[PATCH AUTOSEL 4.19 01/11] ARM: dts: sun4i-a10: fix cpu_alert temperature

[Sasha Levin]

From: Clément Péron <peron.clem@gmail.com>

[ Upstream commit dea252fa41cd8ce332d148444e4799235a8a03ec ]

When running dtbs_check thermal_zone warn about the
temperature declared.

thermal-zones: cpu-thermal:trips:cpu-alert0:temperature:0:0: 850000 is greater than the maximum of 200000

It's indeed wrong the real value is 85°C and not 850°C.

[PATCH AUTOSEL 4.19 04/11] of: Fix reserved-memory overlap detection

[Sasha Levin]

From: Vincent Whitchurch <vincent.whitchurch@axis.com>

[ Upstream commit ca05f33316559a04867295dd49f85aeedbfd6bfd ]

The reserved-memory overlap detection code fails to detect overlaps if
either of the regions starts at address 0x0.  The code explicitly checks
for and ignores such regions, apparently in order to ignore dynamically
allocated regions which have an address of 0x0 at this point.  These
dynamically allocated regions also have a size of 0x0 at this point, so
fix this by removing the check and sorting the dynamically allocated
regions ahead of any static regions at address 0x0.

For example, there are two overlaps in this case but they are not
currently reported:

	foo@0 {
	        reg = <0x0 0x2000>;
	};

	bar@0 {
	        reg = <0x0 0x1000>;
	};

	baz@1000 {
	        reg = <0x1000 0x1000>;
	};

	quux {
	        size = <0x1000>;
	};

but they are after this patch:

 OF: reserved mem: OVERLAP DETECTED!
 bar@0 (0x00000000--0x00001000) overlaps with foo@0 (0x00000000--0x00002000)
 OF: reserved mem: OVERLAP DETECTED!
 foo@0 (0x00000000--0x00002000) overlaps with baz@1000 (0x00001000--0x00002000)

Hi Sasha,

This needs also support in the dwc3-meson-g12a driver, you can drop it from backport.
