The usbtouchscreen module implements a driver for the TSC-10 DM USB
touchscreen controllers, but assumes a 2-byte response for the
CMD_RESET and CMD_RATE commands, when they can be only a single byte
when no EEPROM is connected.

The driver worked with an earlier controller revision, but new
revisions of the controller fail.

It seems the problem is that the early controller had the
SEL4/EEPROM-CS pin high, but the new controller has it down, making
the response different.

Without the fix, the controller would answer the single byte 0x06
(ACK), making the init fail with -ENODEV because buf[1] is 0xFF (as
initialized before).

As the single byte is the only thing we need to check it was ok, there
is no need to verify the second byte.

The [0x15 0x01] case is the NAK [0x15] response for when there is no
data in the EEPROM [bit-0 of second byte set], so I let that be, as I
don't have any controller with an EEPROM.

With this patch, both the earlier and latest controller work the same.

Note: This was previously submited as BUG #11961 [1] on the bugzilla
tracker, but rebased to version 2.6.27.4 and with unnecessary comments
and printk's removed.

as deprecated.

This unbreaks the legacy configs in {corgi,spitz}_defconfig, however, SPI

with integrated backlight support are recommended.

We had a report a while back that the ads7846 driver had some issues
when used with DMA-based SPI controllers (like atmel_spi) on systems
where main memory is not DMA-coherent (most non-x86 boards). Allocate
memory potentially used for DMA separately to avoid cache line issues.

Since this chip supports more features than only touchscreen,
it was necessary to prepare it for feature addition. The
previous functionality is preserved by applying this patch.

Currently the support for each WM97xx touchscreen model is compiled out
by default, meaning that the default configuration when the driver is
built is for it to support no hardware.  This is suboptimal and leads to
problems like distribution kernels shipping a non-functional driver.

to reflect this.

The chip phy_init() function must be called before the dig_enable() function
but dig_enable() is called when the device is opened and we only call
phy_init() after having reigstered the device, meaning the two can race.
Fix this by doing the phy_init() before we register the input device.
