Subject: soc: qcom: llcc-qcom: Add support for Eliza
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=0a4d53ae2cb68cbfe3c69e14d8cfc0acc7c37bda;p=thirdparty%2Fkernel%2Flinux.git

soc: qcom: llcc-qcom: Add support for Eliza

Eliza uses a 4-region LLCC register layout made up of two per-bank base
register regions together with the broadcast OR and AND regions.

So add this SoC specific configuration and its compatible string.
