Subject[RFCv1 0/5] Odroid N2 failes to boot using upstream kernel & u-boot
Date
We am trying to build the upstream u-boot and upstream kernel,
but it fails to pass the initialization of PWM_MESON driver.
So these patches help boot the kernel on microSD card.

Patchs based on Linux 5.4-rc2

Boot log failed are shown below.

[ 1.569240] meson-gx-mmc ffe05000.sd: Got CD GPIO
[ 1.599227] pwm-regulator regulator-vddcpu-a: Failed to get PWM: -517

[ 1.613273] pwm-regulator regulator-vddcpu-b: Failed to get PWM: -517
[ 1.619931] hctosys: unable to open rtc device (rtc0)

My guess their is not much issue with eMMC module, if their is
other approach to resolve this issue, I will give this a try.
