This makes the SPI core and its users access transfers in the SPI message structure as linked list not as an array, as discussed on LKML.
From: David Brownell <dbrownell@users.sourceforge.net>
Updates including doc, bugfixes to the list code, add spi_message_add_tail(). Plus, initialize things _before_ grabbing the locks in some cases (in case it grows more expensive). This also merges some bitbang updates of mine that didn't yet make it into the mm tree.

[PATCH] spi: ads7846 driver
This is a driver for the ADS7846 touchscreen sensor, derived from the corgi_ts and omap_ts drivers. Key differences from those two:
- Uses the new SPI framework (minimalist version) - <linux/spi/ads7846.h> abstracts board-specific touchscreen info - Sysfs attributes for the temperature and voltage sensors - Uses fewer ARM-specific IRQ primitives
The temperature and voltage sensors show up in sysfs like this:
$ pwd /sys/devices/platform/omap-uwire/spi2.0 $ ls bus@ input:event0@ power/ temp1 vbatt driver@ modalias temp0 vaux $ cat modalias ads7846 $ cat temp0 991 $ cat temp1 1177 $
So far only basic testing has been done. There's a fair amount of hardware that uses this sensor, and which also runs Linux, which should eventually be able to use this driver.
One portability note may be of special interest. It turns out that not all SPI controllers are happy issuing requests that do things like "write 8 bit command, read 12 bit response". Most of them seem happy to handle various word sizes, so the issue isn't "12 bit response" but rather "different rx and tx write sizes", despite that being a common MicroWire convention. So this version of the driver no longer reads 12 bit native-endian words; it reads 16-bit big-endian responses, then byteswaps them and shifts the results to discard the noise.

Input: ads7846 - fix integer overflow on Rt calculation [ Upstream commit 820830ec918f6c3dcd77a54a1c6198ab57407916 ] In some rare cases the 32 bit Rt value will overflow if z2 and x is max, z1 is minimal value and x_plate_ohms is relatively high (for example 800 ohm). This would happen on some screen age with low pressure. There are two possible fixes: - make Rt 64bit - reorder calculation to avoid overflow The second variant seems to be preferable, since 64 bit calculation on 32 bit system is a bit more expensive.

Input: ads7846 - use new `delay` structure for SPI transfer delays In a recent change to the SPI subsystem [1], a new `delay` struct was added to replace the `delay_usecs`. This change replaces the current `delay_usecs` with `delay` for this driver. The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure that both `delay_usecs` & `delay` are used (in this order to preserve backwards compatibility).

Input: ads7846 - correct the value got from SPI According to the touch controller spec, SPI return a 16 bit value, only 12 bits are valid, they are bit[14-3]. The value of MISO and MOSI can be configured when SPI is in idle mode. Currently this touch driver assumes the SPI bus sets the MOSI and MISO in low level when SPI bus is in idle mode. So the bit[15] of the value got from SPI bus is always 0. But when SPI bus congfigures the MOSI and MISO in high level during the SPI idle mode, the bit[15] of the value get from SPI is always 1. If bit[15] is not masked, we may get the wrong value. Mask the invalid bit to make sure the correct value gets returned. Regardless of the SPI bus idle configuration.

Input: ads7846 - use PTR_ERR_OR_ZERO() The PTR_ERR_OR_ZERO() helper function checks if a pointer contains an errno code and returns it or return 0 if that's not the case. Use the helper instead of open coding the same logic in the driver. This was found with make coccicheck that complains with the following warning: drivers/input/touchscreen/ads7846.c:532:1-3: WARNING: PTR_ERR_OR_ZERO can be used Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

Input: ads7846 - change name of wakeup property to "wakeup-source" Wakeup property of device is not Linux-specific, it describes intended system behavior regardless of the OS being used. Therefore let's drop "linux," prefix, and, while at it, use the same name as I2C bus does: "wakeup-source". We keep parsing old name to keep compatibility with old DTSes.
