* gpio/gpio-stmpe: Fix the value returned by _get_value routineBhupesh Sharma2012-03-121-1/+1
| | | | | | | | | | | | | | | | | | | The present _get_value routine returns the contents of the GPIO Monitor Pin Status Register(GPMR) starting from the bit whose value is requested to BIT 0 (irrelevant bits are replace by 0). For e.g. if we request the value of GPIO 6 in the earlier implementation the value returned is: BIT6 followed by 6 0's whereas it should just return BIT6. This patch addresses the same.

* gpio: Add support for stmpe variant 801Viresh Kumar2012-01-091-3/+22
| | | | | | | | | | STMPE801 is a GPIO expander. GPIO registers for 801 are slightly different from other variants. This patch adds support for STMPE801 in stmpe gpio driver.

* gpio: reorganize driversGrant Likely2011-06-061-0/+404
Sort the gpio makefile and enforce the naming convention gpio-*.c for gpio drivers. v2: cleaned up filenames in Kconfig and comment blocks v3: fixup use of BASIC_MMIO to GENERIC_GPIO for mxc Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
