* Input: atmel_mxt_ts - use snprintf for sysfs attribute show methodDaniel Kurtz2011-10-071-6/+15
| | | | | | | | | | | | | | Sysfs attribute show methods are always passed a buffer of length PAGE_SIZE. To keep from overwriting this buffer and causing havoc, use snprintf() to guarantee we never write more than the buffer can hold. In addition, at least for my touchscreen, the number and size of objects was far too big to fit in a single 4K page. Therefore, this patch also trims some redundant framing text to leave more room for actual data.

| | | | | | | | | | | | | | | | | V2 hardware has many variants. This patch adddresses two issues: - some model also has debounce packets, but with a different signature than v3. Now we just check debounce for all v2 hardware. - due to different scanning methods the hardware uses, x and y ranges have to be calculated differently. And for some specific versions, we can just see them as custom-made, so set {x, y} the same values as Windows driver does.

Without this patch Suspend-to-RAM hangs on the boards AP4EVB and Mackerel. The code hangs in the LCDC driver where the software is waiting forever for the hardware to power down. By explicitly associating the HDMI clock with LCDC1 we can make sure the HDMI clock is enabled using Runtime PM whenever the driver is accessing the hardware. This HDMI and LCDC1 dependency is documented in the sh7372 data sheet. Older kernels did work as expected but the recently merged (3.1-rc) 794d78f drivers: sh: late disabling of clocks V2 introduced code to turn off clocks lacking software reference which happens to include the HDMI clock that is needed by LCDC1 to operate as expected.
