2025-09-21clk: tegra: do not overallocate memory for bpmp clocksFedor Pchelkin1-1/+1
struct tegra_bpmp::clocks is a pointer to a dynamically allocated array of pointers to 'struct tegra_bpmp_clk'. But the size of the allocated area is calculated like it is an array containing actual 'struct tegra_bpmp_clk' objects - it's not true, there are just pointers.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all clk drivers to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2023-07-19clk: Explicitly include correct DT includesRob Herring5-5/+3
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

Commit 493ffb046cf5 ("clk: tegra: super: Switch to determine_rate") replaced clk_super_round_rate() by clk_super_determine_rate(), but didn't update one callsite that was explicitly calling the old tegra_clk_super_ops.round_rate() function, which was now NULL.

2023-06-08clk: tegra: super: Switch to determine_rateMaxime Ripard1-4/+11
The Tegra super clocks implements a mux with a set_parent hook, but doesn't provide a determine_rate implementation. This is a bit odd, since set_parent() is there to, as its name implies, change the parent of a clock. However, the most likely candidate to trigger that parent change is a call to clk_set_rate(), with determine_rate() figuring out which parent is the best suited for a given rate. The other trigger would be a call to clk_set_parent(), but it's far less used, and it doesn't look like there's any obvious user for that clock. So, the set_parent hook is effectively unused, possibly because of an oversight. However, it could also be an explicit decision by the original author to avoid any reparenting but through an explicit call to clk_set_parent(). The driver does implement round_rate() though, which means that we can change the rate of the clock, but we will never get to change the parent. However, It's hard to tell whether it's been done on purpose or not. Since we'll start mandating a determine_rate() implementation, let's convert the round_rate() implementation to a determine_rate(), which will also make the current behavior explicit. And if it was an oversight, the clock behaviour can be adjusted later on.

2023-06-08clk: tegra: periph: Add a determine_rate hookMaxime Ripard1-0/+1
The Tegra periph nodiv clock implements a mux with a set_parent hook, but doesn't provide a determine_rate implementation. This is a bit odd, since set_parent() is there to, as its name implies, change the parent of a clock. However, the most likely candidates to trigger that parent change are either the assigned-clock-parents device tree property or a call to clk_set_rate(), with determine_rate() figuring out which parent is the best suited for a given rate. The other trigger would be a call to clk_set_parent(), but it's far less used, and it doesn't look like there's any obvious user for that clock. However, the upstream device trees seem to use assigned-clock-parents on that clock to force the parent at boot time, so it's likely that the author intent was to force the parent through the device tree and prevent any reparenting but through an explicit call to clk_set_parent(). This case would be equivalent to setting the determine_rate implementation to clk_hw_determine_rate_no_reparent(). Indeed, if no determine_rate implementation is provided, clk_round_rate() (through clk_core_round_rate_nolock()) will call itself on the parent if CLK_SET_RATE_PARENT is set, and will not change the clock rate otherwise.

The Tegra super mux clock implements a mux with a set_parent hook, but doesn't provide a determine_rate implementation. This is a bit odd, since set_parent() is there to, as its name implies, change the parent of a clock. However, the most likely candidates to trigger that parent change are either the assigned-clock-parents device tree property or a call to clk_set_rate(), with determine_rate() figuring out which parent is the best suited for a given rate. The other trigger would be a call to clk_set_parent(), but it's far less used, and it doesn't look like there's any obvious user for that clock. However, the upstream device trees seem to use assigned-clock-parents on that clock to force the parent at boot time, so it's likely that the author intent was to force the parent through the device tree and prevent any reparenting but through an explicit call to clk_set_parent(). This case would be equivalent to setting the determine_rate implementation to clk_hw_determine_rate_no_reparent(). Indeed, if no determine_rate implementation is provided, clk_round_rate() (through clk_core_round_rate_nolock()) will call itself on the parent if CLK_SET_RATE_PARENT is set, and will not change the clock rate otherwise.

2023-03-28clk: tegra: Convert to platform remove callback returning voidUwe Kleine-König1-5/+3
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

tegra124_dfll_fcpu_remove() calls tegra_dfll_unregister() and the former emits an error message if the latter fails. In that case tegra_dfll_unregister() already printed an error message. Additionally tegra124_dfll_fcpu_remove() returns an error code which results in yet another warning emitted by platform_remove(). So drop the error message from tegra124_dfll_fcpu_remove() and let it return 0. (Retuning 0 has no side effect but suppressing the error message in platform_remove().) Also add two comments about exiting early being wrong. This is something that needs fixing separately.

Commit 8c193f4714df ("pwm: tegra: Optimize period calculation") updated the period calculation in the Tegra PWM driver and now returns an error if the period requested is less than minimum period supported. This is breaking PWM support on various Tegra platforms. For example, on the Tegra210 Jetson Nano platform this is breaking the PWM fan support and probing the PWM fan driver now fails ... pwm-fan pwm-fan: Failed to configure PWM: -22 pwm-fan: probe of pwm-fan failed with error -22 The problem is that the default parent clock for the PWM on Tegra210 is a 32kHz clock and is unable to support the requested PWM period. Fix PWM support on Tegra20, Tegra30, Tegra114, Tegra124 and Tegra210 by updating the parent clock for the PWM to be the PLL_P.

2022-05-04clk: tegra: Register clocks from root to leafTimo Alho1-16/+56
Current clock initialization causes intermediate registering of orphan clocks (i.e. a clock without a parent registered). CCF keeps track of orphan clocks and any time a new clock is registered, it will loop through the list of orphan and queries if the parent is now available. This operation triggers one or more clock operations, which are IPCs with BPMP-FW. Hence, due to the order in which the clocks appear currently, this causes > 5000 IPC messages to be sent to BPMP-FW during clock initialization.

2021-12-15clk: tegra: Support runtime PM and power domainDmitry Osipenko8-54/+420
The Clock-and-Reset controller resides in a core power domain on NVIDIA Tegra SoCs. In order to support voltage scaling of the core power domain, we hook up DVFS-capable clocks to the core GENPD for managing of the GENPD's performance state based on the clock changes. Some clocks don't have any specific physical hardware unit that backs them, like root PLLs and system clock and they have theirs own voltage requirements. This patch adds new clk-device driver that backs the clocks and provides runtime PM functionality for them. A virtual clk-device is created for each such DVFS-capable clock at the clock's registration time by the new tegra_clk_register() helper. Driver changes clock's device GENPD performance state based on clk-rate notifications. In result we have this sequence of events: 1. Clock driver creates virtual device for selective clocks, enables runtime PM for the created device and registers the clock. 2. Clk-device driver starts to listen to clock rate changes. 3. Something changes clk rate or enables/disables clk. 4. CCF core propagates the change through the clk tree. 5. Clk-device driver gets clock rate-change notification or GENPD core handles prepare/unprepare of the clock. 6. Clk-device driver changes GENPD performance state on clock rate change. 7. GENPD driver changes voltage regulator state change. 8. The regulator state is committed to hardware via I2C. We rely on fact that DVFS is not needed for Tegra I2C and that Tegra I2C driver already keeps clock always-prepared. Hence I2C subsystem stays independent from the clk power management and there are no deadlock spots in the sequence. Currently all clocks are registered very early during kernel boot when the device driver core isn't available yet. The clk-device can't be created at that time. This patch splits the registration of the clocks in two phases: 1. Register all essential clocks which don't use RPM and are needed during early boot. 2. Register at a later boot time the rest of clocks. This patch adds power management support for Tegra20 and Tegra30 clocks.
