x86: gpio: Add GPIO driver for Intel ICH6 and later. Implement <asm-generic/gpio.h> functions for Intel ICH6 and later. Only GPIOs 0-31 are handled by this code. Signed-off-by: Bill Richardson <wfrichar@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org> 2012-10-20 11:44:34 +00:00			`/*`

x86: ivybridge: Add support for early GPIO init When not relying on Coreboot for GPIO init the GPIOs must be set up correctly. This is currently done statically through a rather ugly method. As the GPIOs are figured out they can be moved to the device tree and set up as needed rather than all at the start. In this implementation, board files should call ich_gpio_set_gpio_map() before the GPIO driver is used in order to provide the GPIO information. We use the early PCI interface so that this driver can now be used before relocation. Signed-off-by: Simon Glass <sjg@chromium.org> 2014-11-13 05:42:24 +00:00			`* SPDX-License-Identifier: GPL-2.0`

x86: ich6-gpio: Add Intel Tunnel Creek GPIO support Intel Tunnel Creek GPIO register block is compatible with current ich6-gpio driver, except the offset and content of GPIO block base address register in the LPC PCI configuration space are different. Use u16 instead of u32 to store the 16-bit I/O address of the GPIO registers so that it could support both Ivybridge and Tunnel Creek.

x86: gpio: Correct GPIO setup ordering The Intel GPIO driver can set up the GPIO pin mapping when the first GPIO is probed. However, it assumes that the first GPIO to be probed is in the first GPIO bank. If this is not the case then the init will write to the wrong registers. Fix this. Also add a note that this code is deprecated. We should move to using device tree instead.
