2012-02-12OMAP4: clock-common: Move the usb dppl configuration to new funcGovindraj.R
usb dpll configuration is done only part of non-essential dppl configuration however if CONFIG_USB_EHCI_OMAP is defined we may have to configure usb dpll's for proper functioning of usb modules. So move the usb dppl configuration to a new func. and utilise the same during essential dpll configuration.

This patch modifies mxcmmc.c to be used not only by i.MX27 but also by i.MX31 boards. Both use the same SD controller, but have different clock set-ups. The i.MX27 imx_get_XXXclock functions are made static to generic.c and a public mxc_get_clock() function is provided. Pins, base address and prototypes for an i.MX31 specific board_init_mmc() are provided. Some of the i.MX27 clock getters are unused and marked as such to avoid warnings (./MAKEALL -s mx27), but the code was left in for future use.

2012-02-12OMAP3: Correct get_sdr_cs_offset maskTom Rini
The function get_sdr_cs_offset reads the CS_CFG register in the SDRC to determine where CS1 is mapped to. make_cs1_contiguous() will set CS1 to follow after CS0. The CS_CFG register has values in bits 9:8 and 3:0 but we had erroneously been testing 5:4 and 3:0 resulting in incorrect offsets on platforms with less than 128MB as 3:0 describe 128MB hunks and 9:8 describe 32MB offsets after the 128MB hunk.

2012-02-12tegra2: Fix conflicting pinmux for UARTAStephen Warren
Tegra appears to boot with function UARTA pre-selected on mux group SDB. If two mux groups are both set to the same function, it's unclear which group's pins drive the RX signals into the HW module. For UARTA, SDB certainly overrides group IRTX in practice. To solve this, configure some alternative function on SDB to avoid the conflict. Also, tri-state the group to avoid driving any signal onto it until we know what's connected.
