4 Subject: [PATCH 006/182] clocksource: qcom: split building of legacy vs
5 multiplatform support
6
7 The majority of the clocksource code for the Qualcomm platform is shared
8 between newer (multiplatform) and older platforms. However there is a bit
9 of code that isn't, so only build it for the appropriate config.
