2010-10-28gpio: Fix stmpe error pathVasiliy Kulikov
Free allocated memory. Call stmpe_disable() if it was enabled. Signed-off-by: Vasiliy Kulikov <segooon@gmail.com> Acked-by: Wolfram Sang <w.sang@pengutronix.de> Acked-by: Rabin Vincent <rabin.vincent@stericsson.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2010-10-28gpio: Handle stmpe-gpio platform data with no gpio baseVirupax Sadashivpetimath
This patch removes the requirement that gpio base be supplied in platform data.

2010-10-28gpio: Add bitmask to block requests to unavailable stmpe GPIOsWolfram Sang
GPIOs on these controller are multi-functional. If you decided to use some of them e.g. as input channels for the ADC, you surely don't want those pins to be reassigned as simple GPIOs (which may be triggered even from userspace via 'export'). Same for the touchscreen controller pins. Since knowledge about the hardware is needed to decide which GPIOs to reserve, let this bitmask be inside platform_data and provide some defines to assist potential users.
