| | | | | | | | | | | | | | | | | | | | Similar to msm8916, msm8939 has (at least) 6 "General Purpose" clocks that can be muxed to SoC pins. These clocks are: GP_CLK{0, 1} : GPIO_{31, 32} (Belongs to CAMSS according to Linux) GP_CLK_{1-3}{A, B} : GPIO_{49-51, 97, 12, 13} (Belongs to GCC itself) GP_MN : GPIO_110 (Doesn't seem to be described in gcc, ignored in this patch) Those clocks may be used as e.g. PWM sources for external peripherals. Add more frequencies to the table for those clocks so it's possible for arbitrary peripherals to make use of them.

* clk: qcom: krait-cc: handle secondary mux sourcing out of acpu_auxChristian Marangi2022-12-021-4/+4
| | | | | | | | | | | | | | | | | Some bootloader may leave the system in an even more undefined state with the secondary mux of L2 or other cores sourcing out of the acpu_aux parent. This results in the clk set to the PXO rate or a PLL8 rate. The current logic to reset the mux and set them to a defined state only handle if the mux are configured to source out of QSB. Change this and force a new and defined state if the current clk is lower than the aux rate. This way we can handle any wrong configuration where the mux is sourcing out of QSB (rate 225MHz, currently set to a virtual rate of 1), PXO rate (rate 25MHz) or PLL8 (needs to be configured to run at 384Mhz).

* clk: qcom: krait-cc: fix wrong parent order for secondary muxChristian Marangi2022-12-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The secondary mux parent order is swapped. This currently doesn't cause problems as the secondary mux is used for idle clk and as a safe clk source while reprogramming the hfpll. Each mux have 2 or more output but he always have a safe source to switch while reprogramming the connected pll. We use a clk notifier to switch to the correct parent before clk core can apply the correct rate. The parent to switch is hardcoded in the mux struct. For the secondary mux the safe source to use is the qsb parent as it's the only fixed clk as the acpus_aux is a pll that can source from pxo or from pll8. The hardcoded safe parent for the secondary mux is set to index 0 that in the secondary mux map is set to 2. But the index 0 is actually acpu_aux in the parent list. Fix the swapped parents to correctly handle idle frequency and output a sane clk_summary report.

* clk: qcom: reset: support resetting multiple bitsRobert Marko2022-12-022-2/+3
| | | | | | | | | | | | | | | | | | | | | | This patch adds the support for giving the complete bitmask in reset structure and reset operation will use this bitmask for all reset operations. Currently, reset structure only takes a single bit for each reset and then calculates the bitmask by using the BIT() macro. However, this is not sufficient anymore for newer SoC-s like IPQ8074, IPQ6018 and more, since their networking resets require multiple bits to be asserted in order to properly reset the HW block completely. So, in order to allow asserting multiple bits add "bitmask" field to qcom_reset_map, and then use that bitmask value if its populated in the driver, if its not populated, then we just default to existing behaviour and calculate the bitmask on the fly.

* clk: qcom: lpass-sc7280: Fix pm_runtime usageDouglas Anderson2022-12-021-34/+21

Specifically: 1. At the end of probe it called "put" twice. This is a no-no and will end us up with a negative usage count. Even worse than calling "put" twice, it never called "get" once. Thus after bootup it could be seen that the runtime usage of the devices managed by this driver was -2. 2. In some error cases it manually called pm_runtime_disable() even though it had previously used devm_add_action_or_reset() to set this up to be called automatically. This meant that in these error cases we'd double-call pm_runtime_disable(). 3. It forgot to call undo pm_runtime_use_autosuspend(), which can sometimes have subtle problems (and the docs specifically mention that you need to undo this function). Overall the above seriously calls into question how this driver is working. It seems like a combination of "it doesn't", "by luck", and "because of the weirdness of runtime_pm". Specifically I put a printout to the serial console every time the runtime suspend/resume was called for the two devices created by this driver (I wrapped the pm_clk calls). When I had serial console enabled, I found that the calls got resumed at bootup (when the clk core probed and before our double-put) and then never touched again. That's no good. [ 0.829997] DOUG: my_pm_clk_resume, usage=1 [ 0.835487] DOUG: my_pm_clk_resume, usage=1 When I disabled serial console (speeding up boot), I got a different pattern, which I guess (?) is better: [ 0.089767] DOUG: my_pm_clk_resume, usage=1 [ 0.090507] DOUG: my_pm_clk_resume, usage=1 [ 0.151885] DOUG: my_pm_clk_suspend, usage=-2 [ 0.151914] DOUG: my_pm_clk_suspend, usage=-2 [ 1.825747] DOUG: my_pm_clk_resume, usage=-1 [ 1.825774] DOUG: my_pm_clk_resume, usage=-1 [ 1.888269] DOUG: my_pm_clk_suspend, usage=-2 [ 1.888282] DOUG: my_pm_clk_suspend, usage=-2 These different patterns have to do with the fact that the core PM Runtime code really isn't designed to be robust to negative usage counts and sometimes may happen to stumble upon a behavior that happens to "work". For instance, you can see that __pm_runtime_suspend() will treat any non-zero value (including negative numbers) as if the device is in use. In any case, let's fix the driver to be correct. We'll hold a pm_runtime reference for the whole probe and then drop it (once!) at the end. We'll get rid of manual pm_runtime_disable() calls in the error handling. We'll also switch to devm_pm_runtime_enable(), which magically handles undoing pm_runtime_use_autosuspend() as of commit b4060db9251f ("PM: runtime: Have devm_pm_runtime_enable() handle pm_runtime_dont_use_autosuspend()"). While we're at this, let's also use devm_pm_clk_create() instead of rolling it ourselves. Note that the above changes make it obvious that lpassaudio_create_pm_clks() was doing more than just creating clocks. It was also setting up pm_runtime parameters. Let's rename it. All of these problems were found by code inspection. I started looking at this driver because it was involved in a deadlock that I reported a while ago [1]. Though I bisected the deadlock to commit 1b771839de05 ("clk: qcom: gdsc: enable optional power domain support"), it was never really clear why that patch affected it other than a luck of timing changes. I'll also note that by fixing the timing (as done in this change) we also seem to aboid the deadlock, which is a nice benefit. Also note that some of the fixes here are much the same type of stuff that Dmitry did in commit 72cfc73f4663 ("clk: qcom: use devm_pm_runtime_enable and devm_pm_clk_create"), but I guess lpassaudiocc-sc7280.c didn't exist then.
