Merge tag 'clk-misc-round-two-for-v7.3' of ssh://github.com/masneyb/linux into clk-pile
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.
