[PATCH 0/3] GPCv2 support for i.MX8MQ

[PATCH 0/3] GPCv2 support for i.MX8MQ

[Andrey Smirnov]

Everyone:

This series contains changes I made to add support for i.MX8MQ to
GPCv2 driver in order to enable support of PCIE IP block on i.MX8MQ
SoCs (full tree can be found at [github-v0]). This series is _very_
preliminary and by no means is ready for inclusion (it also has some
unmet dependencies).  However is should be in OK enough shape to get
some early feedback on, which is the intent of this submission.

All other feedback is appreciated as well!

Thank you,
Andrey Smirnov

[PATCH 2/3] soc: imx: gpcv2: Make regmap access table variant specific.

[Andrey Smirnov]

Move regmap access table to be a part of struct imx_pgc_domain_data in
order to allow supporting multiple GPCv2 variants.

[PATCH 3/3] soc: imx: gpcv2: Add support for i.MX8MQ

[Andrey Smirnov]

GPCv2 IP block found on i.MX7D can also be found on i.MX8MQ. Add the
code needed to support the latter as well as the former.
