dmaengine: xilinx: dpdma: Add missing dependencies to Kconfig

2021-06-30T12:47:18+00:00

[ Upstream commit 32828b82fb875b06511918b139d3a3cd93d34262 ] The driver depends on both OF and IOMEM support, express those dependencies in Kconfig. This fixes a build failure on S390 reported by the 0day bot.

dmaengine: ALTERA_MSGDMA depends on HAS_IOMEM

2021-06-23T12:42:40+00:00

[ Upstream commit 253697b93c2a1c237d34d3ae326e394aeb0ca7b3 ] When CONFIG_HAS_IOMEM is not set/enabled, certain iomap() family functions [including ioremap(), devm_ioremap(), etc.] are not available. Drivers that use these functions should depend on HAS_IOMEM so that they do not cause build errors. Repairs this build error: s390-linux-ld: drivers/dma/altera-msgdma.o: in function `request_and_map': altera-msgdma.c:(.text+0x14b0): undefined reference to `devm_ioremap' Fixes: a85c6f1b2921 ("dmaengine: Add driver for Altera / Intel mSGDMA IP core") Signed-off-by: Randy Dunlap Reported-by: kernel test robot Cc: Stefan Roese Cc: Vinod Koul Cc: dmaengine@vger.kernel.org Reviewed-by: Stefan Roese Phone: (+49)-8142-66989-51 Fax: (+49)-8142-66989-80 Email: sr@denx.de Link: https://lore.kernel.org/r/20210522021313.16405-2-rdunlap@infradead.org Signed-off-by: Vinod Koul Signed-off-by: Sasha Levin

misc: mic: remove the MIC drivers

2020-10-28T18:12:03+00:00

This patch removes the MIC drivers from the kernel tree since the corresponding devices have been discontinued. Removing the dma and char-misc changes in one patch and merging via the char-misc tree is best to avoid any potential build breakage.

dmaengine: xilinx: dpdma: Add the Xilinx DisplayPort DMA engine driver

2020-07-17T06:07:59+00:00

The ZynqMP DisplayPort subsystem includes a DMA engine called DPDMA with 6 DMa channels (4 for display and 2 for audio). This driver exposes the DPDMA through the dmaengine API, to be used by audio (ALSA) and display (DRM) drivers for the DisplayPort subsystem.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

dmaengine: mmp_tdma: Remove the MMP_SRAM dependency

A generic SRAM will driver for Device Tree enabled platforms will do as well. The non-DT drivers that use mmp_tdma to transfer audio samples to and from the audio SRAM should depend on MMP_SRAM themselves.
