x86: Add a clock driver for Intel devices

2020-02-07T14:41:24Z

So far we have avoided adding a clock driver for Intel devices. But the Designware I2C driver needs a different clock (133MHz) on Intel devices than on others (166MHz). Add a simple driver that provides this information. This driver can be expanded later as needed. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

clk: add clock driver for MediaTek MT76x8 platform

2019-10-25T15:20:44Z

This patch adds a clock driver for MediaTek MT7628/7688 SoC. It provides clock gate control as well as getting clock frequency for CPU/SYS/XTAL and some peripherals. Signed-off-by: Weijie Gao

clk: cdce9xx: add support for cdce9xx clock synthesizer

2019-10-11T17:32:39Z

Add support for CDCE913/925/937/949 family of devices. These are modular PLL-based low cost, high performance, programmable clock synthesizers, multipliers and dividers. They generate up to 9 output clocks from a single input frequency. The initial version of the driver does not support programming of the PLLs, and thus they run in the bypass mode only. The code is loosely based on the linux kernel cdce9xx driver. Signed-off-by: Tero Kristo

clk: versal: Add clock driver support

2019-10-08T07:41:24Z

This patch adds clock driver support for Versal platform. The clock driver queries and performs clock operations using PLM firmware by communicating with it using SMC calls. Signed-off-by: Siva Durga Prasad Paladugu Signed-off-by: Michal Simek

clk: sandbox: Add sandbox test code for Common Clock Framework [CCF]

2019-07-19T12:50:30Z

This patch provides code to implement the CCF clock tree in sandbox. It uses all the introduced primitives; some generic ones are reused, some sandbox specific were developed. In that way (after introducing the real CCF tree in sandbox) the recently added to clk-uclass.c: clk_get_by_id() and clk_get_parent_rate() are tested in their natural work environment. Usage (sandbox_defconfig and sandbox_flattree_defconfig): ./u-boot --fdt arch/sandbox/dts/test.dtb --command "ut dm clk_ccf" Signed-off-by: Lukasz Majewski

clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12)

2019-07-19T12:50:30Z

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.
