firmware: imx: scu-pd: Update comments for single global power domain

2021-03-29T00:59:33Z

Since the introduction of the PM domain support for the scu-pd, the genpd framework has been continuously improved. More preciously, using a single global power domain can quite easily be deployed for imx platforms. To avoid confusions, let's therefore make an update to the comments about the missing pieces.

firmware: imx-dsp: Export functions to request/free channels

2020-11-16T08:33:48Z

In order to save power, we only need to request a channel when the communication with the DSP active. For this we export the following functions: - imx_dsp_request_channel, gets a channel with a given index - imx_dsp_free_channel, frees a channel with a given index Notice that we still request channels at probe to support devices that do not have PM callbacks implemented. More explanations about why requesting a channel has an effect on power savings: - requesting an mailbox channel will call mailbox's startup function. - startup function calls pm_runtime_get_sync which increments device usage count and will keep the device active. Specifically, mailbox clock will be always ON when a mailbox channel is requested. Signed-off-by: Daniel Baluta Reviewed-by: Paul Olaru Signed-off-by: Shawn Guo
