* crypto: mediatek - remove obsolete driverVic Wu2021-01-031-586/+0
| | | | | | | | | The crypto mediatek driver has been replaced by the inside-secure driver now. Remove this driver to avoid having duplicate drivers. Signed-off-by: Vic Wu <vic.wu@mediatek.com> Acked-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: drivers - Remove dev_err() usage after platform_get_irq()Stephen Boyd2019-08-091-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

* cross-tree: phase out dma_zalloc_coherent()Luis Chamberlain2019-01-081-8/+8
| | | | | | | | | | | | | | | | | | | 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) Suggested-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Luis Chamberlain <mcgrof@kernel.org> [hch: re-ran the script on the latest tree] Signed-off-by: Christoph Hellwig <hch@lst.de>
* headers: separate linux/mod_devicetable.h from linux/platform_device.hRandy Dunlap2018-07-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | At over 4000 #includes, <linux/platform_device.h> is the 9th most #included header file in the Linux kernel. It does not need <linux/mod_devicetable.h>, so drop that header and explicitly add <linux/mod_devicetable.h> to source files that need it. 4146 #include <linux/platform_device.h> After this patch, there are 225 files that use <linux/mod_devicetable.h>, for a reduction of around 3900 times that <linux/mod_devicetable.h> does not have to be read & parsed. 225 #include <linux/mod_devicetable.h> This patch was build-tested on 20 different arch-es. It also makes these drivers SubmitChecklist#1 compliant.

| | | | | | | | This patch removes redundant clock setting for 'clk_ethif', which is the parent of 'clk_cryp'. Hence, we just need to handle its child. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: mediatek - simplify descriptor ring managementRyder Lee2017-03-161-0/+3
| | | | | | | | | | | | This patch replaces cmd_pos/res_pos with pointer cmd_next/res_next. In old code, we must to add one to shift ring to the next segment, and then use this value to caculate current offset from ring base for each DMA operation. Now these pointers helps us to simplify flow, so we just need to move pointers and check the boundaries of ring.
