2023-06-05clk: renesas: mstp: Convert to readl_poll_timeout_atomic()Geert Uytterhoeven
Use readl_poll_timeout_atomic() instead of open-coding the same operation. As typically no retries are needed, 10 µs is a suitable timeout value.

2023-06-05clk: nuvoton: Add clock driver for ma35d1 clock controllerJacky Huang
The clock controller generates clocks for the whole chip, including system clocks and all peripheral clocks. This driver support ma35d1 clock gating, divider, and individual PLL configuration. There are 6 PLLs in ma35d1 SoC: - CA-PLL for the two Cortex-A35 CPU clock - SYS-PLL for system bus, which comes from the companion MCU and cannot be programmed by clock controller. - DDR-PLL for DDR - EPLL for GMAC and GFX, Display, and VDEC IPs. - VPLL for video output pixel clock - APLL for SDHC, I2S audio, and other IPs. CA-PLL has only one operation mode. DDR-PLL, EPLL, VPLL, and APLL are advanced PLLs which have 3 operation modes: integer mode, fraction mode, and spread specturm mode.

Introduce PLL clock controller for Amlogic A1 SoC family. The clock unit is an APB slave module that is designed for generating all of the internal and system clocks. The SoC uses an external 24MHz crystal; there are 4 internal PLLs: SYS_PLL/HIFI_PLL/USB_PLL/(FIXPLL), these PLLs generate 27 clock sources.

2023-05-30clk: meson: introduce new pll power-on sequence for A1 SoC familyDmitry Rokosov
Modern meson PLL IPs are a little bit different from early known PLLs. The main difference is located in the init/enable/disable sequences; the rate logic is the same. In A1 PLL, the PLL enable sequence is different, so add new optional pll reg bits and use the new power-on sequence to enable the PLL: 1. enable the pll, delay for 10us 2. enable the pll self-adaption current module, delay for 40us 3. enable the lock detect module Signed-off-by: Jian Hu <jian.hu@amlogic.com> Acked-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Dmitry Rokosov <ddrokosov@sberdevices.ru> Link: https://lore.kernel.org/r/20230523135351.19133-3-ddrokosov@sberdevices.ru Signed-off-by: Jerome Brunet <jbrunet@baylibre.com>

2023-05-24clk: qcom: smd-rpm: conditionally enable scaling before doing handoverLuca Weiss
On older platforms like msm8226, msm8974 and msm8916 the driver in the downstream kernel enables scaling first before doing the handover of the clocks. While this normally doesn't seem to cause noticeable problems, on apq8026-asus-sparrow this causes the device to immediately reboot, perhaps due to older rpm firmware that becomes unhappy. On newer platforms the order has swapped and enabling scaling is done after the handover, so let's introduce this behavior only conditionally for msm8226 and msm8974 for now.

2023-05-18clk: sunxi-ng: a64: force select PLL_MIPI in TCON0 muxRoman Beranek
TCON0's source clock can be fed from either PLL_MIPI, or PLL_VIDEO0(2X), however MIPI DSI output only seems to work when PLL_MIPI is selected and thus the choice must be hardcoded in. Currently, this driver can't propagate rate change from N-K-M clocks (such as PLL_MIPI) upwards. This prevents PLL_VIDEO0 from participating in setting of the TCON0 data clock rate, limiting the precision with which a target pixel clock can be matched. For outputs with fixed TCON0 divider, that is DSI and LVDS, the dotclock can deviate up to 8% off target.

2023-05-18clk: imx: imx6sx: Remove CLK_SET_RATE_PARENT from the LDB clocksFabio Estevam
On the i.MX6SX, it is common to use the LDB and LCDIF with the same parent clock, such as the IMX6SX_CLK_PLL5_VIDEO_DIV, for example. Due to the CLK_SET_RATE_PARENT flag, the LDB clock would try to set the clock parent rate, which can mess with the required clock rate calculated from the eLCDIF driver. To prevent this problem, remove the CLK_SET_RATE_PARENT flag from the LDB clocks, so that a correct clock relationship can be achieved.
