Rajan Vaja authored
Currently firmware passes CCF specific flags to ZynqMP clock driver. So firmware needs to be updated if CCF flags are changed. The firmware should have its own 'flag number space' that is distinct from the common clk framework's 'flag number space'. So define and use ZynqMP specific common clock flags instead of using CCF flags. Signed-off-by:

Platform STM32MP1 can be used in configuration where some clock resources cannot be accessed by Linux kernel when executing in non-secure state of the CPU(s). In such configuration, the RCC clock driver must not register clocks it cannot access. They are expected to be registered from another clock driver such as the SCMI clock driver. This change uses specific compatible string "st,stm32mp1-rcc-secure" to specify RCC clock driver configuration where RCC is secure. Signed-off-by:

Paul Cercueil authored
When a clock is declared as both CGU_CLK_DIV and CGU_CLK_MUX, the CGU code expects the mux to be applied first, the divider second. On the JZ4760, and maybe on some other SoCs, some clocks also have a mux setting and a divider, but the divider is not applied to all parents selectable from the mux. This could be solved by creating two clocks, one with CGU_CLK_DIV and one with CGU_CLK_MUX, but that would increase the number of clocks. Instead, add a 8-bit mask to CGU_CLK_DIV clocks. If the bit corresponding to the parent clock's index is set, the divider is bypassed. Signed-off-by:

Cristian Ciocaltea authored
There are a few issues with the setup of the Actions Semi Owl S500 SoC's clock chain involving AHPPREDIV, H and AHB clocks: * AHBPREDIV clock is defined as a muxer only, although it also acts as a divider. * H clock is using a wrong divider register offset * AHB is defined as a multi-rate factor clock, but it is actually just a fixed pass clock. Let's provide the following fixes: * Change AHBPREDIV clock to an ungated OWL_COMP_DIV definition. * Use the correct register shift value in the OWL_DIVIDER definition for H clock * Drop the unneeded 'ahb_factor_table[]' and change AHB clock to an ungated OWL_COMP_FIXED_FACTOR definition.

The following clocks of the Actions Semi Owl S500 SoC have been defined to use a shared clock factor table 'bisp_factor_table[]': DE[1-2], VCE, VDE, BISP, SENSOR[0-1] There are several issues involved in this approach: * 'bisp_factor_table[]' describes the configuration of a regular 8-rates divider, so its usage is redundant. Additionally, judging by the BISP clock context, it is incomplete since it maps only 8 out of 12 possible entries. * The clocks mentioned above are not identical in terms of the available rates, therefore cannot rely on the same factor table. Specifically, BISP and SENSOR* are standard 12-rate dividers so their configuration should rely on a proper clock div table, while VCE and VDE require a factor table that is a actually a subset of the one needed for DE[1-2] clocks. Let's fix this by implementing the following: * Add new factor tables 'de_factor_table' and 'hde_factor_table' to properly handle DE[1-2], VCE and VDE clocks. * Add a common div table 'std12rate_div_table' for BISP and SENSOR[0-1] clocks converted to OWL_COMP_DIV. * Drop the now unused 'bisp_factor_table[]'. Additionally, drop the CLK_IGNORE_UNUSED flag for SENSOR[0-1] since there is no reason to always keep ON those clocks. Fixes: ed6b4795 ("clk: actions: Add clock driver for S500 SoC") Signed-off-by:

The digital delay allows outputs to be delayed from 8 to 1023 VCO cycles. The delay step can be as small as half the period of the clock distribution path. For example, a 3.2-GHz VCO frequency results in 156.25-ps steps. The digital delay value takes effect on the clock output phase after a SYNC event. This is required to support JESD204B subclass 1.
