Subject: [PATCH V2 00/18] i2c: imx-lpi2c: New features and bug fixes

Hi,

According to V1's feedback, V2 has been modified.
For summary of the changes, please refer to the header of each patch file.

Added some dt-bindings and dts patches.
At the same time, a patch has been added to fix the problem that data larger
than 256 bytes cannot be sent in one frame in PIO mode.

Clark Wang (14):
  i2c: imx-lpi2c: add ipg clk for lpi2c driver
  ARM: dts: imx7ulp: add the missing lpi2c ipg clock
  ARM: dts: imx7ulp: add the missing lpi2c nodes
  ARM64: dts: imx8: add the missing lpi2c ipg clock
  ARM64: dts: imx8: change i2c irq number to non-combined
  i2c: imx-lpi2c: increase PM timeout to avoid operate clk frequently
  i2c: imx-lpi2c: add bus recovery feature
  dt-bindings: i2c: imx-lpi2c: Add bus recovery example
  i2c: imx-lpi2c: fix i2c timing issue
  i2c: imx-lpi2c: fix type char overflow issue when calculating the
    clock cycle
  i2c: imx-lpi2c: add edma mode support
  dt-bindings: i2c: imx-lpi2c: Add dma configuration example
  ARM: dts: imx7ulp: add dma configurations for lpi2c
  ARM: dts: imx7ulp: add the missing status property of lpi2c5
  i2c: imx-lpi2c: fix pio mode cannot send 256+ bytes in one frame

Fugang Duan (1):
  i2c: imx-lpi2c: manage irq resource request/release in runtime pm

Gao Pan (2):
  i2c: imx-lpi2c: directly retrun ISR when detect a NACK
  i2c: imx-lpi2c: add debug message when i2c peripheral clk doesn't work
