Subject: [PATCH v2 0/3] Add initial support for exynos5420-chagallwifi
Date: Sat, 15 Jan 2022 17:27:00 +0100	[thread overview]
Message-ID: <20220115162703.699347-1-henrik@grimler.se> (raw)

Samsung's tablet Galaxy Tab S 10.5" (wifi) has codename chagallwifi
and is one of several tablets released in 2013 - 2014 based on Exynos
5420.  This initial devicetree adds support for accessing device over
USB or UART, and allows using a rootfs in either the internal eMMC or
an external sdcard.  4 out of 8 CPUs are brought up when device boots,
which is the same as on the somewhat similar device
exynos5420-arndale-octa.

Patch 2 is necessary after a secure-firmware node is added, otherwise
device hangs during the CPU1BOOT secure monitor call. Without the
secure-firmware node we are not able to bring up any secondary CPUs.

Changes since v1
================

Fix mmc_0 and usbdrd in patch 3: 
* Remove extra, non supported, options from mmc_0 node 
* Do not set usbdrd supplies. Usb networking does not work with them 
  specified, but it works fine with dummy regulators
