This reverts commit 175fe6289fcb7e13cb5add2b80cdc0e5e049fb95.
This change isn't needed as the new MU binding is efficient and
can handle messages of any sizes.Signed-off-by: Nitin Garg

The implementation was limiting the size of a message which can be
received to 4 but soem response can be bigger. For example the
response of the 'sc_seco_secvio_config' API is 6 words.This patch removes this limitation relying on the count of word
received instead of the index of the chan.
It does so by duplicating imx_scu_call_rpc as imx_scu_call_big_rpc
in order to cahnge the RX method using imx_scu_big_rx_callback
instead of imx_scu_rx_callback.Signed-off-by: Franck LENORMAND

Export imx_sc_pm_cpu_start for all to avoid build error
Acked-by: Richard Zhu
Signed-off-by: Peng Fan -
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 indexNotice 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

This patch adds the driver to interact with the different
APIs exposed by the SECO using a shared Messaging Unit.The driver exposes some char devices in user space allowing
a user to send message to the SECO and read its response.The driver uses the mailbox framework instead of directly

The i.MX SCU soc driver depends on SCU firmware driver, so it has to
use platform driver model for proper defer probe operation, since
it has no device binding in DT file, a simple platform device is
created together inside the platform driver. To make it more clean,
we can just move the entire SCU soc driver into imx firmware folder
and initialized by i.MX SCU firmware driver.Signed-off-by: Anson Huang
