Pull clk patches from Brian Masney: - New clock controller drivers for the Cix Sky1 audio subsystem (AUDSS), UltraRISC DP1000, and MediaTek MT8173 MFG_TOP, along with their devicetree bindings. Si549 support was added to the existing si544 driver. - New clock and reset support for the Aspeed AST2700 PECI controller and Airoha EN7523 PCIe PERSTOUT reset lines. - The clk core gains devm_clk_bulk_get_enable() as the mandatory counterpart to the existing optional variant, and exports devm_clk_hw_register_composite_pdata() for modular drivers. - Tegra gets a proper EMC clock implementation for Tegra114, 48MHz pll_p_out1 support needed for UEFI on Surface2, and the Xilinx clocking-wizard gains PLL charge pump/lock parameter programming during dynamic reconfiguration. - Bug fixes for a NULL pointer dereference from uninitialized clk_init_data in the eswin driver, an IO remap leak in the MediaTek pllfh error path, inverted gate control for MT8135 devapc_ck, a missing OF node put in tegra124-emc on registration failure, a prepare reference leak in the palmas driver, unregistered PLLs on MT6735 probe failure, a missing kasprintf NULL check in pmc_atom, PCIe warm boot instability in the Airoha EN7523 driver, and a clocking-wizard clock difference detection bug. - Various cleanups across tegra, st, and mvebu providers to stop misusing the consumer clock API, along with other minor fixes and improvements.

| 14 | + audio-related clock muxing, gating and block-level software reset control | |
| 15 | + in a single register block. | |
| 16 | + | |
| 17 | + A single device node exposes both the clock controller and software reset | |
| 18 | + lines. The clock driver registers as a platform driver; the reset controller | |
| 19 | + is registered by an auxiliary driver bound from the clock driver. | |
| 20 | + | |
| 21 | + Four SoC-level reference clocks listed in clocks/clock-names feed the AUDSS | |
| 22 | + clock tree. Internal AUDSS clocks are exposed via #clock-cells; indices are | |
| 23 | + defined in include/dt-bindings/clock/cix,sky1-audss-cru.h. | |
| 24 | + | |
| 25 | + Block-level software reset indices are exposed via #reset-cells; indices | |
| 26 | + are defined in include/dt-bindings/reset/cix,sky1-audss-cru.h. | |
| 27 | + | |
| 28 | + The SoC syscon NoC (or bus) reset is described via resets. The audio | |
| 29 | + subsystem power domain is described via power-domains. | |
