mxc: Make gpio_get_value() use PSR 2012-09-01T12:58:28+00:00 Benoît Thébaudeau benoit.thebaudeau@advansee.com 2012-08-20T10:55:41+00:00 5dafa4543c399d329c7b01df1afa98437861cac0 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.

ARM: add basic support for the Broadcom BCM2835 SoC 2012-09-01T12:58:21+00:00 Stephen Warren swarren@wwwdotorg.org 2012-08-05T16:07:21+00:00 efad6cf8818620b0d85405df2b810760b62acbb8 This SoC is used in the Raspberry Pi, for example. For more details, see: http://www.broadcom.com/products/BCM2835 http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf. Initial support is enough to boot to a serial console, execute a minimal set of U-Boot commands, download data over a serial port, and boot a Linux kernel. No storage or network drivers are implemented. GPIO driver originally by Vikram Narayanan <vikram186@gmail.com> with many fixes from myself. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
