We currently have a different clock rate for droid4 compared to the
stock v3.0.8 based Android Linux kernel:
# cat /sys/kernel/debug/clk/dpll_*_m7x2_ck/clk_rate
266666667
307200000
# cat /sys/kernel/debug/clk/l3_gfx_cm:clk:0000:0/clk_rate
307200000
Let's fix this by configuring sgx to use 153.6 MHz instead of 307.2 MHz.
Looks like also at least duover needs this change to avoid hangs, so
let's apply it for all 4430.
This helps a bit with thermal issues that seem to be related to memory
corruption when using sgx. It seems that other driver related issues
still remain though.

Reduces attack surface on kernel devs opening the links for MITM

Deterministic algorithm:

For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

The "cooling-min-level" and "cooling-max-level" properties are not
parsed by any part of the kernel currently and the max cooling state of
a CPU cooling device is found by referring to the cpufreq table instead.
Remove the unused properties from the CPU nodes.

Currently the slope and offset values for calculating the

of driver data. Pass them here instead and obtain the values
while of node parsing.

This patch creates a unique node for each clock in the OMAP4 power,

different clock tree which is taken into account in the data.

OMAP4430 devices can reach high temperatures and thus
needs to have cpufreq-cooling on systems running on it.
This patch adds the required cooling device properties
so that cpufreq-cpu0 driver loads the cooling device.

Add DT OPP table for OMAP443x family of devices. This data is
decoded by OF with of_init_opp_table() helper function.
OPP data here is based on existing opp4xxx_data.c
Since the omap4460 OPP tables would be different from OMAP443x,
introduce an new omap443x.dtsi for 443x specific entries and use
existing omap4.dtsi as the common dtsi file for all OMAP4 platforms.
This is in preparation to use generic cpufreq-cpu0 driver for device
tree enabled boot. Legacy non device tree enabled boot continues to
use omap-cpufreq.c and opp4xxx_data.c.
