| | | | | | | | | | | | | | | | | | | | | | The parent at this index is the secondary mux, which can connect not only to primary PLL/2 but also to XO. Rename the index to SMUX_INDEX to better reflect the parent.

* | clk: qcom: gcc-msm8909: Increase delay for USB PHY resetStephan Gerhold2022-09-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB PHY on MSM8909 works with the driver used on MSM8916 (phy-qcom-usb-hs.c). When turning the PHY on/off it is first reset using the standard reset controller API. On MSM8916 the reset is provided by the USB driver (ci_hdrc_msm_por_reset() in ci_hdrc_msm.c). While this seems to work on MSM8909 as well, the Qualcomm Linux sources suggest that the PHY should be reset using the GCC_USB2_HS_PHY_ONLY_BCR register instead. In general this is easy to set up in the device tree, thanks to the standard reset controller API. However, to conform to the specifications of the PHY the reset signal should be asserted for at least 10 us. This is handled correctly on MSM8916 in ci_hdrc_msm_por_reset(), but not within the GCC driver. Fix this by making use of the new "udelay" field of qcom_reset_map and set a delay of ~15 us between the assertion/deassertion of the USB PHY reset signal.

* | clk: qcom: reset: Allow specifying custom reset delayStephan Gerhold2022-09-132-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The amount of time required between asserting and deasserting the reset signal can vary depending on the involved hardware component. Sometimes 1 us might not be enough and a larger delay is necessary to conform to the specifications. Usually this is worked around in the consuming drivers, by replacing reset_control_reset() with a sequence of reset_control_assert(), waiting for a custom delay, followed by reset_control_deassert(). However, in some cases the driver making use of the reset is generic and can be used with different reset controllers. In this case the reset time requirement is better handled directly by the reset controller driver. Make this possible by adding an "udelay" field to the qcom_reset_map that allows setting a different reset delay (in microseconds).

* | clk: qcom: Add driver for MSM8909 GCCStephan Gerhold2022-09-133-0/+2740
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Global Clock Controller (GCC) in the MSM8909 SoC provides clocks, resets and power domains for the various hardware blocks in the SoC. Add a driver for it to make it possible to enable additional functionality for the SoC. Work on this driver was originally started independently by Dominik, I picked it up and added missing clocks/resets, as well as various cleanup to bring it into shape for mainline.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Snapdragon 670 adds and removes some clocks, adds new frequencies, and adds a new GPLL (Global Phase-Locked Loop) in reference to SDM845, while also removing some GDSCs. Despite these differences, there are many similarities with SDM670. Add data for SDM670 in the driver for SDM845 to reuse the most of the clock data. Advantages and disadvantages of this approach: + maintenance applies to both sdm670 and sdm845 by default + less duplicate code (clocks) means smaller distro/pre-built kernels with all drivers enabled - clocks for both SoC's must be compiled if the user wants clocks for one specific SoC (both or none) - additional testing needed for sdm845 devices Link: https://android.googlesource.com/kernel/msm/+/443bd8d6e2cf54698234c752e6de97b4b8a528bd%5E%21/#F10 Signed-off-by: Richard Acayan <mailingradian@gmail.com> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Signed-off-by: Bjorn Andersson <andersson@kernel.org> Link: https://lore.kernel.org/r/20220914013922.198778-4-mailingradian@gmail.com
