rk3399-gru chromebooks have a regulator chains where one named regulator supplies multiple regulators pp900-usb pp900_pcie that supply the named peripherals. The dtsi used somewhat creative structure to describe that in creating the base node 3 times with different phandles and describing the EC dependency in a comment. This didn't register in the recent regulator-node renaming, as the additional nodes were empty, so adapt the missing node names for now.

2025-02-03arm64: dts: rockchip: Disable DMA for uart5 on px30-ringneckLukasz Czechowski
UART controllers without flow control seem to behave unstable in case DMA is enabled. The issues were indicated in the message: https://lore.kernel.org/linux-arm-kernel/CAMdYzYpXtMocCtCpZLU_xuWmOp2Ja_v0Aj0e6YFNRA-yV7u14g@mail.gmail.com/ In case of PX30-uQ7 Ringneck SoM, it was noticed that after couple of hours of UART communication, the CPU stall was occurring, leading to the system becoming unresponsive. After disabling the DMA, extensive UART communication tests for up to two weeks were performed, and no issues were further observed. The flow control pins for uart5 are not available on PX30-uQ7 Ringneck, as configured by pinctrl-0, so the DMA nodes were removed on SoM dtsi.

2025-02-03arm64: dts: rockchip: Move uart5 pin configuration to px30 ringneck SoMLukasz Czechowski
In the PX30-uQ7 (Ringneck) SoM, the hardware CTS and RTS pins for uart5 cannot be used for the UART CTS/RTS, because they are already allocated for different purposes. CTS pin is routed to SUS_S3# signal, while RTS pin is used internally and is not available on Q7 connector.

Commit c8c68c38b56f ("cpufreq: amd-pstate: initialize core precision boost state") sets per-policy boost flag to false when boost fail. However, this boost flag will be set to reverse value in store_local_boost() and cpufreq_boost_trigger_state() in cpufreq.c. This will cause the per-policy boost flag set to true when fail to set boost. Remove the extra assignment in amd_pstate_set_boost() and keep all operations on per-policy boost flag outside of set_boost() to fix this problem.

My measurements performed with iperf3 and an Edimax EW-7811Un (VID: 7392, PID: 7811) showed a maximum TX rate of about 4 Mbits/sec compared to the ~24 Mbits/sec measured with the rtl8192cu driver.

2025-02-03wifi: rtw89: regd: refactor init/setup flow and prototypeZong-Zhe Yang
The regulatory and wiphy setup should be done in rtw89_regd_setup(). And, what rtw89_regd_init() should do is to initialize target regulatory domain (regd), if and only if one is programmed in efuse. Since HW is registered after rtw89_regd_setup() and before rtw89_regd_init(), do not fill fields of regulatory in rtw89_regd_init(). So, move the regulatory->reg_6ghz_power assignment into rtw89_regd_setup(). Besides, rtw89_regd_notifier is assigned in rtw89_regd_setup() instead of rtw89_regd_init(). To reduce confusion, stop passing rtw89_regd_notifier to rtw89_regd_init(). And, rename rtw89_regd_init() to rtw89_regd_init_hint().

Regd table is a table that we use to describe how to map Realtek RF TX power settings on different countries. Originally, a common regd table for all chips is implemented in driver. However, in order to work on all chips, the common regd table might have some trade-off. So now, there are also an individual regd table for some chips. And, we support loading it from FW element.

2025-02-03wifi: rtw89: phy: disable CFO track when two PHY are working simultaneouslyPing-Ke Shih
To have good performance, adjust hardware XTAL to track CFO (carrier frequency offset). However, there is only one hardware XTAL, so it is not possible to track on two PHY simultaneously. It also can't track on single one PHY when two PHY are working, because the adjustment of XTAL will affect all PHY. Thus, disable CFO track for this case.

2025-02-02sched_ext: Fix incorrect time delta calculation in time_delta()Changwoo Min
When (s64)(after - before) > 0, the code returns the result of (s64)(after - before) > 0 while the intended result should be (s64)(after - before). That happens because the middle operand of the ternary operator was omitted incorrectly, returning the result of (s64)(after - before) > 0. Thus, add the middle operand -- (s64)(after - before) -- to return the correct time calculation.
