Tegra PMC has clk_out_1, clk_out_2, clk_out_3 and blink controls which are currently registered by Tegra clock driver using clk_regiser_mux and clk_register_gate which performs direct Tegra PMC register access. When Tegra PMC is in secure mode, any access from non-secure world will not go through. This patch series adds these Tegra PMC clocks and blink controls to Tegra PMC driver with PMC as clock provider and removed them from Tegra clock driver. This also adds PMC specific clock id's to use in device tree and removed clock ids of PMC clock from Tegra clock driver. This series also includes patch to update clock provider from tegra_car to pmc in the device tree tegra210-smaug.dts that uses clk_out_2 from PMC. [v2]: Changes between v1 and v2 are - v2 includes patches for adding clk_out_1, clk_out_2, clk_out_3, blink controls to Tegra PMC driver and removing clk-tegra-pmc. - feedback related to pmc clocks in Tegra PMC driver from v1 - Removed patches for WB0 PLLM overrides and PLLE IDDQ PMC programming by the clock driver using helper functions from Tegra PMC. Note: To use helper functions from PMC driver, PMC early init need to happen prior to using helper functions and these helper functions are for PLLM Override and PLLE IDDQ programming in PMC during PLLM/PLLE clock registration which happen in clock_init prior to Tegra PMC probe. Moving PLLM/PLLE clocks registration to happen after Tegra PMC impacts other clocks EMC, MC and corresponding tegra_emc_init and tegra_mc_init. This implementation of configuring PMC registers thru helper functions in clock driver needs proper changes across PMC, Clock, EMC and MC inits to have it work across all Tegra platforms. Currently PLLM Override is not enabled in the bootloader so proper patches for this fix will be taken care separately. [v1]: v1 includes patches for below fixes. - adding clk_out_1, clk_out_2, clk_out_3, blink controls to Tegra PMC driver and removing clk-tegra-pmc. - updated clock provider from tegra_car to pmc in the device tree tegra210-smaug.dts that uses clk_out_2. - Added helper functions in PMC driver for WB0 PLLM overrides and PLLE IDDQ programming to use by clock driver and updated clock driver to use these helper functions and removed direct PMC access from clock driver and all pmc base address references in clock driver.
