Tegra has implemented an unnecessary wrapper over tegra_update_cpu_speed(), i.e.
tegra_target(), which wasn't doing anything apart of calling
tegra_update_cpu_speed(). Get rid of that and use tegra_target() directly.

Hi,
My board is using Trustzone and running kernel is non-secure mode.
But setup function of PL310 driver is only for secure mode kernel.
What about adding an entry for non-secure mode setup function?
I'm sorry for my poor code but I just wanna say what I need .

Hi,
I'm looking to use roundup_pow_of_two() (actually, order_base_2())
from , but it seems that it only supports 64-bit integers
if your toolchain uses a 64-bit 'unsigned long' type. This is strange,
considering that ilog2() is explicitly designed for 32-bit or 64-bit
compatibility.

Currently the Tegra1x4 clock init code hard-codes the mux setting
for xusb_hs_src and treats it as a fixed-factor clock. It is,
however, a mux which can be parented by either xusb_ss_src/2 or
pll_u_60M. Add the fixed-factor clock xusb_ss_div2 and put an
entry in periph_clks[] for the xusb_hs_src

The parent-to-index mapping for xusb_fs_src is incorrect.
Fix it by adding a mux table.
