Merge tag 'imx-drivers-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/drivers

i.MX drivers change for 4.21:
 - A series from Aisheng that improves SCU power domain bindings by
   defining '#power-domain-cells' as 1, and adds i.MX8 SCU power domain
   driver support on top of it.
 - A series from Lucas that updates gpcv2 driver for scalability and
   adds i.MX8MQ support into the driver.
 - Increase gpc driver GPC_CLK_MAX definition to 7, as DISPLAY power
   domain on imx6sx has 7 clocks.

*
* Implementation of the SCU based Power Domains
*
* NOTE: a better implementation suggested by Ulf Hansson is using a
* single global power domain and implement the ->attach|detach_dev()
* callback for the genpd and use the regular of_genpd_add_provider_simple().
* From within the ->attach_dev(), we could get the OF node for
* the device that is being attached and then parse the power-domain
* cell containing the "resource id" and store that in the per device
* struct generic_pm_domain_data (we have void pointer there for
* storing these kind of things).
*
* Additionally, we need to implement the ->stop() and ->start()
* callbacks of genpd, which is where you "power on/off" devices,
* rather than using the above ->power_on|off() callbacks.
*
* However, there're two known issues:
* 1. The ->attach_dev() of power domain infrastructure still does
* not support multi domains case as the struct device *dev passed
* in is a virtual PD device, it does not help for parsing the real
* device resource id from device tree, so it's unware of which
* real sub power domain of device should be attached.
*
* The framework needs some proper extension to support multi power
* domain cases.
*
* 2. It also breaks most of current drivers as the driver probe sequence
* behavior changed if removing ->power_on|off() callback and use
* ->start() and ->stop() instead. genpd_dev_pm_attach will only power
* up the domain and attach device, but will not call .start() which
* relies on device runtime pm. That means the device power is still
* not up before running driver probe function. For SCU enabled
* platforms, all device drivers accessing registers/clock without power
* domain enabled will trigger a HW access error. That means we need fix
* most drivers probe sequence with proper runtime pm.
*
* In summary, we need fix above two issue before being able to switch to
* the "single global power domain" way.
