2017-10-08ARM: dts: am335x-chilisom: Wakeup from RTC-only state by power on eventMarcin Niestroj
[ Upstream commit ca244a83ecc7f0a9242ee2116e622cb6d7ec2a90 ] On chiliSOM TPS65217 nWAKEUP pin is connected to AM335x internal RTC EXT_WAKEUP input. In RTC-only state TPS65217 is notifying about power on events (such as power buton presses) by setting nWAKEUP output low. After that it waits 5s for proper device boot. Currently it doesn't happen, as the processor doesn't listen for such events. Consequently TPS65217 changes state from SLEEP (RTC-only state) to OFF. Enable EXT_WAKEUP input of AM335x's RTC, so the processor can properly detect power on events and recover immediately from RTC-only states, without powering off RTC and losing time.

2016-04-14ARM: dts: am335x-chilisom: Enable poweroff PMIC sequence using RTC signalMarcin Niestroj
ChiliSOM has TPS65217's PWR_EN pin connected to AM335x PMIC_POWER_EN pin. Processor's PMIC_POWER_EN is controlled by it's internal RTC, hence RTC subsystem is responsible for proper board poweroff sequence. This change enables complete poweroff sequence for ChiliBoard, switching PMIC's state from ACTIVE to SLEEP.

2016-04-14ARM: dts: am335x-chili*: Move Ethernet MAC description from SOM to boardMarcin Niestroj
ChiliSOM has 2 Ethernet subsystems with different types of possibly used PHY interfaces (i.e. MII, RMII, GMII, RGMII). Current code configured pinmux for RMII on 1st Ethernet subsystem and enabled Ethernet MAC with 1 slave for all boards which use ChiliSOM. This change moves pinmux configuration of 1st Ethernet subsystem to ChiliBoard description, as this is board-specific.

2016-04-14ARM: dts: am335x-chili*: Move uart0 description from SOM to boardMarcin Niestroj
uart0 configuration code has been in SOM. However, it is possible to use all (or none) of 6 uart's of AM335x processor present on ChiliSOM. This fix moves declaration of uart0 from ChiliSOM to ChiliBoard, because use of uart is strictly board-specific.

2016-04-12ARM: dts: am335x: Provide NAND ready pinRoger Quadros
On these boards NAND ready pin status is avilable over GPMC_WAIT0 pin. For NAND we don't use GPMC wait pin monitoring but get the NAND Ready/Busy# status using GPIOlib. GPMC driver provides the WAIT0 pin status over GPIOlib. Read speed increases from 7869 KiB/ to 8875 KiB/s and write speed was unchanged at 5100 KiB/s. Measured using mtd_speedtest.ko on am335x-evm.

2016-02-19Revert "regulator: tps65217: remove tps65217.dtsi file"Peter Ujfalusi
This reverts commit 8e6ebfaa9b384088002baa10f7534efa73a0794e. Without the patch reverted regulators will not work. This prevents MMC to be working for example so the boards can not boot to MMC rootfs. Tested it on beaglebone white and bisect also points to the reverted commit. The issue can be also fixed by adding "regulator-compatible =" to all board dts file for the regulators.
