[PATCH 10/18] tty: serial: fsl_lpuart: support suspend/resume

In order to allow wake support in STOP sleep mode, clocks are needed. Use imx_clk_gate2_cgr to disable automatic clock gating in low power mode STOP. This allows to enable wake by UART using: echo enabled > /sys/class/tty/ttyLP0/power/wakeup However, if wake is not enabled, the driver should

[PATCH 15/18] ARM: vf610: PM: initial suspend/resume support

Add system suspend and resume support for Vybrid SoC. The standby sleep state puts the SoC in STOP mode. The SoC can be woken through an interrupt from GPC (Global Power Controller). The GPC can use any interrupt as wake-up source. To save power the main PLL1 is bypassed and uses the 24MHz on-chip

To use self-refresh mode for DDR3 SDRAM memory in LPSTOPx mode, the hardware need to have pull-ups/downs populated on RESET/CKE line of the DDR memory. Read the device tree property which indicates whether a given board has such resistors populated. Signed-off-by: Stefan Agner
