2023-07-19clk: Explicitly include correct DT includesRob Herring2-3/+1
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.

2023-06-08clk: actions: composite: fact: Switch to determine_rateMaxime Ripard1-6/+12
The Actions composite factor 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: actions: composite: Add a determine_rate hook for pass clkMaxime Ripard1-0/+1
The Actions "Pass" 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. Similarly, it doesn't look like the device tree using that clock driver uses any of the assigned-clock properties. 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 latter 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. And if it was an oversight, then we are at least explicit about our behavior now and it can be further refined down the line.

2021-06-27clk: actions: Fix AHPPREDIV-H-AHB clock chain on Owl S500 SoCCristian Ciocaltea1-8/+11
There are a few issues with the setup of the Actions Semi Owl S500 SoC's clock chain involving AHPPREDIV, H and AHB clocks: * AHBPREDIV clock is defined as a muxer only, although it also acts as a divider. * H clock is using a wrong divider register offset * AHB is defined as a multi-rate factor clock, but it is actually just a fixed pass clock. Let's provide the following fixes: * Change AHBPREDIV clock to an ungated OWL_COMP_DIV definition. * Use the correct register shift value in the OWL_DIVIDER definition for H clock * Drop the unneeded 'ahb_factor_table[]' and change AHB clock to an ungated OWL_COMP_FIXED_FACTOR definition.

2021-06-27clk: actions: Fix bisp_factor_table based clocks on Owl S500 SoCCristian Ciocaltea1-15/+29
The following clocks of the Actions Semi Owl S500 SoC have been defined to use a shared clock factor table 'bisp_factor_table[]': DE[1-2], VCE, VDE, BISP, SENSOR[0-1] There are several issues involved in this approach: * 'bisp_factor_table[]' describes the configuration of a regular 8-rates divider, so its usage is redundant. Additionally, judging by the BISP clock context, it is incomplete since it maps only 8 out of 12 possible entries. * The clocks mentioned above are not identical in terms of the available rates, therefore cannot rely on the same factor table. Specifically, BISP and SENSOR* are standard 12-rate dividers so their configuration should rely on a proper clock div table, while VCE and VDE require a factor table that is a actually a subset of the one needed for DE[1-2] clocks. Let's fix this by implementing the following: * Add new factor tables 'de_factor_table' and 'hde_factor_table' to properly handle DE[1-2], VCE and VDE clocks. * Add a common div table 'std12rate_div_table' for BISP and SENSOR[0-1] clocks converted to OWL_COMP_DIV. * Drop the now unused 'bisp_factor_table[]'. Additionally, drop the CLK_IGNORE_UNUSED flag for SENSOR[0-1] since there is no reason to always keep ON those clocks.

2019-09-17clk: actions: Fix factor clk struct member accessManivannan Sadhasivam1-4/+3
Since the helper "owl_factor_helper_round_rate" is shared between factor and composite clocks, using the factor clk specific helper function like "hw_to_owl_factor" to access its members will create issues when called from composite clk specific code. Hence, pass the "factor_hw" struct pointer directly instead of fetching it using factor clk specific helpers. This issue has been observed when a composite clock like "sd0_clk" tried to call "owl_factor_helper_round_rate" resulting in pointer dereferencing error. While we are at it, let's rename the "clk_val_best" function to "owl_clk_val_best" since this is an owl SoCs specific helper.
