With the generic DMA device tree helper supported by mxs-dma driver, client devices only need to call dma_request_slave_channel() for requesting a DMA channel from dmaengine.

Since mxs is a DT only platform now, along with the changes, the non-DT case handling in probe function also gets removed.

Update mxs-dma driver to adopt generic DMA device tree binding. It calls of_dma_controller_register() with mxs specific of_dma_xlate to get the generic DMA device tree helper support. Then DMA clients only need to call dma_request_slave_channel() for requesting a DMA channel from dmaengine. The existing way of requesting channel, clients directly call dma_request_channel(), still work there, and will be removed after all mxs-dma clients get converted to generic DMA device tree helper.

Add generic DMA device tree binding for mxs-dma. The changes include: * Add channel interrupts into DMA controller nodes * Add properties '#dma-cells' and 'dma-channels' for DMA controller nodes * And properties 'dmas' and 'dma-names' for DMA client nodes * Update mxs-dma device tree binding doc Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Reviewed-by: Arnd Bergmann <arnd@arndb.de>

Some pins on the i.mx23 and i.mx28 are missing pull-ups, document that oddity because it was difficult to know the expected behaviour. Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

None of mxsfb users uses mxsfb_platform_data now. Let's remove it from mxsfb driver. As the result, include/linux/mxsfb.h gets deleted with a few macros moved into mxsfb.c. Along with the change, the typo "FAILING" in macro name is fixed to be "FALLING". Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

There is no in-tree mxsfb users using mxsfb_platform_data dotclk_delay. Let's remove it from mxsfb_platform_data to ease full device tree adoption of mxsfb driver. If later we have platform/board need to configure this parameter, we can add it into device tree bindings. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

There is no in-tree users of mxsfb_platform_data fb_phys/fb_size. With CMA support in the kernel, there is no real need for platform to reserve memory and pass address and size into driver via platform_data. So let's remove fb_phys/fb_size from mxsfb_platform_data to ease full device tree adoption. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

Put the clock to the devicetree, so the driver can take care of it later. Then, we don't have to do the enabling as a workaround in board init.

When the optional clk_ptp is absent, we can just set it to NULL, and clk API will just handle it gracefully. It saves us from checking clk_ptp whenever calling into clk API. Also since clk_ptp is optional, the "ret" variable shouldn't be set in case that the clock is absent. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: David S. Miller <davem@davemloft.net>
