eaf9393bb7 ARM: OMAP2: Fix tusb6010 init error and compilation warning
Fix "tusb6010 init error 5, -19" and compilation warning from function
tusb6010_platform_retime "warning: 'sysclk_ps' is used uninitialized in this
function".

I suppose commit c094ba34b8f780885d029ce3c2715a194b780e5d was meant to test
for zero fclk_ps instead of sysclk_ps.

d94a2eddf5 ARM: OMAP2: possible division by 0
In linus' git tree the functions can be found at:
vi arch/arm/mach-omap2/usb-tusb6010.c +200	- tusb6010_platform_retime()
vi arch/arm/mach-omap2/gpmc.c +94		- gpmc_get_fclk_period()
vi arch/arm/mach-omap2/usb-tusb6010.c +53	- tusb_set_async_mode()
vi arch/arm/mach-omap2/usb-tusb6010.c +111	- tusb_set_sync_mode()

is -ENODEV appropriate when sysclk_ps == 0?

This was found by code analysis, please review.
------------------------------>8-------------8<---------------------------------
gpmc_get_fclk_period() may return 0 when gpmc_l3_clk is not enabled. This is
not checked in tusb6010_platform_retime() nor in tusb_set_async_mode() it
seems. In tusb_set_sync_mode() this may result in a division by zero.

40e3925ba1 ARM: OMAP: switch to gpio_direction_input
More switchover to the cross-platform GPIO interface:
use gpio_direction_input(), not an OMAP-specific call.

ca6d1b1333 usb: musb: pass configuration specifics via pdata
Use platform_data to pass musb configuration-specific
details to musb driver.

This patch will prevent that other platforms selecting
HAVE_CLK and enabling musb won't break tree building.

The other parts of it will come when linux-omap merge
up more omap2/3 board-files.
