+Subject: ARM: dts: exynos: Add minimal clkout parameters to Exynos3250 PMU
+
+From: Marek Szyprowski <m.szyprowski@samsung.com>
+
+commit a66352e005488ecb4b534ba1af58a9f671eba9b8 upstream.
+
+Add minimal parameters needed by the Exynos CLKOUT driver to Exynos3250
+PMU node. This fixes the following warning on boot:
+
+exynos_clkout_init: failed to register clkout clock
+
+Fixes: d19bb397e19e ("ARM: dts: exynos: Update PMU node with CLKOUT related data")

+Subject: ARM: dts: exynos: Fix max voltage for buck8 regulator on Odroid XU3/XU4
+
+From: Marek Szyprowski <m.szyprowski@samsung.com>
+
+commit a3238924a820c1d7c977b632b769f3b5690cba09 upstream.
+
+The maximum voltage value for buck8 regulator on Odroid XU3/XU4 boards is
+set too low. Increase it to the 2000mV as specified on the board schematic.
+So far the board worked fine, because of the bug in the PMIC driver, which
+used incorrect step value for that regulator. It interpreted the voltage
+value set by the bootloader as 1225mV and kept it unchanged. The regulator
+driver has been however fixed recently in the commit 56b5d4ea778c
+("regulator: s2mps11: Fix steps for buck7, buck8 and LDO35"), what results
+in reading the proper buck8 value and forcing it to 1500mV on boot. This
+is not enough for proper board operation and results in eMMC errors during
+heavy IO traffic. Increasing maximum voltage value for buck8 restores
+original driver behavior and fixes eMMC issues.

+Subject: ARM: dts: exynos: Fix pinctrl definition for eMMC RTSN line on Odroid X2/U3
+
+From: Marek Szyprowski <m.szyprowski@samsung.com>
+
+commit ec33745bccc8f336957c751f4153421cc9ef5a54 upstream.
+
+Commit 225da7e65a03 ("ARM: dts: add eMMC reset line for
+exynos4412-odroid-common") added MMC power sequence for eMMC card of
+Odroid X2/U3. It reused generic sd1_cd pin control configuration node
+and only disabled pull-up. However that time the pinctrl configuration
+was not applied during MMC power sequence driver initialization. This
+has been changed later by commit d97a1e5d7cd2 ("mmc: pwrseq: convert to
+proper platform device").
+
+It turned out then, that the provided pinctrl configuration is not
+correct, because the eMMC_RTSN line is being re-configured as 'special
+function/card detect function for mmc1 controller' not the simple
+'output', thus the power sequence driver doesn't really set the pin
+value. This in effect broke the reboot of Odroid X2/U3 boards. Fix this
+by providing separate node with eMMC_RTSN pin configuration.

+Subject: arm64: dts: hikey: Give wifi some time after power-on
+
+From: Jan Kiszka <jan.kiszka@siemens.com>
+
+commit 83b944174ad79825ae84a47af1a0354485b24602 upstream.
+
+Somewhere along recent changes to power control of the wl1835, power-on
+became very unreliable on the hikey, failing like this:
+
+wl1271_sdio: probe of mmc2:0001:1 failed with error -16
+wl1271_sdio: probe of mmc2:0001:2 failed with error -16
+
+After playing with some dt parameters and comparing to other users of
+this chip, it turned out we need some power-on delay to make things
+stable again. In contrast to those other users which define 200 ms, the
+hikey would already be happy with 1 ms. Still, we use the safer 10 ms,
+like on the Ultra96.

+
+From: Alistair Strachan <astrachan@google.com>
+
+commit 8d26c1390aec795d492b8de5e4437751e8805a1d upstream.
+
+This reverts commit abd7d0972a192ee653efc7b151a6af69db58f2bb. This
+change was already partially reverted by John Stultz in
+commit 9c6d26df1fae ("arm64: dts: hikey: Fix eMMC corruption regression").
+
+This change appears to cause controller resets and block read failures
+which prevents successful booting on some hikey boards.
