MAIN_CLK (125 MHZ)
Hence, correct clock tree for GMAC_MAIN_CLK and use proper
clock for CPTS. This also require updating of CPTS clock
multiplier.

This commit fixes the clock data inside the DRA7xx clocks device tree
structure for the gmac_gmii_ref_clk_div clock. This clock is actually
the GMAC_MAIN_CLK and has nothing to do with the register at address
0x4a0093d0. If CLKSEL_REF bit 24 inside of CM_GMAC_GMAC_CLKCTRL, is
set to 1 in order to use the GMAC_RMII_CLK instead of the
GMAC_RMII_HS_CLK, the kernel generates a clock divider warning:
WARNING: CPU: 0 PID: 0 at drivers/clk/clk-divider.c:129 clk_divider_recalc_rate+0xa8/0xe0()
gmac_gmii_ref_clk_div: Zero divisor and CLK_DIVIDER_ALLOW_ZERO not set
By properly configuring the gmac_gmii_ref_clk_div (GMAC_MAIN_CLK) to
have the parent of dpll_gmac_m2_ck always divided by 2 the warning is
resolved and the clock tree is fixed up.
Additionally, a new clock called rmii_50mhz_clk_mux is defined that
does utilize CM_GMAC_GMAC_CLKCTRL[24] CLKSEL_REF to configure the
source clock for the RMII_50MHZ_CLK.

Commit b8d368caa8 ("ARM: dts: omap3: overo: remove unneded unit names
in display nodes") removed the unit names for all Overo display nodes
that didn't have a reg property.
But the display in arch/arm/boot/dts/omap3-overo-common-lcd35.dtsi does
have a reg property so the correct fix was to make the unit name match
the value of the reg property, instead of removing it.

- correctly account for vDSO AUX entry in ARCH_DLINFO
- fix kallsyms with absolute expressions in linker script
- kill unnecessary symbol-based relocs in vmlinux
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: Fix copy-on-write referencing in HugeTLB
arm64: mm: avoid fdt_check_header() before the FDT is fully mapped
arm64: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO
arm64: relocatable: suppress R_AARCH64_ABS64 relocations in vmlinux
arm64: vmlinux.lds: make __rela_offset and __dynsym_offset ABSOLUTE
- Prevent the low-level assembly hibernate code on x86-64 from
referring to __PAGE_OFFSET directly as a symbol which doesn't work
when the kernel identity mapping base is randomized, in which case
__PAGE_OFFSET is a variable (Rafael Wysocki).
- Avoid selecting CPU_FREQ_STAT by default as the statistics are not
required for proper cpufreq operation (Borislav Petkov).
- Add Skylake-X and Broadwell-X IDs to the intel_pstate's list of
processors where out-of-band (OBB) control of P-states is possible
and if that is in use, intel_pstate should not attempt to manage
P-states (Srinivas Pandruvada).
- Drop some unnecessary checks from the wakeup IRQ handling code in
the PM core (Markus Elfring).
- Reduce the number operating performance point (OPP) lookups in
one of the OPP framework's helper functions (Jisheng Zhang).

Pull more power management updates from Rafael Wysocki:
"A few more fixes and cleanups in the x86-64 low-level hibernation
code, PM core, cpufreq (Kconfig and intel_pstate), and the operating
points framework.

- Prevent the low-level assembly hibernate code on x86-64 from
referring to __PAGE_OFFSET directly as a symbol which doesn't work
when the kernel identity mapping base is randomized, in which case
__PAGE_OFFSET is a variable (Rafael Wysocki).
