Subject: soc: qcom: ipq806x: Increase Atomic Coherent Pool size
|
|
|
|
Linux 3.14, by default allocates a 256K Atomic Coherent Pool.
|
|
However, Linux 3.4 seems to have allocated ~1.8M for the same.
|
|
256K doesn't seem to be enough for the WiFi driver. Hence,
|
|
setting the size to be similar to 3.4.
