2023-04-09clk: imx: imx93: add mcore_booted module paratemterPeng Fan2-1/+9
Add mcore_booted boot parameter which could simplify AMP clock management. To i.MX93, there is CCM(clock control Module) to generate clock root clock, anatop(analog PLL module) to generate PLL, and LPCG (clock gating) to gate clocks to peripherals. As below: anatop->ccm->lpcg->peripheral Linux handles the clock management and the auxiliary core is under control of Linux. Although there is per hardware domain control for LPCG and CCM, auxiliary core normally only use LPCG hardware domain control to avoid linux gate off the clk to peripherals and leave CCM ana anatop to Linux.

2023-04-09clk: imx: fracn-gppll: support integer pllPeng Fan2-7/+68
The fracn gppll could be configured in FRAC or INTEGER mode during hardware design. The current driver only support FRAC mode, while this patch introduces INTEGER support. When the PLL is INTEGER pll, there is no mfn, mfd, the calculation is as below: Fvco_clk = (Fref / DIV[RDIV] ) * DIV[MFI] Fclko_odiv = Fvco_clk / DIV[ODIV] In this patch, we reuse the FRAC pll logic with some condition check to simplify the driver Signed-off-by: Peng Fan <peng.fan@nxp.com> Reviewed-by: Abel Vesa <abel.vesa@linaro.org> Link: https://lore.kernel.org/r/20230403095300.3386988-4-peng.fan@oss.nxp.com Signed-off-by: Abel Vesa <abel.vesa@linaro.org>

2023-03-31clk: imx: Let IMX8MN_CLK_DISP_PIXEL set parent rateAdam Ford1-1/+1
By default the display pixel clock needs to be evenly divide down from the video_pll_out clock which rules out a significant number of resolution and refresh rates.

2023-03-31clk: imx: composite-8m: Add support to determine_rateAdam Ford1-0/+7
Similar to imx/clk-composite-93 and imx/clk-divider-gate, the imx8m_clk_composite_divider_ops can support determine_rate. Without this the parent clocks are set to a fixed value, and if a consumer needs a slower reate, the clock is divided, but the division is only as good as the parent clock rate. With this added, the system can attempt to adjust the parent rate if the proper flags are set which can lead to a more precise clock value.
