The Lenovo Thinkpad X13s has a WCN6855 Bluetooth controller on uart2, add this. Signed-off-by: Steev Klimaszewski <steev@kali.org> --- Changes since v5: * Update patch subject * Specify initial mode (via guess) for vreg_s1c * Drop uart17 definition * Rename bt_en to bt_default because configuring more than one pin * Correct (maybe) bias configurations * Correct cts gpio * Split rts-tx into two nodes * Drop incorrect link in the commit message Changes since v4: * Address Konrad's review comments. Changes since v3: * Add vreg_s1c * Add regulators and not dead code * Fix commit message changelog Changes since v2: * Remove dead code and add TODO comment * Make dtbs_check happy with the pin definitions .../qcom/sc8280xp-lenovo-thinkpad-x13s.dts | 80 +++++++++++++++++++ 1 file changed, 80 insertions(+)
