* ARM: dts: correct the mmc0 capability string for exynos Peach boardsNaveen Krishna Chatradhi2014-10-211-1/+1
| | | | | | | | | | | | MMC capability for HS200 is parsed in mmc/core/host.c as dts string "mmc-hs200-1_8v". This patch corrects the dts string for Exynos5420 based peach-pit and Exynos5800 based peach-pi boards.

* ARM: dts: Add rtc_src clk for s3c-rtc on exynos Peach boardsJavier Martinez Canillas2014-10-211-1/+4
| | | | | | | | | | | | | commit 546b117fdf17 ("rtc: s3c: add support for RTC of Exynos3250 SoC") added an "rtc_src" DT property for the Samsung's S3C Real Time Clock controller that specifies the 32.768 kHz clock that uses the RTC as its source clock. In the case of the Peach Pit and Pi machines, the Maxim 77802 32kHz AP clock is used as the source clock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | In case the optional dr_mode property isn't set in the dwc3 nodes the the controller will go into OTG mode if both USB host and USB gadget functionality are enabled in the kernel configuration. Unfortunately this results in USB not working on exynos5420-peach-pit and exynos5800-peach-pi with such a kernel configuration unless manually change the mode. To resolve that explicitly configure the dual role mode as host.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DeviceTree files for the Peach Pit and Pi machines have a simplistic model of the connections between the different regulators since not all the tps65090 regulators get their input supply voltage from the VDC. DCDC1-3, LD0-1 and fet7 parent supply is indded VDC but the fet1-6 get their input supply from the DCDC1 and DCDC2 output voltage rails. Update the DeviceTree to better reflect the real connections between tps65090 regulators. Having this information in the DTS is useful since FETs are switches that don't provide an output voltage so the regulator core needs to fetch the FET parent output voltage if the child voltage is queried.

* ARM: dts: Add mask-tpm-reset node in exynos5800-peach-piVikas Sajjan2014-07-161-0/+12
| | | | | | | | | | | | | | | | | The mask-tpm-reset GPIO is used by the kernel to prevent the TPM from being reset across sleep/wake. If we don't set it to anything then the TPM will be reset. U-Boot will detect this as invalid and will reset the system on resume time. This GPIO can always be low and not hurt anything. It will get pulled back high again during a normal warm reset when it will default back to an input. To properly preserve the TPM state across suspend/resume and to make the chrome U-Boot happy, properly set the GPIO to mask the reset to the TPM.
