* ARM: dts: da850-evm: fix read access to SPI flashFabien Parent2017-01-26
| | | | | | | | | | | | | | | | | | | | | | commit 43849785e1079f6606a31cb7fda92d1200849728 upstream. Read access to the SPI flash are broken on da850-evm, i.e. the data read is not what is actually programmed on the flash. According to the datasheet for the M25P64 part present on the da850-evm, if the SPI frequency is higher than 20MHz then the READ command is not usable anymore and only the FAST_READ command can be used to read data. This commit specifies in the DTS that we should use FAST_READ command instead of the READ command.

| * ARM: dts: da850,da850-evm: Add an aemif node and use it for the NANDKarl Beldan2016-08-18
| | | | | | | | | | | | | | | | | | | | | | | | Currently the davinci da8xx boards use the mach-davinci aemif code. Instantiating an aemif node into the DT allows to use the ti-aemif memory driver and is another step to better DT support. This change adds an aemif node in the dtsi while retiring the nand_cs3 node. The NAND is now instantiated in the dts as a subnode of the aemif one along with its pins. Signed-off-by: Karl Beldan <kbeldan@baylibre.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>

| | | | | | | | | | | TI has been using the physical address in DT after the @ in device nodes. The device tree convention is to use the same address that is used for the reg property.

* ARM: DTS: da850: Use the new DT bindings for the eDMA3Peter Ujfalusi2015-12-24
| | | | | | | | | | | | | | | | | | | Switch to use the ti,edma3-tpcc and ti,edma3-tptc binding for the eDMA3. With the new bindings boards can customize and tweak the DMA channel priority to match their needs. With the new binding the memcpy is safe to be used since with the old binding it was not possible for a driver to know which channel is allowed to be used as non HW triggered channel. Using the new binding will allow us to reserve PaRAM slots to be used by the DSP which was not possible before and prevented the da850 boards to be moved to DT only. Note that the DMA memcpy is disabled, it can be enabled by reserving channels for memcpy by adding the following property to the edma node: ti,edma-memcpy-channels = <20 21>; /* Reserving channel 20 and 21 for memcpy */ Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Tested-by: Sushaanth Srirangapathi <sushaanth.s@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
