2024-07-06clk: clk-mux: Make public the clk_fetch_parent_indexMichael Trimarchi1-0/+1
Make public the clk_fetch_parent_index and rename it. This allow us to be reused in driver specialization Signed-off-by: Michael Trimarchi <michael@amarulasolutions.com>
2023-02-10Correct SPL uses of SANDBOX_CLK_CCFSimon Glass1-3/+3
This converts 12 usages of this option to the non-SPL form, since there is no SPL_SANDBOX_CLK_CCF defined in Kconfig Signed-off-by: Simon Glass <sjg@chromium.org>
2022-03-30clk: ccf: Add some helper functions for clock opsSean Anderson1-0/+8
Most CCF drivers follow a common pattern where their clock ops defer the actual operation to the backing CCF clock. Add some generic implementations of these functions to reduce duplication of code.

2021-06-11clk: fixed_rate: add API for directly registering fixed rate clocksTero Kristo1-0/+3
Current driver only supports registering fixed rate clocks from DT. Add new API which makes it possible to register fixed rate clocks directly from e.g. platform specific clock drivers.

2021-03-26clk: fixed-rate: Export driver parts for OF_PLATDATA_INSTSimon Glass1-0/+5
We need to allow SoCs to create their own drivers for this so that they can use their own of-platdata structs. To minimise code duplication, export the driver operations and the ofdata_to_plat() setup function. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

2020-08-03clk: Drop dm.h header file in clk-provider.hSimon Glass1-5/+3
This header file should not be included in other header files. Remove it and use a forward declaration and un-inlining of dev_get_clk_ptr() instead. Fix up the kendryte header files to avoid build errors. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Sean Anderson <seanga2@gmail.com>
2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass1-0/+1
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2020-01-26clk: Include missing headers for linux/clk-provider.hSean Anderson1-0/+4

2019-07-19clk: sandbox: Adjust clk-mux.c to emulate reading divider value from HWLukasz Majewski1-0/+4
The generic mux clock code for CCF requires reading the clock multiplexer value from HW registers. As sandbox by design has readl() as no-op it was necessary to provide this value in the other way. The new field in the mux structure (accessible only when sandbox is run) has been introduced for this purpose. Signed-off-by: Lukasz Majewski <lukma@denx.de>

2019-07-19clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12)Lukasz Majewski1-0/+109
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.
