Both CPU-freq and dev-freq drivers support proper regulator lookup from
device-tree, so the early introduced hacks for registering main ARM VDD
regulator under 'vdd_arm' name are no longer needed. Similar for devfreq.
Fix this by removing the obsolete comments and changing the regulator
names to the one, which match the schematics and style for the given
board.

Fix up inconsistent usage of upper and lowercase letters in "Samsung"
and "Exynos" names.
"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked
names. Therefore they should be written with lowercase letters starting
with capital letter.
The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.
Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in

The datasheet of S2MPS11 PMIC is slightly non-consistent in buck[78]
voltage regulators values.
1. The voltage tables for configuring their registers mention range of
voltages: 0.750 V to 3.55 V,
2. The constrains in electrical specifications say output voltage range
to be different (buck7: 1.2 V to 1.5 V, buck8: 1.8 V to 2.1 V).
Adjust the ranges to match the electrical specifications to stay on the
safe side. Anyway these regulators stay at default value so this should
not have effect.

The eMMC memory is supplied by LDO18 (PVDD_EMMC_1V8) and buck10
(PVDD_EMMCF_2V8), not by LDO10. The LDO10 (PVDD_PRE_1V8) supplies
instead VDDP_MMC pin of eMMC host interface and it is already marked as
always on.
This change only properly models the hardware and reflects in usage of
regulators. There is no functional change because:
1. LDO18 cannot be turned off (e.g. by lack of consumers) because in
off mode it is controlled by LDO18EN pin, which is pulled up by
always-on regulator LDO2 (PVDD_APIO_1V8).
2. LDO10 is marked as always on so removing its consumer will not have
effect.

Add the PMIC regulator suspend configuration to Arndale Octa board to
reduce power usage during suspend and keep necessary regulators on. The
configuration is based on vendor (Insignal) reference kernel and the
board datasheet. Comparing to vendor kernel, additionally turn off in
suspend all regulators controlled by external pin (LDO3, LDO7, LDO18 and
buck10).
This is purely for hardware description because board does not support
Suspend to RAM and the S2MPS11 driver does not support

The PVDD_APIO_1V8 (LDO2) and PVDD_ABB_1V8 (LDO8) regulators were turned
off by Linux kernel as unused. However they supply critical parts of
SoC so they should be always on:
1. PVDD_APIO_1V8 supplies SYS pins (gpx[0-3], PSHOLD), HDMI level shift,
RTC, VDD1_12 (DRAM internal 1.8 V logic), pull-up for PMIC interrupt
lines, TTL/UARTR level shift, reset pins and SW-TACT1 button.
It also supplies unused blocks like VDDQ_SRAM (for SROM controller) and
VDDQ_GPIO (gpm7, gpy7).
The LDO2 cannot be turned off (S2MPS11 keeps it on anyway) so
marking it "always-on" only reflects its real status.
2. PVDD_ABB_1V8 supplies Adaptive Body Bias Generator for ARM cores,
memory and Mali (G3D).

is property of the board - configurable by pulling up/down gpg2-1).
To make user-visible CPU ordering more consistent the 'cpus' node was
overridden by exynos5422-cpus.dtsi.
However this is a little bit ugly and error-prone. Overriding the CPU
child nodes requires to basically reverse what was done initially in

Instead, split CPU configuration entirely to separate files which should

The Exynos5420 SoC has 3 sets of 8 pads used as data lines for the 3
MMC/SD/SDIO slots. These needs to be muxed as SD_n_DATA instead of a
GPIO or external interrupt to allow the MMC controller to communicate
with the attached cards or SDIO devices.
Which data lines needs to be muxed as SD_n_DATA depends on the bus
width used for data transfer:
* bus-width = <1> needs SD_n_DATA[0]
* bus-width = <4> needs SD_n_DATA[0-3]
* bus-width = <8> needs SD_n_DATA[0-7]
The Exynos5250-pinctrl.dtsi file that defines the groups of pins has
SD_n_DATA[0] muxed for both sdn_bus1 and sdn_bus4 so just one of them
needs to be included in the device node's pinctrl property.
But Exynos5420-pinctrl has a different definition and only includes
SD_n_DATA[1-3] for sdn_bus4. So for a bus-width = <4>, both sdn_bus1
and sdn_bus4 have to be in the dev pinctrl to mux all the needed pads.
It seems all Exynos5420 boards had just cargo cult the pinctrl lines
assuming that sdn_bus4 also included SD_n_DATA[0] and it only works
because the bootloader muxes the pads correctly. But that is not the
case for the devices not used by the bootloader such as WiFi modules.
Add sdn_bus1 too in the nodes pinctrl to not rely on the bootloader.

Regulators for MMC2 (SD card) are PVDD_TFLASH_2V8 (LDO19) for vmmc
and PVDD_APIO_MMCOFF_2V8 (LDO13) for vqmmc. Currently the device
tree entry for MMC2 uses PVDD_PRE_1V8 (LDO10) for vmmc and vqmmc is
not specified. Fix it.
Without this patch:
- "mmc: dw_mmc: use mmc_regulator_get_supply to handle regulators"
patch causes a SD card detection to fail
- "mmc: dw_mmc: Support voltage changes" patch causes a boot hang
This patch fixes both above problems.

dw-mmc controller can support multiple slots.
But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
"supports-highspeed" property can be replaced with "cap-sd/mmc-highspeed".

This change places MDMA1 in disabled node for Exynos5420.
If MDMA1 region is configured with secure mode, it makes
the boot failure with the following on smdk5420 board.
("Unhandled fault: imprecise external abort (0x1406) at 0x00000000")
Thus, arndale-octa board don't need to do the same thing anymore.
