mfd: Add LPC driver for Intel ICH chipsets This driver currently creates resources for use by a forthcoming ICH chipset GPIO driver. It could be expanded to create the resources for converting the esb2rom (mtd) and iTCO_wdt (wdt), and potentially more, drivers to use the mfd model.

mfd: lpc_ich: Add support for SPI serial flash host controller Many Intel CPUs including Haswell, Broadwell and Baytrail have SPI serial flash host controller as part of the LPC device. This will populate an MFD cell suitable for the SPI host controller driver if we know that the LPC device has one.

enum intel_spi_type spi_type;
gpio: gpio-ich: Share ownership of GPIO groups The ICH chips have their GPIO pins organized in 2 or 3 independent groups of 32 GPIO pins. It can happen that the ACPI BIOS wants to make use of pins in one group, preventing the OS to access these. This does not prevent the OS from accessing the other group(s). This is the case for example on my Asus Z8NA-D6 board. The ACPI BIOS wants to control GPIO 18 (group 1), while I (the OS) need to control GPIO 52 and 53 (group 2) for SMBus multiplexing. So instead of checking for ACPI resource conflict on the whole I/O range, check on a per-group basis, and consider it a success if at least one of the groups is available for the OS to use.
