[v2,00/17] Add BLK_CTRL support for i.MX8MP

Message

Abel Vesa Aug. 14, 2020, 12:09 p.m. UTC

The BLK_CTRL according to HW design is basically the wrapper of the entire
function specific group of IPs and holds GPRs that usually cannot be placed
into one specific IP from that group. Some of these GPRs are used to control
some clocks, other some resets, others some very specific function that does
not fit into clocks or resets. Since the clocks are registered using the i.MX
clock subsystem API, the driver is placed into the clock subsystem, but it
also registers the resets. For the other functionalities that other GPRs might
have, the syscon is used.

Changes since v1:
 * implemented the runtime pm in blk_ctrl as discussed with Philipp Zabel on
v1 thread
 * changed the blk-ctl to clock-controller in the dts and doc
 * fixed the yaml doc
 * removed the power-domains properties since the power-domains driver
is not yet upstream for i.MX8MP.
