commit 756534f7cf53f35e9e098c15a6e341f27b5888d9
category: bugfix

--------------------------------

[ Upstream commit e68be7b3 ]

make dtbs_check gives the following errors:

ref-clock-frequency: size (9) error for type uint32
tcxo-clock-frequency: size (9) error for type uint32

Fix it by passing the frequencies inside < > as documented in
Documentation/devicetree/bindings/net/wireless/ti,wlcore.yaml.
