Add documentation for pcm parameters. Signed-off-by: Abhishek Pandit-Subedi <abhishekpandit@chromium.org> --- Changes in v4: - Fix incorrect function name in hci_bcm Changes in v3: - Change disallow baudrate setting to return -EBUSY if called before ready. bcm_proto is no longer modified and is back to being const. - Changed btbcm_set_pcm_params to btbcm_set_pcm_int_params - Changed brcm,sco-routing to brcm,bt-sco-routing Changes in v2: - Use match data to disallow baudrate setting - Parse pcm parameters by name instead of as a byte string - Fix prefix for dt-bindings commit .../devicetree/bindings/net/broadcom-bluetooth.txt | 11 +++++++++++ 1 file changed, 11 insertions(+)
