[PATCH AUTOSEL 6.13 01/32] selftests/bpf: Adjust data size to have ETH_HLEN

by Sasha Levin

From: Shigeru Yoshida <syoshida(a)redhat.com> [ Upstream commit c7f2188d68c114095660a950b7e880a1e5a71c8f ] The function bpf_test_init() now returns an error if user_size (.data_size_in) is less than ETH_HLEN, causing the tests to fail. Adjust the data size to ensure it meets the requirement of ETH_HLEN.

[PATCH AUTOSEL 6.6 01/17] HID: intel-ish-hid: fix the length of MNG_SYNC_FW_CLOCK in doorbell

by Sasha Levin

From: Zhang Lixu <lixu.zhang(a)intel.com> [ Upstream commit 4b54ae69197b9f416baa0fceadff7e89075f8454 ] The timestamps in the Firmware log and HID sensor samples are incorrect. They show 1970-01-01 because the current IPC driver only uses the first 8 bytes of bootup time when synchronizing time with the firmware. The firmware converts the bootup time to UTC time, which results in the display of 1970-01-01. In write_ipc_from_queue(), when sending the MNG_SYNC_FW_CLOCK message, the clock is updated according to the definition of ipc_time_update_msg. However, in _ish_sync_fw_clock(), the message length is specified as the size of uint64_t when building the doorbell. As a result, the firmware only receives the first 8 bytes of struct ipc_time_update_msg. This patch corrects the length in the doorbell to ensure the entire ipc_time_update_msg is sent, fixing the timestamp issue.

[PATCH 0/2] clk: qcom: gdsc: Update retain_ff sequence and timeout for GDSC

The retain_ff bit should be updated for a GDSC when it is under SW control and ON. The current sequence needs to be fixed as the GDSC needs to update retention and is moved to HW control which does not guarantee the GDSC to be in enabled state. During the GDSC FSM state, the GDSC hardware waits for an ACK and the timeout for the ACK is 2000us as per design requirements.
