2018-06-18ARM: pxa: add dma slave mapRobert Jarzmik1-1/+37
In order to remove the specific knowledge of the dma mapping from PXA drivers, add a default slave map for pxa architectures. This is the first step, and once all drivers are converted, pxad_filter_fn() will be made static, and the DMA resources removed from device.c.

2016-11-05ARM: pxa: fix pxa25x interrupt initRobert Jarzmik1-1/+1
In the device-tree case, the root interrupt controller cannot be accessed through the 6th coprocessor, contrary to pxa27x and pxa3xx architectures. Fix it to behave as in non-devicetree builds.

2016-08-09ARM: pxa: remove platform dma codeRobert Jarzmik1-3/+0
As the last pxa related driver was converted to dmaengine, it's time to kill the legacy dma code, which is not used anymore. This finishes the pxa dmaengine transition. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>

2015-07-18ARM: pxa: transition to dmaengine phase 1Robert Jarzmik1-0/+1
In order to slowly transition pxa to dmaengine, the legacy code will now rely on dmaengine to request a channel. This implies that PXA architecture selects DMADEVICES and PXA_DMA, which is not pretty. Yet it enables PXA drivers to be ported one by one, with part of them using dmaengine, and the other part using the legacy code. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>
2015-05-13ARM: pxa: Transition pxa25x, pxa27x, pxa3xx to clk frameworkRobert Jarzmik1-1/+0
Transition the PXA25x, PXA27x and PXA3xx CPUs to the clock framework. This transition still enables legacy platforms to run without device tree as before, ie relying on platform data encoded in board specific files. This is the last step of clock framework transition for pxa platforms. It was tested on lubbock (pxa25x), mioa701 (pxa27x) and zylonite (pxa3xx).

2015-05-13ARM: pxa: Transition pxa25x and pxa27x to clk frameworkRobert Jarzmik1-182/+0
Transition the PXA25x and PXA27x CPUs to the clock framework. This transition still enables legacy platforms to run without device tree as before, ie relying on platform data encoded in board specific files. The transition breaks the previous clocks activation of pin control (gpio11 and gpio12). Machine files should be amended to take that into account. This is the last step of clock framework transition for pxa25x and pxa27x, leaving only pxa3xx for further work.

2009-12-01[ARM] pxa: allow platforms to control which uarts are registeredRussell King1-6/+1
For some platforms, it is inappropriate to register all PXA UARTs. In some cases, the UARTs may not be used, and in others we may want to avoid registering the UARTs to allow other drivers (eg, FICP) to make use of the UART. In addition, a while back there was a request to be able to pass platform data to the UART driver. This patch enables all of this by providing functions platforms can call to register each individual UART.
