Roel Kluin	7df56c2586	[ARM] pxa: ensure mfp is in correct range in mfp_{read,write} ... Ensure we do not read/write outside array boundaries with a negative index. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>	2009-11-17 00:50:10 +08:00
Daniel Mack	fb60870f63	[ARM] pxa: add MFP_PULL_FLOAT ... There is currently an uncovered case for MFP configuration on PXAs which is selected by setting the PULL_SEL bit but none of the PULL{UP,DOWN}_EN bits. This case is needed to explicitly let pins float, even if the selected alternate function would default to a configuration with a pull resistor enabled.
