Merge tag 'clk-imx-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/abelvesa/linux into clk-imx
Pull i.MX clk driver updates from Abel Vesa:
- Document bindings for i.MX93 ANATOP clock driver
- Free clk_node in SCU driver for resource with different owner
- Update the LVDS clocks to be compatible with SCU firmware 1.15
- Fix the name of the fvco in pll14xx by renaming it to fout
* tag 'clk-imx-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/abelvesa/linux:
clk: imx: pll14xx: change naming of fvco to fout
clk: imx: clk-imx8qxp: fix LVDS bypass, pixel and phy clocks
clk: imx: scu: Fix memory leak in __imx_clk_gpr_scu()
dt-bindings: clock: support i.MX93 ANATOP clock module
