From: Jens Glathe <redacted> To enable Bluetooth pwrseq appears to be required for the WCN7850. Add the nodes from QCP. Add uart14 for the BT interface. Signed-off-by: Jens Glathe <redacted> --- This patch adds the Bluetooth support for the WCN7850 card on this laptop. Since WCN7850 is supposed to need pwrseq, also added this from the QCP. This is also part of my tree [1] for the Yoga Slim 7X, although with an older definition for the pwrseq and regulators.
