cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37+00:00

We already need to zero out memory for dma_alloc_coherent(), as such
using dma_zalloc_coherent() is superflous. Phase it out.

This change was generated with the following Coccinelle SmPL patch:

@ replace_dma_zalloc_coherent @
expression dev, size, data, handle, flags;
@@

-dma_zalloc_coherent(dev, size, handle, flags)
+dma_alloc_coherent(dev, size, handle, flags)

headers: separate linux/mod_devicetable.h from linux/platform_device.h

2018-07-07T15:52:26+00:00

At over 4000 #includes,  is the 9th most
#included header file in the Linux kernel.  It does not need
, so drop that header and explicitly add
 to source files that need it.

   4146 #include 

After this patch, there are 225 files that use ,
for a reduction of around 3900 times that 
does not have to be read & parsed.

    225 #include 

This patch was build-tested on 20 different arch-es.

It also makes these drivers SubmitChecklist#1 compliant.

crypto: mediatek - move to generic async completion

2017-11-03T14:11:23+00:00

The mediatek driver starts several async crypto ops and waits for their
completions. Move it over to generic code doing the same.

Currently, empty messages are not supported in GCM mode, hence add
a check to prevent producing incorrect results.

This patch removes redundant clock setting for 'clk_ethif', which is
the parent of 'clk_cryp'. Hence, we just need to handle its child.

crypto: mediatek - make hardware operation flow more efficient

2017-03-16T09:58:57+00:00

This patch refines data structures, which are used to control engine's
data path, to make it more efficient. Hence current change are:

- gathers the broken pieces of structures 'mtk_aes_ct''mtk_aes_tfm'
into struct mtk_aes_info hence avoiding additional DMA-mapping.

- adds 'keymode' in struct mtk_aes_base_ctx. When .setkey() callback is
called, we store keybit setting in keymode. Doing so, there is no need
to check keylen second time in mtk_aes_info_init() / mtk_aes_gcm_info_init().

Besides, this patch also removes unused macro definitions and adds helper
inline function to write security information(key, IV,...) to info->state.
