Subject: [RFCv1 0/5] Odroid N2 failes to boot using upstream kernel & u-boot

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.

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.
