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

2012-12-06T22:30:38+00:00

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.

gpio:fix: Proper handling of GPIO subsystem parts at Samsung devices

2012-11-15T12:08:18+00:00

Now proper GPIO parts numbering is handled at Samsung devices.
This fix is necessary for code using GPIO located at other banks
than first.

Test HW:
- Exynos4210 - Trats
- S5PC110 - goni

mx6: use CONFIG_MX6 instead of CONFIG_MX6Q

2012-11-10T07:15:40+00:00

Use CONFIG_MX6 when the particular processor
variant isn't important.

Reserve the use of CONFIG_MX6Q to
specifically test for quad cores variant.

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

2012-10-15T18:54:06+00:00

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.

GPIO: pca953x: fix error reporting

2012-10-08T18:12:07+00:00

Use the standard CMD_RET_* constants to clearly report errors from the
pca953x command. In addition, print error messages when I2C communication
fails.
