2006-02-15Input: ads7846 - assorted updatesDavid Brownell1-24/+44
This updates the ads7846 touchscreen driver: - to allow faster clocking (this driver doesn't push sample rates); - bugfixes the conversion of spi_transfer to lists; - some dma-unsafe command buffers are fixed.

2006-01-19[ARM] Convert request_irq+set_irq_type to request_irq with SA_TRIGGERRussell King1-6/+3
There's no need to have request_irq followed by set_irq_type. Just use request_irq with the appropriate SA_TRIGGER flags. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-01-16[PATCH] sh: consolidate hp620/hp680/hp690 targets into hp6xxPaul Mundt1-1/+1
Most of the reasons for keeping these separate before was due to hp690 discontig, and since we have a workaround for that now (abusing some shadow space so everything is magically contiguous), there's no reason to keep the targets separate.

2006-01-13[PATCH] spi: use linked lists rather than an arrayVitaly Wool1-4/+8
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.

2006-01-13[PATCH] spi: ads7836 uses spi_driverDavid Brownell1-42/+42

2006-01-13[PATCH] spi: ads7846 driverDavid Brownell3-0/+635
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.

2005-11-09[DRIVER MODEL] Convert platform drivers to use struct platform_driverRussell King1-16/+16

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King1-20/+18
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

2005-09-13[PATCH] SharpSL: Abstract c7x0 specifics from Corgi Touchscreen driverRichard Purdie2-31/+45
Separate out the Sharp Zaurus c7x0 series specific code from the Corgi Touchscreen driver. Use the new functions in corgi_lcd.c via sharpsl.h for hsync handling and pass the IRQ as a platform device resource. Move a function prototype into the w100fb header file where it belongs. This enables the driver to be used by the Zaurus cxx00 series.

This patch moves the platform specific Sharp SL-C7x0 LCD code from the w100fb driver into a more appropriate place and updates the Corgi code to match the new w100fb driver. It also updates the corgi touchscreen code to match the new simplified interface available from w100fb.

2005-09-07[PATCH] Corgi Touchscreen: Allow the driver to share the PMURichard Purdie1-6/+9

2005-04-16Linux-2.6.12-rc2Linus Torvalds9-0/+2115
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
