[PATCH] dt-bindings: cache: qcom,llcc: correct QDU1000 reg entries

[PATCH] dt-bindings: cache: qcom,llcc: correct QDU1000 reg entries

[Krzysztof Kozlowski]

Qualcomm QDU1000 DTSI comes with one LLCC0 base address as pointed by
dtbs_check:

  qdu1000-idp.dtb: system-cache-controller@19200000: reg-names:2: 'llcc2_base' was expected

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

---

Recent LLCC patches were not tested on QDU1000 thus the LLCC is there
broken.  This patch at least tries to bring some sense according to
DTSI, but I have no clue what is here correct: driver, DTS or bindings.

I'm assuming given your employer, this ack means that there is no
llcc2_base on the qdu1000.

Looks like i saw downstream usage and said LLCC has only one
instance for qdu1000, it looks refactor happened during the
same where each bank need to separately denoted in device tree.
Change was fine a/c to its usage in device tree.
Not an excuse, that is an ignorance from my side while acking
the change.

qdu1000 has 8 banks from llcc0-7 that need to corrected both
in its device tree and in the binding.

@komal will be sending patch for this.
