MXS-based SoCs implement gpio support in block PINCTRL.
Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Changes for v5:
- Leave PIN2IRQ set when disabling gpio IRQ to avoid
losting interrupt
Changes for v3:
- include/mach/gpio.h: remove the inclusion of hardware.h
- gpio.c: change inclusion of hardware.h to mx23.h plus mx28.h
- Remove spinlock totally since SET/CLE can be used in all the
gpio register access
Changes for v2:
- Create arch/arm/mach-mxs/gpio.h to accommodate stuff private for mach-mxs
- Use GPIO_INT_LEV_MASK and GPIO_INT_POL_MASK instead of constant
- Remove both edges IRQ support which is not needed
- Use SET and CLR register of PINCTRL_DOE in _set_gpio_direction()
- Use pr_info over printk(KERN_INFO)

MXS-based SoCs implements iomux functions in block PINCTRL.
Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
---
Changes for v5:
- Change iomux_cfg_t from u64 to u16
- Add namespace MXS_ to shift, mask, and pad definitions
- Use SET/CLR register for 1 bit setting
- Get "if" and "{" at the same line
- Remove space in middle of tabs
- Change "setups" to "configures" in comments
Changes for v3:
- Change iomux_cfg_t to u64 to facilitate adding platform specific
pad_ctrl settings to an existing pad definition
- Change inclusion of hardware.h to mxs.h
- Get iomux_base a hard-assignment in mxs_iomux_setup_pad(), since
mx23 and mx28 share the common pinctrl base adress and it's only
used in mxs_iomux_setup_pad().
- Remove EXPORT_SYMBOL and the static of mxs_iomux_setup_pad()
Changes for v2:
- Define iomux_cfg_t as u64
- Turn mxs_iomux_setup_pad() into a static function
- Fix a bug in mxs_iomux_setup_pad(), muxsel starts at offset 0x100 than 0 of pinctrl block.

From: Shawn Guo @ 2010-12-10 8:06 UTC (permalink / raw)
To: linux-arm-kernel
Add clock for MXS-based SoCs, MX23 and MX28.
Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
---
Changes for v5
- Fix PARENT_RATE_SHIFT from left to right
Changes for v3:
- Fix freq overflow in clock-mx23.c as well
- Fix the overflow using SH_DIV and shifting 8 bits
- Remove the inclusion of hardware.h and include mx23.h/mx28.h
Changes for v2:
- Shift pll0_clock freq 480MHz in children freq computation to avoid overflow
- Fix fec_clk to stand for fec clock than IEEE1588 time clock
- Add pll2_clk into clock lookups, as it's fec phy clock and needs to be on before reset phy
