x86: gpio: Add additional GPIO banks to the ICH6 driver

2012-12-06T22:30:38Z

We can generally trust the ICH to have GPIO Bank 0 (the first 32 pins) in the same place across all versions. This change adds two more banks, for up to 96 GPIOS. BUT: - Not all chipsets have the same number of GPIOs - Not all chipsets have the same number of GPIO banks - Not all chipsets put the additional banks at the same offset from GPIOBASE - There so many chipset variants that it's pretty much impossible to support them all, or even keep track of the new ones. So, although this adds suppport for the additional banks that seem to work for the particular variants of CougarPoint Mobile chipsets that we've tried, there's no chance it will support everything Intel produces. Good luck. Signed-off-by: Bill Richardson Signed-off-by: Simon Glass

Tegra20: Move some include files to arch-tegra for sharing with Tegra30

2012-10-15T18:54:06Z

The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK. Signed-off-by: Tom Warren

GPIO: pca953x: fix error reporting

2012-10-08T18:12:07Z

Use the standard CMD_RET_* constants to clearly report errors from the pca953x command. In addition, print error messages when I2C communication fails. Signed-off-by: Laurence Withers

ARM : Add GPIO Driver and IOMUX definition for S3C2440

2012-10-03T08:50:20Z

It's now possible to use the gpio driver interface for s3c2440. This patch add iomux definitions too. Signed-off-by: Gabriel Huau

Tegra: Change Tegra20 to Tegra in common code, prep for T30

2012-09-10T20:01:24Z

Convert TEGRA20_ defines to either TEGRA_ or NV_PA_ where appropriate. Convert tegra20_ source file and function names to tegra_, also. Upcoming Tegra30 port will use common code/defines/names where possible. Signed-off-by: Tom Warren Acked-by: Stephen Warren

mxc: Make gpio_get_value() use PSR

2012-09-01T12:58:28Z

gpio_get_value() should use PSR like Linux, not DR, because DR does not always reflect the pin state, while PSR does. This is especially useful to detect a short circuit on a GPIO pin configured as output, or to read the level of a pin controlled by a non-GPIO IOMUX function.
