Subject: PATCH: at91_nand rdy_pin fix
Date: Thu, 24 May 2007 00:53:14 +0300 (EEST) [thread overview]
Message-ID: <51303.127.0.0.1.1179957194.squirrel@localhost> (raw)
Hello,
The patch below fixes nand driver for AT91 boards which do not have NAND R/B signal
connected to gpio (rdy_pin is not connected).
Patch is against 2.6.22-rc1 + corresponding at91 patch from maxim.org.za
Best regards, Ivan
