The patch titled
omap_uwire: SPI_CPHA mode bugfix
has been removed from the -mm tree. Its filename was
omap_uwire-spi_cpha-mode-bugfix.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: omap_uwire: SPI_CPHA mode bugfix
From: Imre Deak <imre.deak@xxxxxxxxxxxxx>
The omap_uwire controller driver handles SPI_CPHA incorrectly;
It should mean:
CPHA=0 ... sample at leading edge of clock
CPHA=1 ... sample at trailing edge of clock
This bug has been masked by inverse bugs in layered drivers;
and was uncovered by running some of them on non-OMAP hardware.
