Subject: [PATCH] arm64: dts: ls1028a: Update the clock providers for the Mali
|
||
|
|
DP500
|
||
|
|
|
||
|
|
In order to maximise performance of the LCD Controller's 64-bit AXI
|
||
|
|
bus, for any give speed bin of the device, the AXI master interface
|
||
|
|
clock(ACLK) clock can be up to CPU_frequency/2, which is already
|
||
|
|
capable of optimal performance. In general, ACLK is always expected
|
||
|
|
to be equal to CPU_frequency/2. APB slave interface clock(PCLK) and
|
||
|
|
Main processing clock(PCLK) both are tied to the same clock as ACLK.
|
||
|
|
|
||
|
|
This change followed the LS1028A Architecture Specification Manual.
