The patch titled
DS1WM: decouple host IRQ and INTR active state settings
has been removed from the -mm tree. Its filename was
ds1wm-decouple-host-irq-and-intr-active-state-settings.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: DS1WM: decouple host IRQ and INTR active state settings
From: Philipp Zabel <[EMAIL PROTECTED]>
The DS1WM driver incorrectly infers the IAS bit (1-wire interrupt active
high) from IRQ settings. There are devices that have IAS=0 but still need
the IRQ to trigger on a rising edge. With this patch, machines with DS1WM
that need IAS=1 have to set .active_high=1 in the ds1wm_platform_data.
