8c38b5d03d MX53: add function to set SATA clock to internal
The MX53 SATA interface can use an internal clock (USB PHY1)
instead of an external clock. This is an undocumented feature, but used
on most Freescale's evaluation boards, such as MX53-loco.

As stated by Freescale's support:

Fuses (but not pins) may be used to configure SATA clocks.
Particularly the i.MX53 Fuse_Map contains the next information
about configuring SATA clocks :
	SATA_ALT_REF_CLK[1:0] (offset 0x180C)

'00' - 100MHz (External)
'01' - 50MHz (External)
'10' - 120MHz, internal (USB PHY)
'11' - Reserved

2c7396cb1a EXYNOS: support EXYNOS MIPI DSI interface driver.
EXYNOS SoC platform has MIPI-DSI controller and MIPI-DSI
based LCD Panel could be used with it. This patch supports MIPI-DSI driver
based Samsung SoC chip.

LCD panel driver based MIPI-DSI should be registered to MIPI-DSI driver at
board file and LCD panel driver specific function registered to mipi_dsim_ddi
structure at lcd panel init function called system init.
In the MIPI-DSI driver, find lcd panel driver by using registered
lcd panel name, and then initialize lcd panel driver.

f2ae6c1a83 OMAP4: scale voltage of core before MPU scales
OMAP4 requires that parent domains scale ahead of dependent domains.
This is due to the restrictions in timing closure. To ensure
a consistent behavior across all OMAP4 SoC, ensure that
vdd_core scale first, then vdd_mpu and finally vdd_iva.

As part of doing this refactor the logic to allow for future
addition of OMAP4470 without much ado. OMAP4470 uses different
SMPS addresses and cannot be introduced in the current code
without major rewrite.

3acb553439 OMAP4460: TPS Ensure SET1 is selected after voltage configuration
TPS SET0/SET1 register is selected by a GPIO pin on OMAP4460 platforms.
Currently we control this pin with a mux configuration as part of
boot sequence.
Current configuration results in the following voltage waveform:
                           |---------------| (SET1 default 1.4V)
                           |               --------(programmed voltage)
                           | <- (This switch happens on mux7,pullup)
vdd_mpu(TPS)         -----/ (OPP boot voltage)
                                             --------- (programmed voltage)
vdd_core(TWL6030)    -----------------------/ (OPP boot voltage)
Problem 1)                |<----- Tx ------>|
   timing violation for a duration Tx close to few milliseconds.
Problem 2) voltage of MPU goes beyond spec for even the highest of MPU OPP.

By using GPIO as recommended as standard procedure by TI, the sequence
changes to:
                                  -------- (programmed voltage)
vdd_mpu(TPS)         ------------/ (Opp boot voltage)
                                   --------- (programmed voltage)
vdd_core(TWL6030)    -------------/ (OPP boot voltage)

a78274b205 OMAP3+: Introduce generic logic for OMAP voltage controller
OMAP Voltage controller is used to generically talk to
PMICs on OMAP3,4,5 over I2C_SR. Instead of replicating code
in multiple SoC code, introduce a common voltage controller
logic which can be re-used from elsewhere.

With this change, we replace setup_sri2c with omap_vc_init which
has the same functionality, and replace the voltage scale
replication in do_scale_vcore and do_scale_tps62361 with
omap_vc_bypass_send_value. omap_vc_bypass_send_value can also
now be used with any configuration of PMIC.

NOTE: Voltage controller controlling I2C_SR is a write-only data
path, so no register read operation can be implemented.

	  interface, so it can not modify the ENV parameters stored in
	  master's NOR flash using "saveenv" or other commands.

Master needs to:
	1. Put the slave's ENV into it's own memory space.
	2. Set an inbound SRIO window covered slave's ENV stored in master's
	   memory space.
Slave needs to:
	1. Set a specific TLB entry in order to fetch ucode and ENV from master.
	2. Set a LAW entry with the TargetID SRIO1 or SRIO2 for ucode and ENV.

3f1af81b80 powerpc/corenet_ds: Slave uploads ucode when boot from SRIO
When boot from SRIO, slave's ucode can be stored in master's memory space,
then slave can fetch the ucode image through SRIO interface. For the
corenet platform, ucode is for Fman.

Master needs to:
	1. Put the slave's ucode image into it's own memory space.
	2. Set an inbound SRIO window covered slave's ucode stored in master's
	   memory space.
Slave needs to:
	1. Set a specific TLB entry in order to fetch ucode from master.
	2. Set a LAW entry with the TargetID SRIO1 or SRIO2 for ucode.

5ffa88eca7 powerpc/corenet_ds: Master module for boot from SRIO
For the powerpc processors with SRIO interface, boot location can be configured
from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash
for u-boot image. The image can be fetched from another processor's memory
space by SRIO link connected between them.

The processor boots from SRIO is slave, the processor boots from normal flash
memory space and can help slave to boot from its memory space is master.
They are different environments and requirements:

master:
	1. NOR flash for its own u-boot image, ucode and ENV space.
	2. Slave's u-boot image in master NOR flash.
	3. Normally boot from local NOR flash.
	4. Configure SRIO switch system if needed.
slave:
	1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
	2. Boot location should be set to SRIO1 or SRIO2 by RCW.
	3. RCW should configure the SerDes, SRIO interfaces correctly.
	4. Slave must be powered on after master's boot.

For the master module, need to finish these processes:
	1. Initialize the SRIO port and address space.
	2. Set inbound SRIO windows covered slave's u-boot image stored in
	   master's NOR flash.
	3. Master's u-boot image should be generated specifically by
	   make xxxx_SRIOBOOT_MASTER_config
	4. Master must boot first, and then slave can be powered on.
