clk: si5351: allow PLLs to be adjusted without reset

2025-02-08T08:51:50+00:00

[ Upstream commit b2adbc9cea752539f6421e9d4642408f666c1251 ] Introduce a new PLL reset mode flag which controls whether or not to reset a PLL after adjusting its rate. The mode can be configured through platform data or device tree. Since commit 6dc669a22c77 ("clk: si5351: Add PLL soft reset"), the driver unconditionally resets a PLL whenever its rate is adjusted. The rationale was that a PLL reset was required to get three outputs working at the same time. Before this change, the driver never reset the PLLs. Commit b26ff127c52c ("clk: si5351: Apply PLL soft reset before enabling the outputs") subsequently introduced an option to reset the PLL when enabling a clock output that sourced it. Here, the rationale was that this is required to get a deterministic phase relationship between multiple output clocks. This clearly shows that it is useful to reset the PLLs in applications where multiple clock outputs are used. However, the Si5351 also allows for glitch-free rate adjustment of its PLLs if one avoids resetting the PLL. In our audio application where a single Si5351 clock output is used to supply a runtime adjustable bit clock, this unconditional PLL reset behaviour introduces unwanted glitches in the clock output. It would appear that the problem being solved in the former commit may be solved by using the optional device tree property introduced in the latter commit, obviating the need for an unconditional PLL reset after rate adjustment. But it's not OK to break the default behaviour of the driver, and it cannot be assumed that all device trees are using the property introduced in the latter commit. Hence, the new behaviour is made opt-in.

platform/x86: asus-wmi: add support for vivobook fan profiles

2024-12-14T18:59:35+00:00

[ Upstream commit bcbfcebda2cbc6a10a347d726e4a4f69e43a864e ] Add support for vivobook fan profiles wmi call on the ASUS VIVOBOOK to adjust power limits. These fan profiles have a different device id than the ROG series and different order. This reorders the existing modes. As part of keeping the patch clean the throttle_thermal_policy_available boolean stored in the driver struct is removed and throttle_thermal_policy_dev is used in place (as on init it is zeroed).
