* Exynos: Fix ARM Clock frequency calculationChander Kashyap2012-02-12-6/+9
| | | | | | | | | | Earliar ARM clock frequency was calculated by: MOUTAPLL/(DIVAPLL + 1) which is actually returning SCLKAPLL. It is fixed by calculating it as follows: ARMCLK=MOUTCORE / (DIVCORE + 1) / (DIVCORE2 + 1) Signed-off-by: Chander Kashyap <chander.kashyap@linaro.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

* mmc: access mxcmmc from mx31 boardsHelmut Raiger2012-02-12-24/+50
| | | | | | | | | | | | | | | | | 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.

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.

* tegra2: Fix conflicting pinmux for UARTAStephen Warren2012-02-12-0/+12
| | | | | | | | | | | | | | | 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.
