2023-07-19clk: Explicitly include correct DT includesRob Herring3-4/+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.

A clock used for the 3D graphics appears to be common among multiple SoC's, so add a generic gen3 clock for clocking the graphics. This is similar to the cpg_z_clk, with a different frequency control register and different flags. Instead of duplicating the code, make cpg_z_clk_register into a helper function and call the help function with the FCR and flags as a parameter.

2023-06-09clk: renesas: r9a06g032: Add a determine_rate hookMaxime Ripard1-0/+1
The Renesas r9a06g032 bitselect 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 on 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 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.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "Nothing looks out of the ordinary in this batch of clk driver updates. There are a couple patches to the core clk framework, but they're all basically cleanups or debugging aids. The driver updates and new additions are dominated in the diffstat by Qualcomm and MediaTek drivers. Qualcomm gained a handful of new drivers for various SoCs, and MediaTek gained a bunch of drivers for MT8188. The MediaTek drivers are being modernized as well, so there are updates all over that vendor's clk drivers. There's also a couple other new clk drivers in here, for example the Starfive JH7110 SoC support is added. Outside of the two major SoC vendors though, we have the usual collection of non-critical fixes and cleanups to various clk drivers. It's good to see that we're getting more cleanups and modernization patches. Maybe one day we'll be able to properly split clk providers from clk consumers.

Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

2023-03-16clk: renesas: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
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.

2023-03-10clk: renesas: r9a06g032: Improve clock tablesRalph Siemsen1-153/+407
Each entry in the clock table specifies a number of individual bits in registers, for contolling clock reset, gaiting, etc. These reg/bit were packed into a u16 to save space. The combined value is difficult to understand when reviewing the clock table entries. Introduce a "struct regbit" which still occupies only 16 bits, but allows the register and bit values to be specified explicitly. Convert all previous uses of u16 for reg/bit into "struct regbit". The bulk of this patch converts the clock table to use struct regbit, making use of the RB() helper macro. The conversion was automated by script, and as a further verification, the compiled binary of the table was compared before/after the change (with objdump -D). The clk_rdesc_set() function now checks for zero reg/bit internally. This allows callers of that function to remove those checks.

Currently the PLLs are modeled as fixed factor clocks, based on initial settings. However, enabling CPU boost clock rates requires increasing the PLL clock rates. Add a custom clock driver to model the PLL clocks on R-Car Gen4, and use it for PLL2 on R-Car V4H. This allows the Z clock (Cortex-A76 core clock) to request PLL rate changes, and enable boost mode for the High Performance mode. For now this is limited to integer multiplication modes. Note that the definition for CPG_PLLxCR0_NI uses the value for R-Car V4H. On R-Car S4-8, the integer and fractional multiplication fields are one bit larger resp. smaller, but R-Car S4-8 does not support High Performance mode.
