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.
