Following arm64 commit bc3ee18a7a57 (arm64: init: Move of_clk_init to time_init()), vexpress_osc_of_setup() is called via of_clk_init() long before initcalls are issued. Initialising the vexpress oscillators requires the vespress sysregs to be already initialised, so this patch adds an explicit call to vexpress_sysreg_of_early_init() in vexpress oscillator setup function.

OMAP4 ISS Driver
================
Introduction
------------
The OMAP44XX family of chips contains the Imaging SubSystem (a.k.a. ISS),
Which contains several components that can be categorized in 3 big groups:
- Interfaces (2 Interfaces: CSI2-A & CSI2-B/CCP2)
- ISP (Image Signal Processor)
- SIMCOP (Still Image Coprocessor)
For more information, please look in [1] for latest version of:
"OMAP4430 Multimedia Device Silicon Revision 2.x"
As of Revision AB, the ISS is described in detail in section 8.
This driver is supporting _only_ the CSI2-A/B interfaces for now.
It makes use of the Media Controller framework [2], and inherited most of the
code from OMAP3 ISP driver (found under drivers/media/platform/omap3isp/*),
except that it doesn't need an IOMMU now for ISS buffers memory mapping.
Supports usage of MMAP buffers only (for now).
Tested platforms
----------------
- OMAP4430SDP, w/ ES2.1 GP & SEVM4430-CAM-V1-0 (Contains IMX060 & OV5640, in
which only the last one is supported, outputting YUV422 frames).
- TI Blaze MDP, w/ OMAP4430 ES2.2 EMU (Contains 1 IMX060 & 2 OV5650 sensors, in
which only the OV5650 are supported, outputting RAW10 frames).
- PandaBoard, Rev. A2, w/ OMAP4430 ES2.1 GP & OV adapter board, tested with
following sensors:
* OV5640
* OV5650
- Tested on mainline kernel:
