Staging driver fixes for 4.12-rc2
Here are a number of staging driver fixes for 4.12-rc2 Most of them are typec driver fixes found by reviewers and users of the code. There are also some removals of files no longer needed in the tree due to the ion driver rewrite in 4.12-rc1, as well as some wifi driver fixes. And to round it out, a MAINTAINERS file update. All have been in linux-next with no reported issues.

Hi6220 SoC ION
|
||||
===================================================================
|
||||
Required properties:
|
||||
- compatible : "hisilicon,hi6220-ion"
|
||||
- list of the ION heaps
|
||||
- heap name : maybe heap_sys_user@0
|
||||
- heap id : id should be unique in the system.
|
||||
- heap base : base ddr address of the heap,0 means that
|
||||
it is dynamic.
|
||||
- heap size : memory size and 0 means it is dynamic.
|
||||
- heap type : the heap type of the heap, please also
|
||||
see the define in ion.h(drivers/staging/android/uapi/ion.h)
|
||||
-------------------------------------------------------------------
|
||||
Example:
|
||||
hi6220-ion {
|
||||
compatible = "hisilicon,hi6220-ion";
|
||||
heap_sys_user@0 {
|
||||
heap-name = "sys_user";
|
||||
heap-id = <0x0>;
|
||||
heap-base = <0x0>;
|
||||
heap-size = <0x0>;
|
||||
heap-type = "ion_system";
|
||||
};
|
||||
heap_sys_contig@0 {
|
||||
heap-name = "sys_contig";
|
||||
heap-id = <0x1>;
|
||||
heap-base = <0x0>;
|
||||
heap-size = <0x0>;
|
||||
heap-type = "ion_system_contig";
|
||||
};

Ion Memory Manager
|
||||
|
||||
Ion is a memory manager that allows for sharing of buffers via dma-buf.
|
||||
Ion allows for different types of allocation via an abstraction called
|
||||
a 'heap'. A heap represents a specific type of memory. Each heap has
|
||||
a different type. There can be multiple instances of the same heap
|
||||
type.
|
||||
|
||||
Specific heap instances are tied to heap IDs. Heap IDs are not to be specified
|
||||
in the devicetree.
|
||||
|
||||
Required properties for Ion
|
||||
|
||||
- compatible: "linux,ion" PLUS a compatible property for the device
|
||||
|
||||
All child nodes of a linux,ion node are interpreted as heaps
|
||||
|
||||
required properties for heaps
|
||||
|
||||
- compatible: compatible string for a heap type PLUS a compatible property
|
||||
for the specific instance of the heap. Current heap types
|
||||
-- linux,ion-heap-system
|
||||
-- linux,ion-heap-system-contig
|
||||
-- linux,ion-heap-carveout
|
||||
-- linux,ion-heap-chunk
|
||||
-- linux,ion-heap-dma
|
||||
-- linux,ion-heap-custom
|
||||
|
||||
Optional properties
|
||||
- memory-region: A phandle to a memory region. Required for DMA heap type
|
||||
(see reserved-memory.txt for details on the reservation)
|
||||
|
||||
Example:
|
||||
|
||||
ion {
|
||||
compatbile = "hisilicon,ion", "linux,ion";
|
||||
|
||||
ion-system-heap {
