2023-03-21clk: rs9: Fix suspend/resumeAlexander Stein
Disabling the cache in commit 2ff4ba9e3702 ("clk: rs9: Fix I2C accessors") without removing cache synchronization in resume path results in a kernel panic as map->cache_ops is unset, due to REGCACHE_NONE. Enable flat cache again to support resume again. num_reg_defaults_raw is necessary to read the cache defaults from hardware. Some registers are strapped in hardware and cannot be provided in software.

In sprd clock driver, regmap_config.max_register was set to a fixed value which is likely larger than the address range configured in device tree, when reading registers through debugfs it would cause access violation.

The K210 clock driver depends on SOC_CANAAN, which is only selectable when !MMU on RISC-V. !MMU is not possible on 32-bit yet, but patches have been sent for its enabling.

2023-03-06clk: HI655X: select REGMAP instead of depending on itRandy Dunlap
REGMAP is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change the use of "depends on REGMAP" to "select REGMAP".

2023-03-06kbuild, clk: remove MODULE_LICENSE in non-modulesNick Alcock
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.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have one small patch to the clk core this time around. It fixes a corner case with the CLK_OPS_PARENT_ENABLE flag combined with clk_core_is_enabled() where it hangs the system. We'll simply assume the clk is disabled if the parent is disabled and the flag is set. Trying to turn on the parent to check the enable state of the clk runs into system hangs at boot. We let this bake in -next for a couple weeks to make sure there aren't any more issues because the last attempt to fix this ran into hangs and had to be reverted. Note: There were some more patches to the core framework around sync_state and disabling unused clks, but I asked for that to be reverted from the qcom PR because it isn't ready and we're still discussing the best solution on the list. Outside of the core clk framework, we have the usual collection of clk driver updates and support for new SoCs (which seems to never stop). The dirstat is dominated by Qualcomm because they added support for quite a few SoCs this time around and also migrated quite a few of their drivers to clk_parent_data. The other big diff is in the Mediatek clk drivers that saw a significant rework this cycle to similarly modernize the code, and we'll see that work continue in the next cycle as well. Nothing really jumps out as scary here, except that the significant churn in parent data descriptions can have typos that go unnoticed. More details below.

This branch is almost exclusively dead code removal based on those annotations. Some device driver removals went through separate subsystem trees, but the majority is in the same branch, in order to better handle dependencies between the patches and avoid breaking bisection. Unfortunately that leads to merge conflicts against other changes in the subsystem trees, but they should all be trivial to resolve by removing the files.

The problem is in 'mt7621_gate_is_enabled()' function which is using the 'BIT()' kernel macro with the bit index for the clock gate to check if the bit is set. When the clock gates structure is created driver is already setting 'bit_idx' using 'BIT()' macro, so we are wrongly applying an extra 'BIT()' mask here. Removing it solve the problem and makes this function correct. However when clock gating is correctly working, the kernel starts disabling those clocks that are not requested. Some drivers for this SoC are older than this clock driver itself. So to avoid the kernel to disable clocks that have been enabled until now, we must apply 'CLK_IS_CRITICAL' flag on gates initialization code.

2023-02-10clk: Honor CLK_OPS_PARENT_ENABLE in clk_core_is_enabled()Chen-Yu Tsai
In the previous commits that added CLK_OPS_PARENT_ENABLE, support for this flag was only added to rate change operations (rate setting and reparent) and disabling unused subtree. It was not added to the clock gate related operations. Any hardware driver that needs it for these operations will either see bogus results, or worse, hang. This has been seen on MT8192 and MT8195, where the imp_ii2_* clk drivers set this, but dumping debugfs clk_summary would cause it to hang. Prepare parent on prepare and enable parent on enable dependencies are already handled automatically by the core as part of its sequencing. Whether the case for "enable parent on prepare" should be supported by this flag or not is not clear, and thus ignored for now. This change solely fixes the handling of clk_core_is_enabled, i.e. enabling the parent clock when reading the hardware state. Unfortunately clk_core_is_enabled is called in a variety of places, sometimes with the enable clock already held. To avoid deadlocking, the core will ignore readouts and just return false if CLK_OPS_PARENT_ENABLE is set but the parent isn't currently enabled.

2023-01-30clk: mediatek: mt8192: Join top_adj_divs and top_muxesAngeloGioacchino Del Regno
These two are both mtk_composite arrays, one dependent on another, but that's something that the clock framework is supposed to sort out and anyway registering them separately isn't going to ease the framework's job in checking dependencies. Put the contents of top_adj_divs in top_muxes to join them together and register them in one shot.

2023-01-30clk: mediatek: clk-mt8192: Move CLK_TOP_CSW_F26M_D2 in top_divsAngeloGioacchino Del Regno
This driver is registered early in clk_mt8192_top_init_early() and then again in clk_mt8192_top_probe(): the difference between the two is that the early one is probed with CLK_OF_DECLARE_DRIVER and the latter is regularly probed as a platform_driver. Knowing that it is not necessary for this platform to register the TOP_CSW_F26M_D2 clock that early, move it to top_divs and register it with the others during platform_driver probe for topckgen; While at it, since the only reason why the early probe existed was to register that clock, remove that entirely - leaving this driver to use only platform_driver.
