The patches for ODROID-C2/C4 don't apply to Linux 5.12 used in
ODROID-N2. Move ODROID-C2/C4 patches to kernel version specific
directory so they don't get applied for ODROID-N2.
Use the latest Linux stable release 5.12 for ODROID-N2. This allows to
test if we see the random kernel crashes observed with 5.10 in latest
stable 5.12 as well.
Since the move to 5.10 multiple users experience stability issues
leading to random crashes. All reboots follow a SError Interrupt:
[48112.247242] SError Interrupt on CPU5, code 0xbf000000 -- SError
...
Revert back to Linux 5.9.16 for now.
It seems that the crash of the Meson DRM driver on shutdown can also be
fixed by compiling it in. The driver is also built-in in LibreELEC,
hence this is better tested by the upstream community.
Note the underlying issue seems to be a disabled clock: Since the
introduction of meson_drv_shutdown some registers are touched at a very
late stage. Those clock get disabled in meson_ee_pwrc_shutdown. It seems
that when the driver is built-in, meson_drv_shutdown gets called before
meson_ee_pwrc_shutdown and hence sidesteps the problem.
Note: This increases the kernel by a bit since DRM needs to be built-in
as well. Configure some less common used file systems as modules
(ext3/NFS).
In Linux 5.10.24 a regression has been introduced which broke reboot on
ODROID-N2(+). Interestingly the patch should improve reboot stability
for VIM3, which uses the same SoC. However, it seems that in the
ODROID-N2 case, this causes more problems then it fixes. Revert the
offending patch.
* Drop ODROID specific kernel update script
With the jump to Linux 5.10 LTS we can use the same upstream kernel for
Hardkernel ODROID boards as well. Extend the update-kernel-upstream.sh
to support the ODROID boards.
* Linux: Update kernel 5.10.13
Fix ethernet PHY reset timing to make sure the link comes up when
reconfiguring the link.
Also drop 0006-clk-meson-g12a-mark-fclk_div2-as-critical.patch which has
been applied in v5.9.2 stable release.
* Make sure to set board_rev for N2+ correctly
For some reason the code to set the environment did not make it into the
ODROID N2 board code. Fix the patch to correctly set board_rev for N2(+).
Also remove the w400 patch as it is no longer required.
* Use latest ODROID-N2+ patches
Use the queued patches (and fixes) for upstream ODROID-N2+ support.
This uses the clock settings from meson-g12b-a311d.dtsi running the
CPUs at the following clocks:
- 4xA73@2.2GHz
- 2xA53@1.8GHz
Instead of reverting the CDC ACM cool-down patch fix the intention of
that change. This should fix the error recovery paths in the CDC ACM
driver and allow CDC ACM devices to continue working even in the event
of USB issues.
Revert CDC ACM cool-down patch. This should fix the error recovery paths

in the event of USB issues.
* Bump ODROID boards to Linux 5.9.1
This makes quite some patches obsolete which since have been upstreamed.
* Drop Linux 5.7 header symbols
Since we do not introduce new packages which actually require a newer
kernel headers, there is no value in having config symbols for the new
kernel version. Buildroot is still using the headers from our kernel,
and hence gets the latest version of the headers.
* Add ODROID-N2+ support
Add ODROID-N2+ support with the new SoC revision c. Extend the U-Boot
script: Assume ODROID-N2 if the SoC revision is "a" (there are only "a"
revision SoCs on ODROID N2) and assume N2+ otherwise.
Currently using overclock mode as proposed in the upstream kernel patches.
* Update hassos-hook.sh
