Wed Sep 26 13:52:24 UTC 2018


This patchset is to upstream i.MX8QXP and mek board support, with some
drivers update to support i.MX8QXP. The information about the processor
could be found
https://www.nxp.com/products/processors-and-microcontrollers/applications-processors/i.mx-applications-processors/i.mx-8-processors/i.mx-8x-family-arm-cortex-a35-3d-graphics-4k-video-dsp-error-correcting-code-on-ddr:i.MX8X

The architecture of i.MX8QXP is different from i.MX6/7/8M, inside i.MX8QXP,
there is a dedicated processor(SCU) used for power/clock/pin/
pad/resource management/thermal and etc.


V5:
Addressed Lothar Waßmann's comments for patch 24 and 32.
Rebased on master.

V4:
Add reviewed tag from Anatolij Gustschin
Addressed comments from Anatolig for patch "misc: add i.MX8 misc driver"
Addressed comments from Anatolig for patch "misc: imx8: add scfw api impementation"
 Merged the files into one
 Moved one error handle to patch 4
Moved patch "arm: global_data: add scu_dev for i.MX8" to patch 7
For Fabio's comments to imx-mkimage, I'll start the porting work, but needs
more time, it will be not be in this patchset.

V3:

patch 7: use CONFIG_IMX8
patch 29: use CONFIG_IMX8
patch 32: Added README with scfw_tcm.bin link added
misc: remove sc_rpc_msg_t typedef, use struct sc_rpc_msg_s in patchset.

V2:
In this V2 patchset, the SCFW API is replaced by uclass driver
implementation, but the api name is not changed from scfw api.
The related macro definitions are kept in different api.h file
following SCFW API file structure.

Impelemnted scu misc driver to handle the low level communication
between Acore and SCU.
Implemented rm/pm/pad/misc protocol code to invoke misc_call for
different functionality.
The dm clk/pinctrl/power and others will invokde the protocol api
to communicate with SCU.

The arch/arm/mach-imx/imx8/clock.c currently is only a dummy
file to avoid build break for mxc_get_clock.

The i2c patch and common power domain patches are removed
from this patchset.

The imx8 name still kept, this is because NXP marketing
requires to use this name for i.MX branding.
