clk: Tighten some clock driver dependencies

2025-10-28T18:25:23Z

A few clock drivers cannot build without access to some platform specific header files. Express those requirements in Kconfig as well. Signed-off-by: Tom Rini

clk: at91: Add support for sam9x60 USB clock

2023-03-27T11:27:37Z

Implement sam9x60 USB clock driver. This clock has three parents: PLLA, UPLL and MAINXTAL. The driver is aware of the three possible parents with the help of the two mux tables provied to the driver during the registration of the clock.

clk: at91: add USB Host clock driver

2018-03-16T11:30:04Z

Add USB clock driver to configure the input clock and the divider in the PMC_USB register to generate a 48MHz and a 12MHz signal to the USB Host OHCI. Signed-off-by: Wenyou Yang

clk: at91: Kconfig: fix the dependency of AT91_UTMI

2017-11-30T03:30:50Z

What the AT91_UTMI depends on SPL_DM isn't right. AT91_UTMI is not only used in SPL, also in other place, even if SPL_DM isn't enabled. Signed-off-by: Wenyou Yang

clk: at91: utmi: Set the reference clock frequency

2017-09-14T20:02:29Z

By default, it is assumed that the UTMI clock is generated from a 12 MHz reference clock (MAINCK). If it's not the case, the FREQ field of the SFR_UTMICKTRIM has to be updated to generate the UTMI clock in the proper way. The UTMI clock has a fixed rate of 480 MHz. In fact, there is no multiplier we can configure. The multiplier is managed internally, depending on the reference clock frequency, to achieve the target of 480 MHz. The patch is cloned from the patch of mailing-list: [PATCH v2] clk: at91: utmi: set the mainck rate Signed-off-by: Wenyou Yang [trini: Depend on SPL_DM] Signed-off-by: Tom Rini

clk: at91: Improve the clock implementation

2016-10-28T16:37:14Z

For the peripheral clock, provide the clock ops for the clock provider, such as spi0_clk. The .of_xlate is to get the clk->id, the .enable is to enable the spi0 peripheral clock, the .get_rate is to get the clock frequency. The driver for periph32ck node is responsible for recursively binding its children as clk devices, not provide the clock ops. So do the generated clock and system clock.

clk: at91: Add clock driver
