From 69f22be7b10684ade3808de22db87c536ed135f3 Mon Sep 17 00:00:00 2001
From: Igor Grinberg <grinberg@compulab.co.il>

Subject: ARM: pxa: add U2D controller and ULPI driver for pxa3xx

USB2.0 Device Controller (U2DC) which is found in Marvell PXA3xx.
U2DC supports both High and Full speed modes.
PXA320 and PXA300 U2DC supports only UTMI interface.
PXA310 U2DC supports only ULPI interface and has the OTG capability.

U2D Controller ULPI driver introduced in this patch supports only the
PXA310 USB Host via the ULPI.

Subject: ARM: pxa: fix pxa3xx-u2d crash when ULPI not used

In case the pxa3xx-u2d driver isn't used, probing of ohci-pxa27x will cause an
ugly kernel crash (NULL pointer dereference in pxa3xx_u2d_start_hc(), because
struct u2d is NULL and clk_enable() call will crash the kernel, trying to access
it).

Subject: ARM: pxa: reduce the scope of get_clk_frequency_khz()

get_clk_frequency_khz() is used in private cpufreq driver. In order to meet
the change of different pxa silicons, checking cpuid is introduced in
get_clk_frequency_khz(). While more pxa silicons are supported, the workload
of checking cpuid is higher.

So restrict the scope of get_clk_frequency_khz() on pxa2xx. Different pxa
silcions use different private cpufreq driver to avoid too much checking
on cpuid.

Subject: ARM: pxa: reduce the scope of get_memclk_frequency_10khz()

Up to now, only pxa2xx pcmcia driver is using the API. No other device driver
is using this API in PXA3xx or any other PXA silicons.

Restrict the scope only on pxa2xx and remove the implementation of pxa3xx. So
we can avoid oo much checking on cpuid after more pxa chips supported.
