The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

/* * (c) 2015 Purna Chandra Mandal <purna.mandal@microchip.com> */ PIC32MZ[DA] Starter Kit ---------------------------------------- PIC32MZ[DA] Starter Kit is based on PIC32MZ[DA] family of micro-controller. This family is powered by MIPS M14KEC 32bit general purpose core and has advanced microcontroller features and peripherals. This processor boots with proprietary stage1 bootloader running from internal boot-flash. Stage1 bootloader inturns locates and jumps to U-Boot programmed on internal program-flash. Finally U-Boot loads OS image (along with other required files for booting) from either uSD card, or ethernet, or from USB storage. To boot Linux following three files are mandatory - uEnv.txt (custom U-Boot environment file), uImage, *.dtb (platform device-tree-blob file). U-Boot jumps to Linux using UHI specification.
