- Rebased the patches for 4.14
- Dropped spi-qup and 0027, 0028, 0029
clk patches since it's already included
in upstream.
Tested on IPQ AP148 Board:
1) NOR boot and NAND boot
2) Tested USB and PCIe interfaces
3) WDOG test
4) cpu frequency scaling
5) ethernet, 2G and 5G WiFi
6) ubi sysupgrade

Subject: [PATCH 01/69] dtbindings: qcom_adm: Fix channel specifiers
|
|
|
|
Original patch from Andy Gross.
|
|
|
|
This patch removes the crci information from the dma
|
|
channel property. At least one client device requires
|
|
using more than one CRCI value for a channel. This does
|
|
not match the current binding and the crci information
|
|
needs to be removed.
|
|
|
|
Instead, the client device will provide this information
|
|
via other means.
