clk: imx8mq: remove SYS PLL 1/2 clock gates

2021-06-14T14:05:45Z

Remove the PLL clock gates as the allowing to gate the sys1_pll_266m breaks the uSDHC module which is sporadically unable to enumerate devices after this change. Also it makes AMP clock management harder with no obvious benefit to Linux, so just revert the change.

clk: imx8mq: add PLL monitor output

2021-01-30T13:35:15Z

The PLL monitor is mentioned as a debug feature in the reference manual, but there are some boards that use this clock output as a reference clock for board level components. Add support for those clocks in the clock driver, so this clock output can be used properly. Note that the VIDEO1, GPU and VPU mux inputs are rotated compared to the description in the reference manual. The order in this patch has been empirically validated.

clk: imx: imx8mq: fix a53 cpu clock

2020-02-24T07:39:56Z

The A53 CCM clk root only accepts input up to 1GHz, CCM A53 root signoff timing is 1Ghz, however the A53 core which sources from CCM root could run above 1GHz which violates the CCM. There is a CORE_SEL slice before A53 core, we need to configure the CORE_SEL slice source from ARM PLL, not A53 CCM clk root. The A53 CCM clk root should only be used when need to change ARM PLL frequency. Add arm_a53_core clk that could source from arm_a53_div and arm_pll_out. Configure a53 ccm root sources from 800MHz sys pll Configure a53 core sources from arm_pll_out Mark arm_a53_core as critical clock Fixes: db27e40b27f1 ("clk: imx8mq: Add the missing ARM clock") Reviewed-by: Jacky Bai Signed-off-by: Peng Fan Signed-off-by: Shawn Guo

dt-bindings: clock: imx8mq: Fix numbering overlaps and gaps

2019-03-12T20:40:10Z

IMX8MQ_CLK_USB_PHY_REF changes from 163 to 153, this way removing the gap. All the following clock ids are now decreased by 10 to keep the numbering right. Doing this, the IMX8MQ_CLK_CSI2_CORE is not overlapped with IMX8MQ_CLK_GPT1 anymore. IMX8MQ_CLK_GPT1_ROOT changes from 193 to 183 and all the following ids are updated accordingly.
