In prevision to add new UAPI for hwtstamp we will be limited to the struct ethtool_ts_info that is currently passed in fixed binary format through the ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h. The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO. Acked-by:

Kory Maincent authored
Change the API to select MAC default time stamping instead of the PHY. Indeed the PHY is closer to the wire therefore theoretically it has less delay than the MAC timestamping but the reality is different. Due to lower time stamping clock frequency, latency in the MDIO bus and no PHC hardware synchronization between different PHY, the PHY PTP is often less precise than the MAC. The exception is for PHY designed specially for PTP case but these devices are not very widespread. For not breaking the compatibility default_timestamp flag has been introduced in phy_device that is set by the phy driver to know we are using the old API behavior. Reviewed-by:

In preparation for using the power sequencing subsystem on sm8650 boards and X13s laptop let's make pwrseq the default for wcn7850 and wcn6855. Both these models require an enable GPIO so we can safely assume that if the property is not there, then we should try to get the power sequencer. Due to how the pwrseq lookup works - checking the provider at run-time - we cannot really do it the other way around as we'd get stuck forever on -EPROBE_DEFER. If the relevant OF node does have the 'enable-gpios' property, we fallback to the existing code for backward compatibility with older DTs. Signed-off-by:

In preparation for unduplicating the hci_uart registration code, schedule a devres action for disabling the SUSCLK rather than doing it manually. We cannot really use devm_clk_get_enabled() as we also set the rate before enabling the clock. While this should in theory work, I don't want to risk breaking existing users. One solution for the future is to add devm_clk_get_enabled_with_rate() to the clock framework. Signed-off-by:

This patch implements functions for ISO data send and receive in btusb driver for MediaTek's controller. MediaTek defines a specific interrupt endpoint for ISO data transmissin because the characteristics of interrupt endpoint are similar to the application of ISO data which can support guaranteed transmissin bandwidth, enough maximum data length and error checking mechanism. Driver sets up ISO interface and endpoints in btusb_mtk_setup and clears the setup in btusb_mtk_shutdown. These flow can't move to btmtk.c due to btusb_driver is only defined in btusb.c when claiming/relaesing interface. ISO packet anchor stops when driver suspending and resubmit interrupt urb for ISO data when driver resuming. Signed-off-by:
