2025-05-29clk: renesas: rzg2l-cpg: Refactor Runtime PM clock validationLad Prabhakar
[ Upstream commit f6f73b891bf6beff069fcacc7b4a796e1009bf26 ] Refactor rzg2l_cpg_attach_dev to delegate clock validation for Runtime PM to the updated rzg2l_cpg_is_pm_clk function. Ensure validation of clocks associated with the power domain while excluding external and core clocks. Prevent incorrect Runtime PM management for clocks outside the domain's scope. Update rzg2l_cpg_is_pm_clk to operate on a per-power-domain basis. Verify clkspec.np against the domain's device node, check argument validity, and validate clock type (CPG_MOD). Use the no_pm_mod_clks array to exclude specific clocks from PM management.

2025-04-20clk: renesas: r9a07g043: Fix HP clock source for RZ/FiveLad Prabhakar
commit 7f22a298d926664b51fcfe2f8ea5feb7f8b79952 upstream. According to the Rev.1.20 hardware manual for the RZ/Five SoC, the clock source for HP is derived from PLL6 divided by 2. Correct the implementation by configuring HP as a fixed clock source instead of a MUX. The `CPG_PL6_ETH_SSEL' register, which is available on the RZ/G2UL SoC, is not present on the RZ/Five SoC, necessitating this change.

2025-04-10clk: renesas: r8a08g045: Check the source of the CPU PLL settingsClaudiu Beznea
[ Upstream commit dc0f16c1b76293ac942a783e960abfd19e95fdf5 ] On the RZ/G3S SoC, the CPU PLL settings can be set and retrieved through the CPG_PLL1_CLK1 and CPG_PLL1_CLK2 registers. However, these settings are applied only when CPG_PLL1_SETTING.SEL_PLL1 is set to 0. Otherwise, the CPU PLL operates at the default frequency of 1.1 GHz. Hence add support to the PLL driver for returning the 1.1 GHz frequency when the CPU PLL is configured with the default frequency.

[ Upstream commit a6ca7e6240f0651412da6a17d0e7a8f66d3455a6 ] A device_node reference obtained via of_find_node_by_path() requires explicit calls to of_node_put() after it is no longer required to avoid leaking the resource. Instead of adding the missing calls to of_node_put() in all execution paths, use the cleanup attribute for 'soc' by means of the __free() macro, which automatically calls of_node_put() when the variable goes out of scope.

2024-09-21clk: Switch back to struct platform_driver::remove()Uwe Kleine-König
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.
