I have bought DWA-552 from Newegg.  It's revision A2.  The chip is
marked as AR9223.

lspci should that it's exactly the same device as yours:

02:01.0 Network controller [0280]: Atheros Communications Inc. AR922X
Wireless Network Adapter [168c:0029] (rev 01)
        Subsystem: D-Link System Inc Device [1186:3a7a]
        Flags: bus master, 66MHz, medium devsel, latency 168, IRQ 18
        Memory at fe3f0000 (32-bit, non-prefetchable) [size=64K]
        Capabilities: [44] Power Management version 2
        Kernel driver in use: ath9k
        Kernel modules: ath9k

ath9h identifies the device as:
phy3: Atheros AR9280 Rev:2 mem=0xffffc90010260000, irq=18

I cannot reproduce your problem.  Everything is working just fine.

I checked what is read from the register 0x7000.  It's always 0x00000000
or 0x00000002 and never 0xffffffff.  I assume your card has some
hardware issue.

But the way, revision A2 doesn't just have another chip.  It looks very
different from the revision A1.  It's smaller and comes with an
additional low-profile bracket.  Antennas are closer to each other.  The
picture on the box shows it clearly.  D-Link must be getting really low
on model numbers if they are reusing the same number for a substantially
different product.
