Subject: [PATCH v2 0/8] RZN1 DMA support
Date: Tue, 22 Feb 2022 11:34:29 +0100 [thread overview]
Message-ID: <20220222103437.194779-1-miquel.raynal@bootlin.com> (raw)
Hello,
Here is a first series bringing DMA support to RZN1 platforms. I'm not a
DMA expert at all so criticism is welcome.
Soon a second series will come with changes made to the UART controller
driver, in order to interact with the RZN1 DMA controller.
Cheers,
Miquèl
Changes in v2:
* Clarified that the 'fix' regarding non aligned reads would only apply
to the DEV_TO_MEM case.
* Fix the DMA controller compatible string (copy-paste error).
* s/syscon/sysctrl/ as advised by Geert.
* Disabled irqs when taking the spinlock from the clocks driver.
* Moved the DMAMUX offset inside the driver.
* Removed extra commas.
* Improved the style as suggested by Andy.
* Removed a dupplicated check against the device node presence.
* Reduced the number of lines of code by using dev_err_probe().
* Created a Kconfig symbol for DMAMUX to fix the two robot reports
received and be sure there was no useless overhead with other
platforms.
