From 1fbece150a230d0ab447cfb2fc4df10fb89f0d8c Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sat, 1 Jul 2006 13:39:55 -0700 Subject: [PATCH] pcmcia: at91_cf update More correct AT91 CF wakeup logic ... only enable/disable the IRQ wakeup capability, not the IRQ itself. That way the we know that the IRQ will be disabled correctly, in suspend/resume logic instead of ARM IRQ code. Most of the pin multiplexing setup has moved to the devices.c setup code.

In that case, inside the alloc_io_space function, conflicts are detected (the function returns 1) for the second function of a multifunction card unless the length of IO address range required is greater than 0x100. The following patch will remove this conflict checking for a PCMCIA function which had not mentioned any specific IO address to be mapped from. The patch is tested for Linux kernel 2.6.15.4 and works fine in the above case and is as suggested by Dave Hinds.

Also, a CIS override autoloaded using the firmware loader may allow for the use of more or less functions in a multifunction card. Therefore, we may need to schedule a call to add this second function later on, or simply remove the other function (it's always the first -valid- function which reaches this codepath).

We replace the hard-coded "chip select 4" with the chip-select value passed via platform_data. The configuration of the EBI memory controller to enable Compact Flash access is now also handled in the platform setup code and not in the driver.
