ARM: dts: rockchip: rk3368-sheep add vsel gpio for syr827
Add vsel gpio for syr827, which is PMIC_SLEEP in hardware pcb.
The driver will parse the gpio and use it to indicate the chip
work status, as the following codes:
static int fan53555_is_enabled ()
if defined vsel_gpio
gpiod_get_raw_value
else
regmap_read
Before the patch, the log shows:
CPU4: update cpu_capacity 1024
CPU4: Booted secondary processor [410fd033]
cache: parent cpu4 should not be sleeping
rk3x-i2c ff650000.i2c: timeout, ipd: 0x10, state: 1
Since cpu4 is the base core for cluster1, which need to initialize
cpufreq during boot up, finally call fan53555_is_enabled. But the
i2c is suspended at that time, can't get interrupt until timeout.
