[PATCH v2] ARM: vexpress_defconfig: Enable voltage regulators

by Christoffer Dall

Enable voltage regulators by default for versatile express. This should work on all verstatile express platforms and not enabling it prevents a defconfig'ed kernel from using the SD card controller on the qemu emulated platform, which is unfortunate for first-time casual users.

[PATCH 00/25] tty: serial: drop uart_port->lock before calling

by Viresh Kumar

The -rt patch triggers a lockdep warning for serial drivers if tty_flip_buffer_push() is called with uart_port->lock locked. This never shows up on UP kernels. Release the port lock before calling tty_flip_buffer_push() and reacquire it after the call. Similar stuff was already done for few other drivers in the past, like: commit 2389b272168ceec056ca1d8a870a97fa9c26e11a Author: Thomas Gleixner <tglx(a)linutronix.de> Date: Tue May 29 21:53:50 2007 +0100 [ARM] 4417/1: Serial: Fix AMBA drivers locking This is neither tested nor compiled.

Since vexpress_defconfig is known broken (https://bugs.launchpad.net/linaro-ci/+bug/1212893), what's the next step to move forward?

[PATCH v4 0/3] Add RTC DT node to Exynos5420 SoC and Fix RTC DT node name for 5250 Soc

by Vikas Sajjan

This patchset does the following 3 things: 1) Fixes the RTC DT node name for Exynos5250 SoC 2) Updates the status of RTC DT node of Exynos5250 SoC to "okay" 3) Adds RTC DT node to Exynos5420 SoC changes since v3: - split the 5250 related modifications into 2 separate patch as suggested by Tomasz Figa <t.figa(a)samsung.com> changes since v2: - split the 5250 related modifications into a separate patch. - placed the RTC node as per the alphabetical order in the DTS file as suggested by Kukjin Kim <kgene(a)kernel.org>. changes since v1: - made DT node status as "okay" in the dtsi file itself.
