-Subject: [PATCH] MIPS: ath79: fix AR724X_PLL_REG_PCIE_CONFIG offset
-
-According to the QCA u-boot source the "PCIE Phase Lock Loop
-Configuration (PCIE_PLL_CONFIG)" register is for all SoCs except the
-QCA955X and QCA956X at offset 0x10.
-
-Since the PCIE PLL config register is only defined for the AR724x fix
-only this value. The value is wrong since the day it was added and isn't
-yet used by any driver.

-Subject: [PATCH] net: qmi_wwan: add BroadMobi BM806U 2020:2033
-
-BroadMobi BM806U is an Qualcomm MDM9225 based 3G/4G modem.
-Tested hardware BM806U is mounted on D-Link DWR-921-C3 router.
-The USB id is added to qmi_wwan.c to allow QMI communication with
-the BM806U.
-
-Tested on 4.14 kernel and OpenWRT.
