Merge tag 'imx-clk-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into clk-imx

Pull i.MX clk driver updates from Shawn Guo:

 - A series from Abel Vesa to do some trivial cleanups which will be
   helpful for i.MX clock driver switching to clk_hw based API
 - A series from Anson Huang to add i.MX8MP clock driver support
 - Disable non-functional divider between pll4_audio_div and
   pll4_post_div on imx6q
 - Fix watchdog2 clock name typo in imx7ulp clock driver
 - A couple of patches from Leonard Crestez to set CLK_GET_RATE_NOCACHE
   flag for DRAM related clocks on i.MX8M SoCs
 - Suppress bind attrs for i.MX8M clock driver to avoid the possibility
   of reloading the driver at runtime
 - Add a big comment in imx8qxp-lpcg driver to tell why
   devm_platform_ioremap_resource() shouldn't be used for the driver
 - A correction on i.MX8MN usb1_ctrl parent clock setting
 - A couple of trivial cleanup on clk-divider-gate driver
 - A series from Peng Fan to convert i.MX8M clock drivers to clk_hw
   based API
