[ARM] pxa: add basic support for HP iPAQ hx4700 PDAs
This includes - IrDA (pxafixp_ir), - Buttons (gpio-keys), - ASIC3 IRQ/GPIOs (asic3), - EGPIOs (htc-egpio), - ATI Imageon w3220 framebuffer (w100fb), - Backlight (pwm-backlight), - StrataFlash (physmap), - Battery monitor (ds1wm,w1_ds2760,ds2760_battery) - USB gadget support (pxa27x_udc,gpio_vbus). - bq24022 battery charger (pda_power,bq24022) - TSC2046 touchscreen (ads7846) Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Eric Miao <eric.miao@marvell.com>
