>  use clk bulk API in driver to support backward compatibility.
>  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.
