soc: imx: Move power-domain drivers to the genpd dir

2023-07-11T13:30:09+00:00

To simplify with maintenance let's move the imx power-domain drivers to the new genpd directory. Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS.

soc: imx: gpc: fix power up sequencing

2020-03-16T03:39:02+00:00

Currently we wait only until the PGC inverts the isolation setting before disabling the peripheral clocks. This doesn't ensure that the reset is properly propagated through the peripheral devices in the power domain. Wait until the PGC signals that the power up request is done and wait a bit for resets to propagate before disabling the clocks. Signed-off-by: Lucas Stach Signed-off-by: Shawn Guo
