I'am running into the issue that my linux next-20190904 unfortunately is not booting with it on my imx8QM board. Kernel is just stuck during boot see below. I applied your v5 of your clock binding patches series and applied this series in v3. Your former two patch series worked well with next-20190716. The last messages from the kernel are: [ 1.019208] imx-scu scu: mbox_request_channel_byname() could not locate channel named "gip3" [ 1.027316] imx-scu scu: failed to request mbox chan gip3, ret -22 [ 1.033480] imx-scu scu: failed to enable general irq channel: -22 [ 1.039646] imx-scu scu: NXP i.MX SCU Initialized [ 1.047414] a35_clk: failed to get clock rate -22 [ 1.058682] lcd0-pwm0: failed to power up resource 188 ret -22 [ 1.064314] imx-scu-clk: probe of pwm_clk failed with error -22 [ 1.070538] lcd0: failed to power up resource 187 ret -22 [ 1.075690] imx-scu-clk: probe of lcd_clk failed with error -22 [ 1.085965] mipi_csi0_core_clk: failed to attached the power domain -2 [ 1.092359] mipi_csi0_esc_clk: failed to attached the power domain -2 [ 1.098777] mipi_csi0_i2c0_clk: failed to attached the power domain -2 [ 1.105278] mipi_csi0_pwm0_clk: failed to attached the power domain -2 [ 1.115744] imx8qm-pinctrl scu:pinctrl: initialized IMX pinctrl driver [ 1.123923] gpio-mxc 5d080000.gpio: IRQ index 1 not found [ 1.130276] gpio-mxc 5d090000.gpio: IRQ index 1 not found I see similar messages also with your older working patches, only the last two lines are new errors.
