Some boards are running with secure firmware running in TrustZone secure
world, which changes the way some things have to be initialized.
This patch adds an interface for platforms to specify available firmware
operations and call them.
A wrapper macro, call_firmware_op(), checks if the
Some boards use secure monitor calls to communicate with secure
firmware.
This patch adds exynos_smc function which uses smc assembly instruction
to do secure monitor calls.
This is a follow-up on the patch by Kyungmin Park:
[PATCH v5 2/2] ARM: EXYNOS: SMC instruction (aka firmware) support
Some Exynos-based boards contain secure firmware and must use firmware
operations to set up some hardware.
This patch adds firmware operations for Exynos secure firmware and a way
for board code and device tree to specify that they must be used.
Example of use:
In board code:
Boards using secure firmware must use different CPU boot registers and
call secure firmware to boot the CPU.

This patchset does following:
Patch 1: Segregate and move common code to new function
Patch 2: Adds C2 idle state
It has been tested on Kukjin's for-next branch on Origen board.
Chander Kashyap (2):
ARM: Exynos4: CPUIDLE: Add generic function for exynos4 cpuidle
ARM: EXYNOS4: CPUIDLE: Add
Moved out the code from exynos4_enter_core0_aftr to a separate
function exynos4_do_idle in order to make it usable for other
idle states.
Also update the wakeup mask without touching reserved bits.

To enter into c2 state:
1. ARM should be off
2. All local power domains should be off
3. All IPs belonging to TOP domain should not be in use
In this state TOP domain remains in retention state.

This patch enables device tree based discovery support for DP driver.
The driver is modified to handle platform data in both the cases:
with DT and non-DT.
DP-PHY should be regarded as a seperate device node while
being passed from device tree list, and device node for
DP should contain DP-PHY as
When s3c64xx-spi is instantiated from device tree an instance of
struct s3c64xx_spi_csinfo is dynamically allocated in the driver.
For non-dt platform it is passed from board code through
spi_register_board_info(). On error path in s3c64xx_spi_setup()
function there is an attempt to free this data
Add hardware event/error counters which can be dumped into the kernel
log through VIDIOC_LOG_STATUS ioctl. The counters are reset in each
s_stream(1) call. Any errors are logged after streaming is turned off.
