[PATCH V2 0/7] i2c-imx-lpi2c: add IPG clock

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@xxxxxxx>

V2:
 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.

Peng Fan (7):
  ARM: dts: imx7ulp: update the LPI2C clock-names
  dt-bindings: i2c: i2c-imx-lpi2c: add ipg clk
  dt-bindings: i2c: i2c-imx-lpi2c: add dmas property
  dt-bindings: i2c: i2c-imx-lpi2c: add i.MX93
  arm64: dts: imx8-ss-dma: add IPG clock for i2c
  ARM: dts: imx7ulp: Add IPG clock for lpi2c
  i2c: imx-lpi2c: use bulk clk API
