This patchset adds new board dts file for Samsung Rinato board (Gear 2) which
is based on Exynos3250 SoC and adds sleep mode pin configuration using pinctrl
subsystem to reduce leakage power-consumption in sleep state.
This patchset is based on linux-samsung.git (for-next branch).
Changes from v2:
- Separate patch3 from patchset[1] and then this patchset includes patch3.
After applied patch3, the power-consumption of Rinato board is 0.6mA in suspend state.
[1] [PATCHv5 0/3] regulator: of: Add support for parsing regulator suspend state
: https://lkml.org/lkml/2014/10/10/161
- Change PDN (Power-down mode) state for GPE0-3 (BT_UART_RTS) because Rinato
board uses UART1 for bluetooth device. BT_UART_RTS pin should be disabled in
suspend state by setting high state of GPE0-3
- Turn on always the regulator state of VAP_VMIPI_1.0V because if VAP_VMIPI_1.0V
is off state or would be not controlled by DRM driver, happen imprecise external abort.
Changes from v1:
- Remove useless brace
- Remove unneeded 'regulators' keyword
- Consolidate memory information in one entry

1.8.5.5
This patch add support for device tree sources for Samsung Rinato baord
(Gear 2) based on Exynos3250 SoC.
This dts file support following features:
- eMMC
- Main PMIC (Samsung S2MPS14)
- Interface PMIC (Maxim MAX77836, MUIC, fuel-gauge, charger)
- RTC of Exynos3250
- ADC of Exynos3250 with NTC thermistor
- I2S of Exynos3250
- TMU of Exynos3250
- MFC of Exynos3250
- Secure firmware for Exynos3250 secondary cpu boot
- Serial ports of Exynos3250
- gpio-key for power key

I suspect a typo in this email address. Kukjin, is this something you
could fix up when applying (other patches in this series have it correct)?

Hi Chanwoo,
I wonder if this regulator-fixed is needed. The LDO11 and LDO12 has
external GPIO control set up. So maybe this could be removed?

OK, I'll remove 'vemmc_reg' and then use ldo12_reg insead of 'vemmc_reg' on mshc_0 dt node.
