menu "Clock"
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>

This allows drivers to be provided for clock generators, including
oscillators and PLLs. Devices can use a common clock API to request
a particular clock rate and check on available clocks. Clocks can
feed into other clocks in a tree structure, with multiplexers to
choose the source for each clock.

clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12) This patch brings the files from Linux kernel (linux-stable/linux-5.1.y SHA1: 5752b50477da)to provide clocks support as it is used on the Linux kernel with Common Clock Framework [CCF] setup. The directory structure has been preserved. The ported code only supports reading information from PLL, MUX, Divider, etc and enabling/disabling the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic to the alias numbering as the information about the clock is read from the device tree. One needs to pay attention to the comments indicating necessary for U-Boot's driver model changes. If needed, the code can be extended to support the "set" part of the clock management.

This provides very basic support for clocks on Intel SoCs. The driver

Much clock configuration in U-Boot is either set up by the FSP, or
set up by U-Boot itself but only statically. Thus the driver does not
support changing clock rates, only querying them.

bool "Enable clock driver support for ZynqMP"
depends on ARCH_ZYNQMP
arm64: zynqmp: Add missing ZYNQMP_FIRMWARE dependencies There are missing Kconfig dependencies in the code which is using firmware interface. The commit 71efd45a5fc7 ("arm64: zynqmp: Change firmware dependency") add option to also disable ZYNQMP_FIRMWARE. But not all Kconfig dependencies were properly described and also sdhci and gem drivers didn't protect the code properly. So, add the missing ZYNQMP_FIRMWARE dependencies.

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>
