Include a new patch, patch 1. The i.MX LPI2C needs PER and IPG clock, not just PER or IPG clock. The current driver/dts/bindings use one CLK. Although it works with with upstream kernel, but it not match the hardware design. If IPG clock is disabled, the LPI2C will not work. There are changes made to ARM32 i.MX7ULP dts, ARM64 i.MX8 dts, dt-bindings, and the lpi2c driver. The driver is updated to use bulk clk API to avoid break backward compatibility. But it is hard to avoid dtbs_check pass, because the dts and binding update are in separate patches.
