dm: Add a clock uclass Clocks are an important feature of platforms and have become increasing complex with time. Most modern SoCs have multiple PLLs and dozens of clock dividers which distribute clocks to on-chip peripherals. Some SoC implementations have a clock API which is private to that SoC family, e.g. Tegra and Exynos. This is useful but it would be better to have a common API that can be understood and used throughout U-Boot. Add a simple clock API as a starting point. It supports querying and setting the rate of a clock. Each clock is a device. To reduce memory and processing overhead the concept of peripheral clocks is provided. These do not need to be explicit devices - it is possible to write a driver that can adjust the I2C clock (for example) without an explicit I2C clock device. This can dramatically reduce the number of devices (and associated overhead) in a complex SoC. Clocks are referenced by a number, and it is expected that SoCs will define that numbering themselves via an enum. Signed-off-by: Simon Glass <sjg@chromium.org>

clock: add Tegra186 clock driver In Tegra186, on-SoC clocks are manipulated using IPC requests to the BPMP (Boot and Power Management Processor). This change implements a driver that does that. A tegra/ sub-directory is created to follow the existing pattern. It is unconditionally selected by CONFIG_TEGRA186 since virtually any Tegra186 build of U-Boot will need the feature.

driver: clk: Add support for clocks on Armada 37xx The drivers are based on Linux driver by Gregory Clement. The TBG clocks support only the .get_rate method. - since setting rate is not supported, the driver computes the rates when probing and so subsequent calls to the .get_rate method do not read the corresponding registers again The peripheral clocks support methods .get_rate, .enable and .disable. - the .set_parent method theoretically could be supported on some clocks (the parent would have to be one of the TBG clocks) - the .set_rate method would have to try all the divider values to find the best approximation of a given rate, and it doesn't seem like this should be needed in U-Boot, therefore not implemented Signed-off-by: Marek Behun <marek.behun@nic.cz> Reviewed-by: Stefan Roese <sr@denx.de> Signed-off-by: Stefan Roese <sr@denx.de>

ARC: clk: introduce HSDK CGU clock driver Synopsys HSDK clock controller generates and supplies clocks to various controllers and peripherals within the SoC. Each clock has assigned identifier and client device tree nodes can use this identifier to specify the clock which they consume. All available clocks are defined as preprocessor macros in the dt-bindings/clock/snps,hsdk-cgu.h header and can be used in device tree sources.
