+Subject: [PATCH 1/1] Add gpio_mouse board setup to atstk1000 board
+
+This patch adds a gpio_mouse_platform_data to the atstk1000 board code and
+registers a gpio_mouse platform_device. This will enable a GPIO mouse on header
+J1 on GPIO of the ATSTK1000 development kit. The board code is enabled/disabled
+in menuconfig.
+
+By connecting J1 (GPIO) to J25 (SWITCH) you can use the following keys to
+simulate a mouse:
+
+SW0: right
+SW1: down
+SW2: up
+SW3: left
+SW5: right button
+SW6: middle button
+SW7: left button

+From: Haavard Skinnemoen <hskinnemoen@atmel.com>
+Subject: [PATCH 2/2] atmel_mci: Fix two subtle but deadly races
+
+This patch fixes two possible races in the atmel_mci driver, at least
+one of which may cause card probing to fail.
+
+The first one may happen if a command fails and the next command is
+queued before the controller is ready to accept a new one. Fix this by
+not enabling error interrupts for commands and instead do any error
+handling when the CMDRDY bit has been set.
+
+The second one may happen after a successful read data transfer where
+then next command is queued after the DMA transfer is complete, but
+before the whole data transfer from the card is complete (i.e. the
+card is still sending CRC, for example.) Fix this by waiting for the
+NOTBUSY bit to be set before considering the request to be done. This
+will also ensure that we actually see any CRC failures before
+completing the request.
