Input: mrst-touchscreen - move out of staging

2010-09-02T02:43:36Z

The driver is in reasonable shape now so let's move it out of staging. Acked-by: Alan Cox Acked-by: Greg Kroah-Hartman Signed-off-by: Dmitry Torokhov

Staging: mrst-touchscreen - simplify en/disable of interrupts for NEC

2010-09-02T02:43:30Z

Use 8 bit update commands instead of a 16 bit unaligned read/write pair which fails after the first few calls; the voodoo in the original doesn't seem to be required with this mechanism. Tested-by: Arjan van de Ven Signed-off-by: Andy Ross Signed-off-by: Alan Cox Signed-off-by: Dmitry Torokhov

Staging: mrst-touchscreen - fix channel allocation

2010-09-02T02:43:22Z

The touch screen driver tries to find a range of free channels (which are an array of bytes), by scanning for the "end of used channel" marker. However it tries to be WAAAAY too smart and does 32 bit logic on 8 bit quantities, and in the process completely gets it wrong (repeatedly read the same register instead of incrementing in the loop, assuming that if any of the 4 bytes in the 32 byte quantity is free, all four are free, returning the channel number divided by 4 rather than the actual first free channel number) On the setting side, the same mistakes are made by and large; changed this to just use the byte SCU write functions.... With these fixes we go from a completely non detected touchscreen to something that appears to completely get detected. (after also fixing the ordering issue that Jacobs patch should solve) Signed-off-by: Arjan van de Ven Signed-off-by: Alan Cox Signed-off-by: Dmitry Torokhov

Staging: mrst-touchscreen - register platform interface

2010-09-02T02:43:15Z

AC: Reworked to merge with upstream input device work from Dmitry et al. Signed-off-by: Alek Du Signed-off-by: Alan Cox Signed-off-by: Dmitry Torokhov

Staging: mrst_touchscreen - more fixes

2010-09-02T02:43:08Z

Changes: - switch to use threaded IRQ - more __devinit/__devexit annotations - rely on input core to remove jitter from events - global pointer removed - NEC/MAXIM/Freescale handling factored out Signed-off-by: Alan Cox Signed-off-by: Dmitry Torokhov

Staging: mrst_touchscreen - clean up input side

2010-09-02T02:43:02Z

Fix most of the stuff that Dmitry pointed out. This leaves the mutex in IRQ and misuse of SPI to sort out. Also fix the build bits so it actually builds in staging - whoops. Signed-off-by: Alan Cox Signed-off-by: Dmitry Torokhov

Staging: mrst-touchscreen: fix dereferencing free memory

2010-06-30T15:18:14Z

I moved the kfree() down a couple lines after the dereference. Signed-off-by: Dan Carpenter Acked-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

Staging: mid: Intel MID touch screen driver

2010-06-04T20:38:51Z

Touchscreen driver used by intel mid devices. Some clean up by Alan Cox. This driver is basically ready for upstreaming properly but is tied wrongly to the SPI layer and needs firmware/SFI changes to fix that. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman
