2022-01-24misc: mark write buffer constJohn Keeping
The write operation in misc_ops already takes a "const void *" buffer, but misc_write() takes a mutable "void *". There's no reason for this, so make misc_write() consistent with the standard write() prototype. Signed-off-by: John Keeping <john@metanate.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2019-02-09misc: Allow child devicesSimon Glass
Allow misc devices to have children, so that we can use this uclass for cases where a child device (e.g. I2S) needs to access a misc driver for transferring data. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2016-08-12misc: add "call" uclass opStephen Warren
The call op requests that the callee pass a message to the underlying HW or device, wait for a response, and then pass back the response error code and message to the callee. It is useful for drivers that represent some kind of messaging or IPC channel to a remote device. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>
