soc: mediatek: Add compile dependency to pmic-wrapper

2015-05-27T14:27:05Z

The pmic-wrapper calls the reset controller. If CONFIG_RESET_CONTROLLER is not set, compilation fails with: drivers/soc/mediatek/mtk-pmic-wrap.c: In function ‘pwrap_probe’: drivers/soc/mediatek/mtk-pmic-wrap.c:836:2: error: implicit declaration of function ‘devm_reset_control_get’ [-Werror=implicit-function-declaration] This patch sets the dependency in the Kconfig file.

soc: mediatek: PMIC wrap: Fix register state machine handling

2015-05-27T12:11:41Z

When the PMIC wrapper state machine has read a register it goes into the "wait for valid clear" (vldclr) state. The state machine stays in this state until the VLDCLR bit is written to. We should write this bit after reading a register because the SCPSYS won't let the system go into suspend as long as the state machine waits for valid clear. Since now we never leave the state machine in vldclr state we no longer have to check for this state on pwrap_read/pwrap_write entry and can remove the corresponding code.

soc: mediatek: PMIC wrap: Fix clock rate handling

2015-05-27T12:11:41Z

replace chipselect extension values based on SPI clock with hardcoded SoC specific values. The PMIC wrapper has the ability of extending the chipselects by configurable amounts of time. We configured the values based on the rate of SPI clock, but this is wrong. The delays should be configured based on the internal PMIC clock that latches the values from the SPI bus to the internal PMIC registers. By default this clock is 24MHz. Other clock frequencies are for debugging only and can be removed from the driver. Signed-off-by: Sascha Hauer Signed-off-by: Matthias Brugger

soc: mediatek: Add PMIC wrapper for MT8135 and MT8173 SoCs

2015-03-30T10:25:40Z

This adds support for the PMIC wrapper found on MediaTek MT8135 and MT8173 SoCs. The PMIC wrapper is found on MT6xxx SoCs aswell but these are currently not supported. On MediaTek MT8135, MT8173 and other SoCs the PMIC is connected via SPI. The SPI master interface is not directly visible to the CPU, but only through the PMIC wrapper inside the SoC. The communication between the SoC and the PMIC can optionally be encrypted. Also a non standard Dual IO SPI mode can be used to increase speed. The MT8135 also supports a special feature named "IP Pairing". With IP Pairing the pins of some SoC internal peripherals can be on the PMIC. The signals of these pins are routed over the SPI bus using the pwrap bridge. Because of these optional non SPI conform features the PMIC driver is not implemented as a SPI bus master driver.
